Diabetics can eat crab, but they should be careful about how much they eat.
Crab is delicious and popular, and people with diabetes can also eat crab. Crab is rich in nutrients and is a high-protein food. The dietary principles for diabetics call for protein to account for 12%-20% of total calories, at least one-third of which comes from animal-based high-quality proteins and soy protein.
But when eating crab, you should pay attention to the serving size. The Chinese Dietary Guidelines recommend a daily intake of 40-75 grams of aquatic products, which translates into a maximum of half a kilogram of crab a day. In addition, the crab yolk of crab contains more fat and cholesterol, and fat should account for 25%-30% of total dietary calories for diabetics, while cholesterol intake should be controlled at less than 300 mg, so from this perspective, diabetics should also pay attention to the intake of crab, eating no more than one medium-sized crab each time, and should be controlled at less than three per week.
