Chinese women, the traditional diet rich in starchy rice and other foods that promote eating a rise in blood sugar levels do not seem to increase colon cancer risk suggests new research of the mother.

The findings in the American Journal of Clinical Nutrition, the body of contradictory statements about whether add foods with an index “high glycemic associated with an increased risk for colon cancer.

Glycemic Index or GI, refers to how quickly rise carbohydrates causes blood sugar levels. GI foods like white bread, white rice and potatoes tends to keep blood sugar levels to rise quickly. With a low GI foods such as lentils, soybeans, yogurt and many high-fiber cereal, blood sugar I laughed, but not as fast and as high as.

relates Related concept called the glycemic load on both the GI and the amount of carbohydrates in foods: low-calorie piece of fruit, for example, a relatively high GI, but still only be small glycemic load.

The idea that a diet with high glycemic load may lead to colon cancer risk contribute to human physiology based on: high blood sugar levels cause the release of the hormone insulin, blood sugar levels in control – called together with the related hormone insulin-like growth factor one – the trigger growth and spread of cancer cells.

In line with those of several studies have shown that people with abnormal type 2 diabetes, people with high blood sugar and insulin levels, get cancer more often than people without diabetes.

So in theory, take a heavy diet with a high GI risk factor for cancer. But studies so far on the issue of conflicting results.

For the new study, researchers 73 000 middle-aged Chinese women for more than a decade older, to find the connection between diet and cancer risk reporting.

Women without cancer aged 40-70 completed questionnaires at baseline, the researchers detailed estimate of total food energy allows its glycemic load diet.

Total of 475 women diagnosed with colon cancer or rectum during the 10 years, the researchers examined them. When the researchers divided study participants into five groups on the glycemic load diet, because they have not found evidence that women are at increased risk of colon cancer with a high glycemic load.

Because rice was among the greatest contribution to women’s glycemic load, the researchers investigated the relationship between the number of servings per day, a woman had their risk of colon cancer.

Again, no clear link, say the researchers, led by Dr. Li Hong-Lan of China, Shanghai Cancer Institute.

Her research has its limits. That all research is based on questionnaires and food, it tends to produce false readings. And while there is no relationship between glycemic load and colorectal cancer in this study, the results can not refute the possible role of high-GI diet and colon cancer development.

However, the researchers point out that many of the studies in GI-cancer link, the so-called “control cases in which patients with colon cancer reported past habits and diet compared with a group of healthy feet.

Only limited inferences can be concluded from this study. Prospective studies such as this, the initially healthy individuals followed over time, we see strong design.

Comments on my team, like most American and European studies found no association between high GI diet and colon cancer. Most studies have focused on women, but also some men.

But the researchers, more research is justified, even on men and different types of carbohydrates from.

Some traditional risk factors for colorectal cancer in older age (most cases occur after age 50), developed according to a first-degree relatives, cancer, and personal history of ulcerative colitis or Crohn’s disease. Research also consistently associated with obesity and smoking, diet high in red meat and processed with an increased risk….
