Scientific studies have documented the benefits of a personalized nutrition plan compared to more generic diets. Nielsen and El-Sohemy have recently shown that nutritional advice developed on genetic profiles is accepted and understood more effectively than generic recommendations. People who receive DNA-based advice improve their diet to a greater extent than those who receive standard dietary advice. They're also the ones who need to change it the most. Personalized dietary information not only increases compliance but also better supports the long-term health of patients. (Frayling et al. 2007). Finally, Arkadianos and colleagues compared two groups of people: one subjected to a diet based on their genetic profile, the other to a traditional diet. The team found out that subjects who received DNA-based dietary advice showed improvements to their diets after 3 months, and the changes became even more apparent after 12 months. The group that followed the genetic diet managed to achieve the objectives in terms of weight loss and ideal weight maintenance over time. In addition, blood tests showed that their sugar levels had improved significantly (Daiva E. Nielsen, Ahmed El-Sohemyon, Disclosure of Genetic Information and Change in Dietary Intake: A Randomized Controlled Trial, PLoS One, 2013).
