You can eat pumpkin, but you can’t replace your staple food with pumpkin.
Pumpkin has a glycemic index of 75, which is a high-glycemic food, indicating that the carbohydrates in it are not diabetes-friendly. But it has the advantage of being low in sugar, so it’s not a burden when eaten in small amounts or mixed with other dishes. However, many people will use pumpkin instead of a staple food, which is incorrect.
Different varieties of pumpkin contain between 0.8-1.7 percent protein, 0.2-2.0 percent starch, 2.3-8.4 percent soluble sugar, 0.4-0.8 percent crude fiber, and 0.4-0.8 percent vitamin C. Vitamin C content is between 3mg-24mg/100g and carotene is between 3mg-32mg/100g. It can be seen that its caloric and nutritional value is closer to that of vegetables and fruits, and is far from grain and legumes, and its protein content is too low, so you can’t use pumpkin as a complete substitute for staple foods.
But people with diabetes who are overweight and need to lose weight can eat some pumpkin instead of a portion (1/4 to 1/3) of their staple foods.
