There is no established medical evidence that iced drinks, frozen foods, or raw foods directly cause ovarian cysts. However, persistently chilling the lower abdomen can stagnate pelvic blood flow, which may worsen symptoms caused by an existing cyst, such as menstrual pain, abdominal bloating, and menstrual irregularity. In particular, if you have an endometrioma, it helps to reduce processed and high-fat foods that can affect estrogen levels and to follow an anti-inflammatory diet centered on vegetables, whole grains, and oily fish. Polyphenol-rich foods such as green tea, broccoli, and berries are also known to be beneficial for the ovarian environment.
