@Serotoninskeptic said in Reasons for longevity in Japan?:
Do any of you remember the people Dr. Peat sometimes mentioned in interviews who ate almost nothing but potatoes/sweet potatoes all year, plus pork one week a year? He mentioned they had good muscle mass despite low protein, but I forgot whom he was talking about and I lost my notes.
Could it have been the Tukisenta?
"The diet of the Tukisenta in New Guinea was studied in 1973. Their diet consists almost entirely of sweet potatoes. The Tukisenta were lean, healthy, and had little to no sign of heart disease or other diseases of civilization"
Could be. I found the interview (part 1, it starts at 16:25): https://oneradionetwork.com/dr-ray-peat-ph-d-answering-a-plethora-of-questions-regarding-health-diet-and-nutrition-january-1-2014/
Altough I didn't understand what he was saying. Something with ...inions?
Edit:
Here is another one, starting at 01:13:00. That was the interview I remembered: https://oneradionetwork.com/dr-ray-peat-ph-d-got-milk-milk-is-a-good-food-really-july-18-2019/
Pacific islanders, so could be Tukisenta.
