7 Zinc-Rich Foods to Supercharge Your Immune System

Oysters

Oysters stand out as one of the richest natural sources of zinc. A 100-gram serving delivers over 20 mg, while a single 50-gram oyster fulfills an adult's daily zinc needs. The zinc here is highly bioavailable, and oysters also provide essential minerals and trace elements for overall health.

Crab

Crab offers a solid 9.8 mg of zinc per 100-gram serving, alongside high-quality protein. It's also packed with vitamin B12—crucial for red blood cell production alongside folic acid—and selenium for added antioxidant benefits.

Toasted Wheat Germ

Toasted wheat germ is a powerhouse, supplying 16 mg of zinc per 100 grams. Stir it into cereals, yogurt, or sprinkle over salads for an easy nutrient boost.

Pumpkin Seeds

Roasted pumpkin seeds load up on zinc at 7.64 mg per 100 grams, plus other vital minerals. Snack on them instead of pistachios, or toss into salads for crunch and nutrition.

Pork Liver

Pork liver delivers 8 mg of zinc per 100 grams, making it a top source of this mineral. It's also rich in iron and B vitamins—perfect for occasional meals to replenish key nutrients.

Rindless Cooked Ham

Rindless cooked ham provides 6.5 mg of zinc per 100 grams. No cooking required: a ham sandwich can cover about 50% of your daily zinc needs effortlessly.

Dried Shiitake Mushrooms

These Japanese-native mushrooms pack 7.66 mg of zinc per 100 grams dried. Rehydrate in lukewarm water for 15 minutes, then boil for 10, and add to soups, stir-fries, or salads.
