Dietitian Jocelyn Laurent’s advice appears to be based on known nutritional information and the effects of various foods on blood sugar. Blueberries are actually considered beneficial for people with diabetes for several reasons:
Low in fructose: Unlike many other fruits that can raise blood sugar levels due to their high fructose content, blueberries are lower in fructose, making them a better choice for people with diabetes.
Rich in Polyphenols: Polyphenols in blueberries are known for their antioxidant properties and potential for improving insulin sensitivity, which may help prevent or manage diabetes.
Vitamin and Mineral Content: High levels of vitamins and minerals such as vitamin C, vitamin K and manganese promote overall health and may support normal kidney function and improve metabolic processes.
Stabilize Glucose Levels: Eating blueberries may help promote more stable blood glucose levels, which is especially important for people with diabetes, as glucose fluctuations can lead to long-term complications.
Weight and Glucose Control: Since blueberries do not promote excess weight gain, which is a risk factor for the development and worsening of diabetes, they can be a good alternative for those watching their weight.
It should be noted that while blueberries can be a healthy choice for people with diabetes, it is still important to consider the overall balance of the diet and be mindful of other aspects of a diabetic eating plan, including portion control and overall carbohydrate balance. As with any food, blueberries should be consumed in moderation and in combination with other healthy foods.
