A US study of a thousand participants, of roughly equal male and female, underwent CT scans to look at body fat changes over a six-year period. The results found that the more sugary drinks were consumed, the higher the amount of this visceral fat was found in the abdomen. It is currently unknown what the biological mechanisms behind this are, but the association appears quite strong.
Visceral fat around the abdomen increases the risk of coronary artery disease, diabetes, and some cancers. Sugar can be found in many types of drinks, even those that appear to be healthy.
What about diet drinks, sweetened with artificial sweeteners? Well, some studies show that the sweeteners in drinks could still lead to obesity and other health issues. It’s possible that these compounds interfere with the natural bacteria in our guts, typically those that protect us from obesity and diabetes. These chemicals are many times sweeter than sugar, and its possible that the very sweet taste might drive our behaviour to seek sweet foods elsewhere too. So even artificial sweeteners may not be helping the cause.
