Lesson 30:Diabetes – Dietary management

Diet

  • Food exchange lists help in preventing both hypo and hyper glycemia.
  • Diet is based on type of insulin intake
  • Table:Types of insulin and their action

    Type Onset hours Peak Action hours Duration hours
    • Rapid action-short duration- Regular soluble crystalline semi lente

  • The action of insulin and the peak absorption of carbohydrate should be at the same time.

  • Insulin and meal distribution of calories

  • 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
