The idea of eating more saturated fats will increase our risk of heart disease is intended to be established in accordance with the most nutritional commentators. The fact is that you as disclosed not here, there is really any convincing evidence to support this claim. Three important exams recently could not find evidence demonstrating saturated fats cause heart disease. Getting doctors, dietitians, and Governments to release their understanding of this concept has not been easy. Sympathize, there was a time believed with all my heart fat saturated caused heart disease. Note that I write 'with all my heart'. My head I knew nothing, and the reason was simple: at that time had never intended to verify the facts. Such was the certainty that I had told the 'history of heart disease of saturated fat causes,' happens even to me to look at the evidence. When I did, was truly appalled at what I discovered.
I had another moment today, revelation in a study published online reading and due to appear in the next month the American clinical nutrition magazine Edition [1] .this study had followed more than 58,000 Japanese for a period of 14 years adults and assessed the relationship between his death intake and risk of a variety of ' cardiovascular ' saturated fat.
Advancing, back on some terminology. Cardiovascular disease is an umbrella term that covers essentially stroke or heart-related conditions. Heart-related causes of death include attacking the heart (heart attack), cardiac arrest (heart stop) and heart failure (when the heart becomes too weak to support life). Strokes come in two main types: ischemic and hemorrhagic. Ischemic strokes are the most common types of stroke and are caused by a blockage of one or more blood vessels in the brain.On the other hand, hemorrhagic stroke caused by bleeding in the cerebro.estos come in two main forms, 'intraparenchymal' and 'subarachnoid haemorrhage'.Well, enough of the technicalities.
For each of these conditions, the authors of the study compared to the risk of death to the intake of fats saturadas.Este is a summary of what they found:
Compared with those eating saturated fats at least, those eat more were found to:
To NO increased risk of death due to heart attack, heart failure or heart failure.
No increased risk of death due to a subarachnoid hemorrhage.
REDUCED risk of death due to bleeding intraparenchymal (52 percent reduced risk)
REDUCED risk of death due to ischaemic stroke (42 percent reduced risk)
REDUCED risk of death due to an accident (all types of squeegee stroke) stroke (31 percent reduced risk)
And wait for it ….
Increased intake of saturated fat were found to be associated with a REDUCED risk of death from CARDIOVASCULAR DISEASE (18 percent reduced risk)
Now, at least some of these findings should be no surprise to fans of literature científica.Sabemos that consistently saturated fat has not been linked to the risk of disease cardíaca.Además, several previous studies have linked higher intake of fat saturated with a lower risk of stroke, mainly stroke hemorrágico.Una theory here, presented by the authors, is that low levels of cholesterol (perhaps secondary to the low content of saturated fat intake) leads to thin and weak blood vessels in the brain (which are more prone to hemorrhages).
However, the fact that this study linked higher intake of fat saturated with reduced risk of cardiovascular disease was a bit of a shock to mí.Mientras finding is in the table of results of the paper, I can't find any mention of it in other authors lugares.Los make this comment, however: "assuming that the inverse association between SFA [saturated fatty acid] and stroke mortality is causative, however, be inappropriate to recommend an increase in the consumption of products containing the SFA to all Japanese people because it can increase the levels of the population of total cholesterol and the risk of IHD [coronary heart disease]."
The authors have right to express any opinion they like, but this is simply not compatible with their own data. According to its conclusions, if the Japanese were increasing their consumption of saturated fats, deaths from heart disease will remain the same, stroke deaths would go down, and would be so deaths due to cardiovascular disease in general.
