as you can read in this blog post by Juliet Eilperin at the Washington Post.
She notes that the story first surface in a passing mention in this Forbes piece on Hampton Creek Foods. The relevant paragraph in the Forbes piece, without the hot links, is as follows (with the specific words in bold):
While Tetrick, Hampton Creek’s CEO, hasn’t been able to persuade everyone, it’s the type of people he has convinced that has the San Francisco food startup turning heads. Bill Gates is a backer, handpicking the company as one that could change future food production. Tetrick has raised $6 million to date from the likes of Peter Thiel’s Founders Fund, Vinod Khosla’s Khosla Ventures and environment-friendly billionaire Tom Steyer. Newly turned vegan Al Gore is also circling.Again, without the hot links, two relevant paragraphs from Eilperin, right after she has quoted the words I bolded from the Forbes piece:
An individual familiar with Gore's decision, who asked not to be identified because it involved a personal matter, confirmed that Gore opted a couple of months ago to become vegan. Gore's office did not immediately respond to a request for comment.One could posit that Gore, whose weight had ballooned, took the approach at least in part for health reasons.
It is unclear why Gore, one of the nation's most visible climate activists, has given up dairy, poultry and meat products. People usually become vegan for environmental, health or ethical reasons, or a combination of these three factors.
What is now means is that the previous Democratic executive branch leaders were not only both Southern Baptists from adjacent states, but have moved to a dietary pattern that is very different than that of most Americans. We can wonder what impact that might have.
