According to Dr Abizer Manked (Consulting Physician and Diabetologist) from Saifee Hospital, micronutrients are known to be a major nutrient group that the human body requires. They include Vitamins –Vitamin A, vitamin B, vitamin C, vitamin D, vitamin E, and Minerals – Iron, calcium, magnesium, zinc and selenium.
While Vitamins are essential for the immune system, blood clotting and the consistent production of energy in the body, minerals play a vital role in maintaining bone health, growth, balancing fluids and a number of other processes. Micronutrients are also referred to as ‘essential nutrients’ as they form an important part of daily food, for the body to obtain the required vitamins and minerals.
Types and Functions –
As micronutrients, vitamins and minerals are broadly classified into four categories that include: water-soluble vitamins, fat-soluble vitamins, macro minerals and trace minerals. All of these are absorbed by the body in similar ways and tend to interact amidst processes within.
Water-soluble vitamins are known to dissolve easily and do not remain stored in the body if consumed in excess, as they get flushed out through urination. They include – Vitamin C (ascorbic acid) and the vitamin B complex: thiamin (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), Vitamin B6, biotin (B7), folic acid (B9), Vitamin B12, and Vitamin A (in its Beta-Carotene form). While each of them has an individual part to play, their functions are all interrelated.
Conversely, fat-soluble vitamins do not dissolve in water and are known to get absorbed when consumed along with a source of fat, after which they are stored in one’s liver and fatty tissues, to contribute to functions in the future.
With respect to essential minerals, Macro minerals are required in huge amounts in order to perform their respective roles in the body. They include – calcium, phosphorus, magnesium, sodium, potassium, chloride and sulphur. Trace minerals, on the other hand, include – iron, manganese, copper, iodine, zinc, cobalt, fluoride and selenium, and are required in small amounts to efficiently perform functions in the body.
The prime benefit of a balanced amount of micronutrients in the body is to effectively support functions within. Vitamins and Minerals are essential for combating diseases, thereby improving the immune system, as they form an integral part of almost every internal process while maintaining one’s metabolism.
Some micronutrients also serve as antioxidants and aid in preventing oxidative cell damage, as well as lowering the risk of cancer and Alzheimer’s, among others. A number of them also fights to age.
As they are required in smaller amounts, micronutrients are commonly known as “magic wands” as behind the scenes, they synthesize DNA and significantly contribute to the production of enzymes, and other important hormones in the body, which are crucial for the effective growth and development of the human body.
The deficiency of micronutrients is a global issue, as consuming lesser than the required amounts can create a host of harmful side effects in the body.
While adults are known to consume adequate vitamins and minerals daily through food and fluids, but on the other hand; women, children and senior citizens are prone to a deficiency of these essential micronutrients, which include – Vitamin D, Vitamin B12, Vitamin A, Iron and Calcium. These deficiencies are not only found in developing nations but also in developed ones.
B12 deficiency is commonly observed in people who adhere to a purely vegan diet, are taking certain medications, or suffer from diseases like atrophic gastritis, inflammatory bowel disease and other endocrinal disorders. Early symptoms of b12 deficiency, however, are usually very mild, such as irritation, lack of concentration, tingling sensation in one’s soles, etc.
As another vital micronutrient, the consumption of iodine through salt is imperative for growing children, and a deficiency of the same can cause severe brain damage. This tends to keep them away from attaining their intellectual and developmental potential.
Deficiency of iron is observed especially in women who need it the most. This leads to a higher risk of maternal mortality, and making a person prone to anaemia, resulting in weariness. Weak immunity is another long-term negative effect of iron deficiency. While the deficiencies of these micronutrients are not always visible or detected promptly, they can have significant adverse effects on the functioning of the body and mind, in the long haul.
Choosing foods to get enough Micronutrients –
While supplements are a safe source of availing essential micronutrients and preventing any kind of deficiency, the most effective way is through the consumption of nutritious food.
Following are some of the foods that can be included in one’s daily diet to absorb required micronutrients: Vitamin A –cheese, milk, egg yolk, orange and yellow fruits and vegetables; Vitamin B –whole grains, nuts, seeds, legumes and leafy vegetables; Vitamin C and D–broccoli, cabbage, parsley, strawberry and citrus fruits; Vitamin E –olive oil, wholegrain cereals and avocado; Iron –leafy vegetables, legumes and lean meat; Calcium – almonds and dairy products; Magnesium – seeds, whole grains and nuts; Zinc – chicken, fish, pumpkin and sunflower seeds; Selenium – sunflower seeds, oats and wheat germ.
