If you want to conceive and avoid abnormal menstruation, you should eat fewer carrots.
According to research from the Johns Hopkins School of Medicine, excessive carotene can affect the synthesis and secretion of progesterone in the ovaries. In some cases, it can even lead to amenorrhea, anovulation, or irregular menstrual cycles.
This condition was first discovered in patients with anorexia nervosa. Even though they did not eat and had no menstruation, blood tests revealed high levels of carotene in their blood. Later, it was also found in some female patients who were not suffering from anorexia nervosa. Consuming large amounts of carrots caused high levels of carotene in the blood, leading to abnormalities such as infertility, amenorrhea, and anovulation.
Researchers suggest that this may be caused by carotene interfering with steroid synthesis. Clinicians have observed in six women who experienced menstrual abnormalities due to excessive carrot consumption that their ovaries were a bright yellow color, earning them the name "golden ovaries."
