Questions surrounding caffeine intake and risk of miscarriage and health of the foetus continue to be raised by pregnant women.
Caffeine consumption equivalent to approximately 3 ½ to 5 cups of tea per day had no effect on birth weight, birth length and head circumference of the baby. A follow-up examinations at age’s eight months, four and seven years also revealed no effect of caffeine consumption on the child’s motor development or intelligence.
Pregnancy hampers caffeine metabolism. For example, in non-pregnant women the break-down of half of the caffeine takes an average of 2.5 – 4.5 hours, 7 hours during mid-pregnancy and 10.5 during the last few weeks of pregnancy. As caffeine retention is longer during pregnancy, women sensitive to caffeine may be affected. As a result a moderate consumption of approximately 3-4 cups a day, is recommended for women during pregnancy.
