Yangmei is a seasonal fruit in summer. As early as the Three Kingdoms period, there were stories about Yangmei, and the idiom "watching for plum blossoms to quench thirst" originated from the story of Cao Cao leading troops. Although Yangmei may not be very big, it has rich juice, sweet and sour taste, and high nutritional value. There are many varieties of Yangmei in China, including water chestnut seeds, Ding'ao plum, Dong'ao big Yangmei, late rice Yangmei, large leaf slender stem Yangmei, small leaf slender stem Yangmei, and Xishan Wumei, among others. Yuyao, Zhejiang is particularly prolific. Yangmei is rich in citric acid, various vitamins, dietary fiber, and minerals, among which the content of calcium, phosphorus, and iron is more than 10 times higher than other fruits. According to measurements, every 100 grams of Yangmei contains 0.8 grams of protein, 9 milligrams of vitamin C, 14 milligrams of calcium, 149 milligrams of potassium, 1 milligrams of iron, and 10 milligrams of magnesium. Yangmei is not only a good fruit for fresh consumption, but also has certain health benefits for the three high population in summer. Due to its sweet and sour taste and warm nature, it has functions such as generating fluids, quenching thirst, harmonizing the stomach, promoting kidney function, diuresis, and relieving heat. Li Shizhen, a medical expert in the Ming Dynasty, recorded in the "Compendium of Materia Medica" that "Yangmei has a sweet and sour taste, a warm nature, and is non-toxic. It can quench thirst, harmonize with the five organs, cleanse the stomach and intestines, and eliminate annoyance and evil qi." The "Kaibao Bencao" records that Yangmei "mainly removes phlegm, stops vomiting, and relieves diarrhea, and clears food and drinks. Yangmei has extremely high medicinal value, and its fruit, kernel, leaves, and skin can all be used as medicine. Modern medicine has found that the fruit acid in Yangmei not only stimulates appetite and promotes diuresis, but also helps with digestion and summer heat relief. It can also inhibit the conversion of sugar to fat, which is beneficial for weight loss. The flavonoids and anthocyanins with flavonoid like structures contained in its fruit have antioxidant, blood lipid regulating, cholesterol lowering, and blood glucose lowering effects, making it one of the preferred fruits for people with high blood sugar, hyperlipidemia, and hyperlipidemia. Yangmei paired with seafood and arsenic? It is rumored online that the vitamin C contained in Yangmei will react with arsenic compounds in seafood to produce arsenic trioxide, also known as arsenic. This statement has been popular for a few years, claiming that eating seafood with lemon rich in vitamin C can produce arsenic and lead to poisoning. Actually, this statement is incorrect. We can make a hypothesis that based on the content of relevant compounds in seafood, only 10 kilograms of seafood may contain 1 milligrams of arsenic. If arsenic and vitamin C in seafood undergo a complete chemical reaction, it may take eating hundreds of kilograms of seafood at once to reach the toxic level. This also requires sufficient intake of vitamin C and participation in chemical reactions, which means eating a large amount of fruits containing vitamin C at the same time. In fact, even if you eat 10 kilograms of seafood, it is impossible to simultaneously consume sufficient amounts of vitamin C and react with it. So this statement cannot withstand scrutiny. We know that most fruits are rich in vitamin C. If the rumors are true, then all fruits and juices should not be eaten with seafood. (New Society)
