Selenium is an essential trace element in vertebrates, but there is a narrow concentration range between dietary requirement and toxicity threshold. Although a great deal is known about the biochemistry of Se from a nutritional perspective, considerably less attention has been focused on the specific biochemistry of Se as an ...

OBJECTIVE: The purpose of this study was to identify self-identities among mainstream and natural foods shoppers and the relationship of these self-identities to soy consumption and BMI. We hypothesized that soy consumers (SCs) would have lower BMIs than non-consumers (NCs) and that persons who self-identify themselves as SCs, natural foods, ...

Contributions of fish and other foods to variance of selenium and mercury status were studied in British adults. Plasma and red-cell selenium and whole-blood mercury concentrations were measured during the National Diet and Nutrition Survey of Adults aged 19-64 years in mainland Britain, 2000-2001 (n = 1216). Food intake was ...

BACKGROUND: Socio-economic factors may affect diet quality, perhaps differentially across gender and ethnicity. The mechanism of this association is still largely unknown. OBJECTIVES: We examined the independent effects of socio-economic status (SES), perceived barrier of food price (PBFP) and perceived benefit of diet quality (PBDQ) on diet quality indicators and ...

Background Tuberculosis is a world wide pandemic and a major problem for people in low income countries. The intracellular infection has a bidirectional link with under nutrition, and wasting is a common symptom of the disease. Wasting in tuberculosis patients is associated with the severity of lung disease, low serum ...

Selenium occurs as inorganic selenite or selenate and in organic forms in plants and other organisms used for food. The human selenoproteome consists of 25 selenoproteins. The main groups are glutathione peroxidases 1-5, iodothyronine deiodinases 1-3, thioredoxin reductases, selenoprotein P (SelP), and other proteins mostly with unknown function. In selenoproteins ...

BACKGROUND: An ITN intervention was initiated in three predominantly rural districts of Eastern Province, Zambia, that lacked commercial distribution and communication infrastructures. Social marketing techniques were used for product and message development. Public sector clinics and village-based volunteers promoted and distributed subsidized ITNs priced at 2.5 dollars per net. A ...

Asian populations including Koreans are assumed to have a higher isoflavone intake due to the higher consumption of soybean. However, it is difficult to estimate isoflavone intake because there is no isoflavone database in Korea. In this study, an isoflavone database was established with systematic review. Literature with analytical values ...

Soya, cultivated for more than 3000 years, is both a drug and a food product. It has numerous nutritional benefits, given by its content of isoflavones, essential amino acids, fibers, poly-unsaturated fatty acids, vitamins and minerals. The use of soy reduces the risk of cardiovascular diseases: it has an antioxidant ...

We examined transgenerational retention and maternal transfer of selenium (Se) in three consecutive generations (F0, F1, and F2) of Daphnia magna. The F0 generation was exposed to dietary selenium (as selenite) only, and the F1 and F2 generations received only the maternally derived selenium from F0 and F1, respectively. Algal ...

Relationships between Se and Hg in erythrocytes, and between these indices and intakes of fish and other foods, were studied as an adjunct to the British National Diet and Nutrition Survey (NDNS) of young people aged 4-18 years. Hg was measured in 965 packed erythrocyte samples by inductively coupled plasma ...

We examined the effect of different food qualities, in terms of the C:N:P content, on the collembolan Hypogastrura viatica. We hypothesised that (faster growing) juveniles would have higher demands for P and N than adults; this, however, was rejected by our experiments. There was no difference between the elemental compositions ...

7-Hydroxy-3-(4'-hydroxyphenyl)-chroman (S-equol) is a specific end-metabolite formed in the biotransformation of the dietary soy isoflavones daidzin and daidzein by intestinal bacteria. The frequency of equol production varies among individuals and populations, and it is suggested that the efficacy of soy foods differs depending on the ability of an individual to ...

Selenium uptake from food (assimilation efficiency) and dissolved phase (influx rate) as well as loss kinetics (efflux rate) were compared between two bivalves, Corbicula fluminea and Potamocorbula amurensis. The effects of salinity and temperature on these kinetic parameters for both clam species also were evaluated. The Asiatic clam, C. fluminea, ...

Some food products naturally contain phytoestrogens, but there are few in Western diets that are significant sources. The foods that are the most significant sources are soy beans, containing isoflavones, and flaxseed, which contains lignans. These foods have, however, until recently been relatively little used in Canada and the United ...

Plant lignans occur in many foods, with flaxseed presently recognized as the richest source. Some plant lignans can be converted by intestinal microbiota to the mammalian lignans, enterodiol and enterolactone, which may have protective effects against hormone-related diseases such as breast cancer. This study determined whether plant lignans in sesame ...

If soy isoflavones are to be effective in preventing or treating a range of diseases, they must be bioavailable, and thus understanding factors which may alter their bioavailability needs to be elucidated. However, to date there is little information on whether the pharmacokinetic profile following ingestion of a defined dose ...

A H2-based, denitrifying and sulfate-reducing membrane-biofilm reactor (MBfR) was shown to be effective for removing selenate (Se(VI)) from water or wastewater by reducing it to insoluble Se(0). When Se(VI) was first added to the MBfR, Se(VI) reduction--first to selenite (Se(IV)) and then mostly to Se(0)--took place immediately and then increased ...

Selenium (Se), an essential nutrient, is needed for activity of several important proteins. Additionally, the consumption of Se in amounts that exceed the Recommended Dietary Allowance (RDA) may protect against prostate and colorectal cancer. Supplemental Se may be acquired through the diet, but Se bioavailability depends on the source. Therefore, ...

Higher soy food intake has been hypothesized to be a major factor explaining the decreased breast cancer risk in Asian countries, compared to those regions of the world consuming predominantly Western-style diets. Consumption of soy isoflavones, particularly genistein, has received considerable attention as the soy component largely responsible for the ...

Selenium (Se) is an essential micronutrient, exhibiting a narrow margin between nutritionally optimal and potentially toxic concentrations. Egg-laying vertebrates at the top of aquatic food chains are most at risk in environments with elevated aqueous Se concentrations. The Elk River watershed in British Columbia, Canada receives effluents containing Se from ...

The effect of three plant lectins, soybean lectin (SBA), Japanese jack bean lectin (CGA), and wheat germ lectin (WGA), on the transport of various food factors, such as isoflavones, quercetin, dipeptides, and calcium ions, were investigated by use of an intestinal tract model, Caco-2 cell monolayers. The lectins increased the ...

The principal phyto-oestrogens (PO) in food are isoflavones, lignans, coumestans and prenylated flavonoids, with isoflavones and lignans being the most commonly found in UK diets. Until recently obtaining accurate data on the PO content of foods was hampered by lack of suitable analytical methods and validation techniques. Furthermore, although PO ...

There is substantial interest in the possible anticancer effects of soy foods. In part, this is because of the historically low incidence rates of breast and prostate cancer in Asia. Of the several putative soybean chemopreventive agents, isoflavones have received the most attention. Awareness of this research has led increasing ...

Soy foods and nutritional supplements are widely consumed for potential health benefits. It was previously shown that isoflavone-supplemented diets, which contained equal genistein equivalents, differentially stimulated mammary tumor growth in athymic mice based on the degree of processing. This paper reports plasma pharmacokinetic analysis and metabolite identification using the parental ...
