While it may not be the biggest breakthrough it does have surprising efficacy with a range of biological problems and diseases. Dietary treatment of diabetes is probably the oldest technique for controlling the disease with numerous methods being suggested before the discovery of insulin in 1922. As the body of a diabetic struggles to cope with food, doctors have often prescribed controlling the types of food entering the body to ease the stress of digestion, many diets have been suggested but the pattern that runs through them all is low carbohydrate intake.
While the subject remains controversial, diets such as vegan, vegetarian, ketogenic, glycemic index, low carb, and high fibre diets all involve lowering carbohydrate intake while increasing dietary-fibre. This leads to patients feeling fuller for longer, while needing less insulin to process the sugar and carbohydrates present in the food. These diets have effectively reversed the disease for many sufferers of diabetes and remain the first course of treatment to pre-diabetics.
