The new crown pneumonia epidemic continues. In addition to vaccination, frequent handwashing, and wearing masks, we must pay more attention to self-protection. Dietitian Lin Shihang recommends taking more than 5 nutrients to boost immunity, and taking enough nutrients to defend against invading pathogens through self-defense.
Vitamin A and carotenoids can maintain the integrity of the mucosa and reduce the chance of pathogenic bacteria and viruses entering the body. However, according to the results of the national nutrition survey, the intake of vitamin A and carotenoid nutrients in the Chinese people is still sufficient, and it is not necessary to take a large amount of them.
Vitamin C is a key nutrient for immune cell activity. Adequate intake of vitamin C can help maintain a good immunity. At present, the intake of vitamin C in domestic adults is about 140%; Since the recommended intake is about 1~5%, you can follow the recommendation of the National Health Administration's "My Dinner Plate" to help you get enough vitamin C.
Intestinal bacteria in the intestines will greatly affect the intestinal immune system, and metabolites will also enter the body and affect the systemic immune system. Therefore, taking care of the intestinal flora ecology is very important for immunity. Dietary fiber is a key nutrient for nourishing the intestinal microcosm, providing an energy source for intestinal probiotics, helping to build probiotic flora and regulating immunity.
However, the current dietary fiber intake of Chinese people is very low, about 50% of the recommended amount.
In the past, most of the research on colostrum,How immunoglobulins in formula boost infant immunity. Studies have found that immunoglobulin can regulate immunity and reduce the risk of bacterial infection and respiratory problems; while in children and adults,
; Some studies have also pointed out that lactoferrin can stimulate the activity of intestinal immune cells, so lactoferrin is often used in immune-regulating health foods.
In addition to obtaining it from health food, because lactoferrin and immunoglobulin are heat-labile, there are very few opportunities to obtain them in food. At present, the food that can contain both immunoglobulin and lactoferrin is probably only fresh milk sterilized at 72 degrees HTST. You can also consider drinking fresh milk to supplement immunoglobulin and lactoferrin to help improve the protection.
Lin Shihang added that the above are all nutrients that are closely related to immunity. You can usually take more of them to help build a better protection mechanism for the human body. However, don't forget to wash your hands frequently, wear a mask, and get vaccinated against the new crown, which is still the most important part. .
"Health 2.0" reminds you
In response to the new crown pneumonia epidemic, the CDC will continue to strengthen epidemic monitoring and border control measures, and wear masks as instructed to seek medical treatment as soon as possible, and actively inform doctors of travel history and contact history to facilitate timely diagnosis and notification.
