Interpretation of anti-cancer diet: say no to high-fat

Tube didn't shut up how serious the consequences of not that she didn't know, one said.

We all know and love to eat meat easier colon, expert opinion, this is only the tip of the iceberg. Recently, Sun Yat-sen University affiliated Education Director, Medicine Professor, Qin Jian in his diet and cancer "lecture, total calories, fat, protein and carbohydrate intake and cancer are intrinsically linked, only have anti-cancer effect of dietary fiber. How to prevent diet cause cancer?

High calorie, high fat intake eco tumor

When speaking of the etiology and prevention of cancer, not excessive "diet" and "love to eat meat" in the keywords.

The most familiar is the prevention and treatment of colorectal cancer must be from the reduction of high fat diet. Can most people only know its a wonder and second, the original fat also and closely related to the occurrence of breast cancer.

"High-fat diet can cause high estrogen and promoting milk-and milk hormone estrogen and is necessary for breast cancer.

"Sun Yat-sen University affiliated Education Director, Medicine Professor, Qin Jian said, love to eat meat may increase the risk of breast cancer, but this is not the only dietary risk factors, if you eat too much of the total calories, breast cancer and colorectal cancer, gallbladder and bile duct cancer, cervical cancer, ovarian cancer, endometrial cancer incidence is increasing.

Research has shown that the total calorie intake per day from 2700 up to 3900 kcal kcal, colon and rectal cancer mortality rates more than twice.

High-calorie diet in women with breast cancer incidence is low-calorie diet area 1.2 times. However, reduce the body's nutritional supply can also cause the body weakness, resistance decreased tumor will still occur.

Recommendation: the total calories consumed can not be too much, nor too small, it is best to control in each daily 2200-2700 kcal.

Fat intake is generally believed that accounted for 16% of the total heat-20% is appropriate, should increase the vegetal fats (such as vegetable oils, etc.). Eat less high cholesterol foods such as shrimps, Blueberry Juice, duck, pork liver, dried shrimp, eggs, beef liver, tripe, crabs, squid, eel, cake, ice cream, full-fat milk.

Excessive amounts of protein and carbohydrates lead to cancer

At the press of impression, rarely heard of protein and carbohydrates and what associated tumors.

In the lectures of Professor Qin Jian, journalists are accidentally get the hint.

He pointed out that, when the dietary protein levels too low, you can promote tumors occur, and when the intake of protein by human normal requirement of 2 ~ 3 times, can also be enhanced chemical substance-induced tumors.

So that protein intake too much or too little is wrong. And animal proteins and plant protein on tumor of some differences. From the study show that animal protein and breast cancer, colorectal cancer, prostate cancer, pancreatic cancer interrelatedtothe relations, plant protein (e.g. beans), but can inhibit tumor. Carbohydrates and tumor study is not very much, but some studies show that sugar and starch and colorectal cancer, colon cancer, rectal cancer, pancreatic cancer and other tumors. Excessive carbohydrates can lead to an excess of total calories, thereby increasing the risk of cancer.

Recommendation: the protein supply per person per day for 70-80g suitable, including soy protein should account for 20%.

Carbohydrate calories should constitute the total calories of 60% to 70%.

Eat food fibre to reduce the incidence of tumors

Perhaps we would ask that you can eat what?, in fact, diet promote tumors, there are also factors in the prevention of cancer, dietary fiber is a panacea.

Qin Jian said that dietary fibre can significantly reduce colorectal cancer, rectal cancer, colon, breast, gastric cancer, esophageal cancer, cervical cancer, pancreatic cancer, oral cavity and pharynx cancer tumor incidence.

Its anti-cancer mechanisms mainly reflected in the lower large intestine of concentration in the carcinogens; reduce toxins in the intestine through time, reduce carcinogens and the contact time between organizations; the impact of certain carcinogenic or production of front carcinogens; regulation of the endocrine system, etc. To colon cancer, for example, when the consumption amount of dietary fiber is 28% (very high) and 15% (high level), the incidence of colon cancer is very low, when the intake of dietary fiber is 5% (low level), colon cancer morbidity is very high.

Recommendations: daily eat more vegetables, fruits and whole grain foods, particularly lemons, citrus fruits, cruciferous vegetables and mushrooms.

The so-called cruciferous vegetables, including broccoli, cabbage, cauliflower, celery, kale, kohlrabi, mustard and turnip.
