“…This positive effect of GTE and FO intake may reflect protection against MeHg-mediated oxidative damage. Furthermore, it is reported that EGCG protects neurons by suppressing production of NADPH oxidase-mediated reactive oxygen species and NADPH-d/nNOS expression, and that FO improves the fluidity of synaptic membranes (Wei et al, 2011;He et al, 2011;Suzuki et al, 1998;Yang et al, 2011;Hashimoto et al, 2006). Furthermore, Grotto et al (2011) agree that the protective effects of FO during MeHg exposure may be related to its anti-inflammatory effects.…”

Male mice (4 months old) were fed green tea extract-(GTE; 0.25% w/w) and/or fish oil-(FO; 5% w/w) containing diets with 8 ppm methylmercury (MeHg) chloride for 4 months to investigate the effects of simultaneous intakes on brain functions, antioxidant defenses against MeHg, and MeHg accumulation in tissues. In mouse maze tests, intake of GTE or FO significantly improved the learning ability of MeHg-exposed mice. GTE and FO also significantly decreased liver and brain catalase activities in MeHg-exposed mice. Total Hg concentrations in muscle were significantly lowered by dietary GTE and FO in the MeHgexposed group, though no remarkable differences were observed in the brain. These data indicate that simultaneous intake of GTE and FO effectively prevents MeHg-mediated oxidative stress and reduces the effects of Hg exposure with fish consumption.Keywords: fish oil, green tea, methylmercury, ascorbic acid, thiobarbituric acid reactive substances *To whom correspondence should be addressed. E-mail: nshinya@affrc.go.jp IntroductionFish contains several nutrients that are beneficial to human health. However, fish has been known to contain hazardous components such as methylmercury (MeHg), which has been linked to decreased neuropsychological function and increased risk of cardiovascular diseases (Choi et al., 2009;Virtanen et al., 2007). In contrast, n-3 polyunsaturated fatty acids (PUFA) contained in fish improve brain function (Guesnet et al., 2011;Mourek and Mourek, 2011) and reduce the risk of cardiovascular diseases (Cottin et al., 2011). Some reports indicate that dietary fat can influence oxidative DNA damage, nephrotoxicity, and steroidogenic enzyme activities after MeHg exposure (Grotto et al., 2011;Jin et al., 2008Jin et al., , 2009McVey et al., 2008). However, the human diet varies widely, and some reports have shown that foodstuffs other than seafood may also prevent MeHg toxicity and accumulation (Abdalla et al., 2010;Farina et al., 2005;Lee et al., 1999;Rowland et al., 1986;Sumathi et al., 2012). Therefore, daily fish consumption may alleviate relatively few health risks.In general, the Japanese drink a few cups of green tea every day, and often accompany sushi meals with green tea. Therefore, a close relationship exists between green tea and fish oil in the Japanese diet. Canuel et al. (2006) concluded that tea might accelerate the enterohepatic MeHg cycle and contribute to temporary MeHg bioamplification in the bloodstream. Green tea contains large quantities of polyphenols that have antioxidant effects and accelerate cadmium (Cd) excretion by forming chelates (Abib et al., 2011;Yu et al., 2007;Wang et al., 2012). Some studies indicate that green tea consumption reduces the risk of coronary heart disease (Bøhn et al., 2012;Chacko et al., 2010) and prevents agerelated neurodegeneration (Andrade and Assunção, 2012). Thus, these green tea polyphenol properties may be effective against MeHg toxicity.The aim of this study was to determine the interactive influence of fish oil and green tea on the effects o...

“…Improvements are observed in fatty acid composition, developmental and behavioural parameters in pigs (Cordoba et al, 2000;Rooke et al, 2000 and2001c) and in other species (Suzuki et al, 1998). In contrast, other studies have shown that supplementation has led to reduced growth in utero in pigs (Rooke et al, 2001c) and to reduced growth and development in postnatal life in humans and rats (Carlson et al, 1992 and1993;Saste et al, 1998;Amusquivar et al, 2000).…”

The role of dietary fat during early pregnancy in sows has not yet been fully established. The aim of the study was to determine the consequences of altering the fatty acid profile of sow diets during the first half of gestation; oils of different fatty acid composition were chosen as energy supplements to provide diets with different fatty acid profiles. A group of 48 multiparous sows were used to evaluate the effects of supplemental feeding during the first 60 days of gestation (term ≈ 115 days). Sows were allocated (eight per treatment) to either 3 kg/day of commercial sow pellets (control; C) or an experimental diet consisting of 3 kg/day of commercial sow pellets supplemented with 10% extra energy in the form of excess pellets (E), palm oil (P), olive oil (O), sunflower oil (S) or fish oil (F). Differential effects were observed with respect to the fatty acid profile of the diet during the first half of gestation. P sows gave birth to the largest litters. Both P and O supplementation of the maternal diet resulted in heavier piglets at birth, after correction for differences in litter size. P piglets possessed the most fat at birth and remained fatter throughout the pre-weaning period; in contrast, the offspring of O sows contained the least fat throughout life (0 to 140 days of age). The offspring of F sows exhibited improved growth performance during the neonatal period. In conclusion, altering the fatty acid profile of sow diets during the first half of gestation has long-term consequences for the growth and development of their offspring.

“…The significance of sea foods has gained increasing attention worldwide particularly due to their high contents of n-3 polyunsaturated fatty acids, such as eicosapentaenoic acid (EPA; C20:5 (n-3)) and docosahexaenoic acid (DHA; C22:6 (n-3)) [3]. In fact, fatty acids have a particular importance in fish since their consumption has often been reported to induce several beneficial effects, including the reduction of cardiovascular diseases and improvement of learning abilities [4,5].…”

This study was undertaken to determine the effects of two appropriate household cooking methods, steam and microwave-cooking, on proximate chemical composition, energetic values, fatty acids profiles, texture profile analysis and bacteriological characteristics of zebra blenny (Salaria basilisca) fillets from Tunisian coasts. The nutritional values of the fish fillets were improved after the two cooking methods. Fatty acid profiles of zebra blenny fillets showed that Polyunsaturated Fatty Acids (PUFA) contents are higher than those of Saturated Fatty Acids (SFA). They showed also differences between cooking methods. All textural attributes of zebra blenny fillets were influenced by cooking process. Microbiological changes [Total viable counts (TVC), Lactic Acid Bacteria (LAB), Enterobacteriaceae, Listeria monocytogenes as well as fungi] were monitored as a function of treatment and storage time. On day 5 of storage under refrigeration the number of micro-organisms is always minimal for samples heat treated comparing with those raw.
