Legumes
Legumes, such as beans, chickpeas, and lentils, are high in zinc, a mineral that aids in wound healing. In fact, a zinc shortage can be a significant cause of tissue damage. Soaking, boiling, and sprouting legumes before eating them may help with zinc absorption. One cup of kidney beans, chickpeas, or lentils contains 11%, 14%, or 20% of the daily value.
In addition to zinc, legumes are high in fiber, which softens and regulates feces to avoid fissures. One cup of beans contains around 11-16 grams of this vitamin. Although administering zinc topically to an anal fissure may help minimize discomfort and expedite recovery, see your doctor first.
