Eat the whole egg
Whether it is eggs, duck eggs or pigeon eggs, children are encouraged to eat whole eggs. Eggs are not only an excellent source of protein, but also choline released from the absorption of lecithin in egg yolk can be synthesized into acetylcholine, which can significantly improve children's memory. In addition, the content of iron and phosphorus in egg yolk is high, which is also beneficial to children's brain development.
Edible method of walnut kernel
Walnut kernel can nourish blood and produce marrow, strengthen kidney and brain, and is a good product to enhance memory and understanding. Parents can stew walnut porridge for their children, or mix mashed walnut kernels with black sesame seeds to make pies or buns for their children to eat. Walnut kernel contains more oil and is not easy to digest. Generally, it is enough for children aged 3-6 to eat 3-4 large walnuts every day.
