This simple diet exchange could help you live longer

A study with over 220,000 people who examined the consumption of butter and vegetable oils has come to a conclusion that shows how much better for them is. The switch could be one of the simplest ways to extend your life.

Crispy scaly cake crusts. Rich velvety sauces. The perfect addition to a tough roasted bagel. In the world of culinary delights, it is difficult to argue against butter. In the world of health studies, however, the streamable source of fat and taste does not receive such high grades.

While many of us already know that butter is not exactly a health feed, a new study by Harvard researchers, with and Mass General Brigham, has how consumption affects our durability and how vegetable oils do exactly the opposite.

The research team examined data from 221,054 participants in three long -term health studies: the nursing care study; The nursing study II and the Follow-up study of health professions. In each of these studies, medical specialists were asked to answer questions about their eating habits every four years.

For the new study, the researchers examined data from these reports for 30 years. They also examined participants who died during this time.

The researchers came to the conclusion that people who ate the most butter had a 15% higher risk of death than those who at least ate. Conversely, they found that those who had the most vegetable olives consumed olive, rapeseed and especially soybean one of 16% lower risk than those who at least ate.

In addition, the team found that every increase in oils on a plant-based basis per 10 grams per day came to a reduction in death risk due to cancer and a 6% reduced risk of death due to cardiovascular diseases. On the other hand, the researchers observed a 12% increased risk of cancer mortality for 10 grams per day. The butter intake was derived from all sources, including use as distribution, roast and consumption of baked goods and other foods.

Simple exchange

The researchers then carried out a substitution analysis in which it was modeled how the exchange of butter could affect vegetable oils in a daily diet. They came to the conclusion that the replacement of only 10 grams of butter per day (about ¾ tablespoons) would reduce the death of cancer and the overall mortality rate by 17%due to the same amount of vegetable oils.

The main difference between the two types of fat is that vegetable oils contain a larger amount of unsaturated fatty acids than butter, which is rich in saturated fatty acids. As you may know, saturated fats were associated with an increase in heart disease and a stroke due to the increased content of harmful LDL cholesterol in the blood.

And although this has been well established for some time, the researchers say that there have been no major study over a long period of time that dealt specifically on the sources of the two fat types and the comparison of head-to-head comparison. However, their work supports the results of another massive study that was carried out last year, which also came to the conclusion of how much better oils are on a plant -based health than butter.

“What is surprising is the extent of the association that we have found-we have seen a 17% lower risk of death when we modeled the exchange butter with herbal oils in the daily diet,” said Yu Zhang, senior author of the study. “This is a fairly enormous impact on health.”

“People may want to take into account that a simple diet exchange, the butter can lead to significant long-term health advantages with soybean or olive oil,” added the corresponding author Daniel Wang, MD, SCD. “From the perspective of public health, this is a considerable number of deaths from cancer or other chronic diseases that could be prevented.”

The study was published in the journal Jama constraint medicine.
