You guys still want to rail against this guy based on a few studies on a very select few things. I am talking about the entire gambit of the human diet. This includes fruits, vegetables, grains, lentils, meats, fats, nuts, eggs, dairy, and roots. Cooking some of these things may make them more bioavailable, but what exactly does it do to their nutritional content? More often than not, cooking it will degrade its nutritional content.
Grains and lentils need to be cooked to digest better; that is true. But how much of the full spectrum of the human diet do these consist of? Is anyone really going to try to argue that absolute nutritional values do not suffer even an iota through extreme heating? I am not talking about what makes food more easier for anglo saxons to enjoy. I am talking about macronutrient and micronutrient values across the entire human diet.
In addition, there are multiple studies that show that heating not only decreases nutrient values in dairy, meat, vegetables, fruits, fats, and eggs, but also that heating them will decrease protein and carbohydrate digestibility. Again, grains and lentils do not fall into this category, but I am talking about the entire run of planetary food sources.
Eating raw foods may not be as enjoyable or ideal for many people, but from a nutritional standpoint of all food sources, overall I agree with the juno guy that it is nutritionally better as a whole.
