How many calories does 1 serving (1 g) have?

Matcha tea is a healthy alternative to sugary and caloric drinks: 1 serving of matcha tea only contains 3 calories (Kcal), a very low caloric intake to our daily diet.
The WHO (World Health Organization) establishes a caloric intake for the healthy adult from 2,000 to 2,500 Kcal / day for men and 1,500 to 2,000 Kcal / day for women. According to recent studies, the intake of matcha tea can multiply the loss of calories by four. Green tea contains negative calories, that is, that the absorption process of our body and the energy it needs to process it is greater than the number of calories we eat when we consume food.
