Okinawans have eaten dramatically more pork daily than the rest of Japan; they ate pork with almost every meal. And on top of pork, Okinawans have also eaten similar amount to fish to the rest of Japan.

Okinawans also eat dramatically less rice and noodles than the rest of Japan - so less carbs.

Vegetables were always fried in pig lard.

Plant-based fake news sources have been describing Okinawans as eating "mostly sweet potatoes and mostly plant based".

In 1949 US government conducted a survey on Okinawan food intake, and subsequently compiled a report. US government report stated that Okinawans in 1949 ate lots of sweet potatoes.

The problem is that Okinawa was in post-war ruin with extreme food shortages until early 1950s. Okinawans were literally starving to death in the late 1940s. American troops completely destroyed all the pre-war Okinawa pig inventory - around 100,000. Plus American troops claimed the pig farms land for military bases.

So Okinawans in late 1940s planted and ate sweet potatoes in the last-ditch effort to not die from starvation.

By early 1950s Okinawans were able to restore their pig inventory and went back to eating mostly pork and frying everything in pork lard.

The plant-based fake news have been using this irrelevant 1949 US survey as a "proof" that Okinawan food is based on sweet potatoes.
