Coffee contains a large amount of caffeine so it is often consumed by people to keep the mind awake and improve work efficiency.Many previous studies have shown that drinking coffee regularly can bring many health benefits.
Lung cancer is one of the most common cancers in the world and is the leading cause of cancer death.It is known that smoking is the main risk factor for lung cancer, but there are many other factors related to the development and progress of lung cancer, including genetics, environment and diet.With the high burden of lung cancer, identifying the adjustable factors in the diet for lung cancer is particularly important.
Recently, researchers from the University of Health Sciences in Iran have published an integrated analysis titled "System assessment and general dose analysis - reaction of the Muoc System Studies.Hybrid coffee consumption and risk of lung cancer "in Science Report magazine of Nature magazine.
Studies have shown that the amount of coffee consumed more related to the risk of lung cancer increased by 28% and the analysis of dosage showed that drinking a cup of coffee every day is related to cancer risk.Lungs increased by 6%.
In this synthetic analysis, researchers have systematically reviewed the current evidence of the relationship between coffee consumption and the risk of lung cancer, general analysis of 14 studieshybrid and quantitative relationship between coffee consumption and lung cancer.
A comprehensive analysis of 14 studies shows a significant positive relationship between coffee consumption and the risk of lung cancer, in which the higher amount of coffee consumed is related to the increased risk of lung cancer.28%.
In addition, a specific gender analysis shows that the relationship between coffee consumption and the risk of lung cancer is evident in both men and women, in which women are at higher risk than men.
The researchers also analyzed the impact of smoking and found that smoking did not change the relationship between coffee consumption and the risk of lung cancer regardless of smoking.
An analysis of dosage indicates that increasing the amount of coffee drink one more cup per day is associated with an increase in 6% of the risk of lung cancer.Moreover, the risk of lung cancer increases linearly with daily coffee in about 1-5 cups of coffee a day.
The researchers said that this is the most comprehensive and updated synthetic analysis of coffee consumption and the risk of lung cancer, showing the dimensional relationship between coffee consumption and the risk of lung cancer.
Regarding the potential mechanism, research shows that it may be related to acrylamide in coffee.Coffee is an important source of acrylamide in the diet and is a gene toxic substance.The roasting process increases the acrylamide content in coffee that can damage DNA in the tissues of mammals that cause oxidation stress, thereby forming cancer cells.
However, the researchers emphasized that this synthetic analysis is based on observation studies and cannot establish a causal relationship between coffee consumption and the risk of lung cancer.
