Researchers from Norwegian Institute of Public Health suggest that consumption of caffeine in pregnancy is associated with child weight gain

Studying the average caffeine intake in mid-pregnancy of over 50 000 mothers and their children in Norway the researchers found that children of women with an average intake (50 – 199 mg / day), a high intake (200 – 299 mg / day) or a very high intake (300 mg + / day) were more likely to experience excess growth. They further found that any intake of caffeine was associated with increased body mass index and higher risk of overweight at 3 and 5 years. A cup of Starbucks espresso, for example, contains 75mg of caffeine.
