The Hemp Connection + sucrose

A closer look at sugar and sweeteners

There has been a lot of information circulating around the Internet recently about the dangers of agave nectar. It prompted me to take a little closer look. And I'm glad I did. What I've learned will be part of an ongoing series about the benefits and disadvantages of different types of sugar. It's a complex issue, so to make it more understandable, I thought I'd break it into installments. If you have comments about any of this, please feel free to post. I do moderate comments and won't be putting any up until the series is finished, in case you get ahead of me. I will take your comments into consideration as I proceed with this topic. Thanks for understanding.

According to a 2010 report in the European Journal of Food Safety, a comprehensive review of studies evaluating the effects of various carbohydrates and sugars on metabolism, simple sugars begin to have negative effects on health when they exceed 20% of total calories. That is simple sugars of all kinds--sucrose, fructose, and galactose. Here is how that translates into diets of varying calorie levels, so you can put this information into perspective.

Calorie level Healthful limit for sugar intake, calories Healthful limit for sugar intake, grams
1500 300 75
1600 320 80
1700 340 85
1800 360 90
1900 380 95
2000 400 100
2100 420 105
2200 440 110
2300 460 115

With fructose, the threshold is 7.5% of total calories; more than that, and negative health effects, such as elevated triglycerides, begin to appear. In other words, fructose should be used judiciously, even though it has a lower glycemic index.

Calorie level Healthful limit for fructose intake, calories Healthful limit for fructose intake, grams
1500 112 28
1600 120 30
1700 128 32
1800 136 34
1900 144 36
2000 152 38
2100 160 40
2200 168 42
2300 176 44

A can of soda would contain the following, based on the type of sweetener it contained. It mathematically fits into the above guidelines, but in a way that makes it hard to consume fruits, which also contain fructose, and stay within the calculated limits.
Sugar calories Sugar grams Fructose calories Fructose grams
Cane sugar 150 38 75 19
Beet sugar 150 38 75 19
High fructose corn syrup 140 35 77 19
Agave nectar* 102 25 87 22

*Agave nectar was a little bit harder to figure out. I did manage to find a Denver-based company called Oogave that makes sodas using agave nectar. Their Esteban's Root Beer is what I used for the above analysis.

My first find in a Google search brought me to Full Throttle, an energy drink manufactured by Coca Cola. Unbelievably, the"blue agave" flavor of this product contains no agave nectar at all, is sweetened with high fructose corn syrup, and contains 220 calories in a can! They are definitely hoping the consumer would jump to conclusions about this product.

Are you juicing at home?

Here's how the same volume of a 1/3, 1/3, 1/3 mix of beet, carrot, and spinach juice compares.
Sugar calories Sugar grams Fructose calories Fructose grams
120 24 31 7.8
Calories are not that much different, and total sugar, but the sugar type does. If you were to add fruit, that value would go up.

To give you an idea of what happens when you switch from sugar to agave nectar in the same recipe, I analyzed the same amount of watermelon Arnold Palmer recipe from last week's post. I adjusted the amount of agave nectar based on the fact that agave nectar is 72% sweeter than sugar.

Sugar calories Sugar grams Fructose calories Fructose grams
Made with sugar 20 5 9 2.3
Made with agave 18 4.5 10 2.5
Takeaway messages:
1. Any sweetened beverage,"healthy", or homemade, soda or juice, regardless of how it is sweetened, is a significant source of sugar and fructose. It is a dietary choice that should be made with respect, and sparingly.
2. Soda made in Mexico, even though it doesn't have high fructose corn syrup in it, is still problematic in large quantities.
3. The advantage to agave nectar is that it can help you to cut your total sugar intake, and reduce your glycemic load, but you still need to be aware of the quantity you consume.
