A class of compounds found in hops, the crop generally known for its role in beer production, reduces weight gain in obese and diabetic mice, according to a study published Mar. 28 in the open access journal PLoS ONE.
Eight weeks of treatment with the compounds, called tetrahydro iso-alpha acids, also reduced gut permeability and normalized insulin sensitivity markers in the mice, among other beneficial metabolic effects.
Hops have been known to contain anti-inflammatory compounds with potential medicinal uses for metabolic disorders, like insulin resistance and type 2 diabetes, which are associated with low-grade inflammation. These new results suggest a novel mechanism contributing to the positive effects of the investigated treatment, the authors write. The work was led by Patrice Cani of the Université catholique de Louvain in Brussels, Belgium.
