Cucumbers contain more vitamins, including more vitamin C, so they are not suitable for cooking with shrimps. It’s better to eat them separately.

Eating shrimps and tomatoes together will cause poisoning. The reason is that tomatoes contain too much vitamin C. Vitamin C and shrimps are eaten together, and combined with gastric juice and intestinal juice, a chemical reaction will occur, producing arsenic ( That is the main component of arsenic), which can poison people. Note that it is not obvious if you eat too little, but news of serious poisoning and rescue after eating too much often happens.
