Harrelson is also an ethical vegan and raw foodist.
Along with not eating meat or dairy, Harrelson also does not eat sugar or flour.
He did not eat Twinkies for his movie "Zombieland", replacing them with vegan faux-Twinkies made from cornmeal.
He appeared on a postage stamp (as a PhotoStamp) in 2011 as one of PETA's 20 famous vegetarians, and he was named PETA's Sexiest Vegetarian in 2012 (along with Jessica Chastain). 
Originating from what Harriet Bevitt does instead of flyering.
As members of the Animal Rights Community of Cincinnati, Ball and Norris (along with Phil Murray, now co-owner of Pangea Vegan Products) spent the winter of 1990–1991 holding fur protests outside cultural events.
Their focus turned to vegetarianism in 1992, and the Animal Rights Community of Cincinnati funded the printing and distribution of 10,000 pro-vegetarian flyers entitled "Vegetarianism".
In June 1993, twelve activists—including Ball and Morris—held a three-day "Fast for Farm Animals" in front of a Cincinnati slaughterhouse (most animals typically go three days without food before slaughter).
On the last day of the fast, some of the protestors took a large banner reading "Stop Eating Animals" to the University of Cincinnati campus.
Though the fast itself generated some media coverage, many of the people involved felt that holding the banner in the university district was the most effective part of the fast.
Following this event, Ball and Norris formed Animal Liberation Action (ALA) and started a campaign of holding "Stop Eating Animals" banners on street corners.
This would become the foundation of Vegan Outreach's current tactic of disseminating information on college campuses and in other high-traffic areas.
In 1994, ALA developed a booklet called "And Justice For All".
It focused on the reasons to adopt a vegan diet, focusing on the abuse of the animals involved.
The following year, ALA's name was officially changed to Vegan Outreach, and the campaign to hold banners—generally poorly received by the public, who did not understand the reasons behind the request—was set aside in favor of the distribution of printed booklets.
Another revision of the booklet, now called "Vegan Outreach", was printed in 1995.
To save money, the initial 10,000 copy run was stapled, folded, and collated by Ball, Norris, and Anne Green.
That autumn, Norris embarked on a tour of the Midwestern United States, distributing the Vegan Outreach brochure at nineteen universities.
The first "Why Vegan" was printed in 1996 and distributed at 171 colleges during that year.
Norris continued his traveling until funds ran out in 1997.
He decided to become a Registered Dietitian, which entailed three years of school and an internship.
He did this to become educated on the science of nutrition and to figure out what could be done to minimize the number of failed vegetarians in the future. 
Many Worcestershire sauces contain anchovies, which is of concern for people with fish allergies and those who choose not to eat fish.
The Codex Alimentarius recommends that prepared food containing Worcestershire sauce with anchovies include a label warning of fish content although this is not required in most jurisdictions.
The US Department of Agriculture has forced the recall of some products with undeclared Worcestershire sauce (eg).
Several brands sell anchovy-free varieties of Worcestershire sauce, often labelled as vegetarian or vegan.
Alternatively, Henderson's Relish can be used as a vegan substitute for Worcestershire sauce.
Orthodox Jews refrain from eating fish and meat in the same dish, so cannot use traditional Worcestershire sauce to flavour meat.
However, certain brands are certified to contain less than 1/60th of the fish product and can be used with meat. 
DeGeneres is a vegan who calls herself a "big animal lover".
De Rossi is a vegan as well.
Ellen co-ordinates a vegan outreach website titled 'Going Vegan with Ellen'.
She intended to open a vegan tapas bar, Bokado, in Los Angeles, but plans fell through.
The site for "The Ellen DeGeneres Show" contains a section called "Going Vegan With Ellen," in which she promotes "Meatless Mondays" and features vegan recipes.
She has several times invited Humane Society of the United States CEO Wayne Pacelle to speak on her show about the organization's efforts in animal protection legislation.
In April 2013, she donated $25,000 to stop Ag-Gag anti-whistleblower legislation in Tennessee, which would prohibit undercover investigators from recording footage of animal abuse on farms.
DeGeneres served as campaign ambassador to Farm Sanctuary's Adopt-A-Turkey Project in 2010, asking people to start "a new tradition by adopting a turkey instead of eating one" at Thanksgiving.
