To form a menu for a diabetic person for a week, a nutritionist analyzes health goals, lifestyle and food preferences, according to Mayo Clinic. A diabetes diet involves eating healthy, nutritious foods in appropriate quantities and forming consistent eating habits.
A nutritionist or dietitian helps a person with diabetes come up with a meal plan that involves a significant amount of fruits, vegetables, whole grains, fiber and nutrient-rich foods, notes Mayo Clinic. A nutritionist also provides advice on the difference between good and bad fats and carbohydrates. The diabetes diet also requires the person with diabetes to avoid trans fats, saturated fats and cholesterol as much as possible.
In order to keep blood sugar levels regulated, a nutritionist or dietitian may recommend a plan that involves the food lists system, the glycemic index or carbohydrate counting, states Mayo Clinic. The food lists system allows people to track servings of carbohydrates, protein sources, fats and make substitutions as desired. The glycemic index allows people with diabetes to track the effect foods have on their blood sugar levels. The nutritionist teaches a person with diabetes how to accurately count and track carbohydrate intake, which makes it possible to adjust insulin use accordingly.
