Role of Zinc Supplement in Development of Immune System-Vitamin

Zinc Antioxidant Vitamins an essential nutrient that has an important role in the growth and development of many cells, tissues, and the immune system. Zinc is considered a cofactor for over 300 metalloenzymes and one of the symptoms of zinc deficiency is an increased frequency of bacterial and viral infections. The effects of zinc and immune function have been well studied. The cellular and molecular effects of zinc on immunity are beyond the scope of this review and the reader is referred to several recent reviews for additional information.

Zinc deficiency may impair nonspecific and specific immune responses. Nonspecific defenses that may be impaired by zinc include NK cytotoxicity, macrophage phagocytosis, neutrophil oxidative burst, and chemotaxis. Other observations include thymic atrophy, decreased DTH, reduction in peripheral T-cell count, decrease in T helper cell and T cytotoxic cell functions, and reduced antibody production. It is apparent that zinc deficiency affects multiple aspects of host immunity and therefore it is not surprising that an increased frequency of infection is observed in deficient individuals. Zinc supplementation of deficient individuals has been shown to reduce the incidence and severity of infection, especially in children.

Although it is clear that malnourished individuals How Vitamins Influence The Skin impaired immunity due in part to zinc deficiency, the question of relevance to normal well-nourished healthy individuals is whether zinc supplementation can enhance immunity. Several studies in the elderly have shown that zinc supplementation is associated with an increased number of T cells, improved delayed dermal hypersensitivity, DTH response, and antibody production to tetanus vaccine. The elderly may suffer from mild zinc deficiency and therefore may benefit from supplementation.

Recently, there has been an interest in the potential role of zinc supplementation in reducing the duration of symptoms associated with the common cold. Some studies have demonstrated that zinc gluconate lozenges administered within 24 hours of the onset of symptoms of the common cold reduced the duration of cold symptoms. However, this is not a consistent finding and a recent meta-analysis that reviewed a number of clinical trials concluded that solid evidence for the effectiveness of zinc lozenges in reducing the duration of common colds is lacking.

Immune Effects and Exercise

Many athletes may be tempted to try zinc supplementation while experiencing symptoms of the common cold in the hope that the duration of cold symptoms will be reduced. Short-term supplementation is probably not harmful, however, high-dose zinc supplementation is associated with immunosuppression. It is not known if zinc supplementation can reduce the incidence of infection in healthy well-nourished individuals. Some evidence supports the concept that zinc supplementation may be considered potentially beneficial during episodes of the common Vitamins in terms of decreased symptoms or duration. However, there is no evidence that zinc can reduce the incidence of the common cold among healthy individuals.

One potential area of consideration for some athletes regarding zinc is the finding that some athletes, particularly endurance athletes, may suffer from mild zinc deficiency This population may be similar to elderly individuals regarding mild zinc deficiency and therefore may benefit from supplementation. However, to our knowledge this possibility has not been tested. Also, keep in mind that the elderly experience an age-associated decline in immune responsiveness and therefore zinc supplementation of younger individuals may not show similar benefits.

One study did compare the postexercise immune response in those individuals who consumed zinc and placebo. The subjects consuming zinc did not experience an exercise-induced increase in neutrophil production of ROS. It is possible that this change may alter exerciseinduced tissue damage. It is not clear at this time how the change in neutrophil function may relate to susceptibility to infection or disease outcome. Again, further research is certainly warranted considering that some athletes may experience mild zinc deficiency and adequate zinc intake is essential for optimal immune response and resistance to infection.

Which Health Drinks Taste Good And Are Better For You Than Sodas, Vitamin Waters, And Energy Drinks?

We know people don't drink sodas because they are a health drink. They drink them because they taste good, they're bubbly Vitamins they lift your spirits for a moment. That is, until the sugar and caffeine crash hits you. With high caffeine energy drinks and sugary vitamin waters, the mood bounce is just as bad, if not worse, as your body tries to adjust to the disastrous combination of sugar and caffeine in dangerously high doses. Why are so many people consuming these very unhealthy drinks?

  • They taste good
  • They provide a temporary mood boost
  • They are relatively inexpensive compared to quality health drinks

What if you could find a health drink that actually tastes good, fills the body with vital nutrients, gives you a mood boost, and costs about the same as one of those sugary vitamin water drinks? Would you be willing to try a health drink that doesn't contain sugar and caffeine, but is loaded with concentrated nutrients from fruits and herbs? What if you knew that these concentrated health drinks were supplying your body with living enzymes, natural antioxidants, complex carbs and phytonutrients from plants? Does that make you at least reconsider your consumption of carbonated caffeine and sugar?

There are many other reasons to consume Why Vitamins And Minerals Are Important To Your Body low carb health drinks instead of sodas, sugary vitamin waters or caffeine boosted energy drinks.

  • Sugar wreaks havoc on the body.
    1. Excess sugar contributes to obesity.
    2. Sugar suppresses the immune system.
    3. Too much sugar can upset the body's mineral balance.
    4. An overload of sugar contributes to arthritis.
    5. Over consumption of sugar speeds the aging process.
    6. All that sugar in soft drinks, energy drinks, and in vitamin waters causes your pancreas to produce excess insulin, which leads to an energy crash.

  • Your overall fitness level increases with natural, low carb health drinks. All those soft drinks and high caffeine energy drinks are very acidic, which contributes to a pH imbalance. The body needs a ratio of 80% alkaline foods and drinks to only 20% acidic foods for proper pH balance. An improper ratio of too many acidic foods and beverages causes the body to break down faster as it pulls calcium from bones in order to maintain the right pH balance. Natural health drinks on the other hand are, more often than not, alkaline by nature.
  • Vitamin waters, soft drinks and energy drinks actually deprive the body of some of the health benefits of drinking water. All the phosphates, sugar, caffeine and artificial ingredients take more water to process than they replace. When the body does not take in enough water and vital nutrients then you experience cellular dehydration, which in turn leads to numerous health challenges.

So, people who are guzzling soft drinks, caffeinated energy drinks and sugary vitamin waters are actually walking around dehydrated. On the other hand, people who are consuming natural health drinks that contain live nutrients from whole foods such as fruits and herbs are enjoying the many health benefits of drinking water plus the numerous benefits of consuming phytonutrients in their water. When you realize that it is a good idea to be more selective in your beverage choices then you have to ask yourself, "Where do I find these health drinks that taste good and offer so many benefits?"

Some of the natural low carb health drinks taste better than any of those artificial vitamin waters and you can drink them in natural flavors of peach, lemon, raspberry, cinnamon and even green tea. With the right health drinks your body not only receives the benefits of drinking water, but also the many health benefits of live, whole food nutrients from real ingredients like peaches, raspberries, lemons and cinnamon.

As you come to understand the differences between live, whole food nutrients and artificially enhanced vitamin waters, sodas or energy drinks boosted with caffeine you make better choices. Your body starts to find its own natural balance and digestion improves, you get fewer mood swings, less stiffness in your joints, more energy and an overall improvement in mood. You feel better about yourself when you replace your overly processed, sugary, caffeine enhanced beverages with health drinks that are truly healthy.
