High-protein diets like the keto diet
and the Atkins diet are popular these days, but such diets may increase the risk of heart failure in middle-age men, a new study from Finland suggests.
The study researchers analyzed information from more than 2,400 men ages 42 to 60, who kept track of the food they ate for four days. (The men in the study were not told to follow any particular diet.) Then, the men were divided into four groups based on how much protein they ate, with the lowest group consuming about 78 grams a day, on average, and the highest group consuming 109 grams a day. The participants were then tracked for 22 years, during which about 330 were diagnosed with heart failure.
