DEAR DOCTOR K: I'm trying to shift to a more plant-based diet and have added more fruits and vegetables to my meals and snacks. What's the next step?
DEAR READER: Congratulations! You've already made some healthy changes to your diet. Evidence continues to mount that a plant-based diet -- rich in fruits, vegetables, whole grains and healthy plant oils -- may help reduce the risk of many health concerns, including heart disease, stroke, diabetes and cancer. Adding fresh fruits and vegetables, as you've done, is a great first step. The next step is to incorporate more nuts, seeds and legumes into your meals and snacks.
