In winter, the biggest fear is the flu. Do you know what foods can prevent the flu? Let's find out below. Many people have heard the saying "drinking yogurt can prevent colds." Is this statement really reliable?
Can drinking yogurt prevent colds?
Lactic acid bacteria drinks sold on the market generally use bacterial strains such as Lactobacillus rhamnosus 1073R-1, Lactobacillus reuteri, and Lactobacillus casei FK-23, which have the effect of enhancing the immune function of NK cells. NK cells are the first immune cells activated after a virus invades the human body. At the same time, these bacterial strains have also been confirmed to suppress the worsening of symptoms after infection.
Although the bacterial strains are different, basic lactic acid bacteria can stimulate the activation of the human body's immune function, enhancing a person's defensive capabilities. Furthermore, some studies have found that certain lactic acid bacteria can not only activate NK cells but also stimulate the activation of all immune cells, thereby improving the body's immune function.
Lactic acid bacteria can enhance the body's defense to prevent flu infection
According to research by the National Institute of Infectious Diseases in Japan, drinking beverages rich in lactic acid bacteria is not only effective for preventing the flu but also suppresses symptoms of colds and flu such as coughing and fever. After examining the blood, it was also found that it can inhibit the reproduction of viruses that have already entered the human body, promoting recovery from the flu and colds.
Researchers state that plasma lactic acid bacteria can awaken the human immune system at the same time a virus invades the body, while also enhancing the defensive power of each cell, preventing the virus from reproducing within the body.
