Humans are one of the most adaptive species on the planet. I don’t think they need a “fixed” diet of anything. Herbal supplements are passing fads. The typical American probably has 10x the nutrients he needs.
My dad lived to 93. He ate hot dogs, pork & beans out of the can, TV dinners, banana splits, vienna sausages, all kinds of crap. I think he lived so long because he was happy and active. I taught him how to use the internet when he was 80. I also taught him how to ride a skateboard in his 80’s.
About 4 months before he died, he told me he wanted to die because he felt he had done everything possible in this life and he wanted to see what was next. I asked him if there was any information he wanted to leave with me before he went, or if there was anything he would have done differently. He said “avoid fat and take care of your teeth”. So I have. The day he died, he woke up, went to church (he NEVER went to church before), came home, lay in his bed, and died. The doctor said it was “sudden cardiac arrest”. He never had any heart problems. He was a doctor.
