Citrus fruits
Citrus fruits are high in fiber, vitamins, minerals, and antioxidants, all of which contribute to their nutritional value. Citrus fruit is absolutely good for diabetics when consumed in moderation.
Despite the sweetness of many citrus fruits, research suggests that they may help lower blood sugar levels. Citrus fruits are low glycemic, indicating they don't raise blood sugar levels as much as other fruits like watermelon and pineapple. Because they have a low GI, they trigger a slow rise in your blood sugar levels, making them more favorable for people with diabetes. Oranges and grapefruit are high in fiber and include plant compounds such as naringenin, a polyphenol with powerful anti-diabetic benefits. Consumption of whole citrus fruits may improve insulin sensitivity, lower HbA1c, and protect against diabetes.
