In this clip, Gabriel Cousins (nutritionist author) attempts to disprove the theory that cavemen all had blood type O and survived on a very high-protein diet. He argues that these claims on which people base ‘eat right for your blood type’ diets don’t hold, and instead suggests that we pay more attention to lectins in food.

Points highlighted:

• Initial humans lived in trees and had a vegan diet like that of chimpanzees
• This diet included roots, berries, leaves (all low-protein)
• It is not protein, but lectins that have the main effect
• Foods high in lectins (e.g. sunflower seeds) should make up no more than 5% of a meal.

The information is interesting, but seems like there’s much more to learn.

Instructional Rating: 2
The topics covered are too broad to take-away much real knowledge.
