Shellfish seafood is in the breeding period in spring and summer, and its meat is crisp and tasteless. However, when winter enters the dormant period, the activity of shellfish decreases and the consumption of nutrients decreases, so it is very suitable for eating. Shellfish also has the unique function of inhibiting liver cholesterol synthesis and accelerating cholesterol excretion, which helps to reduce cholesterol in the body and is suitable for people with high cholesterol.
