A new study by researchers in Southern California has sparked debate in the scientific community, as it suggests that consuming fresh fruits, vegetables and whole grains may be linked to an increased risk of lung cancer at a young age - a finding that contradicts the current consensus on healthy diets.
A disease still mainly linked to smoking
In the UK, around 48 people are diagnosed with lung cancer each year, making it one of the most common forms of cancer in the country. In the vast majority of cases, the main cause remains smoking.
However, in recent years, an increase in cases has been observed in people who have never smoked, especially under the age of 50. Today, about 20% of diagnoses fall into this category, and this figure is expected to increase further.
Previous studies have linked this phenomenon to air pollution and exposure to chemicals that affect hormones.
Doubts about the role of pesticides in the diet
The new study suggests that diet may also play a role, mainly due to pesticides used in agriculture.
According to lead author Dr. Jorge Nieva from the University of Southern California, some data suggests that young non-smokers who consume more foods considered “healthy” may have a higher risk of developing lung cancer.
He points out that mass-produced fruits, vegetables and grains can contain more pesticide residues compared to products like meat or dairy.
What the study showed
The researchers analyzed 187 patients diagnosed with lung cancer before the age of 50. Most of them had never smoked and the form of the disease differed from the usual one associated with smoking.
The participants' diets were assessed using the Healthy Eating Index. The results showed that they consumed more fruits, vegetables, and whole grains than the population average.
However, the researchers did not directly measure pesticide levels in food, but relied on existing data on their use in agricultural crops.
Debate among experts
Some experts have been skeptical of the study's conclusions, noting that other factors - such as age and lack of smoking - could influence the observed results.
According to them, there is not yet enough evidence to establish a direct causal link between diet and lung cancer.
Other experts emphasize that smoking remains the main risk factor, while the benefits of consuming fruits and vegetables are well-known and documented.
The issue of pesticides and international regulations
Many pesticides are linked to adverse health effects, including DNA damage and hormonal disruption. Some substances are banned in various countries, but continue to be used in some other countries.
Experts emphasize that more in-depth research is needed to understand whether and which pesticides may have an impact on cancer risk.
While the study opens a new debate on environmental factors and diet, specialists emphasize that there is no reason to avoid fruits and vegetables. On the contrary, their health benefits remain indisputable, while smoking continues to be the greatest risk factor for lung cancer. /GazetaExpress/
