ABSTRACT
Nutrition is a modifiable important element that can influence human health by interacting with the genome as well as the epigenome. Specific genetic polymorphisms can influence how the body reacts to nutritional requirements and food material, and the diet can modulate gene expression as well. We’ve discussed regarding how proper nutrition is vital for staying healthy in this chapter. The chapter also emphasises which foods should be ingested and which should be avoided in order to avoid their contact with our genes, which might produce gene variation, which can further lead to numerous health problems. Furthermore, how can diversity in gene expression be passed down from generation to generation? The chapter also discusses how genetic variations can cause a variety of ailments and what dietary changes are required in such circumstances; how direct-to-consumer gene testing can be used to test gene variation; and how tailored nutrition uses genetic, phenotypic, clinical, dietary, and other data to deliver more precise and effective personalized healthy eating advice and to drive appropriate dietary adjustments in order to maintain and improve health. This chapter studies relationships between epigenetic variables and eating disorders (EDs) and involves investigation on how gene expression and epigenetic programming can explain for gene–environment interactions in EDs. Finally, a case study 178is explained on how gene expression profiles are different with different dietary patterns, which, in turn, can result in long-term illness.
