The sugar content in fruit drinks is underestimated, experts warn. Their consumption can lead to higher than the recommended daily calorie intake, according to a study by the University of Glasgow.
Researchers tracked the eating habits of 2,000 people in the UK and found that there was a lack of awareness of the sugar content of carbonated beverages, as well as shakes and fruit juices.
A survey of volunteers shows that the consumption of beverages consumes up to 450 calories per day, which is 1/4 of the daily caloric intake of women and 1/5 of that of men.
For the purposes of the study, participants should indicate, at their discretion, what the sugar content of several popular beverages is. It turns out that they underestimate it with between 2-4 teaspoons in natural apple and orange juice, caffeinated energy drinks and various shakes.
Participants also underestimated the sugar content in pomegranate juice, with almost 18 teaspoons.
The British Association of Soft Drinks Producers states that the level of sugar in beverages is not hidden and is clearly indicated on the product label, including the calorie content.
Excessive consumption of soft drinks leads to obesity and is a major risk factor for diseases such as diabetes, high blood pressure, heart disease and stroke, scientists warn.
Too high a sugar content in soft drinks can significantly contribute to the development of obesity, says lead researcher Prof. Naveed Satar. Some varieties of drinks, such as natural fruit juices and shakes, which are perceived as "healthy" options, can also be high in sugar, the expert added.
People who have weight problems are advised to reduce the consumption of such juices and replace it with more water or diet drinks, scientists advise.
