Seafood and Aquatic products—real cod
The common "real cod" in the market are Atlantic cod, Pacific cod or Mingtai fish, and "silver cod" are psilocybin or canine tooth fish.
"Real cod" is high in protein and low in fat, and has a low risk of mercury, but the content of EPA and DHA is very general, so it doesn't have to be regarded as a nutritional product.
Psilocybin has a high content of EPA and DHA and a good taste, but there is a certain risk of mercury accumulation.Taking into account nutrition and health, give your child at most once a week.
The so-called "deep-sea cod steak" may use a fish called fine-scaled strong cod, which has more water and less protein and low nutritional value.
