Scientists have linked regular soda consumption to the risk of liver cancer
Regular consumption of beverages with added sugar is associated with an increased risk of two main forms of liver cancer — hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICH). This conclusion is contained in a large-scale study led by Cody Watling from the US National Institute of Oncology. The data covers more than 1.5 million adult participants from 11 long-term cohorts. This was reported on June 10 in the journal Medical Xpress.
The researchers analyzed nutrition data from meal frequency questionnaires and tracked cancer outcomes through cancer registries and medical examinations. The average follow-up period was almost 18 years. The analysis focused on both drinks with added sugar (carbonated, juices with sugar) and those containing artificial sweeteners.
Higher consumption of sugary drinks is statistically associated with an increased risk of HCC and HCV, two different malignancies that occur in liver cells and bile ducts, respectively. Drinks with artificial sweeteners, in contrast, showed no association with any of the subtypes of cancer.
The authors emphasize the observational nature of the work: the study records a statistical relationship, but does not establish a causal relationship between the consumption of sugary drinks and cancer. At the same time, the results add to the body of data on the long—term risks of sugar-containing beverages previously associated with obesity, type 2 diabetes, and non-alcoholic fatty liver disease, recognized risk factors for HCC.
Marina Ivanova, a nutritionist at the Fitomarket marketplace, told on Tuesday, May 5, what can cause absent-mindedness, a feeling of fog in the head, memory impairment and concentration. The specialist explained that memory can deteriorate due to constant stress, as it increases cortisol levels, which negatively affects a person's ability to remember and learn.
