- Food exchange lists help in preventing both hypo and hyper glycemia.
- Diet is based on type of insulin intake

- Carbohydrate: High carbohydrate and high fibre diet improves monocyte insulin receptor binding capacity, 60-65% total calories.
- Proteins: A diet high in protein (20% of k cal). Requirement for adults is 1gm/kg body weight and for children 1-1.5g/kg body weight
- Fat: 15-25% of total calories from PUFA
Vitamins and minerals:
- Needed to overcome oxidative stress and deficiency
- Vitamin C, vitamin E, magnesium and zinc are needed
- Normal requirement of calcium
- Vitamin D deficiency contributes to Impaired Glucose Tolerance
- Chromium supplementation reduces insulin dose
Dietary fibre: About 25-50g of dietary fibre and complex carbohydrate for type I and II diabetes.
- Decreases insulin requirements
- Increases peripheral tissue insulin sensitivity
- Decreases serum cholesterol and triglycerides
- Aids in weight control
- Decreases blood pressure.
Artificial Sweeteners: Sugar substitutes, non caloric and high intense sweetners. Ideal sweetener:
- Pleasant taste with no after taste
- Sweet as sucrose
- Colourless, odourless
- Readily soluble, stable
- Nontoxic, does not promote dental cavities
- Functional and economically feasible
- Without metabolic abnormalities
Low calorie sweeteners
- Polyols: 2.4 k cal/ g, synthesized from carbohydrate like starch, sucrose, glucose, invert sugar, xylose, sugar alcohols xylitol, sorbitol, mannitol, maltitol, lactitol etc 40-50g/day for adults and 30 g/day for children.
Non-calorie sweeteners
- Cyclamate: 30 times sweeter than sucrose, heat stable.
- Acelsulfame-K: Synthetic derivative of acetoacetic acid, non digestive, after taste, high concentration has metallic flavour, 200 times sweeter than 3% sucrose heat stable.
- Alitame: Di peptide based amide, 2000 times sweeter than sucrose.
- Aspartame: Made of aspartic acid and phenylalanine 180- 200 times sweeter than sucrose. Not heat stable.
- Saccharin: Sodium ortho benzene sulphonamide, stable, 300 times sweeter than sucrose.
- Sucralose: 600 times sweeter than sucrose easily soluble in water, stable
- Oral hypoglycaemic drugs: Sulphonylureas, biguanides
