Consuming fruit juices are just as bad for your health and are likely to lead to an early death like drinking cola or lemonade, suggesting research.
A new study showed an increased risk of dying early from any cause of humans who consumed a lot of sugary drinks.
American scientists first compared 100% fruit juice with sugar-sweet drinks such as cola and lemonade.
They found very similar associations for both fruit juices and sugary drinks with an increased risk of dying early, although they said that more research was needed.
A British expert described the study as important, but said there was no risk of a single 150 ml glass of fruit juice a day.
The new research, published in the Journal of the American Medical Association (JAMA), analyzed data from 13,440 people.
Their intake of sugary drinks and 100% fruit juice was recorded via a questionnaire on how often they consumed the beverages.
During an average follow-up of six years, there were 1,000 deaths from any cause and 168 deaths from coronary heart disease.
Typically, people in the study received 8.4% of their calorie intake each day from sugar-testing beverages and 4% from 100% fruit juice.
People were considered to have a high intake of these drinks if 10% or more of the energy intake originates from these beverages compared to those with low intake (less than 5%).
Taking into account factors such as obesity, people had an 11% increased risk of dying from any cause for each additional 12oz sugar experiment consumed daily and a 24% increased risk for each additional 12oz fruit juice consumed daily.
The researchers, including from Emory University in Atlanta and Cornell University in New York, said: "These results suggest higher consumption of sugary drinks, including fruit juices, is associated with increased mortality.
"The nutritional content of 100% fruit juice and SSB (sugar-sweetened drinks) is very similar.
"While 100% fruit juices contain some vitamins and phytonutrients that are lacking in most SSBs, they are predominantly ingredients in both sugar and water.
"Although sugars in SSBs are added during processing, and sugars in 100% fruit juices occur naturally, the specific sugars they allow the body to treat are essentially the same and the biochemical response when metabolized." is the same."
The authors suggested a few possible causes for the increased risk of dying from sugary drinks.
Obesity is, of course, the most important factor, they said, but when taken into account, research suggests that sugary drinks increase insulin resistance.
Other factors may be that consuming fructose alters blood lipid levels, markers of inflammation and blood pressure, while high glucose consumption has been associated with insulin resistance and diabetes.
Dr. Gunter Kuhnle, Associate Professor of Nutrition and Health at the University of Reading, said: "This is a very important study, especially as fruit juices are often seen as a" healthy "alternative to sugary drinks, although they often contain much more sugar (especially smoothies).
"Fruit juices can provide vitamins and even some fibers, but there are little health benefits besides this: the amount of phytochemical found in juices is too low to have any additional beneficial effect and there is no beneficial health effect from so-called antioxidants.
"If the association has proven to be causal (as we do not yet know), this would have a number of implications: first, it would indicate that it does not matter whether sugary drinks are lemonades or fruit juices.
"This is important as fruit juices and smoothies are not commonly perceived as sugary drinks. Secondly, it suggests that alleged health benefits of fruit juices are not sufficient to counteract their sugar content.
"Fruit juice is a bad substitute for actual fruit consumption, especially as they can be much easier to over-use.
"A 150 ml glass of orange juice is actually made from about two oranges – but it takes much longer to eat two oranges than to drink the juice.
"In the United Kingdom, the general recommendation is that a 150 ml glass of fruit juice can provide one of the five-day but no more.
"This is less than half the amount found in this study to result in a modest increase in mortality, so there is no suggestion from this study that a glass a day is problematic."
