Many sugary drinks with sugar have little or no nutritional value and many calories, and their harmful effects on health have been well documented. Now, research links the consumption of too many sweet drinks, and Even 100% natural fruit juices, with a higher risk of premature death.
Specifically, drink an excessive amount of fruit juice May lead to an increased risk of premature death, ranging from 9% to 42%, According to the study, published Friday in the magazine The JAMA network is open.
In general, sugars found in orange juice, although they occur naturally, They are very similar to sugars added to soft drinks and other sweetened beverages, Suggests the study.
"Candied drinks, whether they are soft drinks or fruit juices, should be limited", Walsh, co-author of the study and professor of pediatric medicine at Emory University in Atlanta, wrote in an e-mail.
Contact with cardiovascular disease
Seven cities in the US, including New York, and more recently, Philadelphia, have implemented Taxes on sugary drinks plus sugar In an effort to reduce consumption. These laws often highlight how sodas and other sweet drinks contribute to the obesity epidemic among children and the high rates of diabetes among adults.

The new study defined a "sweet drink" as sugary sugars, such as fruit soft drinks infusions and 100 percent natural fruit juices that do not add sugar. so, How does fruit juice accumulate against soda?
Previous studies have shown that high consumption of sugars, such as soft drinks and fruit juices, is associated with several risk factors for cardiovascular disease, Walsh explains. Obesity, diabetes, and high triglycerides are among the risk factors associated with excessive sugar intake. "Few studies have been able to see how this should affect the risk of mortality," he said.
To address this problem, she and her colleagues drew data from the "Causes of Geographical and Racial Differences in Stroke" study, which seeks to understand why More African Americans die of stroke than other races And why people in the Southeast have more strokes than those in other areas of the United States.
From this multicultural study, Welsh and his research have provided data for 13,440 adults over 45 years, nearly 60% of men and nearly 71% of them overweight or obese.
People who consumed 10% or more of their daily calories as sugary sugar drinks had a 44% higher risk of dying from coronary heart disease And 14 percent more likely to die prematurely than people who consumed less than 5 percent of their daily calories, such as sweet drinks, according to a new study.
Each additional dose of 350 milliliters of fruit juice per day was associated with a 24% higher risk of death For any reason, and each additional dose of 350 milliliters of sweet drinks per day was associated with a 11% higher risk. No similar association was found between sweets and death due to coronary heart disease.
"When we see the results of independent drinks and juices, we need to be clear that the risk presented is relative to the present in the lowest consumers of each," Walsh explained.

I was not surprised by the findings. According to her, "a series of possible biological mechanisms" explains the high risk of death. For example, studies have shown that sweetened beverages increase insulin resistance, which is known to increase the risk of cardiovascular disease, while fructose may stimulate hormones that promote weight gain around the waist, a risk factor for cardiovascular disease.
Recommended amounts of fruit juice
This is one of the first studies to examine the relationship between sweet drinks, including 100% fruit juices, and premature death, Wrote Martha Gouache-Pre, research scientist at the Harvard Department of Nutrition, School of Public Health. Anne and Dr. Frank Bo, a professor of medicine at the Harvard School of Medicine, published an editorial along 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 study. Because there have been so few deaths associated with coronary heart disease, the operation here is considered weak; More time and a larger number of participants would probably give a stronger signal in any way. also, The consumption of candied drinks of each participant was recorded only at the beginning of the study, based entirely on self-information, which is not considered reliable.
"Although fruit juices can not be as harmful as sugary drinks with sugar, Should be mild 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 of age they limit the intake of fruit juice to 170 ml per day, While children 7 and older, adolescents and adults should limit fruit juice to 230 milliliters per day, according to the American Academy of Pediatrics and dietary guidelines for Americans.
"Further research is needed to examine the health risks and potential benefits of specific fruit juices," said Guasch-Ferré and Hu.
Welsh said we should also consider fruit juices and sweet drinks when we think about the amount of sugar we consume every day. Between the two he dropped the scales for fruit juice: "Considering the vitamin and mineral content, fruit juice in small amounts can have a beneficial effect that does not appear with carbonated beverages and other sweet drinks".
