Aaahhh eggs, the misunderstood member of the nutrition family. Poor guys…when I graduated from college, in the height of the low cholesterol-low fat craze, we were indoctrinated to teach that"egg" was just another word for poison.
My how things have changed!
A couple of months ago I heard Dr. Susan Kleiner (www.goodmooddiet.com) speak at a conference. She shared that not once has there been a research study demonstrating that when you take eggs out of the diet, that this dietary change reduces cholesterol. As well, there has been research demonstrating that adding eggs (plus yolks) to the diet does NOT raise cholesterol. All those yolks I threw down the drain all those years…for nothing.
I figured I'd better find some hard research to back THAT one up, so here's a quick list of interesting titles I found in PubMed: Dietary cholesterol from eggs increases plasma HDL cholesterol in overweight men consuming a carbohydrate-restricted diet Egg yolk improves lipid profile, lipid peroxidation and retinal abnormalities in a murine model of genetic hypercholesterolemia. There are many more, but here I just wanted to make my point. Egg yolks are not the ugly stepchild of the protein family anymore.
In fact, there are some great nutrients to be found in eggs.
1. Lutein and xeanthin are two carotenoid compounds that can help maintain visual health. One group of researchers reported that 6 eggs per week can help increase lutein and xeanthin levels in the macula, the part of the eye that degenerates in this country's leading cause of blindness, macular degeneration.
2. Eggs contain choline. This compound is very important for brain function. Choline is the building block for acetylcholine, the neurotransmitter involved in memory, and the one that many Alzheimer's medications seek to increase.
This compound is exceedingly hard to get in the diet. In fact, about the only two places you can find it, are egg yolks, and soy. (Well, also in cooked chicken, beef, veal, and turkey livers, but I didn't think that would have any of you running for your grocery lists so it goes in parentheses.)
If you've got PCOS, you've probably been told to avoid soy. So that leaves egg yolks for getting this very important memory booster.
3. If you hate fish but you need to increase your fish-based omega-3 intake, omega-3 eggs are a very cost-effective option. If you struggle to get enough vegetables in your diet, omelets and frittatas are great ways to get them in. Just be sure you use olive oil when you cook them.
I thought it might be timely to include eggs on this blog, because as food prices rise, they can certainly be much more cost-effective than salmon, as well as other proteins that are now taxing your grocery bill.

Not long ago, I stopped into Planet Raw, in Santa Monica. It's a very popular hangout for raw foodists, so I wanted to see what the buzz was about. I actually enjoyed perusing the shelves, and they did have some fun things to buy for the more adventurous cook. I'll probably eat there from time to time, as it's a stone's throw away from my office.
However…I had a most disturbing conversation with one of the employees. When she learned that I was a dietitian, she commented,"Cool, maybe you can help then. We're having trouble finding protein sources. Do you have any ideas?"
So I mentioned Growing Naturals, the rice protein powder that I wrote up last week.
"Oh, we don't do rice."
When I asked why, she responded by explaining that Planet Raw's owner"doesn't do rice".
So I suggested pea protein.
"Oh, we don't do peas, either."
When I asked why, she responded by explaining that Planet Raw's owner"doesn't do peas".
I could see I wasn't going to get anywhere because I was in a food religion debate, not an evidence-based scientific discussion, so I politely guided the conversation to its end.
I later went to the website (which you can Google for yourself, I won't provide free advertising for this place through linking), and could find absolutely nothing explaining this philosophy. I saw plenty of advertising for expensive certifications as raw chefs, and courses for raw foodists…which, in essence, kind of seemed like me to be expensive courses on how to promote malnutrition.
I do my best to be positive and inspiring rather than confrontational on this blog, but sometimes I get pushed past my limit of tolerance. This philosophy, especially for women with PCOS who need a decent amount of protein in their diet to reduce the influence of insulin resistance, is simply dangerous.
Of course, a diet that is heavy on the raw, is perfectly fine. It means you're eating plenty of fruits, vegetables, nuts…all great sources of vitamins, minerals, antioxidants, and fiber. But a completely raw diet needs to be taken on with a lot of thought, not be a source of pride with regard to how many foods you can find an excuse not to eat. Here is why.
At the same time raw food diets have been studied and found to have benefit, they have also been associated with many problems women with PCOS already have.
lower bone density, amenorrhea and underweightness in women, dental erosion with a raw vegan diet,
elevated plasma homocysteine and low serum HDL cholesterol" and vitamin B12 deficiency.
