Fat and tumour

Fat and tumour
The relation between fat and tumour may be to study the most thorough factor in the meal. The present unanimous view is the fatty emergence which promotes cancer of colon and breast cancer. The investigation result of epidemic disease proves the fatty meals of absorption of prostate cancer has something to do. U.S.A. investigated the mortality of the prostate cancer of 3056 counties in 1978, they ate a lot of areas such as oil, beef, pork, egg, milk product of food with rich lipoprotein. Fatty to influence the intersection of large intestine and mechanism that cancer have illness coming on, main because fatty to enable the bile of liver secrete increasing, elementary bile acid detest oxygen afford to change under the function of bacterium gallbladder acid and stone gallbladder sour in intestine in the bile. Take off oxygen gallbladder acid and stone gallbladder sour to urge the intersection of cancer and material. The foreign scholar compares 7 correctly with the corn oil of different density, 12 - two methyl benzene third Zhyuan (DMBA) Influence on carcinogenic function. Find the high oil feed can promote DMBA to bring out fibrous adenoma and gland cancer, and take place the time of tumour is short. The analysis of fatty acid explains in the feed oil compositions influence the composition of fatty acid in the mammary gland in the breast tissue, take in it mainly as the high corn oil feed of unsaturated fatty acid, unsaturated fatty acid increases in the breast tissue, especially the inferior oil acid increases. Prove, the oil of high corn promotes bringing out the function of mammary gland tumour of DMBA according to the things happened of tumour, the oil of high corn promotes the tumour incidence relatively tallly. Polyunsaturated fatty acid, mainly can promote big mouse and sub mouse to transplant the growth of breast cancer for the inferior oil acid. In the relation between fat and cancer, cholesterol is the noteworthy question. Discover it is relatively tall that the probability of cancer takes place to the low crowd of total cholesterol of serum, especially cancer of colon, secondly it is lung cancer, cervical cancer and breast cancer. But report serum cholesterol level has nothing to do with tumour. Study to find total cholesterol level of blood plasma presents obvious positive correlation with the mortality of many kinds of main cancers in ecology of 65 counties in our country. But further prove polyunsaturated fatty acid can promote the carcinogenic course for the vegetable oil of the main fact. So should put emphasis on reducing the absorption of the total fat of meal in giving protection against cancer the meal.
