Grapes

Low glycemic index foods, like grapes, are less likely to cause blood sugar levels to spike when eaten. Their high fiber content makes them a good fruit choice for diabetics.

According to experts, the substances in grapes can lower blood sugar levels. One 16-week trial on 38 men found that those who consumed 20 grams of grape extract daily had lower blood sugar levels than those in the control groups. Resveratrol, a component in grape skins, boosts the sensitivity of insulin, which helps the body process glucose better and lowers blood sugar levels, according to several studies. According to the study's findings, resveratrol makes more glucose receptors on cell functions, which lowers blood sugar levels.
