Presentation title:Plant-based Rx: Integrating Nutrition Conversations into Clinical Practice
Course description: Research continues to show that a plant-based diet helps people lose weight, lower blood pressure, improve cholesterol, stabilize blood sugar, reduce the risk of cancer, prevent Alzheimer’s Disease, and more.

Of those that do have the discussion, most simply advocate or prescribe change, leaving patients to figure out how to make the transition.

Course objectives: At the end of the presentation, the learner will:
1. Discuss the latest research on the relationship between diet, prevention, and health.
2. Relate the information-motivation-strategy model to dietary change.
3. Examine the most common questions asked about plant-based eating.

Course title: The Far-Reaching Grasp of High Blood Pressure
Course description: High blood pressure is affecting progressively more Americans, with the numbers affected steadily increasing over the lifespan. With prevalence rates approaching 75% among the U.S. senior population, the public health impact of hypertension continues to increase as our population ages. In this introductory session, participants will learn salient aspects regarding the epidemiology of hypertension which make a case for all health professionals being aware of strategies to help combat this silent killer. This session will also look at reasons for the poor compliance with current blood pressure approaches (only about 50% of American hypertensives have their BP well controlled) and will provide a framework for utilizing non-drug strategies in clinical and community-based encounters.
Course objectives: At the end of the session participants will be able to:
1. Articulate at least four fundamental aspects of hypertension epidemiology in the United States
2. List five common pitfalls in blood pressure assessment
3. Provide an explanation for the relatively poor compliance with blood pressure management approaches
4. Describe a ten-step approach to controlling blood pressure utilizing non-pharmacological strategies
