At a time when 20% of people in the US go to bed hungry each night and almost 50% of the world's population is malnourished, choosing to eat more plant-based foods and less red meat is better for all of us-ourselves, our loved ones, and our planet.

I've found that if I tell somebody 'Eat this and don't do that,' it's not only not helpful, it's counterproductive because even more than being healthy, we want to feel free and in control, and as soon as somebody tells us to do something, there's a tendency to do just the opposite.

I grew up in Texas, eating meat five times a day, and I liked meat. But I began being a vegetarian when I was 19 because I found that I felt better.
