Analysis of clays
from Africa, Sardinia and California reveals that clay can provide a variety of macro - and trace minerals including calcium, phosphorus, magnesium, iron and
zinc.2 Clay also contains aluminum, but silicon, present in large amounts in all clays, prevents
absorption of this toxic metal and actually helps the body eliminate aluminum that is bound in the tissues.3
Taking iron supplements in conjunction with meals may also prevent the
absorption of
zinc from food.
For example, it decreases magnesium
absorption by 60 percent and
zinc by 20 percent, and too much phytic acid can cause minerals to be leached
from your bones and teeth.»
Iron, magnesium and copper are all blocked
from absorption, and
zinc is also inhibited.
Because
zinc absorption is inhibited by the presence of food (notably foods containing either phytates, such as high fiber whole grains, or casein, a milk protein) it is often suggested to take
zinc supplements away
from meals.
The bioavailability of
zinc from vegetarian diets is lower than
from non-vegetarian diets because vegetarians do not eat meat, which is high in bioavailable
zinc and may enhance
zinc absorption.
When
zinc deficiency does occur, it is usually due to inadequate
zinc intake or
absorption, increased losses of
zinc from the body, or increased requirements for
zinc [26,27,34].
In particular, high
zinc intakes impair
absorption of copper, a nutrient we already struggle to obtain
from our diets.
Gastrointestinal surgery and digestive disorders (such as ulcerative colitis, Crohn's disease, and short bowel syndrome) can decrease
zinc absorption and increase endogenous
zinc losses primarily
from the gastrointestinal tract and, to a lesser extent,
from the kidney [2,26,35,36].
To minimize these episodes of copper discharge, Gittleman recommends emphasizing nutrients which have an antagonizing action to copper, that is, they reduce its
absorption or aid in binding it for excretion
from the body.106 The most important of these, of course, is
zinc itself, as obtained
from the land - based proteins mentioned above.
In one report it is noted that Vitamin B6 is crucial for the proper
absorption of
Zinc from the intestines, but it [is] also thought to have some hair loss preventing properties, such as the ability of vitamin B6 to boost * oxygen supply to the scalp.
Don't buy a cheap and nasty
zinc oxide supplement
from the supplement store because the
absorption is terrible.
For those suffering
from lead or other heavy metal poisoning, a protective diet that avoids processed foods and emphasizes the central components of a nutrient - dense and antioxidant - rich WAPF - style diet is essential (see sidebar).21 Nutritional status shapes susceptibility to lead toxicity in important ways, affecting lead's intestinal
absorption; its mobilization, distribution and retention in the body; and excretion.22 Because oxidative stress is a likely mechanism explaining some of lead's toxic actions, some investigators have begun to explore whether natural antioxidants and trace minerals may help mitigate lead - induced cell damage.17 Specifically, researchers in Spain found that administration of vitamins A, B6, C and E along with
zinc modulated some of the negative effects of lead exposure in rat pups, confirming the influence of nutritional factors on health outcomes following lead exposure.17 Vitamin D also should be a major component of a protective diet.
Taken this way, its metal - binding capacity is unlikely to hinder the
absorption of needed minerals such as calcium, magnesium and
zinc, which we take in
from our food at mealtimes or
from supplements during the day.
Sandstrom B, Kivisto B, Cederblad A.
Absorption of
zinc from soy protein meals in humans.
Absorption of
zinc from wheat products fortified with iron and either
zinc sulfate or
zinc oxide.
