Paleo dieters may be wrong about not eating starchy carbs听when they attempt to mimic what听our ancestors ate, according to 听to be published in the September听2015 issue听of the听Quarterly Review of Biology. The study, currently available online, suggests that starchy carbs were essential to the evolution and growth of the human brain, despite the common paleo approach to a high-protein, low-carb diet.听
Previous studies connected human brain development with the discovery of stone tools, which caused humans to shift from a mostly plant-based diet to a meat-based one, according to from the University of Chicago. But听after taking into account genetic, physiological, archaeological, anthropological, and anatomical data,听researchers believe we also have digestible carbohydrates to thank.
The paleo听diet, , is based on听what our ancestors ate until agriculture came along. Paleo supporters believe听the healthiest diet听is composed听of听fish, meat, vegetables, fruit, polutry, and nuts听and听cuts out听grains, dairy, and听excessive sugars. (However, followers of the ,听an offshoot of the typical paleo program, do eat refined products during endurance sports.)听Most believe the Paleo diet stemmed from a 1985 article published in the听New England Journal of Medicine, and some feel that it鈥檚 a way to deal with the rise in diabetes, high blood pressure, and obesity.
But Karen Hardy, lead author of the recent study, says carbs听are vital to a high-functioning brain. The key is to eat the right type and the right amount.听She believes the problem today鈥攁nd the reason starchy food sometimes has such a bad reputation鈥攊s from overeating heavily processed starchy food. That鈥檚听what can cause weight gain, Hardy told 国产吃瓜黑料听in an email.听She recommends avoiding high glycemic index starches, such as white rice and white bread.听
鈥淔oods such as tubers and starchy seeds and nuts are the ones to go for,鈥澨鼿ardy wrote.
