Parts of shrimp you should not eat

Shrimp is rich in nutrients such as protein, calcium, omega 3, most concentrated in shrimp meat. For people with poor health who need to supplement calcium and protein, shrimp is the top choice.

Associate Professor, Dr. Nguyen Duy Thinh, Institute of Food Technology, Hanoi University of Science and Technology, said that shrimp is nutritious but some parts of it should not be eaten much.

Bark

The truth is that there is little or no calcium in shrimp shells. Shrimp shells are hard because their main component is chitin, a polymer that forms the shell of most crustaceans. The main source of calcium in shrimp is from shrimp meat.

In addition, the shells of some shrimp species are relatively difficult to digest, absolutely do not give them to children because they can easily cause choking.

Head

The head is the part that contains shrimp waste and accumulates a lot of heavy metals such as arsenic. For pregnant women, the toxicity of heavy metal arsenic is often very strong, eating a lot can lead to fetal malformations or miscarriage. Large shrimp need to be processed cleanly, removing the head to ensure safety.

When buying shrimp, you need to observe the head. If the shrimp head turns black, it is likely contaminated with metal, toxic substances, and parasites.

Black line on the back of shrimp

The black or white line on the back of a shrimp is also known as the shrimp thread. This is the shrimp's digestive tract containing the stomach and colon. This line is usually only visible in large shrimp.

Eating shrimp veins is not harmful to health, because the bacteria in the shrimp veins are killed at high temperatures when cooking. However, you should remove the shrimp veins to make the dish cleaner and more secure.

Notes when eating shrimp

Shrimp should be steamed or boiled to limit infection with worms and parasites that cause poisoning.

Women who have just given birth should limit their shrimp intake because it can cause indigestion or keloid scars. Children should not eat shrimp shells because they can easily choke or injure their throats.

People with coughs, allergies, pink eye, and asthma should also limit eating shrimp.

In addition, shrimp should not be processed with vegetables, tubers, and fruits rich in vitamin C. The reason is that when vitamin C meets the toxins present in shrimp, it will release toxins leading to food poisoning.
