"Is a plant-based diet extreme?... Over 600,000 Americans each year will choose to have their chest cut open, instead of changing what they eat... that's extreme."On this week's episode of the Eat Green Make Green Podcast, I address the most common questions I receive from listeners with regard to living a plant-based or vegan lifestyle. The questions I answer are:Where do you get your protein?Aren't I going to be deficient in things like iron?What the hell do you eat?Isn't eating plant-based expensive?It's impossible to stick with it while traveling right?My meat-eating, stogie-smoking, bud light-drinking grandpa is alive and kicking at 90, how do you explain that?Don't you think a plant-based diet is a little extreme?How could I ever give up burgers and cheese?
