Our eating habits have been formed by mass marketing for many decades so I would not call them normal. Even the fresh fruit and vegetables I see in the supermarkets (Coles and Woolworths in Australia) do not look normal.
Seeds - sunflower, pumpkin, *
Seafood - Salmon, sardines, mussels
Reds - Tomato, red peppers
Insects - Crickets
Everyone can debate the merits of livestock, cereals, roots, legumes, extracted seed oils, saturated fat, cholesterol, refined sugar, top feeding fish, alliums, brassicaceae. But the other things listed above are about as universally and unequivocally considered healthy with the understanding of food we have, with regard to commonly available foods in a western diet.
* almond, peanut, walnut, pistachio, pecan, cashew, macadamia too if fodmap issues arent a concern. Same with alliums, brassicaceae, legumes.
