Tailoring drugs & diet to your genes? It's already happening.

Now that genetic testing is readily available expect more medicines, and even diet and exercise to be tailored to your gene types. In his latest book, evolutionary biologist, family doctor, surgeon and academic Dr Sharad Paul looks at how environments shape our genes; how genes affect the body's response to prescription drugs; and how we should eat according to our individual genetic codes. In conjunction with the book, The Genetics of Health, Dr Paul has developed a DNA saliva test to determine how genes can influence stress levels, nutrient and mineral metabolism, and even sports preferences.
