\r\n Zinc is a trace element necessary for protein, carbohydrate and fat \r\n metabolism. Like minerals<\/strong>, trace elements are essential for the \r\n proper functioning of the body. Zinc plays many roles such as \r\n intervention in several enzymatic reactions. What are the other roles of \r\n zinc? What are the recommended nutrients for this trace element? In case \r\n of deficiency or overdose, what are the impacts? The answers will be \r\n given in this article.\r\n <\/p>\r\n

\r\n What is zinc?\r\n <\/h2>\r\n

\r\n Zinc is one of the antioxidant trace elements that are found \r\n particularly in muscles and bones. It is symbolised as ZN in the \r\n periodic table of elements.\r\n <\/p>\r\n

\r\n What does zinc do in the body?\r\n <\/h2>\r\n

\r\n Zinc plays many roles in the body. It is essential for the activity of \r\n more than 200 enzymes.\r\n <\/p>\r\n

\r\n Zinc is involved in the metabolism of proteins and fats.\r\n <\/p>\r\n

\r\n It produces prostaglandins, components that can act as an \r\n anti-inflammatory from polyunsaturated fatty acids including omega 3 and \r\n 6.\r\n <\/p>\r\n

\r\n It plays an antioxidant role in the structuring of superoxide dismutase.\r\n <\/p>\r\n

\r\n It helps stabilise several hormones such as insulin, gustin and thymulin.\r\n <\/p>\r\n

\r\n Zinc is also essential for the immune system. It is essential for the \r\n sense of taste and smell.\r\n <\/p>\r\n

\r\n It helps to keep skin and hair in good condition.\r\n <\/p>\r\n

\r\n It also promotes healthy growth.\r\n <\/p>\r\n

\r\n What are the recommended nutritional references?\r\n <\/h2>\r\n

\r\n Here is a reference table of zinc intake for each age group:\r\n <\/p>\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n

\r\n What foods provide zinc?\r\n <\/h2>\r\n

\r\n Seafood, organ meats, cheeses and meats are food sources that provide \r\n the most zinc. Nuts, eggs, unrefined cereal foods and vegetables are \r\n also rich in zinc.\r\n <\/p>\r\n

\r\n For example: 30g of comt\u00e9 cheese + 100g of minced steak + 5 thin slices \r\n of bread equals 100g + 1 teaspoon of pine nuts equals 10g = 100% of the \r\n recommended zinc intake for a woman.\r\n <\/p>\r\n

\r\n The body absorbs zinc from animal sources better.\r\n <\/p>\r\n

\r\n Here is a reference list for foods of animal origin:\r\n <\/p>\r\n

\r\n Zinc content in mg per 100 g of food\r\n <\/p>\r\n

    \r\n
  • \r\n Rye bread 1\r\n <\/li>\r\n
  • \r\n Maroilles 9\r\n <\/li>\r\n

  • \r\n Unsweetened cocoa powder 6,9\r\n <\/li>\r\n <\/ul>\r\n

    \r\n What is the impact of under or overdosing?\r\n <\/h2>\r\n

    \r\n Zinc deficiency: causes and risks\r\n <\/h3>\r\n

    \r\n Zinc deficiency can be caused by several sources. Especially in the case \r\n of insufficient intake due to a vegan diet for example, or following \r\n obesity surgery which causes food disgust. It can also be caused by poor \r\n assimilation as in the case of intestinal disease.\r\n <\/p>\r\n

    \r\n In case of zinc deficiency, it causes immunity disorders. Hair loss \r\n occurs. In the case of skin lesions, healing is difficult. It also \r\n causes problems with vision, taste and smell.\r\n <\/p>\r\n

    \r\n For men, zinc deficiency leads to abnormal and low sperm production or \r\n oligospermia, which can affect fertility.\r\n <\/p>\r\n

    \r\n For alcoholics, zinc deficiency affects the activity of enzymes in the \r\n liver that break down alcohol. This causes an increase in the toxicity \r\n of alcohol.\r\n <\/p>\r\n

    \r\n In pregnant women, this deficiency leads to foetal malformation or \r\n hypotrophy, i. e. the foetus is too small.\r\n <\/p>\r\n

    \r\n For young children, zinc deficiency has a great impact on growth. It \r\n delays the growth of the child.\r\n <\/p>\r\n

    \r\n In case of zinc overdose: causes and risks\r\n <\/h3>\r\n

    \r\n In case of zinc overdose, the immune defences will be affected and it \r\n will decrease the blood level of good cholesterol (HDL-Cholesterol). It \r\n also increases oxidative stress, which is supposed to be reduced with a \r\n nutritional dose. In particular, by decreasing the action of superoxide \r\n dismutase.\r\n <\/p>\r\n

    \r\n According to an AREDS 1 study, an overdose due to a supplementation of \r\n 80mg of zinc per day during more than 6 years caused genito-urinary \r\n disorders which required hospitalizations.\r\n <\/p>\r\n

    \r\n Note that the safety limit has been limited to 15mg of zinc per day. All \r\n intakes are included, including food and dietary supplements. Care \r\n should be taken with dietary supplements as they are very close to the \r\n Recommended Dietary Allowance.\r\n <\/p>\r\n

    \r\n What are the interferences?\r\n <\/h3>\r\n

    \r\n Zinc uptake is increased by proteins of animal origin.\r\n <\/p>\r\n

    \r\n On the other hand, the assimilation of zinc is decreased by the presence \r\n of phytates in whole grain foods or pulses. They block it in the \r\n digestive tract. However, they are inactivated in sourdough breads.\r\n <\/p>\r\n

    \r\n Dietary supplements of iron, copper and\/or calcium also reduce the \r\n uptake of zinc. It is therefore preferable to take them between meals \r\n with an interval of at least 2 hours.\r\n <\/p>\r\n

    \r\n For a better assimilation of zinc supplements, it is ideal to take them \r\n on an empty stomach. It should be noted, however, that they can reduce \r\n the assimilation of copper. It is therefore recommended to choose a \r\n supplement that contains a mixture of zinc and copper at the same time. \r\n Of course, in nutritional doses and taken at intervals of 2 meals.\r\n <\/p>\r\n

    \r\n It is also advisable to take cyclins, fluoroquinones, which are families \r\n of antibiotics, and strontium at least 2 hours apart from zinc \r\n supplements, since zinc reduces the assimilation of the latter.\r\n <\/p>\r\n

    \r\n To conclude\r\n <\/h2>\r\n

    \r\n In summary, zinc is essential for the body to function properly. When \r\n taking zinc, apart from food sources, the ideal doses for each age group \r\n and situation must be respected.\r\n <\/p>\r\n

    \r\n Care must also be taken when taking supplements to avoid interactions. \r\n Eating foods that are sources of zinc will also help to avoid \r\n deficiency. As far as overdosing is concerned, to avoid the risks caused \r\n by overdosing, you just have to respect the nutritional reference.\r\n <\/p>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
