I was recently asked by a colleague, what I thought about various popular cooking oils…in particular, grapeseed, flaxseed, canola, and pumpkin seed oil. Here is a summary.
First of all, all of these oils are oils, and their caloric content is roughly similar, about 50 calories per teaspoon. You will not save calories by choosing a particular oil, and there is no oil you can eat limitless quantities of without the caloric content eventually catching up with you.
Secondly, as far as omega-3 content, any vegetable oil containing omega-3 fatty acids contains ALA, NOT the EPA and DHA found in seafood. Even though some ALA can be converted to DHA, it does not occur in quantities needed to therapeutically treat PCOS, or to maintain the integrity of brain structure in the general population. The reason ALA is important, is that it helps to protect the body from inflammation and when it is consumed in adequate quantities, it allows DHA to do its job. In other words, if all you are doing is taking a few fish oil capsules but not changing your diet, you are not very likely to benefit from the fish oil.
That being said, when you choose oils to cook with, you want to remember that your overall dietary omega 6 to omega 3 ratio should be 10:1 or less, in order to reduce the possibility of insulin resistance. How do these four oils measure up?
I boldfaced the ones I prefer.
Grapeseed oil 696 to 1 Yikes!
Flaxseed oil 0.238 to 1 Now you know why we love flaxseed so much around here. Here is some information on some flaxseed oils you can cook with that you might find interesting.
Canola oil 2 to 1 Whether or not you want to include canola oil in your diet is part of your own food religion. If it fits for you, know its ratio is excellent. If it does not, you may want to investigate the flaxseed oil option listed above.
Pumpkin seed oil 3 to 1 Not bad!
Lard 10 to 1 This surprised me. It also made me feel better about my love of tamales.: )
Butter 8.6 to 1 Even better than lard!
Margarine, stick 11.4 to 1 Don't go there.
Margarine, tub 4.8 to 1 The only problem here is that in order to make a liquid oil solid…it has to be turned into trans fat. Wrong kind of omega-6 oil.
I was asked to clarify some comments I recently made about chia, as they were questioned for their accuracy. I'm all for revisiting and making sure my information is accurate, so here is my response.
First of all, while the information on this blog should be helpful to anyone regardless of whether or not they have PCOS, it IS targeted toward women who have this hormone imbalance. So some of the information I provide is more geared toward their specific nutritional needs and not the apparently healthy population. This should always be kept in mind when reading what I write.
One of the questions about my post was that I stated that taurine is an essential amino acid. There is actually some debate about this. Some experts say no, we can synthesize it. Others call it a conditional amino acid, meaning in some situations it may be essential.
Women with PCOS seem to have something going on in their brain and nervous systems that interferes with everything from mood and appetite regulation to speech and language function. (Simply read the responses to my question last week about the symptoms I listed and you will see what I mean.) Much of the dietary protocol we have developed is actually derived from epilepsy research at Johns Hopkins University, with the premise that calming nervous system excitability makes it easier for the brain and nervous system to function as they should when not under duress. Taurine is an amino acid showing promise as an anti-seizure compound, which makes me wonder whether or not a hyperexcitable brain blows through available taurine much more quickly than a brain that does not have to live under these conditions.
That being said, I am more comfortable with the premise that for the population for whom this blog is written, as well as anyone living with any kind of condition that places stress on the brain (migraines, epilepsy, OCD, anxiety disorder, bipolar disorder, PTSD, schizophrenia, etc.), taurine may actually be an essential amino acid. Research to support my claim still needs to be done, but I am more comfortable being conservative on this one, especially given the responses to last week's questionnaire and the severity of some of the diagnoses I just listed. Better to be safe than sorry.
Secondly, even if the amino acid profile of chia is complete, the total protein content of chia is relatively low. So if we're advocating for a 30% protein diet in a woman who is being advised to consume 1500 calories a day, she is going to need to consume about 113 grams of protein. That translates into your needing, at this protein level, to consume 700 grams of chia per day, just to get your protein needs. That is also 3,430 calories' worth of chia, more than twice your daily calorie needs. And while its amino acid profile is nearly complete, its nutritional profile is not. It contains no vitamin A, vitamin C, vitamin D, vitamin K, thiamine, riboflavin, niacin, vitamin B6, folate, or iron, to name a few.
From an omega-3 standpoint, I did invert the numbers. There is no consistent order by which omega-6 and omega-3 ratios are reported, and though I usually check to be sure I did not flip them, I did not this time. I do apologize for that.
