Ice Sugar Snow Pear Slices promote saliva production and dissolve phlegm; traditional handmade maltose moistens lungs and relieves coughs; Sichuan Jinchuan Snow Pear Syrup concentrate moistens lungs, stops coughs, and dissolves phlegm; Taiwan Madou Green Zanzan Aged Pomelo, among other anti-smog foods, are trending online. But do these products truly combat smog? Is there real evidence they work? Let's explore.
Expert Analysis: PM2.5 particles can directly enter the lungs or bloodstream, triggering related diseases. Food enters the digestive tract and cannot directly "remove" harmful substances from the lungs. Currently, no medical research indicates that any specific food can effectively combat or reduce PM2.5 levels. Therefore, claims that "certain foods can protect against PM2.5" lack scientific basis.
The notion that eating pig's blood detoxifies stems from iron intake converting into black iron sulfide in the body, causing dark stools that are mistaken for expelled "toxins." Studies indicate consuming pig's or duck's blood may reduce absorption of certain toxins and accelerate their elimination, but its effectiveness against lung dust is limited.
Wood ear mushrooms and silver ear mushrooms contain gelatinous components that can clear dust from the digestive tract, but their effectiveness against lung contamination is also limited. Currently, no research indicates that lung-moistening foods like pears have any special efficacy against smog.
Claims that "pork belly contains unsaturated fatty acids that effectively expel fine particulate matter from the lungs" lack scientific basis, according to Fan Zhihong, Associate Professor at the College of Food Science and Nutrition Engineering, China Agricultural University. The unsaturated fatty acid content in pork belly is far lower than that in vegetable oils. If it truly worked, one could simply drink oil. Most anti-smog foods sold online merely offer lung-cleansing or moisturizing benefits.Consumers should be vigilant and not believe merchants' claims of miraculous or extraordinary effects. Is there really a smog video? We'll conclude our introduction here. We trust you now have a clearer understanding. Finally, we sincerely wish you good health and happiness.
