What is the reason why China ancient sailing fleet didn't get scurvy?

When we were studying world history, we realized that Columbus left Spain for South America to travel around the Pacific Ocean. There were more than 200 people when he left. A few months later, there were only 30 people left, and most of the sailors died of scurvy. Until the middle of18th century, the voyage still led to the decline of a large number of seafarers. At that time, westerners still regarded this high decline rate as an irresistible price.

But there was no scurvy in Zheng He's fleet in Ming Dynasty. Why is this? Compared with western foods with high calorie and high egg white, such as big fish, big meat and cheese, China's ancient voyages were mixed with all kinds of meat and vegetables: besides meat dishes, we also carried a lot of pickles and pickles, and China people drank green tea, which also contained vitamins. Our unique dietary habits in the East suppressed the scurvy problem of Zheng He's fleet, while Columbus's fleet resigned itself to fate.

Besides carrying abundant food, we also have a racial talent of "growing vegetables". When Zheng He's fleet was idle, everyone was planting vegetables at sea, but they were actually sprouting bean sprouts. The fleet carried a lot of dried mung beans. When you want to eat, just add some water, and a lot of mung bean sprouts will grow in a day or two.

When it comes to the "national talent" of growing vegetables, we China people are full. In the younger generation, after our parents retired, as long as there is space and conditions, who hasn't planted vegetables? Land cannot be wasted. We should respond to Chairman Mao's call to "preserve honor and discard shame"

In Antarctica, lettuce is grown to rinse hot pot. In Tibet, vegetables are grown to open green meat. Even Sansha in Hainan has four vegetable greenhouses!

Going abroad for diplomacy, the embassy grows vegetables. Rwanda in Africa is poor in products, so the price is very expensive. So the people in the embassy are self-reliant and have no worries about food and clothing, and they grow vegetables in the embassy themselves.

Even the escaped peacekeeping tribes took time to grow vegetables. When I was building aid in Tanzania, I worked on projects during the day and grew vegetables at night.

There are also some immigrants who go abroad and grow all kinds of fresh vegetables in their own open spaces. Even Michelle, the wife of former US President Barack Obama, can't help but follow suit and open cabbage in the White House.

People in China like to grow vegetables and eat green vegetables. In today's rich material, meat has unconsciously become a condiment. Put a little when cooking, and finally there will be meat left after eating.
