Recent research, performed by Sara Seidelman, a cardiologist and nutrition researcher from Brigham and Women’s Hospital in Boston, USA, finds that diets which ban entire food groups from the eating plan, for example, ketogenic diet, may actually harm your health.
The research included eating patterns of more than 447,000 people from many countries around the globe. The analysis showed that popular keto diet that strictly limits intake of carbohydrates is one of the diets that may bring long-term harmful consequences. Other diets that should be included in this category are paleo diet, Atkins, Dukan, and whole 30.
Maciej Banach, a professor at the Medical University of Lodz in Poland who helped write the study, says: “Our study suggests that in the long-term, [low-carb diets] are linked with an increased risk of death from any cause, and deaths due to cardiovascular disease, cerebrovascular disease, and cancer.”
Two new independent studies conducted in mice suggest that ketogenic diet, also known as “keto diet”, may improve the memory of old subjects and prolong lifespan.
One study was led by Drs. Eric Verdin and John Newman from the Buck Institute for Research on Aging in Novato, USA. Another study was led by Dr. John Ramsey from the University of California, Davis School of Veterinary Medicine.
Both studies checked the effects of four diet types such as ketogenic, low carbohydrate, high fat, and control diet in mice. A team of scientists from the Buck Institute found that a keto diet prevent obesity, reduced mid-life mortality, and prevented memory loss in mice.
Dr. John Ramsey says: “We expected some differences [in mice fed the keto diet], but I was impressed by the magnitude we observed – a 13% increase in median life span for the mice on a high-fat versus high-carb diet. In humans, that would be 7 to 10 years. But equally important, those mice retained quality of health in later life.”
