Chewing gum can burn approximately 3 to 11 calories per hour, a minimal metabolic boost that depends significantly on the intensity and speed of chewing. This means that while the answer to how much energy does chewing gum use is more than zero, the effect is often overstated as a major weight-loss tactic.

Every physiological process in the human body, from metabolism to digestion, is powered by intricate chemical reactions, confirming that yes, nutrition and dietetics have chemistry at their core. This foundational science explains how we break down food, absorb nutrients, and utilize energy.

First established in 1928, *The Journal of Nutrition* is a highly respected publication, with a peer-reviewed process managed by the American Society for Nutrition and published by Elsevier. This makes its reliability strong, though a critical evaluation of its standards and processes reveals the depth of its credibility within the field.

For centuries, fish liver oil was a folk remedy, especially for conditions like rickets, but its true biological power was unknown. So, what vitamin was isolated from fish liver oil in 1917? The scientific breakthrough of isolating this specific nutrient represented a monumental step forward in understanding human health and diet.

The University of Alabama offers a 30-credit-hour Master of Science in Human Nutrition, designed to provide professionals with advanced knowledge and research skills in the field of dietetics. This program, housed within the Department of Human Nutrition and Hospitality Management, caters to various career goals, including advanced practice and doctoral studies.

The Journal of Nutrition, established in 1928, is a highly respected and long-standing publication in the field of nutritional science. A five-year term for its editor-in-chief was set to begin on January 1, 2024. A search conducted in late 2022 by the American Society for Nutrition (ASN), which publishes the journal, sought a new leader to guide its editorial vision. The editor-in-chief is a key position that directs the scientific content and overall strategy of the publication, influencing the direction of nutrition research.

The term "DV for fiber" presents a significant confusion, stemming from two vastly different scientific and consumer contexts. While many might search for how to calculate nutritional Daily Value (%DV) for dietary fiber on a food label, others, in a mistaken query, might combine the aerospace concept of Delta-V (Δv) with the unrelated term "fiber". This article clarifies both interpretations to resolve this common ambiguity.

Over 50% of dietary assessment studies globally rely on some form of self-reported dietary intake data, highlighting the critical role of these methods. This article explores what is the prospective method of dietary assessment, detailing how this forward-looking approach captures real-time food and beverage consumption for higher accuracy.

Extensive studies in rodents with melanin-concentrating hormone (MCH) have demonstrated that this neuropeptide is a potent orexigen, meaning it stimulates appetite. Located primarily in the brain's feeding center, MCH plays a critical role in regulating food intake and contributing to overall body weight gain in mammals.

According to the World Health Organization, robust national nutrition surveillance is crucial for developing effective health policies. A core component of this surveillance is understanding the objectives of a dietary survey, which provides the critical data needed to assess a population's nutritional status and inform strategic public health decisions.
