New research. Consumption of smaller amounts of this product can improve health, protect against heart disease and cancer

Butter can be delicious, but a new large study shows that the smaller you eat it, the longer you live. According to the report published in Jama Internal Medicine and presented on the EPI/Lifestyle Scientific Sessions of the American Cardiological Association, the use of more vegetable oils and less butter was associated with a decrease in the risk of premature death by 17% and less than a 17% risk.

Researchers from the Brigam and Women’s Hospital Hospital have analyzed more than 200,000 people in Boston, who have been watching for over three decades. Researchers found that the participants who reported that they consumed the highest daily butter had 15% more likely to die prematurely, while people who consumed a large amount of vegetable oils, especially soybean, rapeseed and olive, had 16% less likely to die.

“The message of this study is as follows: less butter and more vegetable oil can contribute to improving health,” said the leading author of the study Yu Zhang, graduate student of Harvard University T.H. School of Public Health Chan and a researcher at the Brigamian Women’s Hospital. “We do not say that people have to completely give up the oil,” Zhang said. “But we assume that a slight reduction in daily consumption and increase in vegetable oil can lead to significant long -term health benefits.”

Zhang was unable to say exactly how much oil could be consumed but “Less would be better. ” The new study discussed the data of 221 054 adults who participated in the health studies of the nurses, the study of the health of nurses II and the study of healthcare professionals. At the beginning, the average age of people in the health studies of the nurses and the subsequent examination of medical workers was 56 years, and 36 – in the health care study of nurses II.

Every four years, the participants filled in the feed rate of food, which included more than 130 points. They were asked how often they consumed each product on average over the past year. Participants had nine possible answers from “never or rarely once a month” to “more than six or more times a day”. They were also asked what types of fats and oils they consumed and what brands or types of oils they used.

For 33 years of observation 50 932 participants died, 12 241 due to cancer and 11 240 due to heart disease. After taking into account the potentially displacing lifestyle factors, such as body mass index, physical activity, smoking and alcohol use, as well as family history of diabetes, cancer and cardiovascular disease, researchers found that people who consumed the highest daily amount of butter (13–14 grams or about three small pieces), were 15% more likely to die compared to those who consumed the least number (0.1–0.2). grams or almost none). This is unlike 16% lower risk of death in those who consumed the highest amount of vegetable oils (about 25 grams, about five teaspoons a day) compared to those who consumed the smallest amount (about 3 grams a day or 1 teaspoon).

Using the statistical model, researchers estimated the difference in mortality levels when vegetable oils were replaced by about a teaspoon of butter daily and found a decrease in the risk of death by 17%. When scientists studied the causes of death, they found that every additional 10 grams (About 2 teaspoons) per day of vegetable oil were associated with a decrease in the risk of death from cancer by 11% and the risk of death from cardiovascular disease by 6%.

The new study is consistent with the current recommendations of the American Cardiological Association to replace animal and milk fat with polyunsaturated and unsaturated fats.
