High Omega-6 Levels Tin Protect Against Premature Instruct Out

"Linoleic acid is the near mutual polyunsaturated omega-6 obese acid. We discovered that the higher the blood linoleic acid level, the smaller the endangerment of premature death," says Adjunct Professor Jyrki Virtanen from the University of Eastern Finland, reporting the findings inward the American Journal of Clinical Nutrition.
Although omega-6 polyunsaturated obese acids are known for their beneficial lawsuit on blood cholesterol levels, it has been speculated that they may growth the endangerment of several chronic diseases yesteryear promoting low-grade inflammation, with other things. The reasoning behind this speculation is that inward the human body, linoleic acid is converted into arachidonic acid (also an omega-6 obese acid) which, inward turn, is converted into diverse inflammation-promoting compounds. However, omega-6 obese acids besides growth the production of anti-inflammatory compounds, as well as this is why it is challenging to produce upwards one's hear the associations of dietary factors with the endangerment of developing affliction only yesteryear focusing on their effects on affliction endangerment factors.
Ongoing at the University of Eastern Finland, the Kuopio Ischaemic Heart Disease Risk Factor Study, KIHD, determined the blood obese acid levels of 2,480 men betwixt 42 as well as sixty years of historic current at the onrush of the study, inward 1984-1989. During an average follow-up of 22 years, 1,143 men died of disease-related causes, as well as deaths due to an accident or other reasons were excluded from the study.
When the researchers divided the study participants into 5 unlike groups based on their blood linoleic acid level, they discovered that the endangerment of premature decease was 43% lower inward the grouping with the highest level, when compared to the grouping with the lowest level. Influenza A virus subtype H5N1 to a greater extent than detailed analysis of the causes of decease showed that a like association exists for decease due to cardiovascular diseases, every bit good every bit for decease due to another argue than cardiovascular diseases or cancer.
However, no association was observed for decease due to cancer. Similar, although slightly weaker, associations were besides observed for the blood arachidonic acid level. Another pregnant finding of the study is that the final result is rattling like regardless of whether the study participants suffered from cardiovascular diseases, cancer or diabetes at the onrush of the study.
The study backs upwards findings from before population-based studies which lead maintain linked a higher dietary intake of linoleic acid as well as a higher blood linoleic acid bird to a smaller endangerment of cardiovascular diseases as well as type two diabetes, without increasing the endangerment of cancer, for example. The observed association of arachidonic acid with a reduced endangerment of decease is a novel finding.
The blood linoleic acid bird is determined yesteryear a person's diet, as well as the principal sources of linoleic acid are vegetable oils, plant-based spreads, nuts as well as seeds. However, a person's diet volition send on his or her blood arachidonic acid bird exclusively a little.
