One of the more frustrating diet plans, to me, is the blood type diet. The idea is that you have a certain blood type because your ancestors were from a certain place, so they adapted to a specific diet. You are then instructed, based on having O, A, B, or AB blood, to eat according to the prescription. Vegetarian, highly carnivorous, a mix of the two, grains or no grains, etc.
The diet has no real science backing it. Only a very dubious theory.
The theory collapses when you consider that every indigenous population of the world has all the blood types: A, B, AB, and O. It’s also highly problematic when you consider how much genetic mixing and nomadism we’ve had in recent centuries. Few people have both parents going back to the same origins
You may feel better because the author of the nutrition program eliminates gluten from the type O diet. That will make everyone feel better, as grains have been hybridized and are causing many people problems.
And he tells all type A’s to eat vegetarian, which is actually a good diet for most, if not all, people.
(As always, I refuse to take a stand on whether a limited amount of animal protein is good or desirable or at least acceptable—but it’s clear that more plants, and less animals, is across the board, more environmentally sustainable and more health-promoting.)
And you may feel better because regardless of your blood type, you’re told to eliminate processed foods such as white flour.
