Moderation wins again: Low- and high-carb diets are bad for your health

Eating carbohydrates in moderation seems to be optimal for a long and healthy life, according to an NHLBI-funded study published in The Lancet Public Health journal. The researchers found that low-carb diets that replace carbohydrates with proteins and fat from animals could shorten life expectancy by up to four years.  

Low-carb diets that replace carbohydrates with proteins and fats from plant sources associated with lower risk of mortality compared to those that replace eating carbohydrates in moderation seems to be optimal for health and longevity, suggests new research published in The Lancet Public Health journal.

The observational study of more than 15,400 people from the NHLBI-funded Atherosclerosis Risk in Communities Study (ARIC) found that less than 40 percent or more than 70 percent of calories from carbohydrates were linked with a higher risk of mortality. Moderate consumers of carbohydrates, those getting 50-55 percent of their calories from carbs, had the lowest risk of mortality.