According to http://www.nutritiondata.com/, chia seed contains an omega-6 to omega-3 ratio of 3.03, which is actually quite good.
The caveat is that the omega-3 this food contains is alpha-linolenic acid (ALA), not EPA or DHA. Most omega-3 experts will contend that in the most perfect of conditions conversion of ALA to DHA is at best 5%. Again, the women this blog serves seem to need a much higher level of DHA than average for a variety of reasons. We find that they seem to do best on 1000 mg DHA daily, the level recommended by Dr. Artemis Simopolous for treating depression. Calculated out, if you are depending on chia seed to get all of your omega-3 fatty acids, from ALA through EPA and DHA, you're going to need to consume about 115 grams of chia seeds per day. Just be forewarned.
Bottom line, I actually think chia is a healthy food--as part of a varied diet. I especially think that for vegans reading this blog it can be a great addition to your diet. However, I do not believe in superfoods. There seems to be a trend toward wanting to find one perfect food that has it all. I have yet to find it. It's understandable when we're surrounded by a lot of confusing information and we live in a culture where over 10,000 new products hit the grocery shelves each year (I saw half of them in Anaheim last month and it was overwhelming!) that we'd want to have just a few foods and a small nutritional comfort zone. Unfortunately that is not really how human nutrition works.
This is an especially important philosophy to stick to on this blog, given the fact that we're learning that a very high percentage of the women we're helping have some kind of history of"veganism gone wrong"…in other words, overzealous veganism with a focus on eliminating foods rather than on learning how to eat to be nutritionally complete with no animal products on the menu. We discourage fanaticism and encourage food curiosity and variety!
We were designed to be omnivores and to eat a variety of foods from a variety of sources. I encourage you, rather than arguing for why you should narrow your choices down to feel more comfortable around food, to learn to negotiate a wider variety of foods you are willing to include in your diet.

Last night I settled in to watch the evening news, in time to see an ad for Country Crock's Omega 3 Plus brand margarine. With my reputation as somewhat of an"omega 3 queen," I figured I'd better pay attention. And by the time the ad was over, I knew I had today's post.
This label is a perfect example of why consumers are confused, and why they can have a hard time achieving the benefits of good nutritional choices.
First, the good news.
The margarine has no trans fats, because it contains no hydrogenated or partially hydrogenated oils. For fertility, this is a huge plus--with as little as 2% of your total calories per day coming from trans fats (about 2/3 tsp for the average woman), fertility can drop by as much as 73%.
Secondly, one serving provides 500 mg of omega-3's in the form of ALA.
Now for the confusing and potentially detrimental news.
When the professionals on this blog talk about what we're doing to enhance fertility and reduce inflammation, and we refer to omega-3's, we are primarily referring to EPA and DHA, the omega-3's that, except for omega-3 eggs and foods supplemented with algal DHA, contain either fish or fish oil. (Menhaden oil, which is what is found in Smart Balance Omega 3 Margarine, is a type of fish oil.)
Any other type of omega-3 is likely to be ALA. This type of omega-3 is found in canola oil, and flaxseed oil, among other things. In this margarine, the ALA source is canola oil.
But there is no fish oil or marine algae to provide a similar nutritional feature.
There are some things that flax and canola can do, and there are some that flax and canola simply cannot do.
Many people, nutritionists included, operate on the assumption that since the omega-3 found in canola and flax can be converted into EPA and DHA, that you can get enough of the latter two without having to eat fish. Most respected omega-3 chemists will tell you this is highly unlikely.
On a good day, when your diet is as perfect as it can possibly be (which, even in the case of the person writing this post is never), only about 2-3% of your flax and canola can be converted into the other omega-3's.
Bottom line, it's pretty non-negotiable, you are highly unlikely to get the amount of omega-3's your body needs, especially if you are trying to conceive, if you are assuming you can do it without fish.
Secondly, the primary oil in the margarine appears to be liquid soybean oil. Remember the rule about"S" and"C" oils? Soybean is one of those"S" oils with a tendency to be pro-inflammatory. It was impossible to tell from the label what the ratio of soybean to canola oil was, and I would suspect that it was higher than you're going to want if you're trying to choose fertility-friendly foods.
I immediately became suspicious about this Country Crock product when I went to the website and nowhere, I mean absolutely nowhere, could I find a plainly stated ingredient list. Sure, there's a label to look at, but it's strategically posted in a way that all the nutritional information is there except for the ingredients. Hmmmm…
…so I went to the FAQ section. Couldn't find it there either. I found a lot of long-winded explanations of trans-fat labeling, and that was my second red flag.
