Green porridge instead of cocoa? Matcha breakfasts cost little but can ruin sleep

A teaspoon of matcha stirred into oatmeal or yogurt costs only about two Czech crowns per serving. The green tea powder can give breakfast an appealing color and add nutrients, but it is not simply a substitute for cocoa for schoolchildren.

Matcha contains caffeine, which can make children nervous or nauseated. Most importantly, it can seriously interfere with falling asleep in the evening.
