“…Sea spaghetti RP partially blocked the effect of the hypercholesterolemic agent included in the CholSS diet. Sea spaghetti is rich in soluble fibers [19] and polyphenols [10,28], all of which are factors that are thought to exert hypocholesterolemic effects. Sodium alginate, funoran, porphyran, and carrageenan have been shown to interact with dietary cholesterol to facilitate its excretion, while dietary agar was almost inactive [29].…”

Background: Inclusion of seaweeds in restructured pork (RP) would improve meat health properties. Aim: The aim was to determine the effects of RP containing Himanthalia elongata on growth, organ weight, cholesterolemia, and expression of lipoprotein lipase (LPL), acetyl CoA carboxylase (ACC), fatty acid synthase (FAS), and hormone-sensitive lipase (HSL) in adipose tissue of Wistar rats. Methods: The control group (C) consumed control RP, and the seaweed group (SS) consumed RP with 5% Himanthalia elongata. Animals on cholesterol-enriched diets (CholC, CholSS) consumed their corresponding basal diets with supplementary cholesterol (2.43%) plus cholic acid (0.49%) as hypercholesterolemic agents. Results: Seaweed inclusion did not modify cholesterolemia but reduced (p < 0.01) the hypercholesterolemic effect of dietary cholesterol plus cholic acid. CholC rats presented lower (p < 0.05) adipose fat and weight than C rats. Cholesterol feeding affected HSL, ACC, and FAS expression (p < 0.05), while alga consumption influenced HSL and ACC (p < 0.05). LPL was not significantly affected by both factors. CholSS rats showed decreased HSL and FAS (p < 0.05) but increased ACC (p < 0.05) expression compared with CholC rats. Conclusion:Himanthalia RP partially blocked the dietary hypercholesterolemic effect and changed the lipogenic/lipolytic enzyme expression, reducing the wasting effect of hypercholesterolemia on adipose tissue in rats.

“…The mean contents of arsenic, Pb, Cd, and Hg in Porphyra sp. that were produced in Korea, Japan and Italy were assessed as harmless (47,48) . However, arsenosugars detected in Porphyra seaweed were metabolised to dimethylarsinic acid in human bodies that is more toxic than arsenosugars (49) .…”

“…However, arsenosugars detected in Porphyra seaweed were metabolised to dimethylarsinic acid in human bodies that is more toxic than arsenosugars (49) . Moreover, brown seaweeds are known as primary accumulators for arsenic (47,48,50) . Thus, the heavy metal contamination of seaweed should be controlled and considered to protect consumers from potential health risks.…”

A case–control study on seaweed consumption and the risk of breast cancer

Gim (Porphyra sp.) and miyeok (Undaria pinnatifida) are the seaweeds most consumed by Koreans. We investigated the association between the intake of gim and miyeok and the risk of breast cancer in a case -control study. Cases were 362 women aged 30 -65 years old, who were histologically confirmed to have breast cancer. Controls visiting the same hospital were matched to cases according to their age (SD 2 years) and menopausal status. Food intake was estimated by the quantitative FFQ with 121 items, including gim and miyeok. Conditional logistic regression analysis was used to obtain the OR and corresponding 95 % CI. The average intake and consumption frequency of gim in cases were lower than in controls. The daily intake of gim was inversely associated with the risk of breast cancer (5th v. 1st quintile, OR, 0·48; 95 % CI, 0·27, 0·86; P for trend, 0·026) after adjustment for potential confounders. After stratification analysis was performed according to menopausal status, premenopausal women (5th v. 1st quintile, OR, 0·44; 95 % CI, 0·24, 0·80; P for trend, 0·007) and postmenopausal women (5th v. 1st quintile, OR, 0·32; 95 % CI, 0·13, 0·80; P for trend, 0·06) showed similar inverse associations between gim intake and the risk of breast cancer after an adjustment for potential confounders except dietary factors. Miyeok consumption did not have any significant associations with breast cancer. These results suggest that high intake of gim may decrease the risk of breast cancer.

“…People have increased the use of seaweeds in different industries (cosmetic, pharmaceutical and fertilizers), it is also known for its contribution to the nutritional requirement of the human diet (Parada, 2007).Seaweed is an ideal source of fiber, polyunsaturated fatty acids, vitamins, proteins and minerals (Shaefer, 2007). Seaweed bioaccumulates essential elements such as Co, Cr, Mo, Ni, Se, V, Mg, Ca, Fe and I at higher rates than land vegetation (Rao, 2007).…”

The purpose of the study: In this work, the nutritional and elemental analysis of seaweeds in Northern Samar is analyzed. Methodology:The seaweeds of Northern Samar are collected from intertidal zone, and it was brought back to the College of Science for taxonomic identity. The nutritional and elemental content of the seaweeds were determined Main findings: Based on the results obtained a total of 39 species belonging to eighteen (18) families of seaweeds were recorded from different coastal towns in Northern Samar, Philippines. The results revealed that for seaweeds with the economic value the nutritional and elemental content is comparable to the unknown seaweeds with no economic value. Implications:The results of bioavailability of nutrients of this study might be the basis that unknown seaweeds with no economic value can be used directly in the diet and promote health advantage.Originality/Novelty of study: The seaweeds of Northern Samar are not properly documented in comparison with other marine flora. The results demonstrated that some species of seaweeds collected in Northern Samar with no economic value could also accumulate non-essential elements. Further studies would surely be a great contribution to our local food and pharmaceutical industries.
