What you eat can effect how well your genes work. By doing a simple cheek swab it is possible to test if you are at risk of health conditions such as cancer, heart disease or diabetes. It is also possible to determine if you are sensitive to certain foods because of intolerances to lactose or gluten. DNA tests enable supplementation to be targeted and the dietary advice to be tailored to the specific genetic results. While the DNA test itself involves a 15 minute consultation, the report back session is approximately an hour.
