"Zinc absorption" refers to the process by which the body takes in or absorbs zinc, an essential mineral that is important for various bodily functions.
Full definition
These foods
blocks zinc absorption and contribute to weakened immunity, added inflammation and the increased likelihood of bacteria overgrowth.
Animal studies show that excessive dietary intake of calcium
decreases zinc absorption, however, studies have not been done in humans.
Taking supplements containing 25 mg of elemental iron, particularly on an empty stomach, can cause nausea and constipation and
reduce zinc absorption.
Your body absorbs zinc from animal products more readily, largely because these foods also contain amino acids that
promote zinc absorption.
Coffee seems to have only a tiny effect
on zinc absorption (luckily, because zinc is extremely important), and no effect on magnesium.
Other substances in foods or drinks (like caffeine and phytates) can
inhibit zinc absorption so if zinc foods or supplements are consumed within a few hours of foods containing these supplements, absorption may be inhibited.
Similarly, vegetarian diets reduce
zinc absorption by 35 % compared to omnivorous diets due to phytate content, such that vegetarians may require up to 50 % more zinc than omnivores (58).
Sandstrom B, Almgren A, Kivisto B, Cederblad A. Effect of protein level and protein source on
zinc absorption in humans.
Jalla S., Steirn M. E., Miller L. V., Krebs N. F. Comparison
of zinc absorption from beef vs iron fortified rice cereal in breastfed infants.
Phytates found in soy products interfere with
zinc absorption more completely than with other minerals.19 Zinc deficiency can cause a «spacy» feeling that some vegetarians may mistake for the «high» of spiritual enlightenment.
Adding small amounts of animal proteins to legume meals can significantly increase zinc absorption [36].
Soaking beans until they sprout before cooking reduces phytate content and thus increases
zinc absorption from beans.
My question is... if my daughter followed a wapf diet does she need to supplement her baby with more iron and if so can desiccated liver be mixed in with her breast milk (for a bottle feed) to supplement her, without affecting other processes in the body
like zinc absorption.
For instance, this study found that the phytic acid in maize inhibited
zinc absorption massively, while this one commented that «phytic acid is the main known inhibitor of zinc».
Zinc Select ® also provides a modest 50 mg of Betaine HCl to help gently lower gastric pH levels and
facilitate zinc absorption whether the product is taken with or without food.
Zinc Select ® is a state - of - the - art, synergistic formula combining two researched, well - absorbed forms of chelated zinc with a blend of digestive herbs and bitters, plus Betaine HCl, to help
optimize zinc absorption and tolerability.
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.
There's another hitch with phytic acid, a natural mineral binder which
prevents zinc absorption, which is found in seeds and nuts and all five of those foods.
Sorry, those Brazil nut - crusted oysters, while delicious, might be a bad idea
for zinc absorption.
Coudray and colleagues (1997) showed no effect of isolated viscous inulin or partly viscous sugar beet fibers on either iron or
zinc absorption when compared to a control diet.
Inorganic iron and calcium supplements may decrease
zinc absorption as well as alcohol, infection and surgery.
Zinc from animal foods is absorbed better than from plant foods, which contain phytates that reduce
zinc absorption in the small intestine.
Soybeans have very high levels of a form of phytic acid that is particularly difficult to neutralize and which interferes
with zinc absorption more completely than with other minerals.
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.
However, large amounts of supplemental iron (greater than 25 mg) might decrease zinc absorption [2,78].
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].
Taking too much Iron through supplements can
reduce zinc absorption.One of the potential causes of gastrointestinal upset is the fact that consuming too much iron can reduce zinc absorption and lead to a zinc deficiency (24).
Have had all the suggested tests done with the following results: TSH: less than.01 Free T3: 4.8 Free T4: 15.3 Iodine: 10 mcg Iron: 12.3 Cortisol: 268 Selenium: 1.92
Zinc absorption: 891 Cooper: ok NOW WHAT?
Supplemental iron (particularly when administered in solution or as a separate supplement rather than incorporated into a meal) can interfere with
zinc absorption.
Alcohol and some prescription meds may also inhibit
zinc absorption.
Moreover,
zinc absorption is inhibited by plant compounds such as phytate, oxalate, polyphenols and fiber, and enhanced by compounds present in meat.
This zinc absorption claim is everywhere, but there's no hard data supporting it.
Copper, iron, and
zinc absorption, retention and status were all examined young women with relation to their vitamin B6 status.
Most of these points can be refuted upon closer inspection, for example, soaking and fermenting soy minimises the phytic acid in it, an acid that interferes with iron and
zinc absorption.
