5 Fruits Diabetic Patients Should Avoid During Summer

Eating fruits in summer is usually beneficial, but if you're living with diabetes, not all fruits are safe. Some contain high levels of natural sugar (fructose) and can cause a sudden spike in blood sugar levels. This can harm the heart, kidneys, and eyes.

Health experts warn that people with diabetes should avoid fruits with a high glycemic index (GI), which can rapidly raise blood glucose levels. In severe cases, blood sugar can rise above 300 mg/dL—posing serious health risks.
