Grapefruit Juice Just as Effective as Metformin, Says Study
If you like sipping tart, lightly sweet grapefruit juice, then you may have an advantage when it comes to diabetes prevention.
A study published in the journal PLOS ONE found that grapefruit juice might have glucose-lowering effects that make it just as effective as the diabetes drug metformin.
Researchers gave mice one of three beverages: sweetened diluted grapefruit juice, sweetened water, and water that contained metformin. They found that mice who ate a typical fatty American diet and drank grapefruit juice had a 13%-17% drop in blood glucose levels and a threefold decrease in insulin levels (meaning the body is churning out less insulin because blood sugar is being processed more efficiently), compared to the mice who drank sweetened water. They also lost 18% more weight.
The research team also found that mice who consumed grapefruit juice experienced the same reduction in blood glucose levels as the mice who drank metformin-spiked water.
The amount of grapefruit juice used in the mice equates to about four cups a day in people, says the study.
Caveat: This study was funded by the California Grapefruit Growers Cooperative. (Yes, a grapefruit producer!) Does that mean the experiment was rigged? Not so, says the study’s co-author, a professor and chair of nutritional sciences and toxicology at the University of California, Berkeley, who says that the data is accurate and the study’s funders had no hand in the experiment or the presentation of results.
