The body does not make iodine, so it is an essential part of your diet. In addition, this mineral is needed for the production of thyroid hormones. As an integral part of thyroid hormones it regulates body temperature, metabolic rate, reproduction, growth, blood cell production, nerve and muscle function and more. By controlling the rate at which the cells use oxygen, these hormones influence the amount of energy released when the body is at total rest. Approximately 70 to 80% of the body’s iodine is found in the thyroid.
Chromium is an essential mineral required in small amounts by the body and plays an important role in the metabolism of carbohydrates and fats. Of significance is the finding that individuals with adequate dietary chromium have improved control over blood glucose and a better blood lipid profile. Chromium helps maintain blood glucose levels by enhancing the activity of the hormone insulin. Like iron, chromium assumes different charges. Cr3+ is the most stable form and is commonly found in foods.
We have all heard the phrase ‘those bones need calcium’ and it is essential advice for all of us! An adequate intake of calcium is one of a number of factors important for acquiring bone mass and attaining peak bone mass. Diets containing insufficient amounts of calcium may lead to lower bone mineral density, which may have implications for bone health, notably risk of osteoporosis later in life. Our bones are gaining and losing minerals continuously in an ongoing process of remodeling. Calcium forms crystals on a matrix of the protein collagen. This process is called mineralization. During mineralization, as the crystals become denser, they give strength and rigidity to the bones. Most people achieve a peak bone mass by their late 20s, and dense bones best protect against age-related bone loss and fractures.
Strictly speaking, choline is not a vitamin, but an essential nutrient that is often grouped under the B-vitamins. While many of us know about the importance of folic acid in pregnancy the value of choline is often overlooked. We now know that choline is especially important during pregnancy as it is involved in fetal brain development.
