Sodas, energy drinks, and other beverages with added sugar are common parts of many people’s diets. While sugary drinks have been linked to several types of cancer, their connection to stomach cancer has been less clear. Now, a large, long-term study suggests that drinking these beverages regularly may be linked to an increased risk of stomach cancer.
A team of researchers analyzed data from over 112,000 adults enrolled in two major Harvard health studies. Participants were followed for decades, providing detailed information about their eating habits and health. Among them, 278 developed stomach cancer.
The results showed that daily consumers of sugary drinks had two and a half times the risk of being diagnosed with stomach cancer when compared with those who occasionally drank them or less than one per month. The researchers took other stomach cancer risk factors into account, but the association remained. The findings were similar for men and women.
For the study, sugary drinks included regular sodas, lemonades, punches and sports drinks, while artificially sweetened drinks included low-calorie options such as diet sodas. Artificially sweetened drinks did not show the same association. After considering other potential risk factors, researchers found that greater consumption of these were not linked to a higher incidence of stomach cancer.
The risk did not appear to increase significantly among people who had sugary drinks a few times a month or even a few times a week. The stronger association appeared among those who drank them every day.
Researchers aren't sure why sugary drinks could be linked to stomach cancer, although possible explanations include weight gain, hormonal changes, insulin problems, DNA damage, inflammation, or changes in the gut microbiome. The study authors note that more research is needed to understand the connection

People have long experimented with cold exposure in the hope of improving their health and extending their lives. Whether it's taking a cold shower, or plunging into an ice bath, deliberately exposing the body to cold has gained attention as a possible way to improve health. But scientists are still working to understand what happens inside the body. New research may offer an explanation, revealing how exposure to cold could activate metabolic processes that promote healthier cells and potentially extend lifespan.
Muscles are essential to keeping the body healthy and functioning well. In addition to allowing us to move, they help regulate blood sugar, support metabolic health, and protect our joints while helping us remain independent. Yet, as we grow older, muscle strength and size naturally decline. This gradual loss can affect stability, raise the risk of falls, and make it take longer to bounce back after an injury or illness.
The strength of the skeleton is often assessed by measuring bone mineral density, which reflects how well bones can withstand damage and resist fractures. According to research, changes in the skeleton could also provide important clues about cognitive aging. A new study points to a potential connection between reduced spinal bone density, changes in the brain, and a more rapid decline in brain aging.