Bottom line? Enjoy your occasional lunch at Planet Raw, and buy their coconut flour. But don't depend on them for advice when it comes to how to eat this diet in a way that allows you to reduce the influence PCOS has on your life.
For the record, I am NOT anti-raw. I am anti-malnutrition, and anti-inflammation. Be sure you know the difference if you choose to pursue a raw foodist lifestyle/food religion.

I was recently graciously shipped a jar of Tropical Traditions Gold Label Standard Virgin coconut oil for review. First of all, thank you to Tropical Traditions for their generosity! I use coconut oil twice a day on my skin and I love the noticeable difference it makes. I'm also learning to cook with it, and am happy to have this to work with.
This is a long, drawn out post. I'm putting my conclusion at the very beginning so you can decide if you want to sit through the rest:
I love coconut oil, I use it myself, both in cooking and on my skin. I love this particular brand and product, and it's clear that the company is very proud of the attention they devote to quality and sustainable practices. If you choose to incorporate coconut oil into your cooking, and I hope that you do, please consider supporting a company that works so hard on behalf of integrity.
My intention is to encourage more people to use coconut oil than currently do. It wasn't long ago that we discouraged coconut oil consumption and I still encounter people who think it's unhealthy. I'd also like to encourage those who may be creating problems with excessive use, to understand why that may not be a good choice.
My only reservation is that there is somewhat of a health halo hanging over coconut oil that encourages its use in quantities that potentially do not support improved health.
I'll be addressing those issues in this post. A little bit of feedback on the coconut oil information I found on the website.
In the FAQ section, there is no peer-reviewed reference provided to support the following statement:
The benefits of coconut oil are mainly from the nutrient value of medium chain fatty acids (MCFAs). The best comparison in nature as to the percentage of MCFAs being consumed in a diet is human breast milk. To equal the amount of MCFAs a nursing infant would receive in one day, an adult would need to consume about 3.5 tablespoons of coconut oil a day according to researchers.
1. With regards to fat, what an infant needs, nutritionally, is far different from what an adult needs.
For example, nutrition experts recommend 2% milk for children up to to years of age, then a drop to 1% or skim. The reason for this recommendation is that the extra fat is needed during the first 2 years of life to help fuel the rapid growth occurring during that time. As growth and development slow, so do needs for dietary fat.
Arachidonic acid (ARA) is an essential fatty acid for infants. The only place they can get it is milk, so if an infant is formula fed, ARA needs to be added to that formula. When that infant is weaned, however, and can get this fatty acid elsewhere, it no longer needs to be added to the diet.
It simply has not been proven that nutritional needs for infants are the same as nutritional needs for adults. Or that what you would feed an infant is even healthy for an adult. So I'm not entirely convinced that the extrapolation from an infant's saturated fat intake in breast milk, to a recommendation for adults of 3.5 tablespoons per day is a logical or healthy leap. (I am happy to adjust my stance if peer-reviewed research supporting the higher level becomes available. Our readers are in large part pursuing fertility and possibly in the midst of infertility treatment. I owe it to these high-risk situations to lean toward the skeptical and conservative. I don't want to heap more expense, stress, and/or disappointment on women who take our advice so seriously.)
Fat is fat, no matter where it comes from, it still contains calories, and the recommendations are still to keep saturated fat intake to about 10% of total calories. Regardless of the source of the saturated fat.
I did a long blog post calculating dietary amounts for different calorie levels that this translates to not too long ago if you want more specifics. I do think that when possible, saturated fat from coconut oil is better than saturated fat from meat, so the focus needs to be learning how to make that switch. (See the recipes I posted below.)
2. In moderate quantities, coconut oil can definitely be beneficial. A 2009 Brazilian study providing 1 tbsp per day of coconut oil to a group of women with abdominal obesity found that compared to 1 tbsp of soybean oil, the coconut oil group had higher HDL, a lower LDL/HDL ratio, and a reduced waist circumference. It cannot be determined from this study design if the change was due to the absence of soybean oil, the presence of coconut oil, or a little of both, but it does illustrate that when used in moderation, coconut oil can be part of a hormone-friendly eating program.
3. What IS showing up in the literature is that too much coconut oil can be metabolically deleterious. Individuals at risk for diabetes (and if you have PCOS that means you) need to use coconut oil with care. One recent study in particular (done with calves) compared coconut oil to a non-medium-chain triglyceride (MCT) diet as well as to another MCT, caprylate oil. The coconut oil-fed calves weighed pretty much the same at the end of the study, contradicting claims that coconut oil promotes weight loss. In addition, the coconut oil calves had heavier, fattier livers and contained 15% more fat than the livers of the other calves.
