Diabetics can eat canned vegetables as part of an ideal diet as long as they are without added sodium, fat or sugar, as the American Diabetes Association explains. If the canned vegetables have added sodium, individuals can drain and rinse them before cooking them in fresh water. This reduces the amount of sodium on the vegetables.
To foster good health, diabetics should try to eat three to five servings of vegetables each day, but more is even better, as the American Diabetes Association reports. A serving of vegetables is typically one-half cup of cooked vegetables or vegetable juice or one cup of raw vegetables.
The healthiest diets for diabetics include vegetables, fruit, whole grains, lean meats and nonfat dairy products. The foods should be rich in vitamins, minerals and nutrients with controlled portion sizes. Diabetics should also incorporate foods high in fiber in their diets by including nuts, wheat bran, beans and lentils, as Mayo Clinic advises. Fish is a good alternative to fatty meats, and tuna, mackerel and salmon also have omega-3 fatty acids, which help lower triglycerides. Diabetics should try to include those fish in their diets at least twice per week, and they should also periodically incorporate healthy fats such as those in nuts, olive oil and avocados.
