Nina and Randa Nelson are identical twins. They were raised vegan, so they didn’t eat animal foods. At the age of 20, in the spring of 2014, they developed severe acne. They consulted with three dermatologists, took several courses of antibiotics, used special cleansers, tried blue light therapy (I never heard of that), all without success. After reading this article that linked dietary fat with acne, they eliminated foods they had recently added in larger quantities … especially peanut butter, soymilk and other soy foods, cooking oils, avocado, almonds and other nuts. (“We eliminated many of the vegan foods we had been eating like soymilk, guacamole, avocados, nuts, hummus, Clif bars, olives, and peanut butter.”)

Here’s their story:
Nina & Randa Nelson: Cure Embarrassing Acne & Oily Skin

These before and afters photos are about 6 weeks apart:

Their present diet consists of “oatmeal, … brown rice with veggies, potatoes, sweet potatoes & steamed veggies, condiments, lots of beans, applesauce, yonanas with oats, whole wheat or rice pasta with spices to jazz it up. We also eat extra fruit, dried fruit, and smoothies with oats in order to keep our weight on.”

Of course, this is just a testimonial. It’s hard to say if the foods they stopped eating really did cause their acne. It’s hard to say if it was the fat in them or the protein. Some people have an allergic reaction to proteins in peanuts, tree nuts, and soy beans. Still, a low-fat, starch-based, plant food diet is an easy, inexpensive, no-risk therapy to try if you suffer from acne.
