Clams eating notes:
1, gout patients should eat less or avoid eating. Clams belong to high purine food (purine content of 150~1000 mg/100g). Whether in acute or remission, gout patients should eat less or avoid eating this kind of food.
2, cooking clams should not put MSG. Shrimp, oysters, clams and other seafood, with its own natural food flavor, the addition of monosodium glutamate (MSG) will destroy its original freshness, play the opposite effect.
3, eat clams should be fully heated. Due to the cold nature of clams, some people with a cold stomach and spleen eaten easy to diarrhea and other symptoms, coupled with the heat of the day shellfish are more prone to death and deterioration, and therefore eat more to pay special attention to. To be on the safe side, try not to eat the black part of the viscera, eat to heat.
