Eating Carbs Could Help You Live Longer, According to Science
Now, this is news worth sharing!
There is no denying the fact that Southerners love carbs in almost any form. In fact, carbs make up the bulk of the Southern dietary staples—there are biscuits and grits and sweet potatoes and hush puppies and corn bread and macaroni and cheese, the rice in red beans and rice, the dumplings in chicken and dumplings. Even without getting to the dessert table, the list goes on and on. It’s hard to imagine what Southern cuisine would look like without carbohydrates. Luckily, if you’re a carb-loving Southerner, there’s some good news: eating a lot of carbohydrates just may help you live longer.

Scientists have been trying to unravel the mystery of longevity since, well probably since the first scientists got a grey hair. According to British news outlet the BBC, aging scientists have started looking at the long life-span of residents on Japan’s Okinawa Islands. The residents there tend to live longer than average folks. Out of every 100,000 inhabitants 68 Okinawans live 100 years or more. That’s over three times the numbers found in the same size of the U.S. population. Even by the standards of Japan, where people tend to live longer, Okinawans are remarkable. They have a 40% greater chance of living to 100 than other Japanese people.
The Okinawa Centenarian Study (OCS), has been investigating the health of the islands’ aging population since 1975. By 2016, the OCS had looked at the health habits of 1,000 centenarians from the area. They found that the Okinawan centenarians managed to delay many of the usual effects of aging, with almost two thirds living independently until the age of 97.
So, what’s their secret? It might be their carb-heavy diet. Scientists have realized that Okinawans have a “peculiarly high ratio of carbohydrates to protein” in their diet, with a lot of their calories coming from—wait for it—sweet potatoes. Of course, sweet potatoes are a healthy, complex carb, but still, it’s a staple of the Southern diet and we’ll take it. Okinawans also eat an abundance of greens and yellow vegetables, which could easily be collards and green beans and squash. While they do eat pork, fish, and other meats, it’s typically a small component of their overall consumption.
Scientists are realizing that the Okinawans heavy intake of carbs may help their bodies fend off some of the effects of aging. It’s all about finding the right balance between carbs and proteins and what scientists are now calling the “Okinawan Ratio” is a diet based around a ratio of eating 10 carbs for every one protein. Sticking to that dietary ratio may help protect people from various age-related illnesses, including cancer, heart disease, and Alzheimer’s. Have there ever been sweeter words?
