In July 2013, using data and plasma collected in the Selenium and Vitamin E Cancer Prevention Trial (SELECT), results were shown consistent with prior results of the controversial 2011 Prostate Cancer Prevention Trial. Both trials exhibited unexpected associations: 1) Fish oil and fish oil’s DHA significantly increase prostate cancer in men; in particular, high grade prostate cancer; 2) Harmful...

Although fish and fish oil supplements have been touted for their many benefits, especially in the treatment of cardiovascular disease, recent headlines have suggested that they might be linked to an increased risk of prostate cancer. P&T takes a closer look behind the mixed messages.

This study evaluated the suitability of canola oil as a source of supplemental dietary lipid for rainbow trout. Triplicate groups of the 30 fingerlings held under identical culture conditions were fed twice daily by iso-nitrogenous, iso-calorific and iso-lipidic diets for eight weeks. Experimental diets consisted of 30.3% protein, 18.7 kJg-1 energy and 16.7% lipid from fish oil (FO), canola oil...

Deep-fat frying performed at high temperatures under atmospheric pressure is a common method of preparing dishes in Senegalese culinary practices. This operation can lead to deterioration of physical, chemical, nutritional and sensory properties of oil, which affects its frying performance. It also results in the production of volatile products such as aldehydes and non volatile fraction which ...

This study assessed the relative contributions of host genetics and diet in shaping the gut microbiota of rainbow trout. Full sibling fish from four unrelated families, each consisting of individuals derived from the mating of one male and one female belonging to a breeding program, were fed diets containing either vegetable proteins or vegetable oils for two months in comparison to a control d...

In this study, plant oils of Hypericum perforatum, Sesamum indicum, Nigella sative were investigated for their in vitro antibacterial activity against Vibrio anguillarum and Lactococcus garvieae. Antibacterial activity was found to show with oil of Nigella sative. It was determined formed on the diameter of inhibition (inhibition zone: 18 mm) of the oil against Vibrio anguillarum and Lactococcu...

The potential of microalgae biomass production for low-cost commodities—biofuels and animal feeds—using sunlight and CO2 is reviewed. Microalgae are currently cultivated in relatively small-scale systems, mainly for high value human nutritional products. For commodities, production costs must be decreased by an order of magnitude, and high productivity algal strains must be developed that can b...

Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) present in fish oils have been ascribed as having significant antithrombotic and antiatherosclerotic effects. Vascular smooth muscle cell (SMC) proliferation plays an important role in the pathogenesis of atherosclerosis and restenosis. Recent studies have indicated that serotonin at concentrations present at sites of vascular injury st...

Although the fish-derived, long-chain omega-3 fatty acids (n-3 FA) may be considered “gifts from the sea” for cardiovascular health, the role of the land (or plant) -based n-3 FA -linolenic acid (ALA) has been less clear. ALA is the 18-carbon, 3-double bond (C18:3n-3) precursor to eicosapentaenoic acid (EPA; C20:5n-3) and docosahexaenoic acid (DHA; C22:6n-3), the latter 2 being the predominant ...

Interest is increasing in the potential cardioprotective role of -3 (n-3) fatty acids (FAs). Most of the evidence supporting this hypothesis has been derived from studies of the longer-chain members of the n-3 family, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), found in fish oils.1 The value of the shorter-chain cousin, -linolenic acid (ALA), found in certain plant oils (flaxsee...
