COMPLICATIONS ENCOUNTERED
Most articles written in the 1980’s Limited amount of articles on topic within the
last ten years Several articles weren’t limited to specific
vegetarian articles, but similar diets, such as the lacto-ovo vegetarians, etc.

HYPERTENSION PREVENTION THROUGH VEGETARIANISM
Blood pressure decreases in vegetarian diets high in polyunsaturated fatty acids, which promotes vasodilation and decreases viscosity of blood (Varshney, Bedi, & Bhandari, 2005).
Increased consumption of fruits and vegetables decreases systolic and diastolic blood pressures (Adebawo et al., 2006).
Vegetarians showed to have a lower blood pressure verses non-vegetarians (Appleby, Davey, and Key, 2002).
HOW A VEGETARIAN DIET PREVENTS/ TREATS HYPERTENSION
High vegetable diet can prevent hypertension (Appleby, Davey, and Key, 2002). Soluble fiber can prevent hypertension (Adebawo
et al., 2006). Vegetarians have shown an incidence of
having a lower blood pressure (Elliot et al., 2006).
Non-vegetarians typically have a higher blood pressure than vegetarians (Varshney et al., 2005).
RED MEAT EFFECTS
The higher the consumption of red meat the greater the increase in blood pressure (Tzoulaki et al., 2008).

Eating lean red meat can reduce blood pressure (Hodgson et al., 2006).

LIFESTYLE CHANGES EFFECTING BLOOD PRESSURE
Moderate exercise as well as stress management (Appleby, Davey, and Key, 2002)
The above changes along with a proper diet can lower blood pressure (Slavicek et al., 2008).
A healthy lifestyle can help to prevent hypertension as well as related chronic diseases (Elliot et al, 2006).
HEALTH BENEFITS OF A VEGETARIAN DIET
Vegetarians have a lower death rate from diseases such as, ischemic heart disease and cerebrovascular disease (Appleby et al., 2002).
Important effects of dietary exposures and health concerns are underestimated (Elliot et al, 2006).
Vegetarian diet can decrease systolic and diastolic blood pressures, body mass index, weight, cholesterol, and blood glucose (Slavicek et al., 2008).
CLINICAL IMPLICATIONS
Teach others the importance of vegetables and red lean meats
Promote awareness through informational brochures and flyers
Provide access to appropriate agencies http://www.vegetarian-nutrition.info/ http://www.vegetariannutrition.net/
GAPS AND FUTURE RESEARCH
Physiological reasons of how blood pressure is lowered by vegetarian diets
Up to date qualitative articles Collaborations with cardiovascular doctors
and nutritionists Collaborations with vegetarians and
nutritionists
CONCLUSION
You don’t have to be a vegetarian to maintain a healthy lifestyle/blood pressure
Hypertension can be reduced and prevented Prevent hypertension = prevent other
chronic diseases
