Lung cancer has not typically been considered linked to diet. Yet, recent research has revealed an unexpected factor contributing to lung cancer risk. The mix of sugar and fat in our diets. A diet high in sugar and fat could cause glycogen, a form of stored sugar, to build up in lung tissues. Researchers believe this buildup could potentially set the stage for cancer development.
Glycogen accumulation is key in lung adenocarcinoma, a prevalent and aggressive form of lung cancer. This study reshapes our understanding of the relationship between diet and cancer. Cancer cells alter their energy metabolism to support rapid growth. However, the specific impact of glycogen, which is glucose stored for energy, has been largely overlooked until this research.
The Western diet, which is rich in fats and carbohydrates, seems to prompt a significant accumulation of glycogen in lung tissue. According to researchers, this glycogen acts as a readily available energy source for cancer cells. Lung adenocarcinoma makes up 40% of lung cancer cases globally.
Researchers found that higher glycogen levels in cancer cells correlate with more extensive and aggressive tumor growth. In experiments where mice were fed a diet high in fat and fructose, typical of Western eating habits, glycogen levels increased in the bloodstream and lung tumors started growing. Conversely, reducing glycogen levels led to slower tumor growth. This demonstrates compelling evidence that glycogen production is crucial for the development of tumors in lung adenocarcinoma.
This breakthrough paves the way for innovative approaches in cancer prevention and treatment. Modifying diets or developing medications that target glycogen metabolism may help slow tumor growth in patients with lung adenocarcinoma or those at elevated risk.

Being alone isn't necessarily harmful, but feeling lonely may be. According to a new study, older adults who experience persistent loneliness may face a faster decline in both cognitive and physical health. The researchers found that loneliness remained strongly linked to poorer brain health and an increased risk of early death, regardless of how socially isolated a person was.
Imagine being able to preserve your healthiest blood stem cells while you're young, then using them decades later to help rejuvenate your body. New research in mice suggests it may one day be possible to restore a more youthful blood-forming system and immune system by transplanting young stem cells later in life.
The gut microbiome is the community of trillions of bacteria, fungi and viruses that primarily live in the colon. These tiny organisms help digest food while producing compounds that can influence many aspects of both physical and mental health. Researchers have uncovered a link between specific gut bacteria and biological aging, adding to growing evidence that the gut microbiome may affect how we age.
