Pursuing a high-fiber and low-fat diet does not help women aged 50 to 79 to prevent breast cancer, colorectal cancer, heart disease and stroke? According to an unprecedented large-scale study in the United States, the so-called "low-fat diet" does not help prevent heart disease and cancer. The general perception in the past is quite different.
Low-fat and normal diet have no difference in cancer risk
The New York Times reported on the 8th that the U.S. federal government spent 415 million U.S. dollars (approximately 13 billion Taiwan dollars) to treat nearly 49,000 people between the ages of 50 and 79. Women are studied for up to eight years. It was found that those assigned to a low-fat diet had no different rates of breast cancer, colorectal cancer, heart disease, and stroke than those assigned to a no-restriction diet.
Medical experts pointed out that despite the fact that 48,835 women who switched to low-fat diets between the ages of 50 and 79 had a lower chance of developing breast cancer than women who did not change their eating habits Nine percent.
But statistically, experts don't think the difference is large enough to be of any significance. For example, among 10,000 women, forty-two women who ate a low-fat diet developed breast cancer a year, compared with forty-five women who maintained a normal diet.
The researchers agree that the findings illustrate the futility of advising people to follow a low-fat diet to reduce their risk of heart disease and cancer. For this reason, many medical researchers said that the best dietary advice now is to follow the guidelines set by the US federal government for a healthy diet, that is, reduce the intake of saturated and trans fats, and eat more grains, vegetables and fruits.
Domestic experts agree that the most reference value of this study is to remind everyone: maintaining health can not only rely on diet or fat control.
Zhao Qiang, director of the nutrition department of Mackay Hospital, pointed out that "lifestyle diseases" means that health maintenance is no longer simply viewed from the perspective of how to eat. From a nutritional point of view, "there are no wrong foods, only wrong combinations." In order to clarify the role of a single nutrient, many studies may not be able to see the whole picture of the overall nutritional intake. It leaves people who follow the principles of healthy eating at a loss."
