The development of personalised diets tailored to our genes will help us to both maintain health and relieve disease. Current dietary guidelines provide a "one-size fits all" approach that ignores the genetic differences between individuals. However, studies of the interaction of genes and diet are now coming of age as a result of the sequencing of the human, mouse and rat genomes, improved understanding of the mechanisms that underlie chronic inflammation, and new understandings of the ways in which macronutrients and micronutrients interact with our genetic make-up.

Macronutrients and micronutrients influence the metabolic programming of cells and help control homeostasis. But equally important is how any one person's body will use and respond to nutrients, which is driven at least in part by their genetic make- up.

Prof Bruce Ames of the University of California, Berkeley, says that micronutrient deficiencies are widespread and may be a major preventable cause of the diseases of ageing. Ames" theory states diat the degenerative diseases that accompany ageing, such as immune dysfunction, cancer, cognitive decline....read the whole story
