In nutrition and food safety theory, there is no “food incompatibility”, generally as long as there is no allergy, sweet potatoes and eggs can be eaten together, and will not adversely affect the health of the body. Sweet potato carbohydrate content is high, such as every 100g sweet potato contains about 24.7g carbohydrates, can provide the body with about 446KJ of energy; while the egg protein, fat and other content is high, such as every 100g of eggs contain about 13.3g protein, 8.8g fat, the two with the consumption, can play a complementary role. It should be noted that some people may be allergic to eggs, they should avoid eating eggs, so as not to induce allergies. The general public can eat according to their own preferences, but not blindly eat more, so as not to cause gastrointestinal discomfort.
