Matters needing attention and key points of lemon:
Lemon should not be eaten with milk. Because the fruit acid in lemon will solidify the protein in milk, which will affect digestion and absorption, which is not conducive to health; Lemon and vinegar have high acidity, so it is not advisable to drink too much on an empty stomach at the same time, otherwise it will easily hurt the stomach; Lemon should not be eaten with carrots, because carrots contain ascorbic acid zymase, which will destroy vitamin C in lemons, and lemons should not be eaten with seafood.
Because vitamin C in lemon can make the metal contained in shrimp, pentavalent arsenic, turn into toxic trivalent arsenic, which is the "arsenic" commonly used to poison people in China costume drama. There is no problem taking vitamin C from natural food, but don't take too many high-dose vitamin C tablets without authorization. In addition, metals tend to accumulate in the heads of seafood, so try not to eat shrimp heads and fish heads.
