Eating one or two eggs a day is good for health. But if the digestive system is abnormal, such as stomachache and diarrhea, don't eat it, because eggs contain high protein and are not easy to digest. You can eat egg yolk alone because it is the easiest to digest and absorb. Adding a proper amount of clarified quicklime water when steaming eggs can promote the transformation of cholesterol into vitamin D and promote the absorption of calcium.
