The focus of the conference was connecting how epigenetics (cellular and physiological phenotypic trait variations that are caused by
external or environmental
factors that switch genes on and off and affect how cells read genes instead of being caused by changes in the DNA sequence — in other words nutrition and
lifestyle choices) impact whether or not an individual actually develops a specific health issue even though they have a SNP mutation.
Many
factors contribute to obesity, including: age, sex, reproductive status, the presence of hormonal abnormalities, genetic predisposition, activity level,
external influences on food intake, diet composition and palatability, and environment and
lifestyle.
