Iron and vitamin D are essential nutrients to ensure that your blood, cells, bones and muscles remain in good health. Iron is crucial for the formation of red blood cells, which carry oxygen throughout the body. It is also part of proteins that are also involved in the transport of oxygen, namely hemoglobin and myoglobin. Hemoglobin is a protein in red blood cells that carry oxygen to the tissues, and myoglobin is the protein that carries oxygen to the muscles. Vitamin D aids in calcium absorption and regulating blood calcium levels. It is also crucial for strong bones and teeth. A healthy diet includes foods rich in iron and vitamin D.

Foods With Iron
Dietary iron comes in two forms: heme and nonheme. Heme iron is present in animal goods, such as fish, poultry and red meat, and is better absorbed in the body. Nonheme iron is present in plant foods, such as beans and lentils, and is also the form added to iron-fortified or enriched foods. Excellent sources of iron include liver, lean red meat, egg yolks, salmon, tuna, and oysters. Sources of nonheme iron include legumes, such as dried beans and peas, raisins and prunes, kidney beans, soybeans, spinach, collard, kale and dandelion greens, broccoli and whole grains.
