A new study has discovered that eating more butter is linked to greater mortality
How many times do we use (still) butter to give more flavor to our dishes? Many consider it an irreplaceable ingredient, but science has something to complain about.
According to a study by Mass General Brigham, of the Harvard that Chan School of Public Health, of the Broad Institute of the Massachusetts Institute of Technology and Harvard, published in Jama Internal Medicine, in fact, Replacing butter with vegetable oils could reduce the risk of mortality.
A greater consumption of vegetable oils and minor butter could in fact encourage better health, with a reduction in total mortality of 17%. That’s why.
The butter? It is not so healthy
In recent years, diets rich in animal fat have become a real trend, with the undisputed protagonist butter. At the same time, vegetable oil has often been labeled as “less healthy”. But research tells another story.
The research has rather shown that the usual consumption of butter is linked to an increased risk of mortality of the 15%. On the contrary, those who prefer vegetable oils such as soy or olive oils have a 16% less risk of total mortality.
The study
The study examined the eating habits of 221,054 people through a questionnaire completed every four yearscollecting information on the quantities of butter and plant oils consumed. The total consumption of butter included several sources, including butter mixed with margarine, spreadable butter used on bread and other foods, as well as the one used for cooking and domestic fry. The intake of vegetable oils, on the other hand, has been estimated on the basis of their use for frying, browning, baking in the oven and seasoning salads.
Scholars also monitored the deceased participants and analyzed the causes of death. Through a statistical analysis, they compared mortality rates in relation to the different levels of consumption of butter and vegetable oils. The results highlighted that those who assumed more butter had a higher risk of death of the 15% compared to those who consumed Menor, while those who consumed greater quantities of vegetable oils showed a risk of lower death of the 16% compared to those who made it a more limited use.
In addition, the experts conducted a replacement analysis to evaluate the effects of a food change, simulating the impact on the health of the replacement of butter with vegetable oils. The results suggest that Replace 10 grams of butter per day (less than a spoon) with an equivalent quantity of calories from vegetable oils could reduce the risk of death from cancer and overall mortality of 17%.
However, the study presents some limitations, including the fact that the participants were mainly health workers, which may not make the results completely representative of the general population of the United States. For this reason, researchers intend to extend the analysis to more diversified groups of people and deepen the biological mechanisms through which the variations in the diet influence health.
How much butter should we reduce?
According to scholars, there is no need to upset your diet: it would be enough Replace 10 grams of butter per day With a vegetable oil to obtain significant benefits.
We have observed a reduction in mortality risk of 16%. An important fact for public health, explained Dr. Yu Zhang, co -author of the study.
Among other things, the oil is extremely versatile: it can be used to fry, brown, bake in the oven or simply season. Ready to make the change?
