Whats the link between multiple pregnancies and IGF-1 levels?
Levels of IGF-1, a hormone that can raise cancer risk when levels are too high, fell as the number of pregnancies increased for women in this study. Women who had been through at least four pregnancies had IGF-1 levels that were 14% lower on average than their peers who had fewer children. What link was discovered between milk proteins and IGF-1 levels? It’s not clear at this point whether milk, or a particular component of milk, is the culprit. It was found that IGF-1 levels rose along with women’s intake of protein, especially from milk. There was no association between IGF-1 levels and vegetable protein intake. Yogurt, cheese and ice cream also had no association with the hormone.
