Nutrition (also called nourishment or aliment) is the provision, to cells The cell is the basic structural and functional unit of all known living organisms. It is the smallest unit of life that is classified as a living thing, and is often called the building block of life. Some organisms, such as most bacteria, are unicellular . Other organisms, such as humans, are multicellular. (Humans have an estimated 100 trillion and organisms The term "organism" first appeared in the English language in 1701 and took on its current definition by 1834 (Oxford English Dictionary), of the materials necessary (in the form of food) to support life Life is a characteristic that distinguishes objects that have self-sustaining biological processes from those that do not —either because such functions have ceased (death), or else because they lack such functions and are classified as "inanimate.". Many common health problems can be prevented or alleviated with a healthy diet A healthy diet is one that helps maintain or improve health. It is important for the prevention of many chronic health risks such as: obesity, heart disease, diabetes, and cancer.
The diet In nutrition, the diet is the sum of food consumed by a person or other organism. Dietary habits are the habitual decisions an individual or culture makes when choosing what foods to eat. Although humans are omnivores, each culture holds some food preferences and some food taboos. Individual dietary choices may be more or less healthful. Proper of an organism is what it eats, and is largely determined by the perceived palatability Palatability is the hedonic reward provided by foods or fluids that are agreeable to the "palate" in regard to the homeostatic satisfaction of nutritional, water, or energy needs. The palatability of a food or fluid, unlike its flavor or taste, varies with the state of an individual: it is lower after consumption and higher when deprived of foods. Dietitians A dietitian or dietician is an expert in food and nutrition are health professionals A health care provider or health professional is an organization or person who delivers proper health care in a systematic way professionally to any individual in need of health care services who specialize in human nutrition, meal planning, economics, and preparation. They are trained to provide safe, evidence-based dietary advice and management to individuals (in health and disease), as well as to institutions.
A poor diet can have an injurious impact on health, causing deficiency diseases such as scurvy Scurvy is a disease resulting from a deficiency of vitamin C, which is required for the synthesis of collagen in humans. The chemical name for vitamin C, ascorbic acid, is derived from the Latin name of scurvy, scorbutus, which also provides the adjective scorbutic . Scurvy leads to the formation of spots on the skin, spongy gums, and bleeding, beriberi Beriberi is a nervous system ailment caused by a deficiency of thiamine (vitamin B1) in the diet. Thiamine is involved in the breakdown of energy molecules such as glucose and is also found on the membranes of neurons. Symptoms of beriberi include severe lethargy and fatigue, together with complications affecting the cardiovascular, nervous,, and kwashiorkor Kwashiorkor is an acute form of childhood protein-energy malnutrition characterized by edema, irritability, anorexia, ulcerating dermatoses, and an enlarged liver with fatty infiltrates. Kwashiorkor is a low serum albumin of dietary origin, marked by edema. Kwashiorkor was thought to be caused by insufficient protein consumption but with; health-threatening conditions like obesity Obesity is a medical condition in which excess body fat has accumulated to the extent that it may have an adverse effect on health, leading to reduced life expectancy and/or increased health problems. Body mass index , a measurement which compares weight and height, defines people as overweight (pre-obese) when their BMI is between 25 kg/m2 and 30 and metabolic syndrome Metabolic syndrome is a combination of medical disorders that increase the risk of developing cardiovascular disease and diabetes. It affects one in five people, and prevalence increases with age. Some studies estimate the prevalence in the USA to be up to 25% of the population, and such common chronic systemic diseases as cardiovascular disease Cardiovascular disease or cardiovascular diseases is the class of diseases that involve the heart or blood vessels . While the term technically refers to any disease that affects the cardiovascular system (as used in MeSH), it is usually used to refer to those related to atherosclerosis (arterial disease). These conditions have similar causes,, diabetes Diabetes mellitus —often referred to as diabetes—is a condition in which the body either does not produce enough, or does not properly respond to, insulin, a hormone produced in the pancreas. Insulin enables cells to absorb glucose in order to turn it into energy. This causes glucose to accumulate in the blood (hyperglycemia), leading to, and osteoporosis Osteoporosis is a disease of bone that leads to an increased risk of fracture. In osteoporosis the bone mineral density is reduced, bone microarchitecture is disrupted, and the amount and variety of proteins in bone is altered. Osteoporosis is defined by the World Health Organization (WHO) in women as a bone mineral density 2.5 standard deviations.
