If your body lacks iron you can develop iron-deficiency anaemia with symptoms including tiredness, pallor, irritability and reduced resistance to infection. Women, in particular need to ensure enough iron in their diet as they lose iron with period evey month
Iodine produces thyroid hormones, which regulate the metabolic rate and vital bodily functions such as body temperature, growth and development in children, blood cell manufacture and nerve and muscle function.

What Are Vitamins and Minerals?
Vitamins and minerals make people's bodies work properly. Although you get vitamins and minerals from the foods you eat every day, some foods have more vitamins and minerals than others.
Vitamins fall into two categories: fat soluble and water soluble. The fat-soluble vitamins — A, D, E, and K — dissolve in fat and can be stored in your body. The water-soluble vitamins — C and the B-complex vitamins (such as vitamins B6, B12, niacin, riboflavin, and folate) — need to dissolve in water before your body can absorb them. Because of this, your body can't store these vitamins. Any vitamin C or B that your body doesn't use as it passes through your system is lost (mostly when you pee). So you need a fresh supply of these vitamins every day.
Whereas vitamins are organic substances (made by plants or animals), minerals are inorganic elements that come from the soil and water and are absorbed by plants or eaten by animals. Your body needs larger amounts of some minerals, such as calcium, to grow and stay healthy. 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.
