Sweet potatoes and potatoes are both staple crops, why are sweet potatoes more popular than potatoes

In addition to nutrition, we often watch the natural scenery of Northern Europe on TV and think it is beautiful. But the Nordic region is very cold, the grain production is very low, and their staple food is potatoes. Moreover, the variety of potato recipes can be said to be eye-opening.

The Nordic people eat potatoes as their staple food and do not choose sweet potatoes, indicating that potatoes have the advantages that sweet potatoes do not have. The growing environment is a problem, the temperature is very cold in northern Europe, but the potatoes can grow, indicating that the potatoes are very adaptable. There is no such sweet potato.

For the production of potatoes to become the main production, it must pass through the gate. The yield of sweet potatoes is about 2,000 catties per acre, but the combat effectiveness of potatoes is simply 10,000. Potatoes can yield twice as much as sweet potatoes.

It is the storage of potatoes. Potatoes are stored for a longer time than sweet potatoes. In the past, there was a sweet potato warehouse in my hometown.

Because sweet potatoes cannot be stored. But potatoes can last for a long time. Instead of choosing sweet potatoes as a staple food, it is better to choose potato staple shoes, which also makes a big difference.

For example, the differences between the two crops can be summarized in the following three points, such as the planting method and popularity, the nutrient content of the tuber, the convenience of storage, and the way of eating. The planting range of potatoes is very wide, the planting area is very large, the planting method and harvest are simpler and labor-saving than sweet potatoes, and the planting range of potatoes can be planted from the south of our country, Guangdong, Guangxi to Heilongjiang, Liaoning, Xinjiang in the northwest, not to mention other places.

Sweet potatoes are usually stored in basements in rural areas, and this is because sweet potatoes are more demanding to the environment, so they are left at a temperature of around 4 degrees for a longer period of time. Potatoes can generally be stored at room temperature and do not require too strict storage conditions, so potatoes have great advantages over sweet potatoes in terms of planting range and storage conditions. Sweet potatoes and potatoes are grown in the same way, but potatoes are easier to grow and harvest.

Sweet potatoes require seedlings, planting, water, intermediate management, transplanting, etc., and when harvesting, they need to be planted and discovered. But potatoes are tuber grown, which is much easier, and later management and harvesting are more mechanized, much easier than growing sweet potatoes.

There are many places where you can grow two crops of potatoes per year, but it is difficult to grow sweet potatoes. In this way, the annual yield of potatoes is generally larger than that of sweet potatoes, so the advantages of planting methods and yields are another reason to include potatoes in the staple food. Sweet potato stalks contain a lot of starch but lack the corresponding nutrients.

For example, according to the relevant demonstration materials of the food nutrient content inspection agency, the protein and carbohydrates of sweet potatoes and potatoes of the same quality are very different, and the content of other nutrients in sweet potatoes is not as good as that of potatoes.

Because the yield of sweet potatoes is relatively high, planting a sweet potato seedling can produce a lot of sweet potatoes.

Because the yield of sweet potatoes is relatively high, many farmers plant sweet potatoes to feed pigs, compared to the yield of potatoes is not as high as that of sweet potatoes, and sweet potatoes can be eaten raw, but potatoes cannot be eaten raw.

Because sweet potatoes have a higher yield than potatoes, and because sweet potatoes are more resistant to disease than potatoes, easier to grow and store, and require a lot of sweet potatoes to make starch, sweet potatoes are more popular than potatoes.

Hello dear, what is the fundamental reason for the advantages of sweet potatoes ? Answer: 1. Rich in nutritional value, sweet sweet potato is also known as sweet potato, which is rich in carbohydrates and protein, and is very nutritious.

It also contains a variety of minerals, calcium, iron, phosphorus, etc., as well as a variety of vitamins, which contains more nutrients than commonly eaten rice, and has a sweet taste suitable for all ages. 2. Sweet potatoes can moisten the intestines and laxative, and sweet potatoes themselves are also a kind of coarse grains, which are rich in dietary fiber. Eating whole grains is a good choice for obese people and people with chronic diseases, but be careful of the sugar in sweet potatoes.

3. Sweet potatoes can replace staple food** and because dietary fiber itself cannot be digested, it can be of little help to ** people. Because the presence of dietary fiber can provide a stronger sense of satiety, so that we will not feel hungry easily, and many people will be full quickly after eating a sweet potato, which actually helps us**. And it is also rich in carbohydrates to maintain normal calorie supply, containing relatively little fat of filial piety, you can choose an appropriate amount of sweet potatoes in daily life to replace the staple food.

