Food energy

Food energy is energy that animals (including humans) derive from their food, through the process of cellular respiration, the process of joining oxygen with the molecules of food (aerobic respiration) or of reorganizing the atoms within the molecules for anaerobic respiration.

Humans and other animals need a minimum intake of food energy to sustain their metabolism and drive their muscles. Foods are composed chiefly of carbohydrates, fats, proteins, water, vitamins, and minerals. Carbohydrates, fats, proteins, and water represent virtually all the weight of food, with vitamins and minerals making up only a small percentage of the weight. Carbohydrates, fats, and proteins comprise ninety percent of the dry weight of foods. Food energy is derived from carbohydrates, fats and proteins as well as organic acids, polyols, and ethanol present in the diet. Some diet components that provide little or no food energy, such as water, minerals, vitamins and fiber, may still be necessary to health and survival for other reasons. Water contains very stable chemical bonds and so cannot be oxidized to provide energy. Vitamins and minerals are present in very small amounts (in milli- or micrograms) and also cannot be used for energy. Fiber, a type of carbohydrate, cannot be completely digested by the human body. Ruminants can extract food energy from the respiration of cellulose thanks to bacteria in their rumens.

The freshman 15 is an expression commonly used in the United States that refers to an amount (somewhat arbitrarily set at 15 pounds) of weight often gained during a female student's first year at college. In Australia and New Zealand it is sometimes referred to as First Year Fatties, Fresher Spread, or Fresher Five, the latter referring to a five-kilogram gain.

The purported causes of this weight gain are increased alcohol intake and the consumption of fat and carbohydrate-rich cafeteria-style food and fast food in university dormitories. Many dining halls in American universities are all-you-can-eat style and offer copious dessert choices. In addition, lack of sleep may lead to overeating and weight gain, because it lowers the level of leptin. Other causes include malnutrition, stress, and decreased levels of exercise. All of these factors can affect each person in a different way. Studies confirm many of these causes. Colleges and universities have recently been cracking down on this common problem and are trying to educate people on how to prevent it. This problem has grown so much that students are focusing on how to stop the freshman 15 before it happens.

Diet plays an important role in the genesis of obesity. Personal choices, advertising, social customs and cultural influences, as well as food availability and pricing all play a role in determining what and how much an individual eats.

Hospitality is the relationship between the guest and the host, or the act or practice of being hospitable. This includes the reception and entertainment of guests, visitors, or strangers.

In journalism, a human interest story is a feature story that discusses a person or people in an emotional way. It presents people and their problems, concerns, or achievements in a way that brings about interest, sympathy or motivation in the reader or viewer.

Human interest stories may be "the story behind the story" about an event, organization, or otherwise faceless historical happening, such as about the life of an individual soldier during wartime, an interview with a survivor of a natural disaster, a random act of kindness or profile of someone known for a career achievement.
