Note de contenu : Zinc is a mineral which has many important functions in the body. Its role in human health has been appreciated only relatively recently and there is still research to be done to reveral the ways in which it functions. Zinc is important at the cellular level, in every organ and body system. It is sais to play three major biological roles; catalytic, structural and regulatory.
Zinc is a component of over 300 metalloenzymes and stabilises the structure of numerous proteins, notably a family of proteins that are involved in binding ti DNA and regulating gene transcription. As a component of proteins, zinc is essential to cell growth, differentiation, development, division, DNA synthesis and RNA transcription, among other things. It is involved in processes such as protein digestion and synthesis, carbohydrate metabolism, collagen production, bone metabolism, oxygen transport and protection against free radical damage (Garrow, James & Ralph, 2000; National Health [MoH], 2014). As regards lactation, zinc is essential to breast development and is secreted into breastmilk.
This paper outlineshow a healthy diet meets our zinc needs and provides examples of the ways in which zinc is involved in lactation. Since it is integral to so many physiological processes, zinc nutrition is an underlying element in multiple aspects of healthy functioning, notably in foetal growth, immune system function, blood clotting, bone mineralisation and cognitive function (Chasapis, Loutsidou, Spiliopoulou & Stefanidou, 2012). Zinc nutrition is throught to be involved in risks for cardiovascular diseases, diabetes, oxidative stress, cancer, ageing and depression (Chsapis et al., 2012).
Zinc is indeed an essential micronutrient.[Introduction de l'auteur]