Bottom line, used respectfully, coconut oil has many health benefits and I do encourage its use. What I DO discourage, is using this product indiscriminately with the belief that it has any kind of magical quality that counteracts dietary indiscretions or which somehow allows you to ignore other important rules of nutritional balance.
4. I spent a long time on the company's companion website, http://www.freecoconutrecipes.com/ to see how others were using coconut oil in cooking. Most of the recipes were for baked goods and sweets, the use of which, due to the insulin resistance issue the readers of this blog deal with, should be limited. Cakes, cookies, etc., are not nutritionally dense and cannot be eaten in large quantities just because of the oil they were made with.
I did find a great recipe for coconut oil vinaigrette coleslaw, which nicely combines the concept I've been writing about recently, consuming a bit of vinegar before meals, with a nice, moderate use of coconut oil. I would so love to see more savory recipes like this, as it would help the readers inCYST most often works with, to use this oil to their benefit.
I did my best to walk the walk, as well, and asked the members of our Facebook fan page to share any savory recipes they might have using coconut oil. Here are a few provided by culinary school graduate Alyssa Fritts.
Coconut Green Beans Blanch fresh green beans by dumping them in boiling water for about 20-30 seconds. Strain them out and put them in ice water to s top the cooking. Melt a tsp or less of coconut oil in a pan. Add 1/2 clove of garlic and the strained green beans, toss around a few times. Add chopped almonds and salt and pepper to taste.
Coconut Pork Chops Put a little bit of coconut oil in a pan, salt and pepper pork chop with all fat trimmed Brown on both sides. Remove chop, add garlic, and chopped onion. Saute until garlic is fragrant. Add veggie or chicken stock and a LITTLE bit of apple jui ce. Put chop back in and let it reduce down by about half. Remove chop and place on plate. Add a scoop of stone ground mustard, and a sprig of fresh rosemary. Let it thicken. Finish with a swirl of coconut oil to give it the smooth fullness butter would. Pour over your chop.
Miso-Ginger Salmon 1/2 tsp coconut oil 1 clove minced garlic 1/8 in piece peeled ginger in matchsticks 1 tbs chopped onion 1 tsp miso paste 1/4 cup white wine 1/4 cup veggie stock or water 1/4 tsp coconut oil
Melt 1/2 tsp coconut oil in pan. Salt and pepper salmon. Place in pan skin side up. Brown on both sides. Set aside on a plate. If needed as a tiny bit more coconut oil. Add ginger and garlic. Add onion and sautee for a few seconds. Add wine and stock. Add salmon back to pan and cook for about 5 min. Remove salmon and turn heat up to high. Add miso and reduce down until thick. Swirl in a tiny bit (up to 1/4 tsp) of coconut oil and pour over salmon.
What Alyssa is illustrating, beautifully, is that one of the best ways to use coconut oil is to switch out other oils for coconut oil in your regular cooking, being careful with quantities just as you would any other fat. It adds a nice flavor while it helps your metabolism.
If any of you use Tropical Traditions Coconut Oil, and you've developed some savory, hormone-friendly recipes you'd like to share with our friends at Tropical Traditions, I would love if you would do that. I'd like their customers to see just how much potential this oil can have in the kitchen. I'd really love to see this company, which clearly has a heart for wanting to do something good, succeed at that goal. I'm in love with the creativity of inCYST fans, and encourage you all to step up and share it in a way that can have benefit far outside of this blog post.
Bottom line: Used intelligently and respectfully, Tropical Traditions gets a thumbs up. Stay tuned, as tomorrow we're going to announce a giveaway encouraging you to think about and incorporate the concepts presented in this blog post!

Something it is important to remember about PCOS is that infertility is a symptom of a much larger problem. In addressing infertility, if you tackle the core imbalance, you will likely increase your chances of conceiving. If you only address the infertility, without tackling the core imbalance, it will be much harder to conceive. The problems cannot be parsed out and treated as if they are individual. For that reason, if you have PCOS, and you're not trying to conceive, myoinositol may still benefit you. Here is a brand new study out of Italy supporting that. A myoinositol/folic acid supplement was given to 35 women with PCOS for a period of 24 weeks. A second group of women who also had PCOS were also studied, but not given the supplement. Only five of the 35 women receiving the supplement at the end of the supplement were not ovulating. This group as a whole also lost weight, while the women not receiving the supplement trended on the side of weight gain. Cardiac risk factors also improved with the supplement; LDL lowered slightly while HDL increased. It appears as though this supplement has strong relevance for many of the problems related to PCOS that often elude resolution. I'm providing the reference for this study should you wish to show it to your physician and discuss whether this may be a treatment option for you.

