锌缺乏可导致高血压 Zinc deficiency can cause hypertension

Saturday May 4, 2019 (jkzx.com) — 一项新研究发现，低血清锌水平可能会增加人体高血压或高血压的风险。这是因为锌缺乏会对肾脏如何处理钠产生负面影响。

在两组小鼠的研究中，一组有足够的锌和另一组缺乏，埃默里大学的研究人员发现缺锌小鼠出现高血压并降低尿液中的钠含量。

然后研究人员给一小群锌缺乏的小鼠喂食含锌丰富的饮食，发现膳食补充锌会降低血压并增加尿钠水平。

该研究结果发表在美国生理学 – 肾脏生理学杂志上，表明锌缺乏会增加肾钠再吸收，从而增加血压。

牡蛎，螃蟹，黑肉火鸡和鸡肉等海鲜是锌的最佳来源。可用于预防锌缺乏的锌补充剂包括葡萄糖酸锌，乙酸锌，吡啶甲酸锌和硫酸锌。

Zinc deficiency can cause hypertension

A new study finds low serum levels of zinc may raise the risk of high blood pressure or hypertension in humans. This is so because zinc deficiency can have a negative impact on how the kidney process sodium.

During the study of two groups of mice, one with sufficient zinc and another deficient, researchers from Emory University found that mice with zinc deficiency developed high blood pressure and decreased sodium levels in urine.

Then the researchers fed a small group of zinc deficient mice with a zinc rich diet and found that dietary supplementation with zinc lowered blood pressure and increased the urinary sodium levels.

The results of the study, which was published in the American Journal of Physiology-Renal Physiology indicate that zinc deficiency increases renal sodium re-adsorption which boosts blood pressures.

Seafood like oysters, crab, dark meat turkey and chicken are among the best sources of zinc. Zinc supplements that can be used to prevent zinc deficiency include zinc gluconate, zinc acetate, zinc picolinate, and zinc sulfate.
