Early-Stage Discoveries: Flaxseed improves gut bacteria

In the lab, mice ate a high-fat diet with no fiber, with cellulose fiber or flaxseed fiber, or a standard soy-based diet. 

After 12 weeks, those on the high-fat diet with or without cellulose had fewer good gut bacteria, more bacteria linked to obesity, and lower fatty acid levels.

Those taking flaxseed were more physically active, had less weight gain, better glucose control, and higher levels of beneficial fatty acids, which doctors said come from fermenting the glue-like layer of the flaxseed shell.
