The idea behind nutrigenomics is to support people in making long-lasting dietary behavior changes that are good for their health. The goal of nutrigenomics is to clarify how diet affects human health.
The two main causes of an increase in chronic diseases among patients are unhealthy lifestyle trends and dietary decisions. Additionally, a greater emphasis on health management factors at later stages of ageing has resulted from an increase in the geriatric population and an increase in life expectancy. An individual can achieve a long-lasting, healthful change in eating habits with the aid of nutrigenomics. The bioactive food ingredients may interact with genes, which would then have an impact on how the body works. Nutrigenomics allows for the study of metabolic inborn errors that can be treated and controlled through diet.
The understanding of genetic associations has advanced over time, particularly through genome-wide association studies, which have revealed a significant role for genes in human ageing and age-related diseases (ARD). Conditions like obesity have a strong connection to nutrition-gene interaction and may be controlled to combat the rising prevalence of obesity in the world.
The development of omics technology has provided access to
- deliver biomarkers for wellbeing and comfort
- reveal early disease indicators
- help distinguish between dietary responders
- non-responders by identifying bioactive food components.
The interaction between a gene and a nutrient alters genes linked to metabolism, which in turn affects the quantity and activities of the enzymes produced to feed the body. This gene-nutrient interaction has the power to change the molecular phenotypes, including disease expression. The interaction between genes and diet is frequently influenced by a person's environment, biology, and genetic makeup.
The global nutrigenomics market was estimated to be worth $903.0 million in 2020, and BIS Research's most recent market intelligence indicates that it is projected to increase at a CAGR of 17.26% from 2021 to 2031.
Since its inception, the global market for nutrigenomics has grown, and as a result, so have its applications. Nutrigenomics can currently be applied in the following fields.
Women's health
In the context of nutrigenomics studies, women's health is a very important topic. Lack of vaginal Lactobacillus species puts women at high risk for serious, expensive reproductive diseases as well as unfavourable obstetric outcomes. The nutrigenomics market is growing as a result of the use of potential prebiotics in addressing the recovery of women's health. Prebiotics will not be used in prevention and treatment recommendations for women's health for quite some time, though.
Digestive health
A highly complex and varied microbial community, with a 10:1 ratio of microbial to human cells, resides in the human gastrointestinal tract. Malnutrition, diabetes, chronic inflammatory bowel diseases (including ulcerative colitis and Crohn's Disease), and pathological diseases are all largely caused by disruption of the gut microbiota.
Immune health
The immune system in the human body is made up of a very complex network of elements that can adapt and react to a variety of threats. Innate and adaptive immunity mechanisms in the body interact with one another to form the partnership between the immune system and the microbiota. Any change in the microbiota's functioning brought on by dietary modifications, the use of antibiotics, and the eradication of particular microbial species can make microbes more of a liability than an ally.
Others
Nutrigenomics also has a significant impact on the health of the skin, bones, and teeth.
