I am following the gatherer’s diet and walk 5 miles every day when I can. I am in my late 80’s now. Never had any health issues with heart, stroke, diabetes, joint aches, or constipation (in my opinion prime cause of colo-rectal cancer). I will continue to follow my genes evolved over multiple million years. My mother ate meat only once a week and fasted one whole day every month. She lived to age 103 without any serious health issues. But feel free to follow whichever diet is a joy in your life.
Well....yeah. But there are diets/genetics that have been fine-tuned over time. The Japanese...probably any island people...have a fiet heavy in fish. The Mediterranean diet is kind of distinct. The North American diet war varied, but included corn, which the Euros imported. Are uou following a paleo diet? Hard to argue with whole foods...nuts, seeds, grains. Some people ought not eat nightshades...potatoes, tomatoes, eggplant, peppers....
