Nutritional Science

Nutritional science is the study of how an organism is nourished, and includes the study of Nutrition and metabolism. Nutritional science shelters a wide spectrum of disciplines. Nutrients must be obtained from diet, since the human body does not synthesize them and are used to generate energy, notice and respond to environmental surroundings, move, excrete wastes, respire. Healthy food habit is becoming ever more of a science, with new research showing us which foods may decrease our risk of disease, and which are progressively pointed to as the culprits behind ill health. Researchers are looking to better recognise how nutrients work in our bodies, with studies that investigate the diets of people with heart disease, cancer, and other diseases, along with research aimed at helping people to lose weight, or maintain weight loss. There are various classes of nutrients such as carbohydrates, lipids, proteins, water, vitamins, and minerals which are required for the body to function and maintain overall health.
