The first step in aiding mineral absorption is to consume a diverse range of nutrient-rich foods. Different minerals often interact with each other, and a well-balanced diet increases the chances of absorbing a broader spectrum of essential minerals. Include a colourful array of fruits, vegetables, whole grains, nuts, and seeds in your meals. The way you prepare your food can significantly impact mineral availability.

Mineral absorption in body -

Strict vegans, who shun all animal-based products, may sometimes struggle to get enough B But for the most part, it isn't for lack of intake that B 12 deficiency develops.

It typically occurs because of shortages of substances inside the digestive system. Some people lack intrinsic factor, a protein made by stomach cells that's needed for B 12 to be absorbed further down the pike, in the ileum, the end portion of the small intestine.

And many older people secrete fewer of the gastric juices that break down B 12 -containing compounds because they have atrophic gastritis, an inflammatory condition that affects the lining of the stomach. Folate deficiencies occur for a number of reasons, including poor diet, too much alcohol alcohol interferes with the absorption of folate , and B 12 deficiency, because folate needs B 12 to be metabolized.

Deficiency in either or both vitamins may cause macrocytic anemia, a form of anemia that results in enlarged red blood cells. Remedying a B 12 deficiency can be pretty straightforward. You can get injections every few months or take a pill daily.

Even if you're low on intrinsic factor or have atrophic gastritis, the dose in the pills is often large enough 1 mg that an adequate amount of the vitamin gets absorbed.

Folate deficiencies can be corrected with multivitamins or folic acid pills. In fact, folate from fortified food or a pill is absorbed and metabolized almost twice as well as folate found naturally in food. Similar to the B 12 —intrinsic factor dynamic, if you ingest large amounts of folate, some manages to get absorbed even if levels of its B 12 partner are low.

There is an interesting twist to the B 12 -folate story. Doctors often stumble upon the existence of a B 12 deficiency by finding macrocytic anemia after ordering a routine blood test.

Tests for folate and B 12 aren't usually ordered. When someone with a B 12 deficiency takes folic acid supplements, those supplements can make the macrocytic anemia go away — or prevent it from happening. But that eliminates the most common clue to B 12 deficiency, and the deficiency itself may continue.

B 12 deficiencies cause neurological problems, which range from mild tingling sensations to memory loss, in addition to anemia. So people live with neurological problems that might have been easily and inexpensively treated with some extra B We associate copper with pennies, wire, and pans, but it's also an essential nutrient.

Zinc is a little more familiar as an edible substance, partly because people take zinc lozenges in the belief that extra zinc shortens the duration of a cold the evidence is mixed on whether it actually does. Adults are supposed to get micrograms of copper daily.

The daily zinc goals are 11 mg for men and 8 mg for women. Neither mineral is rare in the American food supply, so copper and zinc deficiencies don't loom large in the nutritional worriment — with a couple of interesting exceptions. Copper and zinc compete for absorption sites in the small intestine.

If there's a lot of zinc around, copper tends to lose out and a copper deficiency may develop. Some people in the early stages of macular degeneration, an eye condition that can lead to blindness, are prescribed a special vitamin-mineral combination, called AREDS, which has been shown to slow down progression of the disease.

The AREDS pills include 80 mg of zinc, enough to cause a copper deficiency, so 2 mg of copper were added to the pills. Another possible source of zinc overload is, of all things, denture cream.

A report published in in Neurology described four cases of denture wearers with neurologic abnormalities. Their problems were ascribed to a copper deficiency from zinc exposure that came from using very large amounts of denture creams. A neurologist at Harvard-affiliated Beth Israel Deaconess Medical Center diagnosed a similar case of denture cream—induced neurologic abnormality in Niacin is one of the B vitamins, although it rarely goes by its B vitamin moniker, B 3.

These days, it's probably best known for its cholesterol effects. Large doses mg to 1, mg per day lower "bad" LDL cholesterol and increase "good" HDL cholesterol. Those pharmacological doses far exceed the amounts needed for nutritional purposes.

The daily niacin requirement is 16 mg for men and 14 mg for women. Amino acids are the building blocks of protein, and tryptophan is one of nine that we need to ingest because the body doesn't synthesize them on its own.

Tryptophan is important for several reasons, but chief among them is its role as a supplier of niacin, courtesy of some rather complicated metabolism.

So one way to avoid niacin shortfalls is to eat foods that contain a lot of tryptophan. Chicken and turkey are high on that list. Pellagra, now held up as the classic disease of niacin deficiency, was once thought to be caused by a tryptophan deficiency. The disease, which causes a bad rash, diarrhea, and dementia, was common in the American South in the early 20th century.

How researchers traced it back to a niacin deficiency and a corn-based diet is one of the great tales of nutritional epidemiology.

Interactions with compounds in foods Antioxidants like phytates or polyphenols can bind with certain micronutrients in the gastrointestinal tract and prevent absorption into the body.

What can we do? To increase the bioavailability of nutrients in foods with rigid tissue structures, chop or mince the food before consumption. For example, in order to get the most folate a water-soluble B vitamin from spinach, mince or chop the leaves. If you are a vegan or vegetarian and not consuming foods with heme iron fish, meat, poultry , increase your consumption of foods that are good sources of non-heme iron like nuts, beans, vegetables, and fortified grain products.

Antioxidants like phytates and polyphenols are reduced in the processing or treatment of foods. Examples include pounding grains to remove the bran, soaking grains in water and discarding the water phytate is water-soluble , or cooking foods like beans to reduce polyphenols. While antioxidants are important dietary components, consider balancing consumption of both raw and cooked foods to ensure maximum micronutrient absorption.

Consume foods that work together to increase absorption of certain micronutrients. Eating citrus foods or foods high in vitamin C with foods high in iron increases the absorption of both heme and non-heme iron.

This also prevents minerals from binding with phytate or polyphenols in the gastrointestinal tract. Did you find this article useful?

This minimizes absorption of toxic trivalent metals e. Intracellular metal-binding molecules such as mobilferrin may be present at the intracellular side of the apical membrane, anchored to a transmembrane protein such as an integrin complex. This mobilferrin would receive the metal ion from divalent cation transporter 1 and, with part of the integrin molecule, transport the metal to the cytosol for safe sequestration in a larger complex such as ferritin or 'paraferritin'.
