Given that it takes up to 16 pounds of grain to produce one pound of meat, I think we can also go a long way toward ending hunger and saving the environment as well.

Within an hour I can be at the ocean, the forest, the mountains in San Francisco...But really, I fell in love with the city the first time I came out here in 2003. In addition to the natural beauty, this is ground zero for the food justice movement.

I think that the agriculture system in general is rooted in racism - consider that historically black labor on plantations was the backbone of the economy. These workers didn't reap the benefit of that system.

Food historian Jessica B. Harris says African American cuisine is simply what black people ate. When I think about what my family ate, we ate what people think of as soul food on special occasions, on holidays, but our typical diet was leafy greens and nutrients and tubers - food that was as fresh as being harvested right before our meal. Whatever was in season, that's what we were eating. It was being harvested right from our backyard.

In restaurants across America we see Latino workers in the kitchen who are being paid substandard wages. The saddest thing to me is that if we think about these workers, these are the people with the least access to good food. Yet they're often suffering from the highest rates of obesity and diet-related illnesses.

In terms of addressing some of the most impacted communities and historically excluded communities - often of color, often low income - there is this adage in specifically African American communities that on every corner in low income neighborhoods you'll find a liquor store.

In fact, I don't advocate any particular diet for anyone. I think that's a very personal decision that people have to make. I will say this, however: There are more and more studies in terms of the health benefits of veganism; there are more and more studies that are showing that a properly executed vegan diet is highly beneficial for cleansing, for detoxing, in addition to lowering the risks for and even ameliorating chronic illness. We all have our own body constitutions and cultural food ways and personal tastes that determine what will work for us.
