Nutrigenomics is the study of how nutrients interact with genes to influence health and disease. This emerging field explores the role of diet in gene expression and how individual genetic variations can affect nutrient metabolism. Nutrigenomics aims to develop personalized nutrition plans based on a person’s genetic makeup to optimize health and prevent or treat diseases. For instance, people with certain genetic mutations may have an increased risk of developing conditions like heart disease or diabetes, but tailored dietary interventions can mitigate these risks. Research in nutrigenomics has shown that dietary components, such as vitamins, minerals, and phytochemicals, can activate or deactivate genes that are involved in inflammation, oxidative stress, and metabolism. As the field grows, nutrigenomics has the potential to revolutionize healthcare by providing more precise and effective dietary recommendations based on an individual’s genetic profile.
