The study of nutrition focuses on how food and drink influence our bodies, particularly the vital nutrients required to maintain human health. Apart from analyzing how nutrients in food produce energy or are transformed into human tissues, it also examines the physiological and biochemical processes involved in nutrient consumption. These nutrients include carbohydrates, lipids, fiber, minerals, proteins, vitamins, and water which are the source of energy for our bodies. Every dietician says that getting the proper quantity of nutrients from meals in the right proportions constitutes good nutrition. Examining illnesses that might come from malnutrition and the role that food plays in the emergence of chronic disease are key aspects of nutrition. A nutritionist assesses the nutritional aspect through important nutrition tests like vitamin tests, mineral tests, amino acid tests, and nutritional genomics tests.
