Zinc deficiency mistakes you might not realize you're making
While severe deficiency in zinc isn't very common, particularly in developed nations, many people in the United States actually have marginal deficiencies, especially elderly persons. And there is a number of reasons and causes behind why deficiency in this essential mineral could be quite prevalent now.
One big reason for zinc deficiency is that food consumed today has less zinc than in years past -- soil demineralization due to modern farming methods and food processing are two culprits for today's reduced dietary zinc intake.
As zinc is water-soluble, canning foods or cooking them in water can cause the removal of zinc.
Other food-related issues are high calcium:zinc and iron:zinc ratios in the diet, as excess calcium and iron can affect the absorption of zinc.
Dietary habits and lifestyle choices which can also contribute to zinc deficiency include:
• consumption of fiber or phytates (compounds found in grains and legumes), as they bind to zinc and reduce the amount of the mineral which is absorbed by the body
• drinking of hard water
• strict vegetarianism, as such a diet would usually contain high amounts of fiber, phytates and oxalates, which affect zinc absorption; generally speaking, zinc in animal-based foods, which is bound with proteins, is more bio-available to the body than the zinc found in plant-based foods
• high copper intake, as it lowers zinc levels in the body; copper can be found in supplements, birth control pills and water which runs through copper pipes
• alcohol consumption -- alcohol flushes zinc out from the liver
• heavy perspiration, for example through regular sports, as zinc is lost in sweat
• stress, which raises the body's zinc usage
Other situations which could result in zinc depletion or an increased need in zinc include dialysis, diuretic therapy, hospitalization and surgery.
Specific groups of people need more zinc
Broadly speaking, elderly persons, pregnant and lactating women, children undergoing growth spurts (e.g., infancy and puberty) and women using oral contraceptives have higher zinc requirements.
Indeed, it has been found that infants, adolescents, women and the elderly are more likely to suffer from zinc deficiency, due to their intakes not matching their increased needs.
Health conditions linked to zinc deficiency
Further, there are numerous health conditions which are implicated in zinc deficiency, contributing either to lowered zinc absorption by the body or elevated zinc needs. Some of these ailments include:
• blood loss (chronic)
• burns, injuries and wounds
• celiac disease
• chronic diseases such as cancer
• diabetes
• diarrhea
• infections or inflammation, whether acute or chronic
• inflammatory bowel disease
• intestinal resection
• kidney disease
• liver cirrhosis
• liver disease
• malabsorption arising from pancreatic insufficiency or post-gastrointestinal surgery
• parasites
• psoriasis
• short bowel syndrome
