According to Postdoctoral Researcher Maria Lankinen from the University of Eastern Finland, the findings warrant speculation on whether the recommended intake of linoleic acid - as well as maybe other obese acids, every bit good - should last tailored to jibe a person's genes.
"However, farther enquiry is needed earlier nosotros tin brand whatever recommendations based on genes," Postdoctoral Researcher Lankinen says.
The FADS1 factor regulates the body's obese acid metabolism as well as also plays a purpose inward glucose metabolism. Influenza A virus subtype H5N1 person's diet, inward turn, has a major acquit on on the concentrations of unlike obese acids inward the body. Linoleic acid is institute inward plant-based oils, nuts as well as seeds, as well as it is the nearly mutual polyunsaturated omega half-dozen obese acid. Influenza A virus subtype H5N1 high intake as well as high levels of linoleic acid inward the blood lead maintain been associated amongst a reduced adventure of type 2 diabetes as well as cardiovascular disease. On the other hand, however, the metabolites of linoleic acid tin mediate inflammation, which is why a high intake of linoleic acid is regarded every bit a plausible constituent contributing to low-grade inflammatory state. According to the newly published study, these contradictory observations could last explained past times genetic differences.
The report explored whether dot mutations inward rs174550 of the FADS1 factor modify the effects of linoleic acid on serum obese acid composition as well as on fasting glucose, insulin as well as CRP levels. These were analysed inward to a greater extent than than 1,300 middle-aged men participating inward the METSIM (Metabolic Syndrome inward Men) Study. In addition, threescore men participated inward the FADSDIET intervention for carriers of ii unlike factor variants. Over the course of report of 4 weeks, they supplemented their daily diet past times 30-50 ml of linoleic acid rich sunflower oil. Selecting the participants on the footing of their genes makes this a unique enquiry setting, which provides data on the interactions of diet amongst genes.
The findings dot that the effects of linoleic acid on the human trunk are largely subject on which variant of the FADS1 factor a individual is carrying. This has an consequence on, for example, how effectively a linoleic acid supplement tin lower fasting glucose levels. Moreover, depending on the factor variant, increased intake of linoleic acid tin brand a person's CRP levels become either upward or down. The FADS1 factor variant also had an consequence on the levels of inflammation mediators, which are created from the metabolites of linoleic acid as well as other omega half-dozen obese acids.
The report was conducted inward collaboration amongst Karolinska Institutet, as well as the findings were published inward the American Journal of Clinical Nutrition.