Since I had to go to the grocery store anyway, I stopped in and looked at the label. Here, for the benefit of the rest of the people on the Internet, is the list of ingredients from the side of the container of this product:
For more information on healthy fats, go to http://www.zingbars.com/science-of-zing.html, where my Zing Bar friends describe why they did--and didn't--include certain fats in their new product.
Any fat that is going to be solid at room temperature is going to have to have some saturated fat in its formula. Otherwise, it would melt. So even though the total saturated fat content is low, the type of fat being used to provide the solid quality is not one you want to get much of in your diet.
I'm not really a butter or margarine person so giving those up was not an issue for me. But I did start my career in the Chicago area, and I remember how people used to look at me like I was purple-polka-dotted if I even hinted that dairy intake might need to be adjusted. So I know it's an issue for some of you.
Bottom line--if you choose to use the product, do so only once in awhile and sparingly. I'd rather see people use olive oil-based dipping sauces for breads and cook with either canola or olive oil.
If you're interested in learning more, the authors of the study below also wrote a recently released book in plain English entitled, The Fertility Diet. I'd check it out.
Chavarro JE, Rich-Edwards JW, Rosner BA, Willett WC. Diet and lifestyle in the prevention of ovulatory disorder infertility. Obstet Gynecol. 2007 Nov;110(5):1050-8.
I just received an email from a client who noticed that every time she added flaxseed oil to her diet, she started to wheeze. We checked online, and sure enough, some people can be allergic to flaxseed. Here are some of the common symptoms of flaxseed allergy.
For anyone who is trying to increase their omega-3's, this can pose a challenge, since the vast majority of foods in the grocery store labeled as omega-3 supplemented contain flaxseed as the omega-3 source. If it turns out you are a flax-allergic person, be extra sure you read those labels!
ALA, the primary omega-3 in flaxseed oil, is not a substitute for fish oil; it has completely different and essential functions. A good way to think of it is that EPA and DHA from fish oil provide the"meat" of the structure of your brain and nerve cells, while ALA acts kind of like"rustproofing", keeping all that DHA and EPA in place that you worked so hard to get in the diet. They both need each other present in order for maximum effectiveness.
Here are some ideas for getting more omega-3's in the diet.
1. Other foods containing ALA include
Broccoli Brussels sprouts Cabbage Canola oil Edamame Kale Parsley Pecans Pumpkin seeds Spinach Spring greens Tempeh Tofu
One reason I have not included walnuts, which are typically the first vegetarian food recommended to increase omega-3 intake, is that the omega-6 content is so high that it is mathematically impossible to improve an omega-6 to omega-3 ratio when using them. I love walnuts and think they have some great nutritional benefits for PCOS, but in the rare and special case of a flaxseed allergy, it may not be a food that you would want to eat in large quantities. (I'm working on a pro-walnut post for a later date for you curious types!) Here are some practical ways to incorporate the foods above into your diet.
1. Know your nuts! The nuts with (a) the best omega-3 levels and (2) the best overall ratios of healthy to unhealthy fats include: macadamia, hazelnut, pecan, pine, and pistachio. Those are the nuts you should be using with the most frequency in your snacking and cooking. If you like nut-encrusted fish and pesto sauce…you're in luck! You can also throw nuts in your coffee grinder to make nut powders, which can be added to waffles, pancakes, baked goods, smoothies, and salad dressings. They'll give your creations a little bit of a gourmet twist!
2. Use shredded cabbage in your tacos instead of shredded lettuce. That's how they do it in Mexico…and it's the perfect topping for a fish taco!
3. Get in the habit of throwing a handful of dark greens--kale, spinach, parsley--into your smoothies. You won't even taste them.
4. Pumpkin seeds, like nuts, are easily added to trail mix, thrown on salads, soups, and hot cereals, and ground to include in your encrustings.
5. Cook with canola oil.
6. I've included the three types of soybean that are not tough on thyroid--edamame, tofu, and tempeh. Edamame is a fun snack when popped out of the shell, tofu and tempeh can be the basis for a meatless meal.
7. If you like pesto, you may want to try chimichurri, another parsley-based sauce that I call"South American pesto". It is wonderful on grilled meats and easy to make! I've seen ready made varieties in the grocery store.
