Reducing heart disease through the vegetarian diet using primary prevention.

PURPOSE: To evaluate research on the vegetarian diet for its safety, effectiveness in reducing heart disease, special considerations, contraindications, and its association with decreased cardiovascular disease risk.

DATA SOURCES: Selected research and evidence-based dietary guidelines found by searching CINAHL, PubMed, Ovid databases, and the World Wide Web.

CONCLUSIONS

A carefully planned vegetarian diet with adequate supplementation may be effective for primary prevention of heart disease. The vegetarian diet is cost effective, safe, and relatively easy to implement.

IMPLICATIONS FOR PRACTICE: Improved dietary choices can help improve many chronic conditions. Guidelines for proper nutrition within a vegetarian lifestyle are readily accessible to patients and professionals alike. Referral to a dietitian is an appropriate option in primary care settings.
