Sugar-sweetened drinks and cancer risk

Avoid sugar sweetened drinksThere’s no strong evidence to link sugar and cancer directly.

However, if you regularly drink sugary drinks, or drink them in large portions you are more likely to be consuming more calories than you burn.

It can be easy to drink too many sugary drinks as they aren’t very filling, despite being quite high in calories. This can lead to weight gain, being overweight and obese, which in turn can cause many cancers.
