Long-term big mouth to eat meat, high protein diet has been questioned, some studies found that the diet will hurt the kidneys and lead to the occurrence of colorectal cancer; Now, the latest research indicates that eating red meat (especially processed), and type II diabetes.
Eat less red meat than women, women who eat red meat nearly a third have a high risk of exponential type II diabetes; in large health research study, eat bacon, hot dogs and processed meat women, suffering from type II diabetes risk 43% higher.
This is from the Harvard Medical School study group's latest study found that published in the September issue of the "Diabetes Care" journal.
Processing products induced insulin resistance
The researchers followed more than 37,000 women over 45 years, the average observation time of eight years; all the women are joining before the experiment, fill out a detailed questionnaire, and all without heart disease, cancer, or type II diabetes.
In the follow-up after, there are 1,560 female suffering from type II diabetes, after adjusting for other related form of diabetes risk factors such as age, weight, and physical activity, researchers continue to find the amount of consumption of red meat processing, induced type II diabetes and the relationship between.
Tested once a week compared to only eat red meat the women, more than five times a week to eat red meat the women were found in the high diabetes risk index by 29%; while the same contrast in the processing of meat, the risk index surged to 43%.
Yiqing Song, MD, led the research team that used to process meat preservatives, additives, and other chemical components, including nitrate and nitrite, or even formed in the process of chemical substances, which may have induced insulin resistance.
In addition, iron may play a key role in red and processed meat is rich in iron, while previous studies have shown that high iron concentration and has been associated with type II diabetes; In this experiment, compared with the diet the small amount of iron women, the highest amount of iron intake of women with high risk of developing diabetes by 46%.
However, Song, MD, the team said it because the ingestion of red meat or processed meat, and the mechanism of type II diabetes remains uncertain, requiring further study.
Long-term studies of diabetes, said Frank Hu, MD, the latest research findings and his previous findings and other people the same; Hu, MD, of all kinds of different dietary factors have long to type II diabetes.
In his recent study published in last month, mainly specializes in sugary drinks, studies have shown that regular consumption of high fructose syrup to flavor the soda, the risk of diabetes 80% higher.
Hu, MD, refined sugar, refined flour, and hydrogenated lipids, increased diabetes risk appears to be the culprit; prevention and fight against diabetes, the most important food, is the nuts and fiber-rich foods such as whole grains.
He noted that the vision is very clear, but there are still many unanswered questions, dairy products are still very controversial; some studies show a protective effect it might, but its protective effect compared with nuts and whole grains, are still inferior to many .
Hu, MD, will cause a surge in blood sugar was those with high blood sugar factor (GI value) of food, which is worsening diabetes villain; low-carbohydrate, high protein diet also have to avoid the high GI value of food; However, Hu, MD, these are not a good choice for reducing the risk of diabetes.
He said that these dietary patterns, fiber and whole grains are low proportion, which are phytochemicals, minerals and an important source of antioxidants; these are rich in dietary patterns of the saturated fat; Hu, MD Harvard Medical School in Boston School of Public Health associate professor of nutritional epidemiology cum.
American Diabetes Association President Robert Rizza, MD, when the researchers identify a single food and diabetes risk is related, it is very important right, but the "weight control" and "movement", it was a long-proven low-risk enough to risk two ways.
He said that we can now find a lower risk of suffering from type II diabetes, the most powerful evidence is to maintain the body's activities, and maintaining a healthy weight, reduce saturated and hydrogenated fats, as, and to increase food vegetables important step for the process, we do not want people to overlook the importance of a comprehensive healthy lifestyle.
