The paleolithic diet myth is the most recent in a long list of food and diet fads that have been debunked by skeptics for years. I’m sure there were paleolithic cavemen skeptics 20,000 years ago who grunted, “this diet sucks.” If they actually ate that diet.
Food fads are so enticing. Eat this to make your immune system strong. Don’t eat that because it causes cancer. But do eat this because it reduces your risk of cancer. Eat this. Don’t eat that. Drink this. Eat more of that.
My thoughts have always been that the human physiology is amazingly resilient, and as long as you have no chronic diseases nor chronic malnutrition, there is nothing one can do that will make the situation much better or much worse.
Yes, maintaining levels of certain nutrients, such as vitamins C and D, iron, and others, are critical, but in the modern world, it’s almost impossible to miss out on those micronutrients. Yes, we should limit fats and “sugars”. But the thing is human physiology is complex, so marathoners eat lots of carbohydrates, and they are mostly healthy. It all depends.
And then there’s cancer – it stokes our fears about foods. You’re not going to prevent or cure cancer with supplements (or presumably foods that are rich with those nutrients). Antioxidants don’t really help prevent cancer. Soy won’t stop certain types of cancer. Nor will certain foods make you lose weight. There really are only a few ways to prevent cancer,
Most of these beliefs about foods, health and weight loss are based on either a boatload of anecdotal evidence, or use very preliminary laboratory research, make a leap of faith, and assume that laboratory evidence is equivalent to clinical evidence. Then, when the gold standard of research, a randomized clinical trial is done, the results generally show nothing. And in some cases, the negative effect is with the supplement or food.
And if you’re looking to try the newest diet craze, be aware that most fad diets just have no long-term successes, and may actually do harm. The newest one is based on the paleolithic diet myth.
