Two shrimp nutritional standouts are selenium and astaxanthin. Three ounces of shrimp provides 48% of recommended selenium. Selenium is an antioxidant that helps neutralize damaging free radicals. This, in turn, reduces risk for cancer and heart disease. Selenium is an essential nutrient for production of glutathione peroxidase, which is another powerful inflammation-reducing antioxidant. Astaxanthin is a carotenoid pigment that gives fish and shrimp a pink color. Also an antioxidant, it contributes to heart health and reduced risk of cancer. (picture unrelated I just think it's cool)
