Broccoli
You’ve probably noticed there are many vegetables on this list. That’s because they are filled with great vitamins and minerals that can help you get through the cold and flu season. Researchers at the University of California in Los Angeles conducted studies that prove broccoli is a building block for your immune system.
According to the research, there is a chemical in the vegetable called sulforaphane that turns on antioxidant genes and enzymes in specific immune cells. When this happens, the enzymes fight off free radicals in your body and prevent you from getting sick. Even if you need to dip your broccoli in cheese or ranch, it’ll help you stay healthy.
