Got Milk? Want twins?
A recent article in Journal of Reproductive Medicine found that women who consume milk are five times more likely than vegans to conceive twins. The suspected culprit is insulin-like growth factor (IGF), which is released from animals’ livers in response to growth hormone and finds its way into their milk. Levels of the hormone are about 13 percent lower in vegan women than in women who eat dairy, the team suggests.
Theoretically, hormone-free milk should contain a lower amount of IGF, as well. So, if you’re not interested in multiplying your family at a rapid rate, especially if twins run in your family, you might want to check out organic milk. Or even better, find a local source for raw milk.
