Okinawa and Lard

The inhabitants of Okinawa, an island prefecture of Japan, are one of the longest-lived populations in the world. Their diet and lifestyle have been thoroughly studied for this reason. Papers typically focus on their consumption of vegetables, fish, soy, sweet potatoes, exercise, and the fact that some of them may have been mildly calorie restricted for part of their lives.

The thing that often gets swept under the rug is that they eat lard. Traditionally, it was their primary cooking fat. Of course, they also eat the pork the lard came from.

I'm not saying lard will make you live to 100, but a moderate amount certainly won't stop you...
