New research that’s being called the most comprehensive study ever undertaken of carbohydrate intake suggests that cutting carbs might also cut lifespan by up to four years, USA Today reports.
“The peer-reviewed research published in the medical journal The Lancet Public Health suggests low and high-carb diets could shorten life, and diets including some carbs could promote a healthy lifespan,” the story reports.
“The study analyzed self-reported data from more than 15,400 middle-aged Americans who participated in the Atherosclerosis Risk in Communities Study,” USA Today reports. “The dietary patterns researchers found were compared against additional studies that included 432,000 people in more than 20 countries.”
The report notes that self-reported data can be flawed, because it relies on the participants’ memory. “Another limitation of the study: Diets were measured only twice during the 25-year study period, at the start of the study and again six years later,” the report also notes.
USA Today adds: “Researchers concluded that people who ate a moderate amount of carbohydrates lived four years longer than those with low-carbohydrate consumption and one year longer than those who ate a lot of carbohydrates. Low-carb diets were defined as less than 40 percent of calories from carbohydrates and high-carb diets were more than 70 percent of calories.”
