Brief Summary

Food is emerging as the new medicine. There has been growing evidence of the beneficial effects of foods, including nuts on human health. Modulation of both glucose and insulin are at the heart of reducing the risk of cardiovascular and other metabolic diseases. The contribution that nuts have on human health has been studied extensively and it is well established that the consumption of nuts revealed improvements in both blood glucose profile and reduced the risk of coronary heart diseases. Nuts, such as almonds, are nutrient-dense foods that are particularly rich in a-tocopherol. They are excellent sources of protein (\~25% of energy) and fibre, low in saturated fatty acid content (4-6%) and high in monounsaturated fatty acids. They also contain significant amounts of essential micronutrients such as folate (B vitamin) and polyphenols. Recently, strong interests on the health effects of nuts improving metabolic syndrome and controlling diabetes has been reported. Preliminary studies have indicated that the inclusion of nuts in the diets of individuals with diabetes and/or metabolic syndrome may improve postprandial glycaemic response, and lipid metabolism in the long run.