8. Be extra careful about omega-6 fatty acids. The less of those in your diet, the less omega-3 you will need to counter their inflammatory influence. For review, except for canola, which is ok, minimize your use of oils beginning with the letters"s" and"c"…safflower, sunflower, soybean, corn, cottonseed. (The reason soy as a food is ok while soybean oil is not, is because the ratio of omega-6 jumps up when you extract and use only the fat and do not buffer it with the meat of the soybean.)
Here are a couple of recipes for you, one for chimicurri sauce, and one for a tasty squash/kale/whole wheat lasagna I tested out this week.
It just takes a little creative thinking to find ways around a flaxseed allergy. Hopefully some of the suggesstions I'm providing turn out to be favorites in your home!
Spinach Kale Whole Wheat Lasagna (from Sunset Magazine, February 2008)
Note: I couldn't find whole wheat lasagna noodles in my store so I bought whole wheat egg noodles and layered them with the other ingredients to make a casserole. It was great! Prep and Cook Time: about 2 hours. Notes: You can assemble and chill the lasagna a day ahead, but add 10 to 15 minutes to the baking time. You can also freeze the lasagna, wrapped well in plastic wrap, for up to 1 month and bake it frozen (add 1 1/4 hours to the oven time).
Yield Makes 8 servings
Ingredients 4 tablespoons olive oil, divided 1 medium red onion, peeled and sliced 3 peeled garlic cloves (1 minced, 2 left whole) 2 cans (14 oz. each) crushed tomatoes 1 teaspoon dried oregano About 1 tsp. each salt and freshly ground black pepper, divided 6 cups (about 2 lbs.) butternut squash, peeled and cut into 1/2-in. cubes 1/2 tsp. dried thyme 1 pound Lacinato kale (often sold as dinosaur or Tuscan kale) 9 whole-wheat lasagna noodles (about 8 oz.) (Often, whole wheat pastas are made with flax…be sure to read your labels!)1 container (15 oz.) part-skim-milk ricotta cheese 1/8 teaspoon ground nutmeg 2 cups shredded mozzarella cheese, divided
Preparation 1. Preheat oven to 400°. Heat 2 tbsp. olive oil in a 2- to 3-qt. pot over medium heat. Add onion and minced garlic; cook, stirring occasionally, until onion is soft and translucent, 5 minutes. Add tomatoes, oregano, and 1/2 tsp. each salt and pepper. Reduce heat and simmer until thick and flavors are combined, about 30 minutes. Set aside.
2. While sauce is cooking, in a 12- by 15-in. baking pan, sprinkle squash with thyme, remaining olive oil, and salt and pepper to taste. Add garlic cloves and toss squash mixture to coat with oil. Bake until soft, 10 to 15 minutes. Meanwhile, bring 3 qts. salted water to a boil in a large pot.
3. Reduce oven temperature to 350°. Transfer squash and garlic to a food processor and purée until smooth.
4. Tear kale leaves from center ribs and discard ribs. Boil leaves until soft, 5 to 8 minutes. Drain; let cool. Squeeze out as much water as possible and chop finely.
5. In the same pot, bring another 3 qts. salted water to a boil. Add noodles and cook until tender to the bite, about 10 minutes. Drain; rinse with cold water.
6. In a bowl, mix ricotta, nutmeg, 1 cup mozzarella, and remaining 1/2 tsp. each salt and pepper.
7. Coat the bottom of a 9- by 13-in. pan with 1/3 of tomato sauce (about 1 1/2 cups). Lay 3 noodles in a single layer over sauce. Top noodles with squash, spreading evenly. Sprinkle 1/2 of kale evenly over squash. Arrange 3 more noodles on kale and top with ricotta, spreading evenly. Top with remaining kale and noodles. Cover noodles with remaining tomato sauce and sprinkle with remaining 1 cup mozzarella.
8. Bake lasagna until juices are bubbling and cheese is melted, about 30 minutes. Let stand 10 minutes before slicing.

I can tell by looking at this blog's visitation statistics that a very high percentage of its visitors are looking for help with an immediate problem that has"hit them where it hurts", so to speak. You may have acne. Or want a child. Or be looking for a successful weight loss plan.
The fact is, however, that sitting in my seat, it is equally important to offer insight and solutions for those problems as it is to educate about the big picture.
The fact is, 10% of women with PCOS will be diabetic by age 40.
The fact is, PCOS increases your risk of heart disease and high blood pressure.
And…since diabetes is increasingly being associated with Alzheimer's disease, the fact is, you may end up being at risk for that as well if you're on this blog looking for help with your acne.
