Drinking just a third of a can of soft drink a day increases the risk of developing cancer* by up to 22 per cent, according to new research.
Drinking fruit juice was also shown to increase the risk of developing cancer.
Public health expert Professor Lennert Veerman from Griffith University, Qld, said the research, published in the British Medical Journal is the “first to convincingly* link these drinks directly to cancer risk”.
In the study, French researchers examined 3300 food and drinks over a maximum of nine years in 101,257 healthy French adults
They found that a 100ml increased intake of sugary drinks was associated with an 18 per cent increased risk of overall cancer and a 22 per cent increase in the risk of breast cancer.
The team of French researchers believe that sugar in the drinks causes our bodies to store more fat around organs such as the liver* and pancreas*, and this has been linked to a higher risk of cancer.
“Much of the cancer risk is likely to arise* via obesity*. This points once again to the need to reduce the consumption of sugary drinks for health,” Prof Veerman said.
“Sugar should be treated much like alcohol and tobacco*. While an information campaign would be helpful, it is unlikely to have a significant* impact* on its own.
“Taxation* and advertising restrictions are probably also needed.
“Modelling* studies have shown that both can lead to large improvements in health.
“They are likely to be good for the economy too — a healthy population is a more productive* population.”
The study found that average daily consumption* of sugary drinks was greater in men than in women.
Men drank 90.3ml and women 74.6ml. During follow-up, 2193 first cases of cancer were diagnosed* and confirmed.
Because this is what is called an observational study (which means the researchers just observed or watched what people did and what happened to them, rather than trying to change anything) the researchers can’t say what caused the cancers, just that they occurred at a higher rate in people who drank sugary drinks.
However, the study involved a large number of people and the researchers got very similar results when they did later testing, which means that the results are likely to be reliable.
“The authors conclude that the sugary drinks widely consumed as part of our so-called ‘western’ diet represent an opportunity for cancer prevention,” Professor Margaret Morris from the School of Medical Sciences and Head of the Environmental Determinants of Obesity Group at the University of New South Wales said.
The researchers did not find cancer links to drinking artificially sweetened diet drinks.

LISTEN TO THIS STORY
1. Sugar Tax
The three main ways to try and convince people to cut out sugary drinks from their diet include an information campaign, taxation and advertising restrictions.
Draw a table on your page with three columns. List the three strategies in the first column and. Label the second column pros (positives) and the third column cons (negatives). Complete the table for all three of these strategies.
The strategies are:
INFORMATION CAMPAIGN: informing people of the increased cancer risk, risk of obesity and other negative effects of drinking these sugary drinks.
TAXATION: putting a tax on sugary drinks so they cost more to buy
ADVERTISING RESTRICTIONS: government to restrict the amount and times that companies can advertise these sugary drink products so they are not so widely seen
Give your overall recommendation about which strategy you think would work best.
