Sports Nutritionist Nathan Newton talks to GuySpy about Iron and Zinc.

As the nights and days get cold, and England is set to receive an all time low when it comes to winter temperatures, I thought I’d give you some information on Iron and Zinc products to help you fight off those unwanted coughs and colds before they begin to take hold.

Lets look at the basics of these two mineral sources that can easily be found in your daily food intake…..

Considered to be one of the most abundant metals on Earth, Iron is essential to most life forms and to normal human physiology.

In everyday working humans, iron is an essential component involved in the transportation of oxygen around the body, as well as being important for the regulation of cell growth.

There are two main forms of iron that can be found in the diet – heme and nonheme. Heme iron is derived from the protein that is found in red blood cells, and is used to deliver oxygen to the cells. Heme iron is found in animal foods such as red meats, fish, and poultry.

Supplementation of Iron is needed when diet alone cannot provide the body with the necessary levels. It is especially important when an individual is experiencing symptoms of iron deficiency anemia, or low Iron levels. The usual signs of this include tiredness, low concentration levels, constant feeling of being cold, and lightheadedness and dizziness.

Iron deficiency is uncommon among adult men and postmenopausal women, but does regularly occur in vegetarians or low red meat eaters. If this is case, get some more spinach and broccoli down your neck to sort these levels out, and knock that dizziness on the head!

Zinc is found in cells throughout the body. One of its main jobs is to help the immune system fight off invading bacteria and viruses. It is also used by the body to make proteins and DNA. Throughout pregnancy, infancy, and childhood, the body needs zinc to grow and develop properly, it also helps to heal wounds and is important for proper senses of taste and smell.

Zinc is found in a wide variety of food such as Oysters (which are the best source of zinc). It’s also found in red meat, poultry, seafood such as crab and lobsters, and fortified breakfast cereals. Beans, nuts, whole grains, and dairy products, also have some zinc.

Zinc is present in almost all multivitamin/mineral dietary supplements. It is also available alone or combined with calcium, magnesium or other ingredients in dietary supplements. Dietary supplements can have several different forms of zinc including zinc gluconate, zinc sulfate and zinc acetate. As yet, It is not clear whether one form is better than the others, either way neck some zinc to ward off that Christmas cold!
