Are sugary drink interventions cutting consumption?

I have written repeatedly about the ill effects of soft drinks, both sugary and diet, on our bodies. You can check out my Page – What’s wrong with soft drinks? for chapter and verse. So this item in Medical News Today citing efforts to curb sugary drink consumption caught my eye.

An evaluation of efforts designed to reduce how many sugary drinks we consume shows some success in changing younger people’s habits but warns they cannot be the only way to cut consumption.


Nutritionists at the University of Leeds have carried out the first comprehensive review of interventions to reduce sugary drinks consumption. The team analyzed 40 studies with 16,500 participants across three age groups: children, teenagers and adults.

Their study, published in the Obesity Reviews journal, found that children participating in these programs reduced their sugary drink intake by around 30%, removing nearly 2.5 teaspoons of sugar from a child’s average intake of 16 teaspoons per day.

Interventions aimed at teenagers saw sugary drink consumption reduced by nearly 10%. However, there was almost no measurable change in adults participating in these programs.

The evaluation highlighted some of the successful behavioral change techniques used, but warned that to achieve significant change in sugary drink consumption additional measures are needed.

First author, Elisa Vargas-Garcia from the School of Food Science and Nutrition, said: “On average sugar intake is two to three times higher than recommended across all age groups. We evaluated these programs to see if they were causing real changes in behavior.

“School is a common place to target obesity-related behavior. However, in the programs aimed at younger populations we found that the interventions that took place in the home were actually more effective.”

Lead author Professor Janet Cade, Professor of Nutritional Epidemiology and Public Health at Leeds, said: “But while the children and teenage programs can claim some success, the lack of effectiveness in interventions for adults is worrying. Interventions alone cannot be relied upon to affect sugary drink behaviors.

“Scientists, public health officials and policy makers need to work together to establish the best courses of action, from increasing the availability of water in and around schools to introducing the levy on sugary drinks companies.”

The only intervention component associated with significant results was when there was a role model to demonstrate ‘good’ behavior towards sugary drinks. In these cases program participants are able to model someone they like or admire, such as parents, causing a change in behavior.

The programs aimed at children and teenagers typically incorporated a number of different components including group-led or class-based sessions that taught about the negative health consequences of drinking too many sugary drinks and targeting unhealthy diet behaviors and promoting water as a drink alternative.

Some of the programs included parental support and worked to change the environment by adding water fountains and filters at schools.

The programs aimed at adults also included nutritional advice sessions to help better understand food labels and how to choose healthier drinks. Several of the adult programs including setting and monitoring personal goals such as making pledges to drink fewer fizzy drinks.

Co-author Dr Charlotte Evans, also from the School of Food Science and Nutrition at Leeds said “It’s estimated that children and adults get about a quarter of their sugar from sugary drinks and these drinks are linked with health risks such as type 2 diabetes, obesity and tooth decay.

“This systematic review is one of many actions needed to plan and implement the best methods to change behaviors and attitudes towards sugary drinks. We also need action to improve the wider environment by making sugary drinks more expensive, less available and less desirable through taxation, reformulation and reduced marketing.”

There are currently a number of public health initiatives to reduce sugary drink consumption. Some of these include campaigns to increase public awareness about the sugar content and the consequences of heavy consumption as well as restricting the availability of sugary drinks and promoting water as an alternative.

The government is also planning on introducing a levy on companies producing sugary drinks starting in April 2018 where drinks with more than 5g of sugars per liter will be taxed. This is encouraging companies to reformulate their drinks so they contain less than 5% sugar.

  1. 5g per liter?! The only thing they won’t be taxing is water. Big shock there. How did that excessive taxation work with cigarettes?

    Look, I simply hate government getting involved with being a nanny to the American people. Besides, that’s a State issue anyway, according to the Constitution.

    • Thanks for your comment, Jim. This isn’t the American people. They’re across the pond. But, I agree with your sentiments on the government being a nanny. How about prohibition? All it did was capitalize criminals. I did like the fact that parents and role models did seem to have a positive influence.

  2. Prohibition was awesome! Talk about unintended consequences! I missed the European angle. In that case, good for them!
