Can milk consumption increase the risk of twins?

According to a study headed by OB-GYN Gary Steinman at New York's Long Island Jewish Medical Center, women who drink milk or eat any kind of dairy products are five times as likely to have multiple-birth pregnancies as those who do not. The researchers postulate that growth hormone (bGH) given to cows to boost milk production may be one of the reasons for the increase. Three in one hundred American women give birth to twins.
