  Purpose
The aim of this study is to see if the investigators can encourage people to eat more fruits, vegetables and whole grains and drink less pop by giving them advice about their diet, or by providing them with samples of different kinds of foods. The investigators are interested in the effect this has on reducing the risk of chronic disease. The investigators will also be investigating how certain genes affect the choices people make about the foods they eat.
