Uterine cancer: soft drinks increase the risk

For many health experts, soft drinks are one of the worst inventions of modern industrial food. Since becoming ubiquitous in the daily diet, these beverages have been the cause of several serious health issues, with increased risk of uterine cancer being the latest in a long list.

Advertising campaigns always present soft drinks in a positive light, as cool products, consumed by dynamic people who enjoy life to the full. No offense to the designers of these advertisements, the reality could not be more different: most people who regularly consume soft drinks are far from being in good shape, because they are rather overweight, with a high risk of prematurely develop type 2 diabetes.

The salty note of sugary drinks

Mexico is probably the best illustration of how quickly these drinks can deteriorate the health of a population: from 1989 to 2004, the consumption of soft drinks by Mexicans skyrocketed, reaching an average of 146 liters per person per year. , with a parallel increase in the incidence of obesity from 10% to 70% and that of diabetes from 2% to 15%.

These negative impacts are a direct consequence of the astronomical amounts of sugar present in these drinks, which promote overweight, as well as excessive variations in insulin secretion which end up compromising the functioning of the pancreas and causing the development of diabetes.

For many leading health specialists, soft drinks are one of the worst inventions of modern industrial food, a real poison that poses a serious threat to the healthy life expectancy of the population, such as the reported the prestigious journal Nature.

Pro-obesity, pro-diabetes and pro-cancer drink

A recent study indicates that the harmful effects of soft drinks on the metabolism could also promote the development of certain cancers. In 1986, American researchers recruited some 23,039 women with an average age of 62 and followed them until 2010, during which time they analyzed their eating habits and the incidence of cancer.

They observed that women who consumed the highest amounts of sugar had a higher risk of developing cancer of the endometrium (the lining of the uterus), with this impact being particularly pronounced in those who drank the larger amounts of soft drinks (78% increased risk).

Increased body weight certainly plays a role in this effect, as most uterine cancers are estrogen dependent and these hormones are increased by excess body fat. Obesity also increases the amounts of certain pro-cancer growth factors (IGF-1) which bind directly to cells in the uterine lining and stimulate their proliferation, which may contribute to the progression of cancer.

People who consume a lot of soft drinks often have an unhealthier lifestyle, and it is possible that additional factors contribute to the increased incidence of cancer observed in the study. Be that as it may, the metabolic disturbances caused by soft drinks must be considered as an established risk factor for certain cancers, another illustration of the many damages that these drinks inflict on our health.
