Oran Hesterman is a brilliant philanthropist. He had so many progressive ideas about shifting the way that money is given out. He wanted to focus on the creation of healthy, community-based food systems in historically excluded communities and now an advocate, an ally, and obviously lots of capital won't be able to go into these communities now.

What makes the farmers market such a special place is that you are actually creating community around food.

The thing that I think about most often is the loss of biodiversity. We talk about these food issues so often with concern to historically excluded communities, but I'm concerned with everyone having access to healthy foods. Consumers across the board are being robbed of biodiversity.

I think more and more foundations are putting resources into food activism. But I think that given the state of the economy, foundations won't be giving as much in general. For me it's about working with these existing institutions in communities that people already go to, that people trust, that they know, and determining how best they can play a role in the creation of local food systems and address the ills that are right around them in the community.

I'm in San Francisco because of the energy, the ideas, and the fact that this is a great place for me to land. When I'm traveling and working nationally, I love coming back here.

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.

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.
