When most people think about the causes of lung cancer, smoking is typically the first thing that comes to mind. While smoking is certainly a major risk factor for this type of cancer, it’s important to note that it’s not the only one.

In recent years, researchers have started to uncover more about the link between diet and lung cancer.

Certain dietary patterns and specific foods have been shown to increase the risk of developing lung cancer, even in individuals who have never smoked before.

What Is Lung Cancer?

Lung cancer is a type of cancer that starts in the lungs and can spread to other parts of the body. There are two main types: small cell lung cancer and non-small cell lung cancer.

Non-small cell lung cancer is more common, accounting for about 85% of all lung cancer cases.

According to the American Cancer Society, lung cancer is the leading cause of cancer deaths in the United States. Each year, it is responsible for more deaths than colon, breast, and prostate cancers combined.

The Link Between Diet and Lung Cancer

Research has shown that certain dietary patterns and specific foods can influence the risk of developing lung cancer. Here are some of the key factors:.

High-Fat Diets

A diet that is high in fat, particularly saturated and trans fats, has been linked to an increased risk of lung cancer.

Studies have shown that individuals who consume a diet that is high in these types of fats have a higher risk of developing lung cancer than those who consume a diet that is low in fat.

Processed Meats

Processed meats, such as sausage, bacon, and deli meats, have also been linked to an increased risk of lung cancer. These meats typically contain high levels of nitrates and nitrites, which are additives that have been shown to be carcinogenic.

Red Meat

While some studies have suggested that red meat may not be a significant risk factor for lung cancer, others have found a link between red meat consumption and an increased risk of lung cancer.

One study found that individuals who consumed the most red meat had a 22% higher risk of developing lung cancer than those who consumed the least.

Dairy Products

There is some evidence to suggest that consuming high levels of dairy products, particularly whole milk, may increase the risk of developing lung cancer.

One study found that individuals who consumed the most whole milk had a 32% higher risk of developing lung cancer than those who consumed the least.

Low Fruit and Vegetable Consumption

Consuming a diet that is low in fruits and vegetables has been shown to increase the risk of developing lung cancer. These foods are rich in antioxidants and other compounds that can help protect against cancer.

Alcohol Consumption

Heavy alcohol consumption has been linked to an increased risk of several types of cancer, including lung cancer.

In fact, individuals who consume more than three drinks per day have a higher risk of developing lung cancer than those who do not drink alcohol.

Vitamin Deficiencies

It’s also possible that certain nutrient deficiencies could increase the risk of lung cancer.

For example, a lack of vitamin D has been linked to an increased risk of lung cancer, though more research is needed to fully understand this association.
