Starch is so great. Think of all the things you can do with starch. But is a starch-based diet the healthiest? Here is a debate between vegetarian nutrition experts on the primacy of starch.

Every single society that has ever existed survived on a starch-based diet, says John McDougall. McDougall is taken aback by “niche theories,” the point he makes is somewhat overlooked by other nutritionists. On the other hand, every single person has a different metabolic rate and needs to limit their caloric intake to suit their individual needs, says Joel Furston. There is a perfect balance between vegetables and starches and each person needs to ‘do the math’ to figure out what is best for them. I don’t see these two views as incompatible – because McDougall is making his point far too generally, and Furston is confining the discussion to individuals.
