Iron is a mineral that serves several important functions, its main one being to carry oxygen throughout your body as a part of red blood cells (1Trusted Source).
It’s an essential nutrient, meaning you must get it from food. The Daily Value (DV) is 18 mg.
Interestingly, the amount of iron your body absorbs is partly based on how much you have stored.
A deficiency can occur if your intake is too low to replace the amount you lose every day (2Trusted Source).
Iron deficiency can cause anemia and lead to symptoms like fatigue. Menstruating women who don’t consume iron-rich foods are at a particularly high risk of deficiency.
Luckily, there are plenty of good food choices to help you meet your daily
Here are 12 healthy foods that are high in iron.
Shellfish is tasty and nutritious. All shellfish is high in iron, but clams, oysters, and mussels are particularly good sources.
For instance, a 3.5-ounce (100-gram) serving of clams may contain up to 3 mg of iron, which is 17% of the DV (3Trusted Source).
However, the iron content of clams is highly variable, and some types may contain much lower amounts (4).
The iron in shellfish is heme iron, which your body absorbs more easily than the non-heme iron found in plants.
A 3.5-ounce serving of clams also provides 26 grams of protein, 24% of the DV for vitamin C, and a whopping 4,125% of the DV for vitamin B12.
In fact, all shellfish is high in nutrients and has been shown to increase the level of heart-healthy HDL cholesterol in your blood (5Trusted Source).
