Scientists Warn: America’s Most Popular Cooking Oil May Be Harming Your Intestines

UC Riverside researchers found that mice on a soybean-oil-heavy diet showed disrupted gut microbiomes and more harmful bacteria.

The mice also developed a weaker intestinal barrier, which could increase intestinal permeability and inflammation risk.

The effects were linked to linoleic acid, a major component of soybean oil.

The team cautioned that these results do not prove the same health effects in humans, but they may shape views of processed and restaurant foods.
