In a new interview, Samuel L. Jackson reveals that his decision to go vegan last August came after doing some personal first-hand research. 

"Reading Dr. Esselstyn’s book," he told Nell Alk of Ecorazzi of the inspiration behind his shift. "Going to his house and talking to him and his wife Anne and a desire to live forever."

Readers will likely be familiar with Dr. Caldwell Esselstyn as one of the stars of the documentary "Forks Over Knives," which influenced many in Hollywood to give plant-based diets a shot. Esselstyn, a cardiology surgeon, has been a leading figure in promoting plant-based diets as a means to address chronic diseases instead of medication. His 2007 book "Prevent and Reverse Heart Disease" was cited by former President Bill Clinton as influential in his decision to embrace a plant-based diet

"They say risk factors are diabetes, high blood pressure, smoking and maybe too much saturated fat. But when you really come down to it, food trumps them all," Dr. Esselstyn told the Chicago Tribune last year

Jackson's consultations with Dr. Esselstyn have certainly paid off, with the 65-year-old drawing attention during his media tour for "Captain America 2: The Winter Soldier" with his svelte new frame; a loss of over 40 pounds. 

"I feel great. I have a lot more energy than I used to have," he added to Ecorazzi. "I sleep better. I like the way I look in my clothes better. I don’t cramp as much. I exercise better. I think my circulation has gotten better.”
