Is it necessary to remove the black lines on the shrimp’s back?
Share on VnExpress, PSG. Dr. Nguyen Duy Thinh (Institute of Science and Technology, Hanoi University of Science and Technology) said that the black or white line on the back of the shrimp is the shrimp’s digestive tract containing the stomach and colon. Normally, in large shrimp, this black line is quite visible.
According to Associate Professor. Dr. Nguyen Duy Thinh, this shrimp thread is small and does not cause danger such as poisoning or severe diarrhea because through the processing process, the bacteria in the shrimp thread are all dead. However, this shrimp thread is both dirty and has no nutritional value, so when processing, you should remove it to make the dish more delicious and cleaner.
Especially for young children and people with weak intestines, removing shrimp veins before processing is extremely important to ensure the safety and hygiene possible.
In addition, the shrimp shell has no nutritional value. Young children may choke when eating it. You should discard it when processing shrimp.
Health benefits of shrimp
According to a post on the Vinmec International General Hospital website, shrimp brings a number of health benefits to users as follows:
Helps lose weight
Shrimp is low in carbs and calories but full of nutrients, so it is an ideal dish for people who need to lose weight. However, if you want to lose weight, you should only eat boiled or steamed shrimp, avoid fried dishes with a lot of oil or eat them with cream sauce.
Antioxidant
The antioxidants in shrimp are very good for your health and have the ability to protect and fight inflammation by preventing free radicals from damaging your cells.
Many studies show that the antioxidant astaxanthin in shrimp helps prevent wrinkle formation and reduces the harmful effects of sunlight, thereby slowing down the aging process. This substance also plays a role in strengthening the arteries, helping to reduce the risk of heart attack and some chronic diseases. Furthermore, astaxanthin is also beneficial for brain health, prevents memory loss and neurodegenerative diseases (such as Alzheimer’s), and increases good HDL cholesterol levels.
Many good substances prevent disease
The nutritional value of shrimp is also a rich source of the following substances:
- Iodine: Important mineral, essential for thyroid function and brain health.
- Selenium: The mineral helps reduce inflammation and promote heart health, and research even shows that this mineral also prevents certain types of cancer.
- Omega-6 and omega-3 fatty acids provide many health benefits.
