Foods that tend to cause miscarriage include bitter melon, kelp, hawthorn, cinnamon, crab and turtle. Although bitter melon has the function of clearing heat and detoxifying, it contains quinine, which tends to cause uterine contractions. Kelp has the function of resolving blood stasis and dispersing nodules, which can easily cause bleeding and miscarriage when consumed in early pregnancy. Hawthorn can stimulate the uterus to cause contractions and lead to miscarriage. Cinnamon is a hot food, which also tends to cause miscarriage. Crab and turtle are cold foods that have the function of activating blood stasis, which can easily cause miscarriage in the early stage of embryo. Therefore, the above foods should be avoided as much as possible, and do not eat spicy and stimulating foods. You can eat more high-quality protein foods, such as milk, eggs, chicken, etc., as well as fresh vegetables and fruits.
