  • Lung cancer is the second most common cancer within the world, with about 2 million people diagnosed each year.
  • Prevention for lung cancer includes eating a balanced diet rich in fruits and vegetables.
  • Researchers from Okayama University discovered juice from the Japanese sarunashi fresh fruit could help prevent and reduce lung cancer.

Lung malignancy is the second most common cancer in the world. About 2 mil people are identified and 1 . 8 million die through lung malignancy yearly.

Prevention measures for lung cancer include quitting smoking , avoiding secondhand smoke , and eating a diet rich in fresh fruits and veggies .

Previous research has indicated that fruits and vegetables containing certain antioxidants may help lower a person’s lung cancer risk .

Now, researchers from Okayama College in Japan say they have found evidence that will ingesting fruit juice from the sarunashi fruit grown within Japan can help avoid and reduce lung malignancy via a mouse model.

The study was recently published in the journal Genes plus Environment .

Sarunashi (Actinidia arguta) will be an edible fruit grown in certain parts of The japanese, Northern China, the Korean peninsula, and the Russian Far East.

Outside of Japan, sarunashi is usually also known as the hardy kiwi, kiwi berry, and Siberian gooseberry.

The fresh fruit has a sweet taste similar to that of a standard kiwifruit . It is normally green in color plus unlike kiwifruit does not have to be peeled to be eaten.

Previous research classifies sarunashi as a superfood as it contains more than 20 essential nutrients and numerous vitamins , including high contents associated with vitamin C and lutein .

Other past studies show the particular kiwi fruit to be a rich source of anti-oxidants .

The kiwi berry offers previously been studied as a potential preventive measure with regard to cancer.

According in order to Dr . Sakae Arimoto-Kobayashi , an associate professor within the faculty of pharmaceutical sciences at Okayama University or college and the lead author of this research, researchers decided to study the effect of sarunashi on lung cancer because as lung cancer may be the most common cause of cancer-related death within Japan

“Old people in the source area of sarunashi, Maniwa county in Okayama, traditionally eat it and say ‘sarunashi is good for health, ’” she explained to Medical Information Today . “Components within sarunashi juice enhance (the) repair-process associated with damaged DNA to prevent lung cells from becoming cancer. And components in sarunashi fruit juice prevent the growth of cancer cells. ”

The research team used a mouse model to study the effect of sarunashi juice on lung cancer tissues. Mice were injected with NNK , a carcinogen found within tobacco products, to cause the mice to grow lung cancer tumors.

During the study, scientists reported that the particular number of growth nodules in mouse lungs injected along with NNK and given sarunashi juice had been significantly reduce than within mice not given fruit juice.

Researchers also studied other aspects of sarunashi juice and its effect on lung cancer tissue, such as the polyphenolic compound isoquercetin (isoQ).

In a prior study , the study team examined the result associated with sarunashi fruit juice on inflammation , mutagenesis , plus the formation of cancers on the skin.

In this new study, researchers further looked at isoQ as the potential anticarcinogen . Scientists found rodents given isoQ during the research also had reduced nodules in their lung area.

Medical News Today also spoke with Doctor Mahmud Kara , a functional medicine expert and founder of KaraMD — a line of digestive support, heart health, plus anti-inflammatory supplements to support full-body health, about this study.

He agrees with the particular study’s conclusions on how diet plan plays a crucial role in the development of chronic diseases.

“Many associated with the lifestyle habits or modifiable risk factors that are within our control, such as diet , exercise , and stress reduction , play an important role in many wellness areas, but perhaps the particular most important is the prevention of chronic diseases, ” he explains. “It’s important to consider these modifiable risk factors and make necessary adjustments, especially if other risk aspects outside of your control (e. g. genetics ) put you at higher risk regarding developing malignancy or some other chronic illnesses. ”

When asked how sarunashi juice might help prevent plus reduce lung cancer, Kara said the particular fruit’s antioxidant properties assist when this comes to combating free radical damage at the cellular level caused by oxidative stress .

“Combating oxidative stress is an important part associated with chronic disease prevention, ” he added. “Similarly, combating chronic inflammation is equally as essential when it comes to the prevention of chronic illness. These two health areas, reducing oxidative tension and decreasing inflammation, could be two potential reasons why sarunashi helps prevent and decrease lung cancer. ”

If you do not have access to sarunashi fruit, Kara says there are many additional foods that also provide powerful antioxidants and anti-inflammatories, including:

“While consuming certain foods does not guarantee that a person won’t develop a chronic disease or even cancer, it all goes back to taking preventive measures in order to address the particular modifiable danger factors which are within your own control, ” Kara states.

This individual adds when it comes to food, it’s furthermore important to focus on what not to eat.

“Foods that are pro-inflammatory or contribute to oxidative stress should be avoided whenever possible, ” Kara explains. “These foods consist of but are not limited in order to trans-fat , artificial sugars , refined carbohydrates , along with other foods that contain preservatives or additives . ”

“Research like this helps further our own understanding of exactly how making simple lifestyle changes — (such as) eating the right food items and staying away from the wrong foods — can make a significant impact whenever it arrives to overall health and reducing the risk for persistent disease, ” he additional.
