The Claim

Higher consumption of total carbohydrates from cooked grains is associated with increased relative abundance of the bacterial genus Bifidobacterium in healthy U.S. adults.

In plain English

In healthy U.S. adults, eating more total carbohydrates from cooked grains is linked to higher levels of Bifidobacterium bacteria in the gut.

See the scientific wording

Higher consumption of total carbohydrates from cooked grains is associated with increased relative abundance of the bacterial genus Bifidobacterium in healthy U.S. adults.

Why this might work

When grains like pasta, bread, and rice are cooked and then cooled, they form a type of starch that human digestion cannot break down. This starch travels to the colon untouched, where Bifidobacterium bacteria use special enzymes to break it apart and use it for energy. As these bacteria feed on the starch, they multiply and become more numerous in the gut.

    People who ate more pasta, bread, and rice had more of a helpful gut bacteria called Bifidobacterium, according to this study. It’s like the bacteria like to hang out when you eat these grain foods.
