Most types of fish are rich in high-quality protein, iodine, various vitamins and minerals. Such as vitamin D, vitamin B12, phosphorus, niacin and especially omega-3 fatty acids. However, each type of fish has its own nutritional differences, mainly in terms of fat content.

Although fish is so good, many people do not know how to eat it, eat it incorrectly or waste it. The China Association for Science and Technology (Headquartered in Beijing) said that there are 3 parts of the fish that bring many health and beauty benefits but few people know. Even when eating fish, many people throw these parts away.

Many people think that fish heads have little meat, many bones, so they are easy to choke on and contain a lot of dirt. In fact, the nutritional value of fish heads is very high, such as protein, calcium, phosphorus, iron, vitamin B1 and other nutrients.

Especially the heads of fatty fish and deep-sea fish are even more nutritious and good for health. They are rich in omega-3 unsaturated fatty acids and phospholipids. These are very good substances for brain development, preventing stroke, improving memory and preventing and treating Alzheimer's disease.
