It is now commonly believed in the medical world that nutritional products are a vital part of a healthy eating programme. It has become increasingly difficult to obtain optimum levels of nutrients from food intake alone, especially anti-oxidants and minerals. This is mainly due to an increased demand by our bodies for these anti-oxidants and also as a result of depletion of nutrients in the food that we eat. Vitamins and Minerals The role of anti-oxidants in the body is to support healthy immune functions and to eliminate harmful free radicals. Free radicals are created as a waste product from chemical processes within the body (specifically respiration and digestion) and are highly volatile particles, which damage human cells. Over a period of time, constant attacking of our cells by free radicals can lead to the development of degenerative diseases and conditions. Therefore, an advanced intake of vitamins and minerals can help to reduce free radical damage and help in the fight against degenerative conditions. Minerals also have many unique funtions within our bodies, acting on cells, tissues and organs. All of our bodily processes depend on minerals to initiate the enzymes, which perform those bodily functions. Our demand for vitamins and minerals is now larger than ever due to the excessively toxic environment that we live in. Environmental pollution, toxic chemicals in the water supply and enhanced levels of radiation from the sun support our increased demand for anti-oxidants. In addition, stress, lack of sleep and bad food choices will increase free radical occurance. The food choices that we make today are commonly devoid of the important antioxidants and minerals that we require for our bodies to function properly. Low Glycemic Foods Diseases such as Obesity and Diabetes are commonly caused by poor food selection. Typically, high calorific foods encourage Obesity, but the role of high glycemic foods cannot be overlooked. High glycemic foods (high GI) are foods that sugar rapidly once inside your body, such as sweets, cakes and refined carbohydrates (white bread, white pasta, etc). These kinds of foods cause rapid increases in blood sugar levels. As blood sugar levels drop, you will experiences a drop in energy and urges for high glycemic foods (carbohydrate cravings). If you regularly give in to your cravings, this will increase your calorific intake. Over a period of time your body becomes less able to regulate after dramatic increases in blood sugar levels, which can in turn lead to the onset of type 2 Diabetes. If you have weight loss plans or concerns about diabetes, then low glycemic, nutritionally balanced meal replacements and healthy snacks can offer you assistance.
