If the 'paleo' diet is so good for you then why

This is all very timely considering the USDA just exchanged the food pyramid for the nutrition plate. Apparently, multi-colored circles are much less complicated than multi-colored triangles.

Humans are omnivores. We can survive eating pretty much anything, as long as it’s not outright poisonous. In correlation, we really don’t need any one food to survive. There is no silver bullet to eating the right foods. That said, pretty much everyone agrees on the principle of garbage in, garbage out. They just don’t agree on the definition of “garbage” when it comes to nutrition. In my opinion, white crystals/powders are the garbage, but I digress.

The problem with all of the nutritional methods floating around is that, in order to get airtime, someone thought it was a good idea to slap a crazy label on them (South Beach, grapefruit, Atkins, Paleo, Vegan, raw foodie, even omnivore). As soon as they do that (and reduce it to terms easily grasped by the general public), they draw a line in the sand, effectively creating their own opposition. Food is too emotional (nigh on religious) to people to expect everyone to align with any concept other than their own preconceived notions. If they’ve been living that way for decades, it’s very difficult to get across to people that it’s okay, much less healthier, to eat a occasional meal without animal products or that you don’t need a quart of sugar water with every meal.

Side note: tasty sugars and fats at extremely low cost will always trump common sense in the average human.

Agree, btw- millet, rice and oats, buckwheat have no gluten. In the end it all comes to balance.
