Knowledge of the basic nutritional needs of human beings is based on decades of sound scientific research. The basic daily requirement for protein and fat is generally unrelated to sex, age and weight and is the same for healthy as well as unwell individuals. Quantities however may vary depending on the degree of absorption in the intestines or if metabolic disorders exist. In addition to this there is a need for energy, preferably from carbohydrates that will be absorbed more slowly in the intestines, thus causing moderate increases in blood sugar and insulin levels. Quick absorbing carbohydrates such as cane sugar, wheat, starch and the like, add energy for sure, but are not included in the basic physiological needs. On the contrary, a diet including higher quantities of these may lead to health problems and illness and increased fat disposition in the body. Slow carbohydrates are therefore preferable as a source of energy.
Recent research has also shown that it is not just the chemical structure of carbohydrates that affects the blood sugar curve, i.e. the glycaemic index (GI), but also factors like the dietary structure, fat and protein content (type, amount and balance) and dietary fibre. One important aspect of nutrition is its impact on our brain functions. Research has shown that concentration levels and problem solving abilities (as per accepted test models) will both improve given the right proteins and fats in combination with slow carbohydrates, which will result in a flat blood sugar curve.
