Diabetics and Grapes: Experts Reveal Impact on Blood Sugar, Portion Control is Key

• Grapes have a Glycemic Index (GI) between 53-59, placing them in the low to medium category, meaning they don't cause a sudden sugar spike.
• Grapes contain beneficial components like resveratrol (an antioxidant that improves insulin sensitivity) and fiber in their skin, which slows sugar absorption.
• Diabetics should practice portion control, limiting intake to about half a cup (10-12 grapes) at a time to avoid blood sugar spikes.
• Avoid grape juice as it lacks fiber; whole fruit is better. Eat grapes in the morning or as a mid-day snack, paired with protein.
• Black or red grapes may offer more benefits due to higher anthocyanins and resveratrol, but all types are acceptable in moderation, as per ADA.
