This is the conclusion reached by two researchers from the University of Glasgow (Scotland), and whose study has been published in The Lancet Diabetes & Endocrinology journal.
The high sugar content is responsible for the fact that packaged fruit juices have been compared to soft drinks or carbonated drinks, therefore, it is recommended to limit their intake as with other unhealthy foods.
To reach this conclusion, the researchers conducted an experiment in which participants drank half a liter of grape juice every day for three months. At the end of this time, the participants began to have an increasing resistance to insulin and a larger waist .
The researchers ask the companies that distribute fruit juices to inform consumers more fully of the components of the same and that it is recommended not to take more than 150 ml per day of packaged juice .
"There is a misperception that packaged fruit juices and smoothies are low-sugar alternatives to sugar-sweetened beverages," says Jason Gill, professor at the Institute of Cardiovascular and Medical Sciences at Glasglow University.
A glass of fruit juice contains substantially more sugar than a piece of fruit and, one of the positive qualities that we find in fresh fruit, such as fiber, is not found in packaged juices , or it exists in minimal quantities.
