1. Cold food: Crabs are cold, and generally can't be eaten with cold foods such as kelp, bitter gourd, white radish and watermelon to avoid symptoms such as indigestion, bloating, abdominal pain and loss of appetite.
2. Acidic food: Eating crabs with acidic foods such as grapes, tomatoes, apricots, beef and duck meat may affect the absorption of protein by human body, thus reducing the nutritional value of crabs.
3. Cold medicine: Eating crabs together with cold medicine such as Anka Huang Min Capsule and Ganmao Qingre Granule may affect the efficacy, and at the same time, the body's resistance is relatively low when catching a cold, so eating them together may easily cause allergic reactions.
