Cardiovascular and coronary heart diseases continue to be the leading causes of morbidity and mortality among adults in Europe and North America. Since the number of elderly people and therefore the number of chronic-inflammatory diseases rise, preventive therapies become more important. Within preventive strategies, nutrition plays a central role.
Cross-sectional studies suggested that omega-3 fatty acids, especially the very long-chain fatty acids Eicosapentaenoic acid (EPA, C20:5ω3) and Docosahexaenoic acid (DHA, C22:6ω3), are protective against cardiovascular and coronary heart diseases. Their cardio protective potential is based on their positive effects on blood lipids, vascular tonus and blood clotting. A number of controlled clinical trials have shown that EPA and DHA supplementation lower fasting and postprandial plasma concentrations of triglyceride-rich lipoproteins and their remnants. Biochemical research revealed numerous metabolic effects of EPA and DHA, ranging from their effects on membrane fluidity to the modification of the eicosanoid profile.
However, only a few human clinical trials examined the regulative effects of DHA and EPA supplementation on gene expression. Furthermore, to our knowledge no published research data is available dealing with the effect of these fatty acids on gene expression in subjects with hypertriglyceridemia in comparison to healthy subjects. Such findings are of great concern due to hints that especially people with hypertriglyceridemia benefit from the triglyceride lowering effect of EPA and DHA supplementation. Presently it is not well-established if the gene regulative potential of EPA and DHA in these persons differs from healthy persons. These findings could help to understand the differences in the metabolic effects of EPA and DHA in healthy vs. hypertriglyceridemic persons, which have a greater risk for cardiovascular and coronary diseases. Finally, these data could contribute to a knowledge basis for targeted strategies in preventive therapies with the very long-chain omega-3 fatty acids EPA and DHA.

Syrup made from corn used widely in foods and beverages as a cheaper alternative sweetener to SUCROSE (common table sugar). It is generated by enzymatic processing of natural corn syrup to produce a liquid most widely composed of 42 or 55% FRUCTOSE, GLUCOSE, and various POLYSACCHARIDES.
Oil from ZEA MAYS or corn plant.
Fish of the genera ONCORHYNCHUS and Salmo in the family SALMONIDAE. They are anadromous game fish, frequenting the coastal waters of both the North Atlantic and Pacific. They are known for their gameness as a sport fish and for the quality of their flesh as a table fish. (Webster, 3d ed).
Food products manufactured from fish (e.g., FISH FLOUR, fish meal).
The most diversified of all fish orders and the largest vertebrate order. It includes many of the commonly known fish such as porgies, croakers, sunfishes, dolphin fish, mackerels, TUNA, etc.
