The obesity risks of sugary drinks are well-known and still growing around the world to increase year on year.

Now, a worrying new study has been published which suggests these fizzy drinks and cancer.

The study, outlined in the British Medical Journal (BMJ), says the research has been shown to be significantly lower than the risk of overall cancer.

The study involved 101,257 participants (21% men; 79% women) all of whom were healthy and aged over 18. The average participant age was 42 years old.

To begin with, the participants completed questionnaires that were designed to measure their average intake of 3,300 different kinds of food and beverages.

They were then followed by the research team for their years (from 2009 to 2018) who measured their daily intake of sugary drinks and added sugar. When health care was first reported to the study, it was validated by medical records and health insurance databases.

Over the course of the study, 2,193 first cases of cancer were diagnosed and validated (693 breast cancers, 291 prostate cancers, and 166 colorectal cancers).

The average age at which cancer diagnosis was 59 years.

The research team concluded that an increase in breast cancer was associated with an increased risk of breast cancer.

Part of that may be the inseparable weight that comes with drinking lots and lots of sugar.

'The association between sugary drinks and the risk of cancer may be explained by their effect on overweight and obesity onset, since in turn, pharynx, larynx, oesophageal (adenocarcinoma), stomach (cardia ), pancreatic, gallbladder, liver, colorectal, breast (postmenopausal), ovarian, endometrial, prostate (advanced), and kidney cancers, 'explains the BMJ.

It goes on to say that this study was more about observing the link, rather than explaining why it's there.

'This is an observational study, so can not establish cause, and the authors say they can not rule out some misclassification of beverages or guarantee detection of every new cancer case,' the authors write.

Nevertheless, the study was broad and they were able to adjust for a wide range of potentially influential factors. What's more, the results were largely unchanged after further testing, suggesting that the findings withstand scrutiny.

To validate the results further, the authors say that other broad studies of this kind need to be carried out. In the meantime, they say that for the sake of our collective health, it might not be a bad idea to tax sugary drinks even further.

They conclude: "These data support the relevance of existing nutritional recommendations, including 100% fruit juice, such as taxes and marketing restrictions targeting sugary drinks, which may be potentially contributing to the reduction of cancer. impact.'
