This Journal Loves Zinc

From eNewsletter 8/4/2026

DID YOU KNOW that seven recent studies, all published in Frontiers in Nutrition, laud the myriad benefits of zinc or lack thereof. It is apparent that this journal is doing its due diligence on zinc!

Atrial Fibrillation

Zinc deficiency may serve as an important independent risk factor for incident AFib.

Dementia

Zinc deficiency represents an independent, modifiable risk factor for new-onset dementia.

Intracerebral Hemorrhage

Zinc deficiency is a novel, independent, and potentially modifiable risk factor for ICH.

Oral Cavity and Teeth

One study found that zinc deficiency impairs antioxidant defenses for oral cavity cancer. Another study found that dietary zinc intake reduces the risk of hypertension in periodontitis patients.

COVID-19

Zinc deficiency was observed in 28.6% of children with COVID-19 and was not dependent on age.

Cognitive Impairment

Higher plasma zinc levels and higher zinc/copper ratio were associated with lower odds of mild cognitive impairment in type 2 diabetes patients, while higher copper levels alone increased the risk.

NOTE: managing your zinc/copper ratios, with zinc being higher than copper (but you still need some copper), is essential.
