A recent research report recently published in the US "Archives of Internal Medicine" points out that focusing on dietary fiber intake in the diet, especially dietary fiber in whole grain foods, will help reduce the risk of heart disease, infection and respiratory diseases. mortality rate.
The study found that people who consume more dietary fiber in their daily diet have a 22% lower mortality rate from various diseases than those who consume less. This is mainly due to the cereal fiber in cereals. Not the fiber found in fruits and vegetables.
As we all know, previous relevant studies have focused on exploring the association between fiber intake and cardiovascular disease, but few studies have explored the relationship between dietary fiber and mortality. The American Institute for Cancer Research study expands on dietary research and concludes there is a link between dietary fiber intake and reduced mortality.
Foods rich in dietary fiber help lower blood cholesterol and blood sugar levels, which is why dietary fiber is beneficial to heart health. However, the exact mechanism by which dietary fiber helps reduce lung disease and infection mortality is unknown. . Since most of the above-mentioned diseases have a tendency of inflammatory reaction, it can be speculated that the reason why dietary fiber reduces mortality should be related to some of its anti-inflammatory properties, and heart disease is also considered to be accompanied by inflammatory reaction. The researchers also pointed out that people who consume more dietary fiber show overall health characteristics, which may also be a reason for the reduced mortality from various diseases in this group of people.
The study began in 1995-1996 and investigated the frequency of food intake in 219,123 men and 168,999 women respectively. It was followed for 9 years, during which 20,126 men and 11,330 women died one after another.
The results found: People who consume more dietary fiber in their daily diet have a lower mortality rate. The average daily dietary fiber intake of male subjects is 13-29 grams, and that of female subjects is 13-29 grams. 11-26 grams, among which those with higher intakes had a 24%-56% reduction in mortality from heart disease, infection and respiratory diseases for men and a 34%-59% reduction for women.
People with high dietary fiber intake have higher education background, good self-evaluation of health awareness, lower BMI value, more active activity level, higher use rate of menopausal hormone therapy among women, less smoking, Low alcohol consumption and a habit of eating red meat.
However, after removing the influence of these factors, there is still a clear correlation between the survival rate of this group of people and higher dietary fiber intake.
What’s more noteworthy and surprising is that dietary fiber has a protective effect against respiratory disease and infection, and this effect appears to be greater than its benefit against heart attack and stroke.
Therefore, consuming more dietary fiber, especially dietary fiber from whole grain foods, will help reduce mortality from various diseases, not just its previously known benefits for cardiovascular disease.
my country's "Dietary Guidelines for Chinese Residents" recommends that normal adults consume 25g to 30g of dietary fiber per day, and 85g of whole grain foods per day under the premise of a certain staple food intake. However, from the current point of view, this standard can be met. There are not many people.