If you're looking for pasta alternatives, consider soba noodles. This gluten-free Japanese creation is made with buckwheat, a food with potential multiple health benefits. Buckwheat has repeatedly been shown to improve blood lipids, by lowering blood pressure, total cholesterol, bad cholesterol (LDL), and triglycerides, and raising good cholesterol (HDL). It has also been reported to prevent the development of gallstones
Buckwheat is also a potent cancer fighter. It contains anthocyanin compounds (yes, that stuff that makes blueberries so healthy!), and it has been shown to fight tumor growth in a respectable list of body parts.

Buckwheat is also good for people with insulin resistance. In one study, people who did not regularly consume buckwheat were five times more likely to have hyperglycemia (high blood glucose) than those who did. When it comes to our recent theme of increasing protein and maximizing muscle mass, buckwheat has been found to be a good vegan protein source for accomplishing this goal.
If you have been following my interest in bees and colony collapse disorder (important to PCOS because many hormone-friendly foods are dependent on bees for pollination), eating soba noodles is good for bee health as well. Provided the buckwheat is organic and not laced with pesticide, one acre of the crop supports an entire hive of bees, important in US locations where bees have been found to be declining because of exposure to neonicotinides used on corn. And buckwheat honey is good for you as well; it has a reputation for its antioxidant and antifungal content. You can make a difference! Increasing demand for crops that are healthy for everyone in the ecocycle is a win-win situation.
One note for celiacs: soba is only partially buckwheat. Be sure you read the labels and use a brand like Eden 100% Whole Buckwheat Soba.
The photo above is from a blog post I found on Pinterest. The recipe looked easy and like it was a great noncommittal Americanized way to put a little soba on your plate.

Anyone living out West has had a week of comfort food weather! Here in Phoenix we had as much rain in a week as we normally get in a year. I haven't felt like venturing out, and I want foods that warm me from the inside out.
And that has had me thinking about leeks.
Leeks are the onion's, unfortunately less popular and often forgotten, cousin. I say that because leeks are milder than onions, with a lot of the same health benefits. Many of those benefits are related to PCOS health risks.
Vegetables in the onion/leek/garlic family help to: --reduce LDL cholesterol and raise HDL cholesterol --lower blood pressure --reduce risk of ovarian cancer --stabilize blood glucose
Most of you probably think of leeks in leek potato soup…but there are so many more ways to cook them! Here's a great feature from Cooking Light to get you started.
I'm hearing more and more that many of you are switching to raw eating, and you're asking me if it's good for PCOS. It's not something that has been formally researched, so my answer is pulled together using what I do know about nutrition.
"Raw" refers to whether or not a food's temperature has exceeded a certain temperature during preparation. I actually tried to write a blog post about this several years ago and at the time could not find a specified temperature defining"raw" for a long time. I finally found something that suggested if it stayed below 124 degrees it would be considered raw. Then, last year, I ate lunch at the Whole Foods Venice, and decided to try a raw lunch for myself. The name of the restaurant that prepared my food was"118 Degrees," referring to the threshold raw temperature. This week, when researching it again, found everything from 104 to 118 degrees listed, without any scientific references for any of those values. It's one reason the diet can't be studied easily — those who follow it have yet to consistently define it.
One of the issues I have with any of those temperatures is that some of the foods popular in the raw community, by virtue of the fact that they grow in tropical climates, are regularly exposed to temperatures exceeding even the highest threshold. The mesquite trees growing in my backyard, yesterday alone, were exposed to an ambient temperature of 118 degrees the entire afternoon. The mesquite beans are dark, meaning they absorb heat and get even hotter. The flour made from them would not technically be raw, though mesquite flour is valued by the raw community. Coconuts, rice…both grow in tropical climates and therefore cannot be guaranteed to be"raw" if the benchmark is the definition above.
I'm assuming for the average person, for whom food is sustenance and not a religion,"raw" more likely means food that was not formally heated during preparation, and for the rest of this article that is the definition I will use.
Though raw eating has not been studied with regards to PCOS, it has been studied. It has been found to have both risks and benefits. The very first study of a raw food diet, published in 1985, found that after 7 months, subjects following this diet dropped their blood pressure, lost weight, and tended to spontaneously give up smoking and drinking.
