Ultimately I’m asking if such a diet is possible with only whole foods, and what potential health consequences this would have for a very active individual.
a good part of the world’s diet is made up of unrefined foods (although countries like the USA and western Europe eat more processed products), in fact historically, most of the food is based on whole foods see the middle ages the diet was made up of beans, oats, wheat, barley, cruciferous vegetables, wild vegetables, mushrooms, full-fat dairy, buttermilk, butter, dark bread (dark flour), dark flour (even less refined flour than wholegrain), fish (depends on geographical location) ), beef (occasionally), pork (occasionally), poultry such as ducks and geese (rarely), cold cuts, cheeses, eggs (rarely) and game meat, disregarding ignorance, lack of hygiene, social conditions and constant wars was a pretty normal diet that brought humanity to the present period, I cited the Middle Ages because most of the history taught in schools is of Eurocentric origin.
