Figure 18.1 (Nutrition’s)
Iodine
Iodine is involved in the synthesis of thyroid hormones. These hormones help to keep
cells and the metabolic rate healthy.
Taking high doses of iodine for long periods of time could change the way your
thyroid gland works. This can lead to a wide range of different symptoms, such as
weight gain.
Similar problems can occur with deficiencies in the amount of iodine in your diet, especially
if you’re pregnant
Copper
Copper helps to produce red and white blood cells, and triggers the release of iron to
form hemoglobin – the substance that carries oxygen around the body, and is thought
to be important for infant growth, brain development, the immune system and strong
bones
Taking high doses of copper could cause: stomach pain, sickness, diarrhea and
damage to liver and kidneys, if taken for a long time.
Iron
Iron is an essential mineral with several important roles in the body. For example, it
helps to make red blood cells which carry oxygen around the body.
A lack of iron can cause iron deficiency anemia and is not uncommon even in the
West.