Fortunately, you don't have to do one thing for your fertility, another for your acne, and another to prevent Alzheimer's. All the suggestions you see here work to help all organ systems function better.
And the fact is, there is a whole lot you can do to decrease your risk of having any of the problems mentioned above.
The fact is, you can't decrease your risk if you don't take action. That part of the solution is totally in your control.
In this particular study, the alpha-linolenic acid (ALA)concentrations in fat tissue were evaluated in 1819 people. (ALA is a type of omega-3 fatty acid found in flaxseed, flaxseed oil, soybeans, canola oil, and nuts, to name a few.)
Individuals with higher levels of ALA had a lower risk of heart attack.
The fact is…if you cook more often with canola oil, eat more nuts, put some edamame on your next salad, and/or add some ground flaxseed to your next bowl of oatmeal, you just might experience the same benefits as the people in this study.
If it can't hurt and it might help, there doesn't seem to be a reason not to try at least one of those things!

Many of the women I work with are vegan vegetarians. Which means when it comes to increasing omega-3 intake, they tend to want to go heavy on flax, hoping it will make up for not eating fish. It simply doesn't work this way…in ways that are very important to PCOS.
When different groups of rats are given ALA (the primary omega-3 in flax), EPA and DHA (the primary omega-3's in fish oil), EPA and DHA lowered glucose and insulin levels about 35-38% greater than did ALA. Insulin sensitivy improved by 60% in the fish oil groups compared to the ALA groups.
Bottom line, if you really, really want to get better, and you're not currently eating fish, or using a fish or marine algae supplement, you may want to seriously consider adding one of those to what you're doing. It's pretty non-negotiable, we need DHA and EPA to properly function as human beings.

The Truth About Canola Oil
By Christine E. Marquette
Have you read somewhere on the internet, or better yet, gotten an email from a friend, that says canola oil is not healthy, and worse, is down right dangerous? I’ve gotten these emails myself, and have seen some of the websites disparaging canola oil. In an effort to set the record straight, I first looked up the nutritional profile of canola oil on the USDA’s Nutrient Data Library, and compared it to Olive Oil. Keep in mind that virtually every website that provides nutrient analysis information gets their data from this website.
What I found was that canola oil contains about 1 gram (g) of saturated fat, 8.86 g of monounsaturated fat, and 3.94 total grams of polyunsaturated fat per tablespoon.1 The polyunsaturated fat includes 1.28 g of alpha-linolenic acid (ALA omega 3) and 2.6 g of omega 6 fatty acids. Olive oil contains 1.86 g of saturated fat, 9.85 g of monounsaturated fat, and 1.42 total g of polyunsaturated fat per tablespoon.1 The total polyunsaturated fat includes 1.32 g of linoleic fat and 0.103 g of linolenic fat; it does not contain any ALA omega 3 fatty acids (or EPA or DHA omega 3). As you can see, canola oil actually has more omega 3 fatty acids in the form of alpha-linolenic acid than olive oil. This is one positive regarding canola oil.
But a lot of the fear mongers will say that even if this is true, canola oil has high levels of erucic acid, which is dangerous. Originally canola oil did come from the rapeseed plant, which is a member of the mustard family, and did have high levels of erucic acid, but newer “breeds” of rapeseed plant used to make canola oil now have very low levels of erucic acid.2 I did not find any studies showing that the level of erucic acid in canola today causes any health problems.
Others will go on to say that even if the erucic acids are low, it is still bad for you because the polyunsaturated fats in it are unstable and can become inflammatory. If canola oil was truly inflammatory, the various clinical studies on canola oil would have shown it. Instead, there have been several studies in humans showing canola oil “produces hypolipidemic, anti-inflammatory, and antithrombotic effects,” which means it is indeed heart healthy. 3, 4
I did not find a single scientific study that showed any detrimental effects on humans from conventional canola oil. It is true that 80% of canola oil in North American is genetically modified to make it resistant to herbicides, which has not had an effect on its fatty acid profile. 5 There have also been some websites claiming that it has been banned in Europe. I have not found this to be the case either. It is true that in Europe there is a ban on genetically modified organisms (GMOs), so canola oil produced there comes from non-GMO rapeseed plants and is called “oil seed rape” rather than canola oil, but as far as its nutrient profile (percentage of omega 3s, monounsaturated fats, etc.) it is the same as conventional canola oil produced in North America.6
I can understand the fear in using GMOs, as some studies have shown certain foods that have undergone this process have gone on to cause problems in rats. The exact effect in humans is still under investigation. To allay that fear, I would suggest sticking with organic, non-GMO canola oil. Also make sure that no matter what type of oil you choose, if it is unrefined, avoid cooking at temperatures higher than about 355 F as high heat can cause chemicals to be released from unrefined oils that may increase the risk of cancer.7,8

POSITIVE: To put that into perspective, a tablespoon of hemp seed has about the same amount of fat as a teaspoon of butter or oil, plus slightly less protein than an ounce of meat. So as far as fat choices, it's going to give you more nutritional bang for your buck than a pure fat source. That protein is also a complete protein, too!
