Drinking natural fruit juice is also linked to increased risk of premature death



Many drinks sweetened with sugar have little or no nutritional value and many calories, and their harmful health effects have been well documented. Now a study connects the consumption of too many sugary drinks, and even 100% natural fruit juices, with a higher risk of premature death.

Specifically, drink too much fruit juice may lead to an increased risk of premature death which varies from 9% to 42%, according to the study, published on Friday in the newspaper JAMA Network Open.

In general, the sugars are in orange juice, although naturally occurring They are much like sugars for soft drinks and other sweetened drinks, the study suggests.

"Sick drinks, whether soft drinks or fruit juices, should be limited", Jean A. Welsh, co-author of the study and assistant professor of the Department of Pediatric Medicine at Emory University in Atlanta, wrote in an email.

Relationship to cardiovascular disease

Seven US cities, including New York and, recently, Philadelphia, have applied Taxes on beverages sweetened with added sugar in an attempt to reduce consumption. These laws often highlight how soft drinks and other sugary drinks contribute to the obesity epidemic in children and high diabetes rates among adults.

The new study defined "sweet drinks" as thirst queners sweetened with sugar, such as fruit-sanded infusions of soda and 100% natural fruit juices that have not added sugar. then, How does fruit juice collect against soft drinks?

Previous research has shown that a high intake of sugars, such as soft drinks and fruit juices, is linked to several risk factors for cardiovascular disease, Welsh explains. Obesity, diabetes and high triglycerides (a type of fat found in the blood) are among the risk factors associated with excessive sugar consumption. "Few studies have been able to see how this consumption can affect the risk of mortality," he said.

To solve this problem, she and her colleagues redirected data from the study "Reasons for geographical and racial differences in stroke", which aims to understand why more African Americans die of stroke than other competitions and why people in the southeast have more strokes than those in other areas of the United States.

From this multi-ethnic study, Welsh and his co-authors analyzed data on 13,440 adults over 45, nearly 60 percent of men and nearly 71 percent of them overweight or overweight.

People who consumed 10% or more of their daily calories as sweet sweets had a 44% higher risk of dying from cardiovascular disease and a 14% higher risk of premature death from any cause compared to people who consumed less than 5% of their daily calories as sweet drinks, the study showed.

Each additional portion of 350 ml of fruit juice per day was associated with a 24% higher risk of death for some reason, and each additional serving of 350 ml of sugary drinks a day was associated with an 11% higher risk. A similar relationship between sugary drinks and death due to coronary artery disease could not be found.

"When we observe our results of sweet drinks and juices independently, we must be clear that the risk presented is relative to today's in the lowest consumers of each," Welsh explained.

I was not surprised at the results. She and her co-authors said "a series of possible biological mechanisms" explains the high risk of death. For example, research suggests that sweet drinks increase insulin resistance, which is known to increase the risk of cardiovascular disease, while fruit consumption can stimulate hormones that promote weight gain around the waist, another risk factor for cardiovascular disease.

Recommended amounts of fruit juice

This is one of the first studies to investigate the relationship between sweet drinks, including 100% fruit juices and premature death, Marta Guasch-Ferré, a researcher at the Harvard Nutrition Department, wrote the School of Public Health T.H. Chan and Dr. Frank B. Hu, professor of medicine at Harvard Medical School, in an editorial published together with the new study.

However, the study is limited in what it can tell us, noted Guasch-Ferré and Hu, who did not participate in the research. Since there were so few deaths associated with coronary artery disease, the analysis here is considered weak; more time and a larger number of participants would probably give a stronger signal in some way. Moreover, The consumption of sugary drinks from each participant was recorded only at the beginning of the study, entirely based on self-information, which is not considered reliable.

"Although fruit juices may not be as harmful as drinks sweetened with sugar, Consumption should be moderate in children and adults, especially in people who want to control their body weight, "wrote Guasch-Ferré and Hu.

recommendations For children between 1 and 6 years, one should limit the consumption of fruit juice to 170 ml per dayWhile children 7 and older, adolescents and adults should limit fruit juices to 230 ml per day, according to the American Academy of Pediatrics and Dietary Guidelines for Americans.

"More research is needed to investigate the health risks and potential benefits of specific fruit juices," said Guasch-Ferré and Hu.

Welsh said we should consider both fruit juices and sweet drinks when we consider how much sugar we consume each day. Between the two he tipped the waves to juice: "Given its vitamin and mineral content, fruit juice in small amounts can have a beneficial effect not seen with soft drinks and other sweet drinks".
