going bananas
With the recent flurry of paleo-related discussions that have taken place at Fourth Power Fitness, it seems necessary for me to organize my opposition to a deceptively high-glycmeic fruit, the banana.
The vast majority of our ancestors did not inhabit tropical areas; therefore, these bright and colorful, yet saddeningly sugary fruits like mangoes, pineapples, and bananas should not be a part of the paleolithic diet.
The average banana has about 30 grams of carbohydrates. To compare this glycemic index with a few other fruits, it would take 3 cups of strawberries or 1 and a half cups of blueberries or 21 cherries to equal the amount of sugar in what amounts to roughly 1/2 cup of banana. The banana and its tropical friends have slipped into the category of “healthy foods” when their actual macronutrient compositon will reveal their nutirional proximity to such insulin spikers as bread or potatoes. While I haven’t ever heard about any studies that linking banana consumption to the cancers and autoimmune diseases associated with starches, nightshades, or legumes, it seems that the high-glycemic load which serves as the common bond between these non-paleo foods is shared by tropical fruits.
These days everyone seems to know that if you are having muscle spasms, then you need bananas in order to get some potassium into your system to fix the problem. Well, there happen to be two problems with this line of logic. First, bananas typically contain the same amount of potassium as the other most popular fruits do. And some fruits, like kiwis, contain nearly twice as much. The second problem with thinking that bananas will cure cramping lies in the fact that muscle spasms are more related to sodium, magnesium, and the usage of protein for energy during excercise. The “common knowledge” that bananas are a miracle cure for cramping is an unfortunate example of how the general public can be misled about which foods are healthy.
