Physician's advice affects adoption of desirable dietary behaviors

Due to the prevalence of and economic costs associated with poor dietary behaviors, the purpose of our research is to investigate the relationship between receipt of physician's dietary advice and the individual's tendency to adopt the desirable dietary behavior. Using a trivariate probit model, we find that physician's advice has dramatic positive effects on the probability of both eating fewer high fat and high cholesterol foods and on eating more fruits and vegetables to reduce risk of developing heart disease or stroke.
