Diet (nutrition)

In nutrition, 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. The word diet often implies the use of specific intake of nutrition for health or weight-management reasons (with the two often being related). Although humans are omnivores, each culture and each person holds some food preferences or some food taboos. This may be due to personal tastes or ethical reasons. Individual dietary choices may be more or less healthy.

Complete nutrition requires ingestion and absorption of vitamins, minerals, and food energy in the form of carbohydrates, proteins, and fats. Dietary habits and choices play a significant role in the quality of life, health and longevity.

Religious and cultural dietary choices

Some cultures and religions have restrictions concerning what foods are acceptable in their diet. For example, only Kosher foods are permitted by Judaism, and Halal foods by Islam. Although Buddhists are generally vegetarians, the practice varies and meat-eating may be permitted depending on the sects. In Hinduism, vegetarianism is the ideal. Jains are strictly vegetarian and consumption of roots is not permitted.

Human nutrition

Human nutrition refers to the provision of essential nutrients necessary to support human life and health. Generally, people can survive up to 40 days without food, a period largely depending on the amount of water consumed, stored body fat, muscle mass and genetic factors.

Poor nutrition is a chronic problem often linked to poverty, poor nutrition understanding and practices, and deficient sanitation and food security. Lack of proper nutrition contributes to lower academic performance, lower test scores, and eventually less successful students and a less productive and competitive economy.Malnutrition and its consequences are immense contributors to deaths and disabilities worldwide. Promoting good nutrition helps children grow, promotes human development and advances economic growth and eradication of poverty.

Overview

The human body contains chemical compounds, such as water, carbohydrates (sugar, starch, and fiber), amino acids (in proteins), fatty acids (in lipids), and nucleic acids (DNA and RNA). These compounds consist of elements such as carbon, hydrogen, oxygen, nitrogen, phosphorus, calcium, iron, zinc, magnesium, manganese, and so on. All the chemical compounds and elements contained in the human body occur in various forms and combinations such as hormones, vitamins, phospholipids and hydroxyapatite. These compounds are found in the human body and in the different types of organisms that humans eat.

Last Week Tonight with John Oliver

Last Week Tonight with John Oliver, often abridged as Last Week Tonight, is an American late-night talk and news satire television program airing on Sundays on HBO in the United States and HBO Canada, and on Mondays (originally Tuesdays) on Sky Atlantic in the United Kingdom. The half-hour long show premiered on Sunday, April 27, 2014, and is hosted by comedian John Oliver. Last Week Tonight shares some similarities with Comedy Central's The Daily Show with Jon Stewart, where Oliver was previously featured as a correspondent and fill-in host, as it takes a satirical look at news, politics and current events on a weekly basis.

Oliver has said that he has full creative freedom, including free rein to criticize corporations. His initial contract with HBO was for two years with an option for extension. In February 2015, it was announced that the show has been renewed for two additional seasons of 35 episodes each. Oliver and HBO programming president Michael Lombardo have discussed extending the show from half an hour to a full hour and airing more than once a week after Oliver "gets his feet under him".

Dietary fiber

Dietary fiber or roughage is the indigestible portion of food derived from plants. It has two main components:

Dietary fibers can act by changing the nature of the contents of the gastrointestinal tract and by changing how other nutrients and chemicals are absorbed. Some types of soluble fiber absorb water to become a gelatinous, viscous substance which is fermented by bacteria in the digestive tract. Some types of insoluble fiber have bulking action and are not fermented.Lignin, a major dietary insoluble fiber source, may alter the rate and metabolism of soluble fibers. Other types of insoluble fiber, notably resistant starch, are fully fermented.
