A new study in the journal Molecular Nutrition and Food Research suggests polyphenols, found in grape seeds, may protect against oxidative stress linked to obesity. Scientists fed hamsters a high-fat diet supplemented with Chardonnay grape seed extract for 12 weeks. At the end of the experiment mice not given the grape seed extract had more abdominal fat than mice given the extract. Also, data revealed the high-fat group had increases in blood sugar, triglycerides and insulin resistance, while the extract group was “in part” protected from these effects; via Food Navigator.
In October, grapes were shown to lower blood pressure and reduce heart damage, but lots of plant foods, like blueberries and kiwis, contain polyphenols, antioxidants and other nutrients shown to prevent cancer. Nuts and seeds are other excellent sources phytochemicals and fibers that prevent blood vessel inflammation, raise good cholesterol and lower blood glucose.
I snack on grapes when I’m chained to my desk blogging. Good thing I find them on the cheap! As a kid, my grandfather had an old-school Italian grapevine growing all over the garage. It was cool.
