Since the outbreak of COVID-19 in 2020, the public has paid more attention to health food that can regulate immunity, but in addition to supplementing health food, is it possible to improve immunity and fight against many potential infection threats through diet? For example, nutritionists say that there are many nutrients in the diet that help maintain and regulate immunity. For example, yogurt is rich in probiotics, which can help improve immunity.
Nutritionist Lin Shihang pointed out that probiotics are very important to human health, but there are not many ways to supplement probiotics. Many people choose to directly ingest probiotic health food, such as probiotic capsules or probiotic powder. As the weather gets hotter, a cold yogurt can be a good source of probiotics.
CNS3058 national standard stipulates that yogurt should exceed 10 million CFU per gram of active lactic acid bacteria, and some domestic yogurt even exceed 100 million CFU per gram of active lactic acid bacteria, that is,
Yogurt is one of the earliest sources of probiotics intake by human beings. It has a history of more than 5,000 years of consumption and has evolved good bacteria to adapt to the intestines. The International Dairy Farmers Association stipulates that fermented milk should contain Streptococcus thermophiles (Streptococcus thermophiles) and Bulgarian milk. Bacillus (Lactobacillus bulgaricus) two species, but Taiwan's national standard does not have this restriction.
Lin Shihang said that during the fermentation process, Streptococcus thermophilus will grow rapidly and produce acid, which is conducive to the growth of Lactobacillus bulgaricus, which willThe milk protein is dissolved to provide the amino acids required by Streptococcus thermophilus. These two bacteria promote the growth of each other and continue to ferment, and the pH value drops to promote the aggregation of milk proteins, which can give yogurt and yogurt a thick appearance. .
The strains added to yogurt are not only the basal Streptococcus thermophilus and Lactobacillus bulgaricus, but also many functional strains, such as Lactobacillus acidophilus, Bifidobacterium longum, also known as Long root ( Bifidobacterium longum and Lactobacillus rhamnosus, etc., strains with immune regulation effect, can greatly improve the health value of yogurt, multi-strain symbiotic fermentation, strains synergistically grow mutually beneficially, and also produce more abundant nutrient content.
Taking Lactobacillusacidophilus and Bifidobacteriumlongum as examples, previous studies used cholera vaccine to induce immune response, and found that
In addition, some studies have supplemented Bifidobacterium longum with tube-fed silver-haired elders and injected influenza vaccine to test the effect of probiotics. The results found that they can regulate IgA, IgG antibodies and natural killer cells in the body, helping to regulate immunity.
In addition to the above strains, the basal fermenting bacteria Streptococcus thermophilus (Streptococcus thermophilus) is alsoThe strains of GRX02 were screened out, and animal experiments have also been found in the past to have the effect of delaying alcoholic liver damage and improving antioxidant capacity.
Therefore, when choosing yogurt, you can choose products with these functional strains or strains added, not only the taste but also the health, especially during the epidemic, to enhance the protection and live a new life of epidemic prevention every day.
Yogurt is a good way to supplement probiotics. When choosing yogurt, it is not only delicious, but also the pursuit of health benefits. Since each strain has different effects, when choosing yogurt, you can choose a yogurt fermented with multiple strains, and choose a strain that can colonize different intestinal passages, which can exert more health effects.
Sugar is the public enemy of health. It not only causes obesity and other problems, but also studies have speculated that excessive intake of sugar may indirectly affect the immune system by causing obesity, high blood sugar and other problems, which may reduce resistance. Therefore, it is recommended to The less sugar in your diet, the better.
But yogurt tastes sour after fermentation. Many yogurts will add a lot of sugar to suppress the sour taste, which may cause unnecessary and excessive sugar intake and affect health, so it is recommended by nutritionists.
If you really want a little sweetness, .
In the past, yogurt mostly added food additives such as thickener colloids or spices to enhance the taste and aroma. Although these food additives are in compliance with food regulations, is it acceptable to not add unnecessary additives? ?
This is also the concept of the clean label wave, which is also driving the progress of the food industry. Therefore, keep up with the global wave of less and no additives.
Many yogurts use milk powder for reductive fermentation. The milk powder goes through processes such as spray drying and water reduction, which may change the flavor, and the import shipping process will also have a large amount of carbon emissions. Yes, it can support dairy farming. It also reduces carbon emissions and contributes to environmental sustainability.
Lin Shihang also said that yogurt can also be used in dishes to help serve as a sauce for salads. It is also a good ingredient for healthy afternoon tea when you are hungry in the afternoon. Modern afternoon tea is generally unhealthy, so you can choose sugar-free. Add-free fresh milk yogurt, seasoned with nuts and a little fruit pulp, helps replenish functional bacteria and improve immunity.
And not only the new coronavirus pneumonia virus, in fact, there are many pathogenic bacteria and viruses in life, such as: influenza in autumn and winter, pediatric enterovirus, etc., are threatening our life, it is recommended to increase our own protection at all times, to help defend against health threats.
"Health 2.0" reminds you
In response to the new crown pneumonia epidemic, the CDC continues to strengthen epidemic monitoring and border control measures, and wear a mask as instructed to seek medical treatment as soon as possible, and actively inform the doctor of travel history and contact history, so as to facilitate timely Diagnosis and notification.
