Fat fish, nuts and avocados – indicated to be sources of ‘healthy’ fats – cannot be as good for us as previously assumed, scientists have claimed.
The most important culprit, according to Australian researchers, is fats in these foods known as omega-3-Die studies have previously presented to protect the health of the heart.
However, new evidence suggests that omega-3 is linked to inflammation in the body, increasing the risk of obesity, type 2 diabetes And even a heart attack.
The findings come from a large study with 2,800 participants in the Landmark Avon Longitudinal Study of Parents and Children (Alspac), also known as children of the 90s of the most detailed long-term health studies ever.
Since 1991, researchers have followed the health of more than 14,000 families in the Avon area, when the mothers were first recruited during pregnancy. The last investigation looked at data that were collected when the children turned 24.
After taking into account lifestyle factors such as smoking, scientists discovered that diets rich in Omega-6 were associated with higher levels of glyca-a blood biomarker in connection with chronic inflammation, cancer and heart problems.
Omega-6, found in vegetable and sperm oil, has increasingly been associated with poor health of the heart in recent years.
Surprisingly, however, the researchers also found elevated glyca in people who consumed food rich in omega-3 fats, which are usually considered ‘heart healthy’.
Unsaturated fats, such as those found in oily fish, nuts, seeds, avocados and olive oil, have long been defended as the answer to the defense of heart -related death and keeping up with bad cholesterol remotely
NHS data show an increase in the number of younger adults who have suffered from heart attacks over the past decade
Although some warning signals are easy to recognize – such as serious chest pain – others are more vagient and difficult to locate
Professor Thomas Holland, from the Rush Institute for Healthy Aging, Chicago, which was not involved in the research, said Medical news today The results were ‘unexpected’.
He added: ‘Omega-3s can be found in dark fat fish, such as salmon and sardines, and in vegetable foods such as linseed, chia seeds and walnuts.
‘Most people consider them calming for the immune system. But in this study, higher Omega-3 levels were linked to more inflammation, no less. ‘
The main author of the study, Professor Daisy Crick, an expert in the Molecular Science of Queensland University, said: “Our findings suggest that it is not as easy as” Omega-3 is anti-inflammatory and omega-6 is pro-inflammatory “.”
She added that simply increasing the Omega-3 intake is not enough to reduce inflammation or protect it against heart disease.
“Improving the balance between the two fats can be a better method for people who want to reduce inflammation in their bodies,” she said.
The study, published in the International Journal of Epidemiology, calls for further research to better understand how different fatty acids influence health in the long term.
Seed oil – such as sunflower, soy and rapeseed – contain many polyunsaturated fats and have long been promoted as a ‘heart healthy’ alternative to saturated fats such as butter and lard.

But Professor Holland warned that the rising consumption of seed oil obesity, heart disease, type 2 diabetes and even car -immune disorders could feed.
It is thought that about 6.3 million people have raised cholesterol in the UK, which can cause untreated heart attacks and strokes, and seed oil can contribute to this, Suggered Prof. Holland.
It was the alarming figures last year that it revealed that premature deaths had reached their highest level in more than a decade due to heart attacks and strokes.
MailOnline has previously emphasized how the number of younger than 40, in England that is treated by the NHS for heart attacks, is treated.
Cases of heart attacks, heart failure and strokes among the 75s have fallen since the 1960s.
It is believed that this is due to the fall of smoking percentages, advanced surgical techniques and breakthroughs such as stents and statins.
But now the rising obesity rates and the catalog of associated health problems such as high blood pressure and diabetes are considered one of the most important contributing factors.
