New York City's 11 public hospitals have switched to plant based meals without meat or dairy. Just don't call them vegan, as it may turn off people, says an official of the New York City Health and Hospital Corporation. An Oxford University study shows that plant based diets account for 75% less greenhouse gas emissions than diets with 3.5 ounces of meat a day. Satisfaction is 90%. The hospital system reduced its carbon emissions food related by 36%. It expects to turn out 800,000 plant based dishes this year at its hospitals.