One study found that raw foodists have lower cholesterol and triglyceride concentrations. However, a couple of other cardiovascular risk factors, serum homocysteine and HDL, were elevated, likely because a raw diet tends to be low in vitamin B12. It would be wise to take a multi-vitamin just to be safe.
Another study reported more dental caries in raw foodists. I'm assuming this is related to the increased carbohydrate and simple sugar content of the diet. So don't forget to brush and floss!
Here's what all you readers really need to pay attention to. One study specifically looked at menstrual function and raw food. It found that about 30% of women studied who were under 45 years of age had partial to complete amenorrhea, with subjects eating high amounts of raw food (>90%) being more affected than moderate raw food dieters. Ouch, ouch, OUCH.
A raw diet is also low in DHA and EPA, the omega-3 fatty acids primarily found in fish. If you're a raw foodist and also vegan, consider taking an omega-3 supplement derived from marine algae.
One benefit to a raw diet is that most people who consume it eat far more fruits and dark green leafy vegetables than they used to. Yay for antioxidants! Interestingly, however, one study found that though raw foodists had higher beta-carotene levels than average, their serum lycopene levels were low. Since lycopene is found in easily found fresh fruits and vegetables like tomatoes and watermelon, this suggests that even when eating raw, it's important to make conscious choices and not limit yourself to a few favorites. It can't just be about carrot juice!
The flip side of all those fruits and vegetables, however, is that protein is a difficult nutrient to get with this diet without soaking and sprouting legumes, in adequate quantities to balance out all of that carbohydrate. It may aggravate your insulin resistance. Be sure to add some protein powder to your cooking to prevent that from happening. Growing Naturals organic brown rice protein isolate powder has designed its product to be raw-compatible; be sure to check them out!
Another natural consequence of cutting out so much protein is that the fat content of the diet naturally increases. And even if it's raw fat, and good fat, it still has calories. I would recommend working out some menus on paper or running them through http://www.fitday.com/ just to be sure the diet doesn't push you in the wrong direction.
How your diet affects your health appears to be more determined by the proportions of carbohydrate, protein, fat, vitamins, minerals, and antioxidants that your diet contains. If you want to do that with raw foods, just be sure you do it right.

We just received another success story. I believe that cyster-to-cyster encouragement goes a whole lot farther than anything we professionals could ever say to motivate, so here is a note from one of our fans.
I know how much you love success stories, so I'm happy to let you know of some progress that I've made in my health. Much of this is a result of implementing ideas from your blog and radio show, so I owe you a debt of gratitude: - I just received some blood test results. My HDL is 69, my LDL is 67 (!), and my triglycerides are 44 (!!). (Thank you, fish oil!) Also, my glucose is 88, and my HbA1C is 5.2. (Thank you, metformin — hopefully someday I won't need you!)
- Since July 1, 2010, I have lost almost thirty pounds, with very few episodes of binge eating.
- I'm faithfully going to yoga every week, and I'm going to run a 5K series this spring — seven races!
- I started sleeping with a sleep mask, as unfortunately it's not feasible for me to sleep in complete darkness.
- I'm still trying to conceive, but am not without hope. My GYN is pushing me to use injectable gonadotropins, but deep down I strongly feel it's not the right path. Even if it means delaying having a baby at my advanced age (38), I'd rather continue to use natural means to try to improve my health first rather than resort to the extreme quick fix.
Each and every one of these letters is like a shot of adrenaline. Because it's not really how much information we put up here that matters, it's knowing it's being incorporated into lives and making a difference.
Thanks for keeping in touch!
(Hee hee, even though you've reinforced my reputation as the person who thinks fish oil is good for everything, it sounds like in this case it really was good for something!)
I've gotten a handful of questions about almonds recently so it seemed like it was time to give them their own personal blog post. It's a good day to talk about the benefits of a handful of almonds, since it's also National Wear Red Day and heart disease is an important risk factor for women with PCOS. They're repeatedly shown to have heart healthy benefits. Eight peer-reviewed studies reported at www.almondsarein.com consistently produced the same results: lower LDL and lower total cholesterol. Other findings included increased HDL, and lower triglycerides.
The disclaimer is that the almonds were used to replace other foods in the diet. In other words, if you know your diet needs some"cleaning up", it won't help to keep eating the problem foods and add the almonds. You need to simultaneously reduce intake of other foods and replace those calories with almonds.
Fortunately, almonds are a tasty snack and can be added to your morning oatmeal, your lunchtime salad, or your favorite muffin recipe. If you'd like to take it one step further and cook more with almonds, the almond people have a great web page with a search engine to give you some ideas.
