These mechanisms have not been totally discounted and probably play some role in short-term control of eating. 1. On reaching the arcuate nucleus in the hypothalamus, it stimulates the release of neuropeptide Y (NPY), which is a potent stimulant of food intake. These hormones act both locally and centrally to inhibit the release of ghrelin, slow down stomach emptying and stimulate hunger-reducing neurones in the hypothalamus. It is believed to potentiate the satiating effects of CCK. Insulin also has a central effect to reduce the size of the meal consumed.

This contributes to satiety and promotes dental health. As NSP moves down through the SI, divalent cations such as calcium, zinc and iron may bind to its surface, reducing their availability for absorption. The multiplication of the bacterial flora increases bulk and water content of the stools. This stimulates peristalsis, increases the speed of movement of the colon contents, reduces transit time through the gastrointestinal tract and contributes to the overall laxation effect. The wide range of CHOs consumed in the diet not only provides the body with glucose to maintain blood levels of this essential nutrient for brain and nervous system function but also with a food source for colonic bacteria, which enables a population of beneficial microorganisms to be maintained in the colon, thereby contributing to colon health.

Additional roles for vitamin D in cellular metabolism have also been described. 1 Examples of nutrition-related diseases predominantly associated with single dietary factors. Excessive intake of vitamin A has been shown to cause fetal malformations in early pregnancy. In the early 1950s, infants given excessive amounts of formula milk and cod liver oil supplements containing large amounts of vitamin D developed hypercalcaemia. Once the link between a nutrient and a particular disease was established, public health measures were introduced to prevent or treat the disease, for example, prescribing folic acid to pregnant women for prevention of neural tube defects (NTD).