WARNING: Beware of those calories, though! Someone who commented on the Livestrong.com website where I got this information shared that he puts 3 tablespoons of hemp seeds on his cereal every morning. That is 240 calories, which if not removed from elsewhere in the diet, is the equivalent, over a year, of 25 pounds' worth of calories. If you ADD hemp to your diet, be sure you've accounted for it by REMOVING less calorically dense/nutritious food choices.
POSITIVE: With respect to fatty acid profile, the omega-6 to omega-3 ratio of hemp averages 3:1. This is favorable, as it is lower than the recommended total dietary ratio of 4:1.
WARNING: As hemp is a vegetarian source of omega-3, it provides ALA. It does not contain EPA or DHA, which are primarily found in seafood. Some of the ALA found in hemp will be converted into EPA and DHA, but not in the quantities we have found to be of therapeutic value for PCOS. If you want to use hemp in your diet, it is certainly beneficial, but it does not replace the need for the other omega-3's.
POSITIVE: Hemp contains gamma-linoleic acid (GLA), which can be helpful for some skin conditions, including atopic dermatitis.
WARNING: GLA tends to work best when it is not overwhelmed with omega-6 fatty acids. In other words, if you have a skin condition, and you want to try GLA as a remedy, you are most likely to achieve good results if you cut back on your total omega-6 fatty acid intake (safflower, sunflower, soybean, sesame, corn, and cottonseed oil).
You could say the bottom line with hemp, as with any other food, is that if it is used judiciously and respectfully and not layered onto an unhealthy diet that needs some tuning up, it can be a tool toward better hormone balance.
But it is not a miracle food that will allow you to continue with unhealthy dietary indiscretions without consequence.
For those who are concerned about the THC content of hemp: in order to ingest enough industrial hemp to get 'a buzz', you would have to consume the the equivalent of 2-3 doses of a high-fiber laxative. Thanks to the North American Industrial Hemp Council for that little tidbit!
For starters, here is a recipe for hemp pancakes. As you can see, the oil has been removed and replaced with hemp seed. That is the way hemp should be used; as a fat alternative, not as an additional fat. It could probably be used in many recipes where you are using ground flax seed, with similar results.
Here are some sample hemp food products available at amazon.com
For more information about the history, politics, and nutritional analysis of hemp, beyond the direct pertinence of hemp to PCOS, try this article on Dr. Bronner's website.
Most of you have some type of sleep disorder…and that can mess with your insulin and melatonin levels. You've already been told, here, and many, many times, elsewhere, that you need to get more omega-3's in your diet.
Did you know, chia seeds are one of the highest omega-3 foods around? One ounce of chia seeds has about 5000 mg of ALA, the vegetarian omega-3. That is more than twice what you need in a day!
Interestingly, chia seeds are high in tryptophan and often have a side effect of drowsiness, so if you're one of that majority of women with PCOS who have trouble with sleep, here's a potential idea for a non-pharmaceutical answer.
Dr. Oz (he's not my usual reference but this seemed practical) recommends taking chia seeds about 3 hours before bedtime. You can simply stir them into a glass of water and drink them, or you can sprinkle them onto yogurt, or into smoothies.
One of my friends of Mexican descent recently shared a recipe from the blog No Meat Athlete for something called pinole, a chia/cornmeal cake that has been made for centuries by the Tarahumara Indians of Mexico. They're the ones famous for running. I tried the recipe out last week. Instead of adding sugar, I juiced a nectarine and stirred it in. It was interesting, and I intend to experiment more with the recipe to make it more user-friendy. In its current form it's probably more something a total nutrition junkie would eat, not something irresistible to the average American palate. Here's the link if you want to try it out for yourself. If you make revisions that you like please share them!
We've been getting some inquiries about chia, given our love of omega-3's. Here are some basic facts that can help you decide for yourself if chia will work with your PCOS plan.
