High-Fiber Diet Might Protect Against Range of Conditions

JAMA. 2019;321(17):1653-1655. doi:10.1001/jama.2019.2539

The popularity of low-carb diets, such as Atkins and keto, have helped give the macronutrient a bad name, and in part, it’s deserved.

“Have carbs got a bad reputation? Certainly…for a very understandable reason,” said Jim Mann, MB, ChB, PhD, a professor in human nutrition and medicine at the University of Otago in New Zealand. “They are highly refined, and, in many countries, sugar intake is high.”

But just as there are “bad” fats and “good” fats, there are also bad carbs and good carbs. “We showed very clearly in our work in diabetes that the benefits of carbs came from the good carbs, and the good carbs are not high in sugar,” Mann said. “They are high in fiber.”
