There are prescription drugs to help make cells more receptive to the effect of insulin, but lately some studies have shown that regularly ingesting vinegar with a 5% acetic acid content will do just as well and assist with weight loss.
ABC News has an article about vinegar and cherry extract, also shown to improve your blood sugar.
These blood sugar problems also go hand-in-hand with chronic inflammation, linked to heart disease risk and auto-immune disorders. Exercise also helps this constellation of problems, of course.
Just thought I'd post this since I'm probably not the only one concerned about metabolic syndrome and chronic inflammation.
