Experts advise: obese people have more cancer risk than lean

Obesity will become the first result of cancer

In 2008, the AAAS annual meeting of the Harvard School of Public Health Professor Willett, obesity will become a cancer in the near future, the first result. At present, obesity caused about 14% of people die from cancer, the corresponding proportion of women is 20%.

Obesity is often boasted as "Fa-Fu." In the hungry years, obesity seems to be the performance of wealth and status. However, "Fa-Fu" is not true blessings, it is hidden is not conducive to the health of "bad machine." Study confirmed that not only increase the risk of obesity, diabetes, hypertension, heart disease risk, obesity also increase the risk of cancer.
Reminder: obese people than lean people more cancer


Overweight or obese increases cancer incidence and mortality

In 2007, a British medical journal published a scholar at Oxford University, "Million Women Study" report, the results were shocking: overweight or obese increases cancer incidence and mortality. In the period from 1996 to 2001, the British experts on the 1.2 million 50 to 64-year-old women followed up for five years, there are 45037 obese cancer; follow-up of 7 years, there are 17203 obese people died of cancer. Further analysis found that: obese people are particularly vulnerable to risk of endometrial cancer, esophageal cancer, kidney cancer, leukemia, multiple myeloma, pancreatic cancer, non-Hodgkin's lymphoma, ovarian cancer, breast cancer and colorectal cancer, obesity, women suffer This is 10 kinds of malignant tumors of 1.61 ~ 2.89-fold increased risk.

In addition, the authority of the medical journal "Lancet" published the "obesity increases cancer risk," the latest conclusions of systematic reviews and meta-analysis, involving a total of 282,137 cases of cancer cases and found that:

Male body mass index (BMI) increases with men esophageal adenocarcinoma, thyroid cancer, colon cancer and kidney cancer and other cancer risk was significantly correlated. Body mass index for each additional five, esophageal adenocarcinoma, thyroid cancer, colon cancer and kidney cancer risk increased by 52%, 33%, 24% and 24% respectively.

The increase in BMI of women and women of endometrial cancer, gallbladder cancer, esophageal adenocarcinoma and renal cell carcinoma and other cancer risk was significantly correlated. Body mass index for each additional five, endometrial cancer, gallbladder cancer, esophageal adenocarcinoma and renal cell cancer risk increased by 59%, 59%, 51% and 34%.

Endocrine system, metabolic disorders is the main cause of cancer-causing

Basic research found that obesity is the main mechanism for cancer-causing obesity, metabolic abnormalities lead to changes in the body, especially the endocrine system, metabolic disorders.

Obesity, cancer and other possible mechanisms also include the changes in fat metabolism factors, local inflammation, high blood pressure and lipid peroxidation increase in cancer risk, non-alcoholic fatty liver disease increases the incidence of hepatocellular carcinoma risk of abdominal obesity caused by Gastroesophageal reflux also increases the risk of esophageal adenocarcinoma.

Anti-Cancer: To maintain a dynamic balance to eat

Prevention and treatment of obesity and reducing cancer risk, should avoid excessive gluttonous food, in particular, to avoid long-term repeated bulimia high-fat, high-protein, high-calorie foods. Of course, they should pay attention to maintaining physical activity and exercise, to avoid Landai and the excessive pleasure-seeking.

The Ministry of Health in 2007 Dietary Guidelines issued by Chinese residents put forward a balanced diet, rational nutrition, health promotion eight recommendations that deserve everyone's attention: ' a variety of food, mainly cereals; ' eat more vegetables, fruits and potato: ' regular nurse classes, beans or their products; ' amount regularly eat fish, poultry, eggs, lean meat, less Chi Feirou and Hunyou; ' to balance food intake with physical activity, maintaining appropriate body weight; ' to eat salt and light meals; ' drink Wine should be limited; ' to eat clean and not rotten food.
