[Health Channel/Comprehensive Report] Lung cancer is a malignant tumor with high morbidity and mortality worldwide. In addition to treatment, nutrition and diet also have an important impact on the recovery and survival of patients.

In this regard, nutritionist Xue Xiaojing reminded that if you want to reduce the risk of lung cancer, it is recommended to choose a Mediterranean diet, take in more dietary fiber, eat more foods containing soy isoflavones, reduce red meat and processed meat, avoid offal foods, excessive retinal Alcohol and beer.

Xue Xiaojing posted on her Facebook fan page "Nutritionist Mother Xiaojing's Life Notes" that in Taiwan, lung cancer accounts for one-fifth (19.3%) of all cancer deaths and has ranked first among the top ten causes of cancer death in China for 18 years. ; According to the latest statistics from the Ministry of Health and Welfare, the number of deaths exceeded 10,000 for the first time, and reached 10,040. It is also the second most common cancer in the country, second only to colorectal cancer.

According to statistics in 2019, the number of lung cancer cases was 16,233, which is equivalent to nearly 45 people suffering from lung cancer in one day.

Eating a Mediterranean diet reduces cancer metastasis

According to research, the Mediterranean diet can reduce the risk of lung cancer, mainly rich in nutrients and phytochemicals, such as beans, nuts and fish rich in polyunsaturated fatty acids, as well as vitamin D and dietary fiber, these nutrients are important for preventing inflammation, promoting Both apoptosis and regulation of the immune system play an important role in reducing the occurrence and metastasis of lung cancer.

Especially in middle-aged and elderly people, the effect of this dietary pattern is more significant.

In addition, olive oil in the Mediterranean diet, rich in monounsaturated fatty acids, helps to reduce the level of LDL cholesterol, thereby reducing the risk of cardiovascular disease and lung cancer.

Moreover, the red wine and tea in the Mediterranean diet pattern are rich in polyphenolic compounds, which have antioxidant and anti-inflammatory effects, can reduce the damage of free radicals to the body, and further reduce the occurrence of lung adenocarcinoma.

Therefore, it is recommended to follow the Mediterranean diet to increase the intake of plant foods such as fruits and vegetables, whole grains, and beans, and reduce the intake of animal foods such as red meat and processed meat.

At the same time, you can eat nuts, olive oil, fish, etc. in moderation to obtain rich nutrients and bioactive substances and reduce the risk of lung cancer.

Increased dietary fiber intake reduces tumor formation

Dietary fiber can help digestion and bowel movements, reducing the risk of constipation and colorectal cancer.

A prospective study by the Japanese Center for Public Health found that increasing the intake of total dietary fiber can reduce the risk of lung cancer in men.

CONCLUSIONS: Dietary fiber intake from vegetables was associated with a reduced risk of lung cancer in men, but not in women.

The study also found that dietary fiber intake was associated with a reduced risk of lung squamous cell carcinoma, inflammation and tumor formation.


​In addition


, studies have also shown that dietary fiber can regulate the balance of intestinal flora, reduce chronic inflammation, increase stool volume and intestinal peristalsis, and help excrete harmful substances and carcinogens in the body, thereby reducing the occurrence of lung adenocarcinoma.

Therefore, it is recommended to increase the intake of foods rich in dietary fiber such as fruits and vegetables, whole grains and nuts.

Long-term consumption of red and processed meat may increase cancer risk

Red meat and processed meat are high-fat, high-cholesterol, and high-sodium foods, and long-term intake can increase the risk of lung cancer.

According to research, a daily intake of 50 grams of red meat and processed meat will increase the risk of lung cancer by 5%, mainly because it contains a lot of fat and cholesterol, and a high-fat and high-cholesterol diet can increase the occurrence and metastasis of lung cancer.

In addition, carcinogens such as nitrite and polycyclic aromatic hydrocarbons in red meat and processed meat are also important reasons for increasing the risk of lung cancer.

Therefore, it is recommended to reduce the intake of red meat and processed meat and other animal foods, especially fast food, snacks, carbonated drinks and other high-fat, high-sugar, high-sodium foods.

Eat soy isoflavones to reduce free radical production

Soy isoflavones have antioxidant and anti-inflammatory effects.

Soy isoflavone intake is associated with a reduced risk of lung cancer, especially in Asian populations, according to a systematic review of studies.

The results of the study found that soybean isoflavones can reduce free radical production and cell damage, thereby reducing the occurrence and metastasis of lung cancer.

In addition, it can reduce serotonin levels, thereby reducing serotonin-related cancer risk.

Therefore, it is recommended that patients with lung adenocarcinoma increase the intake of foods rich in soybean isoflavones such as beans, soy products, and tofu.

However, non-Asians are advised to control it in moderation to avoid excessive intake.

Avoid organ foods, excess retinol, and beer

Offal foods, excessive retinol (vitamin A) and beer/cider are unhealthy foods for the lungs, and long-term intake can increase the risk of lung cancer.

According to a study, a daily intake of 50 grams of offal food will increase the risk of lung cancer by 7%.

The European Prospective Investigation into Cancer and Nutrition study concluded that offal foods, excess vitamin A, and beer/cider can have adverse effects on lung cancer because these foods contain a lot of fat and cholesterol.

More studies have shown that high-fat and high-cholesterol dietary patterns increase the occurrence and metastasis of lung cancer.

In addition, carcinogens such as acetaldehyde in beer/cider are also important reasons for increasing the risk of lung cancer.
