Zinc deficiency is defined either as insufficient zinc to meet the needs of the body, or as a serum zinc level below the normal range. However, since a decrease in the serum concentration is only detectable after long-term or severe depletion, serum zinc is not a reliable biomarker for zinc status. [ 1 ]
Zinc-rich foods include beef, poultry, pumpkin seeds, fortified breakfast cereals, and seafood (in fact, oysters contain more zinc than any other food). Because zinc is found in so many foods ...
Normal potassium levels are between 3.5 and 5.0 mmol/L (3.5 and 5.0 mEq/L) with levels below 3.5 mmol/L defined as hypokalemia. [21] [28] It is classified as severe when levels are less than 2.5 mmol/L. [21] Low levels may also be suspected based on an electrocardiogram (ECG). [21] Hyperkalemia is a high level of potassium in the blood serum. [21]
The authors suggest this difference might be due to how zinc is absorbed and metabolized in studies that look at blood versus urine levels or because earlier studies included smaller sample sizes.
A new study from researchers in Malaysia points out that low levels of zinc are associated with numerous health conditions, including cardiovascular disease, cancer, Alzheimer’s, diabetes, and ...
Micronutrient deficiencies are considered a public health problem worldwide. For over 30 years it has been estimated that more than two billion people of all ages are affected by this burden, [1] while a recently published study based on individual-level biomarker data estimated that there are 372 million children aged 5 years and younger, and 1.2 billion non-pregnant women of reproductive age ...
In blood plasma, zinc is bound to and transported by albumin (60%, low-affinity) and transferrin (10%). [10] Because transferrin also transports iron, excessive iron reduces zinc absorption, and vice versa. A similar antagonism exists with copper. [30] The concentration of zinc in blood plasma stays relatively constant regardless of zinc intake ...
