Understanding your foods’ glycemic index (GI) can be incredibly beneficial when maintaining a healthy diet. The glycemic index (GI) measures how quickly a food raises blood sugar levels after eating. Foods with a low GI (55 or less) are digested and absorbed more slowly, gradually increasing blood sugar and insulin levels. This is especially important for managing weight, supporting vitality, and preventing chronic diseases like diabetes.

Low-glycemic fruits like cherries or a small cucumber salad make great mid-morning snacks, keeping hunger at bay without causing a spike in blood sugar.

High-Glycemic Fruits to Avoid
While low-glycemic fruits and vegetables are beneficial for maintaining stable blood sugar levels, it’s also important to be aware of high-glycemic fruits that can cause rapid spikes in blood sugar. Here are a few to limit or avoid:
i). Watermelon: With a glycemic Index of 72, Watermelon is refreshing and hydrating, but it has a high glycemic index. While it’s okay to enjoy in moderation, it’s best to avoid consuming large quantities if you’re watching your blood sugar level.
ii). Pineapple: Pineapple has a GI of 66, making it a fruit that can spike blood sugar levels. Enjoy it in moderation and combine it with lower GI foods.
