Health care function of eating five reds on Dragon Boat Festival

Apart from the legendary factors, these five foods are all seasonal delicacies in early summer, with rich nutrition and delicious taste.

1, lobster

Lobsters enter the "five reds" in the shortest time. It began to appear on the dining table of Nanjing people in the 1970s, gradually replacing "fried shrimp" and becoming the new favorite of "Five Red". The amino acid composition of lobster is better than that of meat. It contains 8 kinds of essential amino acids which are necessary for human body but cannot be synthesized or insufficient in the body. It is rich in fat-soluble vitamins, such as vitamin A, vitamin C and vitamin D. ..

Because the bacteria, parasites and heavy metals such as lead, mercury, manganese, chromium and arsenic contained in lobster are basically in the head, the head must be removed when processing or eating. It is also important to remove cheeks, claws and shrimp lines and scrub shrimp shells. Pay attention to high-temperature cooking, and the time should not be less than 20 minutes.

2. realgar wine

The custom of drinking realgar wine is related to killing five poisons. Ancient people thought realgar could restrain snakes, scorpions and other insects. Realgar wine is a kind of wine brewed by grinding realgar into powder. Realgar, as a traditional Chinese medicine, can be used as an antidote and insecticide, so the ancients thought that realgar could restrain the five poisons.

In fact, the main component of realgar is arsenic sulfide, which is the main raw material for extracting arsenic and a strong carcinogen. Even if taken in small doses, it will do harm to the liver. Therefore, drinking realgar wine is unscientific.

3. Duck eggs

Duck eggs with red oil are also one of the "five reds". Around Tomb-Sweeping Day, ordinary folk families began to pickle a batch of duck eggs, because at this time, "clear eggs are good for dinner". Duck eggs are preserved until the Dragon Boat Festival. They are moderately salty and just edible. The best salted duck egg red heart oil is a good product for calcium supplementation in summer.

Nanjing people not only like to eat hot rice with salted duck eggs at the dinner table, but also like to tie colorful threads and hang salted duck eggs on their children's chests or wrists.

4.roast duck

Duck meat is rich in 8 kinds of amino acids, unsaturated fatty acids and various nutrients necessary for human body. Each gram of duck meat contains linoleic acid 1.78 1 microgram and taurine 555 microgram, which is easy to digest and absorb, reduces blood lipid and blood viscosity, and has a preventive effect on diabetes and dermatosis caused by decreased immunity.

When eating roast duck, adding onion, garlic and cucumber strips can not only balance acid and alkali, but also vitamin C and dietary fiber in these foods can reduce cholesterol, improve fibrinolytic activity and help digestion.

5. purplish red

Amaranth is the most "senior" among the "five reds". During the Republic of China, Pan Zongding recorded in Jinling Years that Nanjing people used to eat amaranth on Dragon Boat Festival, which was said to avoid abdominal pain.
