Studies show that even a small portion of fried food can increase the risk of heart disease – Boston news, weather, sports

(CNN) —Eating fried foods may increase the risk of major heart disease and stroke, according to a new analysis of existing studies.

Compared to those who ate the most fried foods per week, they had a 28% higher risk of major cardiovascular events, a 22% higher risk of coronary heart disease, and a 37% higher risk of heart failure. According to a study published in the journal Heart on Monday..

Each weekly addition of 114 grams or 4 ounces (1/2 cup) of fried food increased the risk of heart attack and stroke by 3%, heart disease by 2%, and heart failure by 12%. I know in. A Medium McDonald’s French Fries ServingFor example, 117 grams.

No association was found for cardiovascular disease or death from any cause, but researchers said this could be a relatively small number of reasons included in some studies.

Fried food and trans fat

When frying food, some of the fat is absorbed from the oil, which can increase calories. In addition, commercial fried foods and processed foods often contain trans fats created by an industrialized process of adding hydrogen to liquid vegetable oils to make them harder (think semi-soft margarines and shortenings). ).

The food industry loves trans fats. Because they are cheap to manufacture, they last a long time and give foods a great taste and texture.

Besides fried foods, coffee creamers, cakes, pie crusts, frozen pizzas, cookies, crackers, biscuits and dozens of other processed foods contain trans fat.

The U.S. Food and Drug Administration banned trans fat in 2015, but extended the industry period — latest Until June 18, 2019, we stopped producing food products, and by January 1, 2021, we gave companies to make these products work in the market.

However, there are still loopholes. The FDA allows companies to label foods with “0 grams” of trans fat if one serving of the food contains less than 0.5 grams.

Experts say that when people eat such foods multiple times, small amounts can quickly increase. Other conditions such as cardiovascular disease, diabetes, and dementia..

According to the American Heart Association, Trans fats raise your bad cholesterol levels and lower your good cholesterol levels. AHA recommends replacing trans fats in fried and processed foods with monounsaturated or polyunsaturated fats such as olive oil and canola oil.

Association only

Despite the evidence behind the health effects of trans fats, this meta-analysis of studies can only show Relationship between fried food intake and cardiovascular risk.

“The results of this study are consistent with current guidance on limiting fried food intake, but are not considered to provide conclusive evidence of the role of fried food consumption in cardiovascular health,” said University College. Alun Hughes, a professor of cardiovascular physiology and pharmacology at London, in a statement. Hughes was not involved in the study.

This is because most studies of this type responded that the study participants remembered the amount and type of fried food they ate. In addition, high fried food consumption is likely to be associated with overeating, obesity, lack of exercise, and other unhealthy behaviors that can contribute to heart disease, experts say.

“When the relationship is causal, many of these foods are highly processed and often contain both fat and carbohydrates together, ensuring this association in the fat content of the food. It doesn’t necessarily depend on, “said registered nutritionist Duein Meller. Senior Teaching Fellow at Aston Medical College in Birmingham, England.

“Therefore, when considering this type of study, reducing fat intake is a logical part of a healthy diet, but it is also important to look at what foods are being eaten instead. It’s important to take that into account, “Meller said. Not involved in research.
