WEB DESK: A small amount of Walnuts a day can slow the growth of tumours by reducing blood supply to the tumour, noticeably slowing down its growth.
Walnuts contain Omger-3 fatty acids and they can help slow the spread of cancer tumours.
Doctor Christos Mantzoros of Harvard Medical School carried out a first of its kind study to observe the impact of walnuts on micro-ribonucleic acids (miRNA), which control how genes mold to environmental factors.
‘Our research demonstrates that a walnut diet causes significant changes in the expression profile of miRNAs in colorectal cancer tissue.’ said Doctor Mantzoros.
Compounds in walnuts cause more Omega-3 fatty acids to assemble in tumour cells, he added.
Researchers fed a group of mice with 57gram of walnuts per day for humans and second group of mice was fed a controlled diet without walnuts.
After 25 days researchers found out that, mice with walnuts in their diet had miRNA that affects cancer cell swelling, blood supply and rapid increase.
The tumours of mice were fed with diet consisting of walnuts were found to have 10 times the amount of total Omega-3 fatty acids compared to the mouse that were fed with controlled diet with no walnuts.
.However, the studies were conducted on lab animals the results may vary in the case of human subjects.
The study published in the Jouranl of Nutritional Biochemistry.
Bowel cancer or colorectal cancer is the third most common type of cancer in the world and after lungs cancer it is the second leading cause of death in Western Countries.
In Birtian 41,581 people were identified with bowel cancer in 2011 and in the coming year 16,187 people died from the disease.
In US, the American Cancer Society estimated that there will be 132,700 new cases of bowel cancer in 2015 and it will cause 49,700 deaths.
Research has shown that 30-50 percent of bowel cancer in men and 20 percent in women can be avoided by consuming healthier diet and lifestyle.
Walnuts contain a decent amount of ALA-2.5 grams per ounce as well as a diverse amount of antioxidants, (3.7 mmol/ounce), and numerous vitamin and minerals.