Chia (salvia hispanica), is a seed that originates from Southern Mexico and Guatemala. Way back when, it was a major staple food of the Aztec Indians. Other names you may see this seed sold under include: Cheela Brand, Sachia, Anutra, Chia Sage, Salba, Tresalbio, Purisalv, and Mila.
Nutritionally, chia is 20% protein, 34% oil, and 25% fiber. It is not a complete protein, as it lacks the essential amino acid taurine. Its fat is primarily ALA, the same type of fat found in flaxseed. Its omega-6 to omega-3 ratio is about 3 to 1, which is nice.
Two benefits to chia are that it does not need to be ground like flax does in order to gain its health benefits, and it does not go rancid as easily as flax. One major disadvantage is its cost. It's definitely not for those on a budget.
Especially, if you are Hispanic or living in the Southwest, this is a great source of omega-3's that is more locally available than flaxseed.
Be aware, however, that claims about its health benefits can be exaggerated.
1. Chia is not a complete omega-3. In other words, it can be used as a substitute for flaxseed oil, but not for fish oil. You still need a DHA source.
2. While they do have their health benefits, I could not find any peer-reviewed studies to support the hype that chia seeds have been given as an athletic performance superfood.
3. I did find one study, performed on chickens, (below) reporting that chia supplementation positively changed their fat content. However, chia was not compared to any other supplements or to a diet with a similar fatty acid composition from other grains. So it is impossible to assert that it was specifically something in the chia that had the effect.
Bottom line, it certainly won't hurt you to include chia in your diet, but just because you do, it does not give you license to eliminate other healthy eating. They can enhance, but they won't replace the benefits of the many good things you're already doing.
R Ayerza, W Coates, and M Lauria Chia seed (Salvia hispanica L.) as an omega-3 fatty acid source for broilers: influence on fatty acid composition, cholesterol and fat content of white and dark meats, growth performance, and sensory characteristics. Poultry Science, Vol 81, Issue 6, 826-837.
Fatty liver is a common problem in women with PCOS. In this study, EPA, an omega-3 fatty acid and a fish oil, was shown to improve the symptoms of nonalcoholic steatohepatitis (fatty liver). EPA is the fish oil that you cannot get when you rely on vegan sources of omega-3's--it's not in flax, and it's not in marine algae. Some research shows that when you've eaten enough marine algae to completely saturate your tissues, what's left can be used to make EPA, but it's not the way of getting it that the body prefers.
This is important to understand, because the vast majority of foods that are labeled as supplemented with omega-3 fatty acids either contain ALA (primarily in the form of flax) or DHA (primarily from marine algae).
The other advantage to eating fish is, that if you've put a fillet on your plate, you've likely removed another (fattier) kind of protein. That's the positive double whammy you get in seafood choices.
In my training I was always encouraged to develop good negotiation skills. In other words, if a client didn't like a certain food, to have a few other options up my sleeve that would provide equivalent nutritional value. Only when I got into omega-3 chemistry, inflammation, and PCOS, did I realize that in this one crucial area, I would have to dig my heels in and advocate that this essential nutrient was simply non-negotiable: if you don't eat fish, you miss out on total health.
Over the weekend I had an animated discussion with another dietitian who was adamant that her clients (mainly with eating disorders) simply were not going to accept this. I told her they simply would not achieve total health…and possibly total recovery. I got some resistance, but hopefully at some point this colleague will come to understand that we're here to guide our clients where they have the potential to go. We're not here to tell them what they want to hear, with the hopes that somehow health will just magically appear.

I'm all for local eating. But another endeavor I enjoy is helping other cultures find worthwhile products to produce that encourage preservation of the rainforest and farming of products other than coca. So I was excited to see the country of Peru have such a beautiful and informational pavilion at Expo West.
We all know about quinoa and I've written about purple corn…here are some other foods you might be seeing more of that could be fun to try!
Maca Most of us think of maca as a supplement to enhance sexual prowess. It's actually been studied in the laboratory and been found to enhance libido and semen quality. It may also help alleviate sexual dysfunction related to antidepressant use. It may also help reduce enlarged prostate glands.
That being said, Americans have a really bad habit of taking something they think is"good", grinding it up, concentrating it, and using it in larger quantities than would be possible in nature. In this case, there is some thought that excessive maca consumption may negatively affect thyroid function. In addition, there are several varieties of maca, and only the red was found to have significant hormonal effect. Labeling on supplements may not contain this information and you may be wasting your money.
