What are you going to do when you grow up?", roasted sweet potato". This sentence can be said to be all the rage on the Internet, and it has also set off a wave of people's love for roasted sweet potatoes, and for a while, roasted sweet potatoes are very popular.
Especially now that winter is coming, roasted sweet potatoes are a very typical winter delicacy. But what many people don't know is that sweet potatoes are controversial, and many people are puzzled about a question.
Why are potatoes a staple food for people to eat, but sweet potatoes are not recommended?Sweet potatoes are worse than potatoes againAfter all, sweet potatoes used to be a very important crop in our country. Next, let's talk about this question.
It is important to know that sweet potatoes are different from potatoes, which are tropical crops that are susceptible to heat and drought, especially those with higher requirements for the environment and soil, while potatoes are able to adapt to more environmental and climatic conditions.
It can be grown in alpine regions, high altitude areas and barren land, so it is not limited by natural conditions and can be widely cultivated in many places to meet people's demand for staple foods.
In northern China, potatoes have become the main food crop due to their favorable climatic conditions for growing potatoes. The southern region is more suitable for growing sweet potatoes.
Secondly, in the past, farmers in our country mainly produced sweet potatoes for energy and nutrition, rather than treating them as the main food crop. Potatoes, on the other hand, have gradually become one of the main food crops due to their high starch and protein content.
It is worth mentioning the yield of potatoes, which is relatively high, and can obtain more grain income per unit area. According to statistics, potatoes are produced more than other staple crops such as wheat and rice.
Therefore, it is important to address the issues of food security and population growth. Moreover, potatoes can be made into a variety of foods, such as fried shredded potatoes, mashed potatoes, hash browns, etc., providing people with a variety of food choices.
Potatoes can be cooked according to their hobbies, and at the same time, potatoes can also be processed into starch, potato flour and potato chips, which have a wide market demand.
For most merchants, potatoes are undoubtedly a good choice, because potatoes have a short growth cycle, a more concentrated harvest season, relatively low planting costs, and are relatively stable.
This makes potatoes economically viable and able to meet the food needs of the broad masses of the people. Therefore, from the perspective of these aspects, it is not unreasonable that potatoes can develop into one of the main grains in China.
In the past few decades, the development of sweet potatoes in our country has been relatively slow due to the country's key support and priority development of food crops such as rice, wheat and corn.
In addition, sweet potatoes have some shortcomings compared to potatoes. First of all, the storage and transportation conditions of sweet potatoes are relatively poor compared to potatoes, generally speaking, sweet potatoes can be stored for a relatively short time, and the requirements for the environment will be relatively high.
Secondly, sweet potatoes can generally be boiled in sugar water, steamed directly, or roasted, and compared with potatoes, sweet potatoes need to be digested for a longer time during eating, so it is difficult to meet people's needs for fast energy.
Due to the high fiber content of sweet potatoes, it is relatively difficult for people with weak digestive systems such as children and the elderly, which is not conducive to the absorption of nutrients, and these factors have caused certain limitations to the development of sweet potatoes as a staple food.
In particular, some sweet potatoes can easily block the throat, which is a very dangerous thing for the elderly and children, and it can lead to suffocation if you are not careful.
However, in recent years, with the gradual increase of people's health awareness, sweet potatoes have been recognized and accepted by more and more people as a nutritious food, and their status as a staple food has gradually improved.
Because the promotion of cereals in traditional Chinese medicine is very in place, everyone realizes that they usually need to consume more cereals to maintain some of the energy supplements that the body needs.
Sweet potatoes are also used as a type of whole grains, so many people now buy sweet potatoes to prepare at home, wash a few when they want to eat them, or develop some new edible flavors.
At the same time, with the continuous improvement of technology and planting techniques, the yield and quality of sweet potatoes are also increasing and improving, which provides more favorable conditions for their further development as a staple food.
So now you understand why sweet potatoes can't be used as a staple food compared to potatoes?As a nutritious food, sweet potatoes have broad prospects for development in China and will be liked by more people in the future.
However, its different characteristics and defects from potatoes make it still have room for development and challenges. Only through continuous research and development and innovation, optimizing its quality and taste, and solving the problems of storage and transportation, can we finally realize the staple food of sweet potatoes.
