Hypertension is the cause of about 7.5 million deaths per year, globally. More than 40% of African Americans are diagnosed with hypertension. The aim of this study was to examine the effects of walnut consumption on blood pressure in a small convenience sample of African Americans in Mississippi. Fifty subjects participated in the study. Blood pressure was measured once a week for three weeks prior to the initiation of the intervention for a baseline data of the subjects’ normal blood pressure. During the 6-week intervention, the participants consumed a package of walnuts, daily. Blood pressure was measured weekly. The results of the study indicate that there was no significant impact on systolic pressure (MD: 1.61; CI: -.979, 4.20; p=.217) or diastolic pressure (MD: .806; CI: -.905, 2.51; p=.349). Future studies should be performed with more participants, higher dose of walnuts, and a longer trial period.
