Start talking about added sugar, without even getting into the differences on a biochemical level of fructose versus other sugars, and the rebuttal is likely to be, “But fruit has sugar.” At the most base level this argument is true and, in fact, fruit contains the very sugar type—fructose—that appears to be the source of our dietary ills.
An apple, according to data sources that I averaged across the internet, will contain approximately 65 Calories, 13 grams of sugar in the form of fructose, and 3 grams of dietary fiber. Compare that with a twelve ounce can of Coca-Cola which has 143 Calories, 40 grams of sugar in the form of high fructose corn syrup, and no dietary fiber. Here it is in a simple chart form:
Sure, fructose is contained within the natural sugar of an apple in roughly the same proportion as it would be in a can of Coca-Cola. However, to get the same amount of fructose as the Coca-Cola you would need to eat three entire apples. On par, you would still be slightly ahead because the apple contains dietary fiber and other nutrients beneficial to the body’s function. Your mother was right about soda being just a bunch of empty calories.
Not that I would suggest undertaking this experiment, but drink an entire can of Coca-Cola and tell me how you feel. Do the same thing with three apples and tell me how you feel. I am certain that there will be major differences in satiation. Three average apples will fill your belly with approximately 35% of your daily requirement. It’s not a pound of Brussels sprouts, but it will get your insides a moving if you know what I mean.
There is a problem in demonizing an entire category of nutrients. If you say fat is bad then you ignore the beneficial fats. If you say carbohydrates are bad then you have dismissed a key source of the body’s energy system. You get the idea.
Within those broad categories, however, there can be bad actors. All fats are not bad, but trans-fats might as well be the Red Skull of the nutritional world. Seriously, when have either the Red Skull or trans-fats done something good?
It’s the same way with carbohydrates and, specifically, sugars. If our body is capable of registering the calories from a sugar—i.e. every sugar except for fructose—than it has a role to play in our nutrition. Fructose, in the form added to our food, is a bad actor because it screws with our bodies in a myriad of ways.
It looks like the experts are finally getting on the “added sugar is pretty bad” bandwagon. And maybe that egg yolk won’t kill you after all.
