The World Health Organization recommends a limit of 300mg of intake of caffeine per day during pregnancy but the limit is 200mg in some of the countries. A study at the Swedish university suggests that caffeine from any source, even in the smallest quantity, reduces birth and weight of a newborn baby.
The average-expected weight of a baby is 3.6 kilograms, which on increasing caffeine intake can be reduced considerably. According to researchers of Sahlgrenska University Hospital of Sweden, 21-28 grams of body weight is lost per 100 milligrams caffeine per day.
