The Importance of Our Daily Dose

Because we are talking about a trace mineral which our bodies do not produce, it is important to make sure that our daily intake is high enough. The current RDA recommendation is 15 mg. The substance is generally found in both animal and plant sources, although it is richest in animal food sources.

Some natural sources of this essential mineral are high protein foods such as red meat and poultry, seafood, seeds (especially pumpkin), beans, fortified cereals, wheat germ, oatmeal, nuts, bran flakes, some cheeses and milk. More information is given in table 1, below.

Despite the many benefits of zinc, it is important not to consume too much of it.

Supplementation interferes with the absorption of many other minerals, especially copper, which can lead to copper deficiency. Moreover, long term use of 100mg a day will have negative effects such as the decrease in HDL (good) cholesterol and increase LDL (bad) cholesterol.

It is equally important to not take supplemental zinc unless you have an actual deficiency as this can lead to toxicity. This kind of overdose includes symptoms such as nausea, vomiting and diarrhea. However, a deficiency can also be serious as it can result in poor wound healing, skin problems (such as eczema, acne and psoriasis), weakened immune system, taste impairment, low sperm count for men, poor appetite, fatigue and decrease in growth rate. The key to avoiding both overdose and deficiency is to intake the recommended amount, which can be established by a physician or the RDA

IF you want to age well, make sure you get adequate amounts of this trace element in your daily diet. At the same time make sure you don't overdose by following the RDA recommendations or that of your health authority.
