Study Links High-Carb and High-Fat Diets to Increased Lung Cancer Risk
- Research indicates that diets rich in carbohydrates and fats may elevate the risk of lung cancer.
- Elevated glycogen levels detected in human lung cancer tissue samples.
- Previous understanding limited diet-cancer link primarily to pancreatic and liver cancers.
It is widely understood that consistently consuming a diet high in carbohydrates and fats is not conducive to optimal health. Traditionally, the primary health concerns associated with such diets were focused on weight gain, elevated cholesterol, diabetes, and other weight-related complications.
However, recent scientific investigations have unveiled a potential connection between glycogen, the molecule responsible for glucose storage, and lung cancer development. This suggests that a diet characterized by high levels of fat and carbohydrates may contribute to the onset of this serious illness.
Lung adenocarcinoma, a subtype of non-small cell lung cancer, represents a significant portion, approximately 40 percent, of all lung cancer diagnoses.
Glycogen’s Role in Lung Cancer
A study examining human tissue specimens discovered notably higher glycogen concentrations in individuals diagnosed with lung adenocarcinoma. Further experiments conducted on mice revealed that increased glycogen levels facilitated the spread and accelerated the growth rate of lung cancer cells.
Conversely, when glycogen availability was restricted in experimental models, tumor proliferation was observed to be limited.

Dietary Sources of Glycogen and Cancer Growth
Glycogen production in the body is primarily fueled by carbohydrate intake. During physical activity, the body utilizes glycogen as an energy source. However, when not immediately required for energy expenditure, glycogen is stored for future use.
Individuals adhering to high-carbohydrate, high-fat diets often accumulate excess glycogen. The combination of high carbohydrate and high fat intake was a key factor in the recent study. Researchers examined groups of mice on different diets: high-carbohydrate, high-fat, a combination of both, and a control diet.
The study revealed that the group of mice consuming both high-carbohydrate and high-fat diets exhibited significantly greater lung cancer progression compared to all other dietary groups tested.
Expanding Understanding of Diet and Cancer
The notion that dietary habits can influence cancer development, particularly low-quality diets rich in carbohydrates and fats, is not entirely novel. Previous research had primarily associated dietary links to cancer with pancreatic and liver malignancies.

Further Research Needed on Glycogen and Lung Cancer
Glycogen accumulation has been identified as a characteristic of cancer cells. While scientists are actively exploring the relationship between glycogen and cancer, further investigation is warranted.
This is particularly true in the context of lung cancer, as elevated glycogen levels were specifically observed in lung adenocarcinoma but not in other forms of lung cancer.
Making Informed Dietary Choices for Lung Health
Nevertheless, the existence of a connection is evident, underscoring the importance of adopting healthy dietary patterns to mitigate the risk of serious health conditions, including lung cancer.
Foods that contribute to high-carbohydrate and high-fat intake, such as red meat and alcohol, should be consumed sparingly.
Prioritizing balanced nutrition will benefit both lung health and overall well-being.
