New research has found that people with lactose intolerance stand at a lower risk of developing lung, breast and ovarian cancers. Lactose intolerance is defined as the inability to digest lactose, a sugar found in milk and to a lesser extent dairy products.
"We found that people with lactose intolerance, who typically consume low amounts of milk and other dairy products, have a reduced risk of lung, breast and ovarian cancers", says Jianguang Ji, associate professor at the Lund University in Sweden.
"The risk of cancer was not reduced in relatives of people with lactose intolerance, which indicates that protection against these cancers is related to diet. However, it would be wrong to conclude that milk is a risk factor for these cancers", Jianguang Ji added.
The study inquired if low consumption of milk and other dairy products prevents lactose-intolerant people against breast and ovarian cancers. It identified 22, 788 individuals with lactose intolerance.
The results showed that risks of lung cancer, breast cancer and ovarian cancer were significantly lower in people with lactose intolerance as compared to people without it. This was irrespective of country of birth and gender.
