Yes, people with diabetes can eat prawns. These are the best and safe seafood for diabetics as they do not have any harmful impact on the blood glucose level. Prawns have minimal carbohydrate composition along with a high number of proteins and healthy fats such as omega-3 fatty acids. High proteins and fats maintain the nutrition value of diabetics as they are digested slowly as compared to carbohydrates and thus do not spike blood glucose levels. [1] 

Proteins and omega-3 fatty acids in prawns stimulate the synthesis of insulin which regulates the blood glucose level. Omega-3 fatty acids are ideal for preventing the cardiovascular risks of diabetes as these keep the triglycerides and cholesterol levels in control. Prawns contain adequate levels of potassium which regulates the body’s electrolytes and prevents inflammations and muscle cramps. Thus, prawns have lots of benefits for diabetics along with providing healthy nutrients and are considered ideal foods for diabetics. [2]
