cyst caused by diet
School of Medicine, Family Medicine answered. Yes, diet plays a significant role in the development of abnormal ovarian cysts in women. There is now good evidence to suggest that a diet high in sugars (which includes not only sweets, but starchy foods) may lead to the formation of ovarian cysts. Sugars cause the body to produce insulin, and repeated exposure to sweets can damage insulin production, which is known as insulin resistance.
