Legumes are the richest plant based proteins and contain the third highest protein content in a single serving after meat and fish. However, as compared to meat and fish, it contains much less calories and fat yet gives a whole lot of fiber which helps to prevent diabetes and heart disease. The high fiber content contributes to a low glycemic index (GI) which means that glucose is slowly being released into the bloodstream. This effect control spikes in blood sugar especially after meals and is very beneficial to managing a diabetic blood sugar.
If legumes are not currently a part of your diet, I suggest you correct that to start off this new year. If you don't enjoy a bowl of legumes, add them to soups, salads, etc. but work them into your diet.
