Zinc - the final and one would argue most crucial piece of this A-Z survival guide!
Zinc is known as a type II nutrient due to its ESSENTIAL role in human growth and health alongside essential amino acids, magnesium, phosphorous, protein and sulfur.
Its role in the body is to aid growth, hormone production - reproductive and blood sugar regulating, gut repair, hair, skin and nail growth and maintenance and most importantly, right now, immune function.
Mild deficiencies can show as constant cold and flus, lack of taste/smell or weak nails.
When chronic or severe this can turn into infertility (male and female), dermatitis, alopecia, diarrhoea, erectile dysfunction, night blindness, and impaired wound healing. Not to mention what it is doing to any unborn babies.
Zinc is lost daily to stool, urine, skin and semen and constantly needs replacing through diet or supplementation.
Animal protein and shellfish are the best sources for quantity and bioavailability. Also found in nuts, seeds, whole grains and legumes though the high phytate content of these foods block its absorption making it less available for utilisation. Sprouting or fermenting these foods increases zincs chances of having an effect.
Other things getting in zincs way are coffee, calcium and soy.
For this reasons, those at highest risk for deficiency are small children, vegetarians, adolescent females and the elderly.
I can’t stress the importance of zinc enough in all walks and stages of life, for oyster lovers this is an invitation to indulge... for everyone else find a source that works for you because we are as useless as an empty oyster shell without this one!
