Some research suggests foods rich in beta-cryptoxanthin may help lower the risk of bladder, lung and colon cancer.“Beta-cryptoxanthin is an antioxidant, which protects your cells from changes that can lead to cancer,” says Whitson. “And we know that people who eat a variety of fruits and vegetables have a lower risk of cancer overall.” Protect brain healthRed bell peppers contain anthocyanins — natural compounds responsible for their red color. These pigments, found in many dark red or purple fruits and vegetables, may have a protective effect on brain cells. Research shows that anthocyanins could help slow down memory problems and cognitive impairment as we age.Relieve arthritisCartilage is rubbery tissue that covers the ends of your bones and keeps them from rubbing together.
