Venus Williams has recently been diagnosed with Sjogren's syndrome, an autoimmune disease. To show support for her sister, Serena Williams has switched up her diet.
"I've always been a better eater than her, even though I'm a lot, lot thicker," Serena said, adding that the two live together in Florida. "I don't want her to come home and see a piece of chicken and be like, 'Oh, I want it', and she can't have it. It would be like a stumbling block for her."
Part of the diet change includes more raw foods and cutting down on chicken and fish.
