The use of certain vegetable oils instead of butter can help people live longer, live healthier, according to one New study.
The study, published in Jama Internal Medicine on Thursday, is building on one big body by research in particular show the health benefits of olive oil Recent studies who have the complicated conventional wisdom about the tires of butter with heart conditions and the general death risk. By following food and death data from 221,054 adults for more than 30 years, the authors of the study say that they have gained useful insights into the long-term consequences of the specific types of fats we eat.
“The collection meals are very simple: a higher intake of butter is associated with a higher risk of early death and a higher intake of vegetable oil is associated with a lower risk of premature death,” said Daniel Wang, the accompanying author of the study and a university teacher in Brigham and Women’s Hospital. People who ate the most butter had a 15% higher death risk compared to people who ate the least butter, while people who ate the most vegetable oils had a 16% lower death risk.
The study also showed that exchanging only 10 grams (less than a tablespoon) of butter per day with an equivalent amount of vegetable oils could generally reduce the risk of death by 17%, as well as reducing the risk of death due to cancer by 17%. ‘If you can replace [butter]You can enjoy quite a bit of health benefit in terms of large chronic diseases, “Wang said.
The findings of the Jama study about the benefits of Canola and soybean oil challenges thinking in those who try to avoid so-called seed oil, including Canola and Soy, because of concern about their possible ties with chronic diseases. A number of people involved in the Make America Remory Reference, including health secretary Robert F. Kennedy Jr., have suggested that it is better to shun vegetable oils with industrial processes and recommended butter, along with alternatives such as coconut oil and beef as substitutes.
But the consensus among nutrition experts, strengthened by this new study, is that plant oils are generally preferable to animal fats.
Like most food studies, this was an observational study instead of randomized. The participants of the study filled in surveys every four years about what they ate and how much. Most of them were white health workers, who notice the authors of the study as a limitation that can make the results less generalized.
Wang acknowledged that participants may have had a hard time remembering with full accuracy what they ate for a period of four years, but said the authors discovered that errors were non-differential, which means that people would make such mistakes just as likely, regardless of their health insurance. Moreover, he said via e -mail: “This type of error tends to weaken associations, which means that the results reported in the paper are in fact conservative estimates of the relationship between intake and mortality of vegetable oil, and very unlikely that they are false positive findings.”
Even when they checked for the possibility that people who ate more butter had diets of lesser quality than people who ate more vegetable oils, the study still found a connection between higher butter consumption and a greater death risk. Under vegetable oils, olive oil, canola oil and soybean oil were specifically associated with a lower risk of death.
“This new research contributes to a large number of science on the health benefits of these vegetable oils, whose positive effects on cholesterol levels, blood glucose and cardiovascular diseases have been demonstrated in numerous large observation studies and dozens of randomized studies,” said Dariush Mozaffture in Tuzafferts in Tuzafferts in Tuzafftute in Bijzaffture in Tuzaffture in Tuzafftute in Bijzaffture, University in Tufts. He noticed that the study found no evidence that corn and safflower oil, which were less popular choices in participants, are useful or harmful to health.
Mozaffarian was co-author of a buzzy 2016 meta-analysis This discovered that butter was largely a neutral food in terms of its long-term impact on death, cardiovascular disease and cancer. He asked the conclusions of the new study about butter and noted that among people in the study who generally had healthier diets, butter had no connection with a higher death risk. For him, “butter has minimal effects if you otherwise eat a healthy diet.”
“In general, butter is probably quite neutral for health – worse than vegetable oils, fruit or nuts, but better than the white bread it is spread about,” said Mozaffarian.
The new study and the long -term debate on fats have implications for equity, said the authors of one commentary Published next to the study.
“Analyzes excluding olive oil indicated a consistent inverted association between replacing vegetable oils and reduced death risk,” write authors Yong-Moon Mark Park of the University of Arkansas’ School of Public Health and Yikyung Park of Washington University School of Medicine. “This suggests that more affordable options, such as Canola and Soybean oil, can serve as accessible alternatives to olive oil, which is usually more expensive.”
