ABC of Nutrition

ABC of Nutrition

Walter B. Gratzer is a British biophysical chemist. According to Walter Gratzer, the study of nutrition probably began during the 6th century BC. The first recorded dietary advice, carved into a Babylonian stone tablet in about 2500 BC, cautioned those with pain inside to avoid eating onions for three days. Scurvy, later found to be a vitamin C deficiency, was first described in 1500 BC in the Ebers Papyrus. Around 1770, Antoine Lavoisier discovered the details of metabolism, demonstrating that the oxidation of food is the source of body heat. Human nutrition is very important part of science, experiment of that start from the past.

Nutrition is the science that interprets the interaction of nutrients and other substances in food in relation to maintenance, growth, reproduction, health and disease of an organism. It includes food intake, absorption, assimilation, biosynthesis, catabolism and excretion. Nutritional science studies how the body breaks food down (catabolism) and how it repairs and creates cells and tissue (anabolism). Catabolism and anabolism combined can also be referred to as metabolism. Nutritional science also examines how the body responds to food.

Nutrition, nourishment, or aliment, is the supply of materials - food - required by organisms and cells to stay alive. In science and human medicine, nutrition is the science or practice of consuming and utilizing foods. In hospitals, nutrition may refer to the food requirements of patients, including nutritional solutions delivered via an IV (intravenous) or IG (intragastric tube).

Dietetics is the practice of integrating biochemical, physiological, social, and managerial concepts into the science of nutrition to achieve a healthy lifestyle. A degree in dietetics offers challenging and rewarding employment opportunities working in hospitals, long term care facilities, public health agencies, food industry, research labs and more. Whether administering medical nutrition therapy in health care setting or directing food service operation.

A dietitian or dietician is an expert in dietetics; that is, human nutrition and the regulation of diet. A dietitian alters their patient's nutrition based upon their medical condition and individual needs. Dietitians are regulated healthcare professionals licensed to assess, diagnose, and treat nutritional problems.
