112 Vitamins and Minerals
Vitamins are organic substances (made by plants or animals), minerals are inorganic elements that come from the earth; soil and water and are absorbed by plants. Animals and humans absorb minerals from the plants they eat. Vitamins and minerals are nutrients that your body needs to grow and develop normally.
Vitamins and minerals have a unique role to play in maintaining your health. For example Vitamin D helps your body absorb the amount of calcium (a mineral) it needs to form strong bones. A deficiency in vitamin D can result in a disease called rickets (softening of the bones caused by the bodies inability to absorb the mineral calcium.) The body cannot produce calcium; therefore, it must be absorbed through our food. Other minerals like chromium, copper, iodine, iron, selenium, and zinc are called trace minerals because you only need very small amounts of them each day. The best way to get enough vitamins is to eat a balanced diet with a variety of foods. You can usually get all your vitamins from the foods you eat.

CDC, Calcium and Bone Health
Bones play many roles in the body. They provide structure, protect organs, anchor muscles, and store calcium. Adequate calcium consumption and weight bearing physical activity build strong bones, optimizes bone mass, and may reduce the risk of osteoporosis later in life.
CDC, Folic Acid
Folic acid is a B vitamin. It is used in our bodies to make new cells. If a woman has enough folic acid in her body before she is pregnant, it can help prevent major birth defects of her baby’s brain and spine.
CDC, Iron and Iron Deficiency
Iron is a mineral needed by our bodies. Iron is a part of all cells and does many things in our bodies. For example, iron (as part of the protein hemoglobin) carries oxygen from our lungs throughout our bodies. Having too little hemoglobin is called anemia. Although anemia has a number of causes, iron deficiency anemia is the most common type of anemia.
Salt
Most of the sodium we consume is in the form of salt, and the vast majority of sodium we consume is in processed and restaurant foods. Too much sodium is bad for your health. It can increase your blood pressure and your risk for a heart attack and stroke.
Sodium and Potassium
Nearly all Americans eat too much salt (sodium). Most of the salt comes from eating processed and restaurant foods (>70%). On average, the more salt a person eats, the higher his or her blood pressure.
