20 Foods High in Iron

3. Shellfish

Iron level: 3 ounces of clams, mollusks or mussels contain 3.5 mg or more of iron. This equals 20% of the Daily Value.
Other benefits: Shellfish provide a lot of nutrients including omega 3 fatty acids, minerals like zinc, copper and magnesium and are a good source of protein. Unlike other seafood, these foods also tend to be low in mercury, fat and cholesterol levels.
Things to know: Always be sure to cook shellfish fully since some types can have a higher likelihood of contaminants. Where possible, it is better to opt for domestically caught shellfish paying attention to local water conditions over imported varieties to help lower this risk.
