My good friend who lives in a rural area knows a lot about sweet potatoes and potatoes. Especially in autumn and winter, burn the leaves into ashes, then pick two sweet potatoes and a few potatoes and bury them in the ashes. You will soon have fragrant roasted sweet potatoes and roasted corns, which you can even eat when you go home. No less.

It is very obvious that sweet potatoes and potatoes will become staple foods, but the fact at this stage is that potatoes, wheat, rice, and corn are collectively called the "four major staple foods" of our country, but sweet potatoes are not selected. It stands to reason that sweet potatoes are rich in nutritional value, contain sweetness, and are rich in dietary fiber. They should also become one of the staple foods, right?

Some people joked that eating too many sweet potatoes would cause abdominal distension and constant stinky farts, which would seriously affect a person's image, so sweet potatoes cannot become a staple food. Just laugh at this. Sweet potatoes often fail to become a staple food, and there are reasons of their own.

1. Today’s sweet potatoes are improved sweet potatoes

You will find that after the sweet potatoes are steamed and roasted, the core of the sweet potatoes will ooze "honey", and the sweet potatoes with built-in sweetness are deeply loved. It is favored by young people, especially sweet potatoes that have a toffee flavor when baked. The price is high, but young people can accept it and eat it as a snack for a few days. But if you eat these sweet sweet potatoes every day, you will soon be unable to eat them anymore.

The sweet potatoes of the past were not that sweet. People of the previous generation knew that the sweet potatoes they used to fill their stomachs were white and had no sweetness. They were boiled before eating, and occasionally dipped in condiments. . As long as the food crops are plentiful that year, sweet potatoes will be used to raise pigs.

2. Sweet potatoes are perishable

Compared with potatoes, the shelf life of sweet potatoes is too short. Potatoes can still be stored in the basement or in a cool, dry place for a few weeks, but sweet potatoes are perishable and are basically not a guarantee of survival in the south. Therefore, sweet potatoes in the south are also made into sweet potato vermicelli and sweet potato skins.

3. Sweet potatoes are not suitable for people with weak stomachs

As mentioned above, eating sweet potatoes often will cause constant farting. For healthy people, this is just the case, which will affect the taste and image. That’s all. But for people with a bad stomach, eating sweet potatoes often will cause bloating, gastric juices, and the more you eat, the more uncomfortable you will feel. Therefore, people with a bad stomach do not need to eat sweet potatoes.

4. The production volume of sweet potatoes is not as good as that of potatoes.

Compared with potatoes, which have extremely strong survival ability and extremely fast production speed, the production volume of sweet potatoes is obviously not as good as that of potatoes. It can only be grown one season a year, and not all areas can be planted. In areas with higher altitudes and drier climates, sweet potatoes are not suitable for planting. They are not as strong as potatoes. They can be grown 2-3 seasons a year, and the planting range is also wide.

5. There are not as many cooking methods for sweet potatoes as there are for potatoes.

From a eater’s perspective, it is obvious that there are not as many cooking methods for sweet potatoes as there are for potatoes. When it comes to sweet potatoes, everyone will think of roasted sweet potatoes, steamed sweet potatoes, shredded sweet potatoes, etc. When it comes to potatoes, they can be sweet, salty, Chinese-style, European-style, as a meal, as a snack, and can be made in various ways. And the fragrant potatoes will appear immediately, and the cooking is diverse and delicious.

In this comparison, sweet potatoes are absolutely incomparable to potatoes. It is not unreasonable to choose to include potatoes as one of the "four major staple foods" in our country. However, this does not mean that sweet potatoes are not suitable for daily consumption. Sweet potatoes, which are nutritious and fragrant, are now quite good as a substitute for bean noodles.

But it is better to eat less roasted sweet potatoes. If you want to lose weight, replace the carbohydrate bean noodles with boiled sweet potatoes or steamed sweet potatoes to achieve the weight loss effect.
