He makes some good points.
I'm not going to get scientific, but there are a few things that more people need to understand:
- There's more than one way to do things. Some people eat gluten, grains, peanuts, whatever and have absolutely no problem. I know people who have gone through the entire process of eliminating them from their diet, and they saw no difference, so they added them back in. This is purely anecdotal, but there are plenty of people who handle gluten just fine.
- Condemnation of a certain food group, macronutrient, vitamin/mineral, whatever, is completely useless if you don't consider the context of the entire diet. There's always a shift in what the culprit is: is it carbs? Is it gluten? Is it fat? This is something Tom Venuto terms "information isolation", and it's a very narrow way of thinking. Blaming one small aspect without looking at the entire context of the diet is just plain misleading, in my opinion.
Sorry for the rambling, just my 2 cents. I just wish people would understand that there is not only one way to eat to achieve great results regarding health and/or body composition. People have seen great results with the Primal methods of eating. People have also seen great results eating a higher carb, lower fat diet. Some do awesome on ketogenic diets, some do terrible on them.
I think there are arguments that can be made in favor and against both sides of the coin, but what really matters is what's most effective for you in your situation.
