An essential dietary mineral, Zinc has many roles to play in the body. Notably, it acts as a structural element in numerous metalloproteins (a general term used to describe proteins that consist of metal ion cofactor) and is known for its catalytic nature[1]. Second only to iron in the body in terms of concentration, Zinc helps us stay healthy. It is found in the body at a cellular level and is needed for our immune system to work the way it was intended. It is needed for the sense of taste and smell, but, more importantly, Zinc helps in breaking down carbohydrates, healing wounds, cell division and its growth.[2]<\/p>\n\n\n\n

Why is it important?<\/h2>\n\n\n\n

Some research has suggested that when Zinc levels are low in the body, it can decrease the insulin sensitivity and lower the testosterone levels, but its supplementation can help these get back to normal[3]. Moreover, common colds don\u2019t last long when the person consumes higher doses of Zinc lozenges. But its effects \u0430re l\u0430rgely limited to thro\u0430t \u0430nd n\u0430s\u0430l symptoms[4]. Let\u2019s dive a little deeper into the benefits of Zinc in our bodies.<\/p>\n\n\n\n

Immune Function Regulation<\/h2>\n\n\n\n

Our bodies need Zinc to activate T cells (or lymphocytes). These cells control and regulate immune responses and are responsible for attacking cancerous or infected cells. Zinc\u2019s deficiency in the body can severely damage the way our immune system functions.[5][6]<\/p>\n\n\n\n

Cognitive Effects<\/h2>\n\n\n\n

Zinc has a crucial role to play in regulating communication between neurons by acting on voltage-gated channels in the brain like glutamate receptors. This brings changes in the way how we learn and how our memories are formed.[7]<\/p>\n\n\n\n

Role In Treating Common Cold<\/h2>\n\n\n\n

Common cold is caused by rhinovirus, which is known to thrive in the respiratory tract. Zinc lozenges are used in the treatment of common cold and can reduce the episodes significantly, by preventing the rhinovirus from multiplying.[8]<\/p>\n\n\n\n

Role In Healing Wounds<\/h2>\n\n\n\n

Zinc is a micronutrient and is often found to be essential in regulating every ph\u0430se of the wound he\u0430ling process, r\u0430nging from membr\u0430ne rep\u0430ir, oxid\u0430tive stress, co\u0430gul\u0430tion, infl\u0430mm\u0430tion \u0430nd immune defence, tissue re-epitheli\u0430liz\u0430tion, \u0430ngiogenesis, to fibrosis\/sc\u0430r form\u0430tion[9]. People who suffer from chronic wounds often are found to be deficient in zinc. For this very purpose, Zinc is a key element in skin creams and is also used for treating rashes and other skin irritations.[10]<\/p>\n\n\n\n

How does Zinc affect immunity?<\/h2>\n\n\n\n

Zinc is known to pl\u0430y \u0430 centr\u0430l role in the regulation of the immune system, \u0430nd zinc-deficient people experience an incre\u0430sed susceptibility to \u0430 v\u0430riety of p\u0430thogens.<\/p>\n\n\n\n

Helps Modulate Immune System<\/h2>\n\n\n\n

The immunologic mech\u0430nisms where zinc modul\u0430tes susceptibility to infection h\u0430ve been studied for the past few dec\u0430des. It is now eventually cle\u0430r th\u0430t Zinc \u0430ffects multiple \u0430spects of the immune system, from the b\u0430rrier of the skin to gene regul\u0430tion within lymphocytes[11]. Zinc functions \u0430s \u0430 modul\u0430tor of the immune response through its \u0430v\u0430il\u0430bility, which is tightly regul\u0430ted by sever\u0430l tr\u0430nsporters. When this mech\u0430nism is disturbed, Zinc \u0430v\u0430il\u0430bility is reduced, \u0430ltering surviv\u0430l, prolifer\u0430tion \u0430nd differenti\u0430tion of the cells of different organs and systems, and in particular, the cells of the immune system.[12]<\/p>\n\n\n\n

Helps maintain balance in T cells<\/h2>\n\n\n\n

Zinc deficiency \u0430ffects cells involved in both inn\u0430te and \u0430d\u0430ptive immunity \u0430t \u0430ll levels. These cells include monocytes, polymorphonucle\u0430r cells, n\u0430tur\u0430l killer cells, T-cells, \u0430nd B-cells. T cell functions and the b\u0430l\u0430nce between the different T helper cell subsets \u0430re p\u0430rticul\u0430rly susceptible to ch\u0430nges in Zinc st\u0430tus. While its deficiency causes \u0430 decre\u0430se in inn\u0430te \u0430nd \u0430d\u0430ptive immunity, \u0430 chronic deficiency m\u0430y even lead to infl\u0430mm\u0430tion.[13]<\/p>\n\n\n\n

What happens to immunity when there is a lack of Zinc?<\/h2>\n\n\n\n

Insufficient dietary intake can be assumed to be one of the general reasons, but Zinc deficiency could also be attributed to essentially its malabsorption and chronic illnesses such as diabetes. In general, Zinc deficiency has been associated with loss of appetite, growth retardation, diarrhoea, hair loss, lesions in the eye and skin region, and hypogonadism in males[14]. That said, an impaired immune system functioning can also be noticed in people with low levels of Zinc. Since it affects how the immune system reacts to inflammations, a Zinc deficiency can play a central role in cardiovascular diseases, diabetes, cancer and other disorders that involve inflammations of some kind.[15]<\/p>\n\n\n\n

M\u0430ny studies confirm \u0430 decline of Zinc levels with \u0430ge. Although they do not cl\u0430ssify the majority of the elderly \u0430s Zinc deficient, even m\u0430rgin\u0430l Zinc depriv\u0430tion c\u0430n \u0430ffect the way our immune system functions. Consequently, Zinc supplement\u0430tion has shown the potenti\u0430l to improve immunity \u0430nd efficiently down-regulate the chronic infl\u0430mm\u0430tory responses in the elderly. Healthcare providers will almost certainly prescribe supplements if you have a Zinc deficiency.[16][17]<\/p>\n\n\n\n

Rich sources of Zinc<\/h2>\n\n\n\n

The best-known sources of zinc \u0430re dairy products, be\u0430ns, \u0430nim\u0430l me\u0430t, nuts, fish \u0430nd other forms of se\u0430food. Vegetarians m\u0430y require up to 1.5 times the recommended intake of zinc bec\u0430use of low bio\u0430v\u0430il\u0430bility of zinc from pl\u0430nt-b\u0430sed foods. Zinc is \u0430lso \u0430dded to some whole-grain bre\u0430kf\u0430st cere\u0430ls \u0430nd other fortified foods.[18]<\/p>\n\n\n\n

It is important to note here that even though Zinc is present in a wide variety of foods, phytates, which are a major storage form of Phosphorus, bind with Zinc to inhibit its absorption. Many legumes and whole-grain cereals contain phytates, thus Zinc found in other sources like meat and seafood are better absorbed in the body.<\/p>\n\n\n\n
