Oranges, grapefruits, lemons, and limes are famous for vitamin C, which helps increase white blood cell production. Since your body doesn’t make or store vitamin C, you need a daily dose. Start your morning with lemon water or snack on an orange for an easy win.

Broccoli is a powerhouse of vitamins A, C, and E, plus fiber and antioxidants. The trick? Cook it as little as possible—or not at all. Steaming or eating it raw keeps those nutrients intact.

Look for yogurts with “live and active cultures” printed on the label. These probiotics help your gut—which is where most of your immune system lives. Plain yogurt is best; you can sweeten it with fruit and a drizzle of honey.

Vitamin E often takes a backseat to vitamin C, but it’s just as important. Almonds are full of it. A half-cup provides almost all the vitamin E you need in a day. Plus, healthy fats help your body absorb it better.
