Food supplements

From Wikipedia, the free encyclopedia

Jump to: navigation, search

A food supplement is, typically, a nutrient added to a foodstuff which would otherwise not contain that nutrient. In general, the term is restricted to those additives which are deemed to be positive for health, growth or well-being.

Introduction

Several ranges of food supplements are recognised:

  • additives which repair a deficit to "normal" levels
  • additives which appear to enhance a food
  • supplements taken in addition to the normal diet

Many physicians today disagree with the premise that foodstuffs need supplementation, but accept that - for example - added calcium may provide benefit, or that adding folic acid may correct a nutritional deficiency especially in pregnant women.

On a more controversial level, but well founded in scientific basis, is the science of using foods and food supplements to achieve a defined health goal. A common example of this use of food supplements is the extent to which body builders will use amino acid mixtures, vitamins and phytochemicals to enhance natural hormone production, increase muscle and reduce fat.

Moving on from this reasonably accepted usage, there is increasing evidence for the use of food supplements in established medical conditions. This nutritional supplementation using foods as medicine (nutraceuticals) has been effectively used in treating disorders affecting the immune system up to and including cancers. This goes beyond the definition of "food supplement", but should be included for the sake of completeness.

Aspects of health

Physical health

Physical fitness is good bodily health, and is the result of regular exercise, proper diet and nutrition, and proper rest for physical recovery.
A strong indicator of the health of populations is height, which is generally increased by improving nutrition and health care, and is also influenced by the standard of living and quality of life. Genetics is also a major factor in people's height. The study of human growth, its regulators, and its implications is known as Auxology.

Mental health


Mental health refers to a human individual's emotional and psychological well-being. Merriam-Webster defines mental health as "A state of emotional and psychological well-being in which an individual is able to use his or her cognitive and emotional capabilities, function in society, and meet the ordinary demands of everyday life."

According to the World Health Organization, there is no one "official" definition of mental health. Cultural differences, subjective assessments, and competing professional theories all affect how "mental health" is defined. In general, most experts agree that "mental health" and "mental illness" are not opposites. In other words, the absence of a recognized mental disorder is not necessarily an indicator of mental health.

One way to think about mental health is by looking at how effectively and successfully a person functions. Feeling capable and competent; being able to handle normal levels of stress, maintain satisfying relationships, and lead an independent life; and being able to "bounce back," or recover from difficult situations, are all signs of mental health.

Encompassing your emotional, social, and—most importantly—your mental well-being; All these aspects—emotional, physical, and social—must function together to achieve overall health.
