The objective of nutritional epidemiological research is to provide scientific evidence to support an understanding of the role of nutrition on the causes and prevention of ill health. [6] It is important to address the factors that affect food supply, including quality, quantity and balance and the factors that affect food after consumption.
Nutrition studies focus on antinutrients commonly found in food sources and beverages. Antinutrients may take the form of drugs, chemicals that naturally occur in food sources, proteins, or overconsumption of nutrients themselves. Antinutrients may act by binding to vitamins and minerals, preventing their uptake, or inhibiting enzymes.
Foods high in magnesium (an example of a nutrient) Human nutrition deals with the provision of essential nutrients in food that are necessary to support human life and good health. [1] Poor nutrition is a chronic problem often linked to poverty, food security, or a poor understanding of nutritional requirements. [2]
However, as the food supply has evolved, and with the increasing demand for nutritional and related components, it has become more difficult for compilers to rely only on chemical analysis when compiling FCDBs. For example, in the UK the third edition of The Composition of Foods [3] presented data on vitamin content of foods. However, due to ...
The World Health Organization (WHO) issued consultative recommendations regarding nutrient requirements in HIV/AIDS. [6] A generally healthy diet was promoted. For HIV-infected adults, the WHO recommended micronutrient intake comes from a good diet at RDA levels; higher intake of vitamin A, zinc, and iron can produce adverse effects in HIV positive adults, and these were not recommended unless ...
A popular example of drug–food interaction is the effect of grapefruit on the metabolism of drugs. Interactions may occur by simultaneous targeting of receptors , directly or indirectly. For example, both Zolpidem and alcohol affect GABA A receptors , and their simultaneous consumption results in the overstimulation of the receptor, which can ...
Preventive nutrition has been known about for a long time. The philosopher Hippocrates (460-377 BC) believed that nutrition had a significant impact on maintaining health and that the best way to prevent diseases was to "let food be your medicine and medicine be your food.” [4] Meyer-Abich (2005) also believed that nutrition was foundational to a healthy life.

Nutritional genomics, also known as nutrigenomics, is a science studying the relationship between human genome, human nutrition and health. People in the field work toward developing an understanding of how the whole body responds to a food via systems biology, as well as single gene/single food compound relationships.
