Missing This Trace Element In Your Diet Detrimental To Your Health

Even a small deficiency can cause a big impact on most living organisms after only ten days.

Zinc is an essential trace element which has a huge impact on human metabolic functions.

It is crucial for the immune system to work properly and is involved in the breakdown of carbohydrates, insulin function, cell growth and wound healing.

This trace mineral has to be consumed in the diet as it only exist in small amounts in both humans and animals.

Zinc enriched foods include beef, lamb, cooked oysters, egg yolks, pork, dark chocolate, cheese, nuts, seeds, spinach, legumes and whole grains.

The research team at the Technical University of Munich observed that slight zinc depletion can damage the efficiency of digestion and the pancreas.

In this study, pigs were divided into groups and fed a diet with different amounts of zinc over 8 days.

After a week  the pigs developed early-stage zinc deficiency without any visible symptoms.


Their bodies tried to absorb zinc more efficiently, but pancreatic zinc excretion was reduced, and so the test animals’ appetite reduced.

Dr  Brugger explained:

“Various hypotheses were derived, for example, that zinc deficiency had a direct impact on the vagus nerve.

The real reason, however, may be much simpler: the accumulation of undigested food inside the gastrointestinal tract due to zinc deficiency results in feeling less hungry.”

The pancreas acts as the control centre for digestion of food.

To  keep a consistent zinc level, the pancreas pumps zinc into the gastrointestinal tract under normal circumstances.

Since the body only needs small amounts of zinc, it tries to hold on to the stored level.

Therefore pancreatic zinc excretion will reduce to a minimum when the body is low in zinc.

Dr  Brugger said:

“We proved that there is a direct correlation between the amount of digestive enzymes inside the pancreas and zinc levels in the organism as a whole.

Even short intervals of zinc deficiency in the diet should therefore be avoided.

Given the similarities between a pig’s organism and the human organism, we may draw the following conclusion when applying our results to the human body: an egg or two more once in a while can do no harm.”

Older people, vegans and vegetarians should check their zinc intake regularly.
