CONCLUSION VA Beach Diets Study ➢ Healthy and lifestyle are critical for preventing hypertension. ➢ In our study, all diets were associated with statistically significant reductions An Investigation of Plant-Based, Mediterranean, in blood pressure for all participants ➢ The Vegan diet proved to be the most effective at reducing LDL and total , and Dash Diets Study cholesterol ➢ No significant improvements in glycemic control were seen for any diet group Sophie Talreja1, Alex Talreja2, Hyeon Choi, MD3, Deepak Talreja, MD3 1.