Bottom line, if you see it on a restaurant menu or a fun international market, take it home and cook it like a turnip! Be careful, however, about the supplement version.
Amaranth Gluten-free enthusiasts love this grain, but like quinoa, it's not actually a grain…it's a seed. It can be toasted and eaten like popcorn, or cooked like a grain. Here is more information on how to use amaranth in your kitchen. In other parts of the world, such as Asia and Africa, amaranth leaves and roots are also culinary specialties.
Regular consumption of amaranth seed may help regulate hypertension and cholesterol, and the leaves and roots are very high in vitamins and minerals, including calcium, iron, magnesium, phosphorous, potassium, zinc, copper, and manganese.
Both Bob's Red Mill and Arrowhead Mills sell amaranth flour, but if you can't find it in your store, here are amaranth options on amazon.com.
Aguaymanto This fruit is related to one of my local favorites, the tomatillo (you can see the similar husks in the photo). It is currently being researched for its potential as an antioxidant source, and it has been found to contain melatonin.
Locals like to use it in jams, syrups, and pastries, but it is also seen in fruit salads and salsas.
Lucuma, or eggfruit, if you Google it, will pop up quite frequently as the next big superfood, and ground powders are available online. (As with maca, I am not providing links, as I am not telling you about these foods to encourage a superfood or supplement mentality.) This fruit tree can grow in warmer US climates such as Florida or Arizona. It's a Peruvian favorite, as illustrated by the blog Peru Food. It is described as tasting a little bit like maple syrup ice cream.
It is a favorite of raw food enthusiasts. They promote it as low-glycemic, though I was not able to find the actual scientific reference for it in my search; most references circle back to the same video. If anyone out there can direct me to that, I'm happy to post for everyone.
Nutritionally, lucuma is high in fiber, iron, and as you might guess from its beautiful color, beta carotene.
Sacha Inchi, or the Peruvian peanut, comes from the rainforest. I actually tried this at Expo West; it was prepared like corn nuts and there was also a version coated with fair-trade chocolate (isn't that the best way to get Americans to try anything new and different?) It's pretty high protein, and it contains ALA, the vegan omega-3 fatty acid. (With respect to the omega-3's it's an option to flaxseed.) In Peru, its oil is used for cooking so I imagine some day it will show up in US markets as well.
Again, American marketing reps are trying to capitalize on the superfood craze when selling this food. It's fine to eat, and its nutritional value is nice, but no need to abandon everything else you're doing for it. Try it when you can, enjoy it when you find it, and know it fits well into a hormone-friendly lifestyle.
One of the reasons I put this blog post together is to illustrate why closing out food choices can deny you some food fun, not to mention nutrition! If you're locked into a top ten list of foods, you may miss some great culinary experiences…that can be healthy as well! Sometimes when you're focused on"fixing" a disease it can take the fun out of food. The more enjoyable it is, the more likely it is you'll have a healthy relationship with it. Every culture has its gems, even if they're not salmon, blueberries, and broccoli!
I admit, I had a personal reason for writing this blog post. My Peruvian friend Denise has told me she wants to share her favorite local Peruvian restaurant with me sometime soon. I wanted to be sure I knew what I would be seeing when I looked at the menu. Now that I've done my homework, I'm hungry and looking forward to what the menu has in store.

This is a comment to an older post that I did not want anyone to miss. Thank you so much, Eve!
Metametrix Clinical Laboratory does offer testing of these fatty acids in a few different profiles. One that is quite popular due to the ease of specimen collection is the Fatty Acid Bloodspot Profile. It requires only a finger stick, and will measure levels of the Omega-3 fatty acids ALA, EPA, and DHA. It reports several Omega-6 fatty acids including arachidonic acid, the pro-inflammatory fatty acid. Tran-fatty acids are measured, giving important insight into dietary trans-fat intake, something that has gained notoriety in the news. And finally, the ratio of Omega-3 to Omega-6 is reported which is a useful tool to monitor your dose of fish oils--the importance of which hormonewoman was mentioning above.
For a site dedicated to PCOS, it was nice to see a discussion on fatty acids. You've probably seen the recent publication by Liepa GU, Sengupta A, Karsies D. in Nutrition in Clinical Practice Feb 2008: Polycystic ovary syndrome (PCOS) and other androgen excess-related conditions: can changes in dietary intake make a difference? And indeed they do recommend omega-3 fatty acids to improve patient outcomes. The question always boils down to"How much?"
Thank you hormonewoman for taking the time to discuss the fish oil facts.
