Underweight
Ginger is a rich source of fiber which regulates the pH balance in the stomach, triggers the secretion of digestive enzymes, and supports the fat burning process in the body. Yet, it is not recommended for underweight people as it can cause hair loss, loss of muscle mass, appetite loss, and weight loss, and even an irregular period in women.
Pregnancy
Ginger strengthens the muscles and helps digestion, but it should be avoided in the case of pregnancy as it can cause uterine contractions and premature labor.
Some women use it to reduce their morning sickness, but you should stay away from it, especially during the last trimester of the pregnancy.
Ginger also interferes with the absorption of iron and fat-soluble vitamins in the body. Therefore, you should avoid ginger in the case of these 4 conditions, and consume cayenne pepper or paprika instead.
