A healthy low-calorie diet that contains plant products can help us improve the level of sirtuin 1 (SIRT1) protein production that is known to increase life expectancy. A team of scientists from Krasnoyarsk conducted an experiment to see how buckwheat affected the health of rats. The only known method to optimize the level of this protein is calorie restriction. But why would healthy people be subjected to calorie restriction without any medical emergency? According to the researchers, a buckwheat-based diet helps to increase the level of SIRT1 protein that protects all the cells of the body and enhances longevity. At the same time, there is no need to starve. The results of the study were published in the Journal of Cereal Science.
