ED this VD? It’s not you, it’s meat.

Between 18 and 30 million men in the United States have erectile dysfunction. It’s certainly a topic everyone’s familiar with—the image of a little blue pill or two outdoor bathtubs is practically iconic. But most people don’t know that ED isn’t usually caused by stress, alcohol, or performance anxiety—it’s a result of blocked arteries. The cholesterol and saturated fat in animal products can lead to vascular problems, which in turn impede blood flow. Gorge on chicken wings and steak, and the only thing that will grow later is your waistline.

Over a six-year span, the U.S. government spent $172 million on penis pumps—expensive contraptions that try to draw blood flow through narrowed arteries. There’s a much less expensive solution: A low-fat, plant-based diet will reverse artery blockage, letting blood flow to where you need it. In fact, while processed meat products cause low-quality sperm, carrots and other vegetables can actually boost virility.

So to those who take their sweetheart out for a big steak dinner this Valentine’s Day only to discover that they’re having some technical difficulties later on, remember—it’s not you, it’s meat.
