“…The K/Na balance is regarded to be important for people who take diuretics, to control hypertension and suffer from excessive excretion of potassium (Cutler 2006; Zillich et al 2006). Elements are also important as constituents of bones, teeth, soft tissues, hemoglobin, muscle, blood, and nerve cells, and are vital for overall mental and physical well being (Miyake et al 2005; Kuda and Ikemori 2009). …”

This study pointed to the assessment of the chemical composition (F, Ca, Mg, Na, K, Fe, Mn, Zn, Cu, Ni, Co, Cr, Cd, and carbohydrate) of different marine seaweeds (red, green, and brown) from the Egyptian Mediterranean Sea coast. The results showed that green seaweeds supplied better calcium sources than the red and brown ones. Also, red and brown seaweeds showed higher averages of Na and K than that in green species and these seaweeds could play an important role in the electrolyte balance in humans. On the other hand, green seaweeds gave the highest average carbohydrate concentration; thus, these green species could be used as a source of polysaccharides. Ion quotient values for almost seaweed species were between 1.4 and 4.0, so they can reduce hypertension, preeclampsia, and heart disease in human beings. Interestingly, the calculated hazard quotient of elements was below 1. Accordingly, these seaweed species were of high quality and safety and might be used in the field of nutrition.

Zinc plays a central role in skin integrity via barrier and immune mechanisms and may also be relevant in the pathogenesis of atopic dermatitis (AD). However, little is known about the relationship between zinc and AD. We performed a systematic review to determine (i) the association between zinc levels or zinc deficiency and AD and (ii) the efficacy of oral zinc supplementation in the treatment of AD. We searched PubMed, Scopus, Web of Science and article references for observational studies on zinc levels or zinc deficiency in participants with AD vs. controls and for randomized control trials (RCTs) on zinc supplementation in AD. For observational studies, we calculated pooled standardized mean differences (SMDs) or odds ratios (ORs) along with 95% confidence intervals (CIs) using a random effects model. We included 14 observational studies and two RCTs. The pooled SMD demonstrated significantly lower serum (SMD 0.66, 95% CI 0.21–1.10, P = 0.004), hair (SMD 0.95, 95% CI 0.38–1.52, P = 0.001) and erythrocyte (SMD 0.95, 95% CI 0.38–1.52, P = 0.001) zinc levels in participants with AD compared to controls. Pooled unadjusted data from three studies showed a non‐significant increased odds of AD in those with zinc deficiency compared with those without zinc deficiency (OR = 1.50, 95% CI 0.71–3.16, P = 0.28). One RCT of oral zinc supplementation among AD patients with zinc deficiency showed improvement in extent and severity of AD, while another RCT among all AD patients showed no significant improvement. All the studies were of low or moderate quality. We conclude that low serum, hair and erythrocyte zinc levels are associated with AD. However, the poor quality of included studies makes interpretation of these results problematic. High‐quality observational studies are needed to confirm the association between low zinc levels and AD, and RCTs are required to evaluate the merit of zinc supplementation for the treatment or prevention of AD.

“…Nevertheless, epidemiological information concerning the effects of seaweed consumption has been scarce. Inverse associations have been reported between seaweed consumption and stomach cancer [2], colorectal cancer [3], allergic rhinitis [4], mortality from all causes, pancreatic cancer, lung cancer, kidney cancer, and cerebrovascular disease [5], breast cancer [6], and elevated blood pressure [7], while positive associations have been shown between seaweed consumption and prostate cancer [8], upper aerodigestive tract cancer [9], mortality from colon cancer [5], metabolic syndrome [10], and thyroid cancer [11]. …”

BackgroundSeaweed is a popular traditional food in Japan and is a rich source of bioactive metabolites. The neuroprotective properties of seaweed have attracted attention; to date, however, there has been no epidemiological evidence regarding the relationship between seaweed consumption and depression. The current cross-sectional study investigated the association between seaweed consumption and depressive symptoms during pregnancy in Japan.MethodsStudy subjects were 1745 pregnant women. Depressive symptoms were defined as present when subjects had a Center for Epidemiologic Studies Depression Scale score of 16 or higher. Dietary consumption during the preceding month was assessed using a self-administered diet history questionnaire. Adjustment was made for age; gestation; region of residence; number of children; family structure; history of depression; family history of depression; smoking; secondhand smoke exposure at home and at work; job type; household income; education; body mass index; and intake of fish and yogurt.ResultsThe prevalence of depressive symptoms during pregnancy was 19.3%. After adjustment for possible dietary and non-dietary confounding factors, higher seaweed consumption was independently associated with a lower prevalence of depressive symptoms during pregnancy: the adjusted odds ratios (95% confidence intervals) for depressive symptoms during pregnancy in the first, second, third, and fourth quartiles of seaweed consumption were 1 (reference), 0.72 (0.51 − 1.004), 0.71 (0.50 − 1.01), and 0.68 (0.47 − 0.96), respectively (P for trend = 0.03).ConclusionsThe present results suggest that seaweed consumption may be inversely associated with the prevalence of depressive symptoms during pregnancy in Japanese women.
