Cashew seed extract v diabetes?

This story is doing the rounds of the Internet after a press release by the University of Montreal.

Prof Pierre S Haddad, one of the study authors, is director of the Canadian Institutes of Health Research Team in Aboriginal Anti-Diabetic Medicines at the university. So they look at ‘natural’ remedies and try to work out what is going on.

Cashew nuts are the seeds of the cashew tree. They grow inside cashew apples. Each apple has a single seed.

The nut was not the part tested. It contains oleic acid, not the active ingredient in the study.

The active ingredient was anacardic acid, found in the shell.

The study was done in lab dishes, in pre-muscle cells (which appear to come from mice) and rat liver cells.

What the study found was that extracts from the leaves, bark and apples of cashew trees had no effect. Whereas extract of the seed, and the active ingredient anacardic acid, did appear to induce reactions that would be beneficial in the treatment of diabetes.

Anarcadic acid appears to be restricted to some industrial use and for research labs.

There’s a long way to go from this study to any application in humans.

The article is “Hydro-ethanolic extract of cashew tree (Anacardium occidentale) nut and its principal compound, anacardic acid, stimulate glucose uptake in C2C12 muscle cells,” and it was published in the journal Molecular Nutrition & Food Research.
