Vegan or not, gluten-free or not, Erin McKenna's donuts are the best I've had in 20 years, without exception.

50-100 years from now we are all going to be eating a plant based diet. Whether that happens through a catastrophe or a peaceful sustainable life giving way is based on whether we make the right choices now and how we fight in this struggle together.

I think people at least now, as opposed to ten-15-20 years ago, kind of get it, what is the bad food. I think, before, there was a time when they didn't even get it that processed food was hurting them. Now, I think they get that, but the big enemies to switching over to good food are convenience.

We need real farmers who grow real food, and the will to reform a broken food system. And for that, we need not only to celebrate farmers, but also to advocate for them.

Keeping some calorie-dense food in your diet-whether it is meat, pasta, beer, or cake-allows you to reach satiety more quickly and easily. And this will keep you from feeling deprived.

If price spikes don't change eating habits, perhaps the combination of deforestation, pollution, climate change, starvation, heart disease and animal cruelty will gradually encourage the simple daily act of eating more plants and fewer animals.

Our demand for meat, dairy and refined carbohydrates - the world consumes one billion cans or bottles of Coke a day - our demand for these things, not our need, our want - drives us to consume way more calories than are good for us.