This is because sweet potatoes have a very high starch content and are generally difficult to digest, so sweet potatoes do not enter the four major staple grains.

This is because sweet potatoes have certain limitations and cannot be eaten with some foods, so sweet potatoes cannot be the four major staple foods.

Because the red cave manuscript potato is not easy to store, long-term storage will lead to mold and rot, and the starch in the sweet potato is too pure and much more wild, eating too much will easily lead to gastrointestinal indigestion. Do shouting.

Sweet potato as a very popular crop, in the historical development of our country also has an indispensable role in recommending, in the Anti-Japanese War was used as a staple food dry food was transported to the front in large quantities, sweet potato is rich in nutritional value, fiber content is a lot, often eat not only can supplement the needs of the human body, but also play a role in human health care.

Sweet potatoes are rich in dietary fiber, which can clean up intestinal waste, collect toxins and wastes, and excrete them from the body, vitamins can also create new cells in the intestines and promote metabolism. It can soften blood vessels, slow down aging, and can also help people with colds to defend against viruses.

The first is eggs, sweet potatoes and eggs are easy to cause indigestion, so that the protein in eggs and the vitamins of sweet potatoes can not be absorbed by the stomach, resulting in a great waste of resources, eating is equal to eating in vain, so these two foods must be eaten after an hour, do not eat together.

And then there's persimmons. Sweet potatoes and persimmons are easy to cause diarrhea when eaten together, because the pectin in persimmons can easily react with gastric acid and become a sticky state, at this time it is difficult to absorb the nutrients of sweet potatoes, and the pectin content of sweet potatoes is also very rich, so the two are mixed together and cannot be digested, and finally only excreted through diarrhea.

There is also a kind of wine, the main content of wine is alcohol, especially some pure grain fired liquor, and sweet potatoes will be eaten together to find the phenomenon of heartburn and nausea, this is the phenomenon of food restraint, after finding discomfort immediately stop drinking or eating sweet potatoes.

Don't eat too much: If you eat too much sweet potatoes at one time, it is easy to cause bloating, heartburn, nausea and vomiting. This is because sweet potatoes produce a gas that is difficult to digest, and stomach acid will increase a lot, so people who usually have a bad stomach must eat less.

Do not eat it raw: If you find brown spots on the skin of sweet potatoes, or if they have begun to sprout, do not eat them, which can easily lead to food poisoning.

1.Prevention of constipation: Sweet potatoes are rich in dietary fiber, of which white sweet potatoes are rich in dietary fiber equivalent to about 10 times that of rice noodles. It can help accelerate the peristalsis of the intestines and help to defecate, that is, it can relieve constipation.

2.**: Sweet potatoes are very good** ingredients, the same weight of sweet potatoes and rice, the calories are only one-third of rice, is a low-calorie, low-fat food. And the best thing is that sweet potatoes prevent sugars from being converted into fat, which has a good ** effect.

3.Lowering blood pressure: Sweet potatoes are also a very good blood pressure lowering artifact, because sweet potatoes are also rich in potassium, which can affect blood pressure!

Know that you can't eat with sweeter foods, crabs, persimmons, tomatoes, pumpkin, bananas, these foods can easily cause bloating.

Know. Sweet potatoes should not be eaten with persimmons, otherwise there is a high risk of diarrhea and a lot of stomach acid. Do not eat it with alcohol, otherwise you will have heartburn and nausea, so don't eat too much at one time, otherwise you will have bloating.

It cannot be eaten with sweets, persimmons, crabs, tomatoes, or pumpkins.

I know that it can't be eaten with sweets, chicken, persimmons, seafood, crabs, these foods because it can cause diarrhea, bloating.

Relatively speaking, the yield of potatoes is higher, the environmental requirements of potatoes are relatively low, and the growth cycle is shorter than that of sweet potatoes, which is also related to people's dietary preferences.

Some people joked that it was because eating too many sweet potatoes would cause flatulence and keep farting, which affected a person's image, so sweet potatoes could not become the staple food. It's good to laugh at this statement, and there are other reasons why sweet potatoes can't become a staple food.

The people of the older generation know that the sweet potatoes they use to satisfy their stomachs are white-hearted, without any sweetness, boiled in water and then eaten, and occasionally dipped in condiments. As long as there are abundant grain crops in that year, sweet potatoes are used to raise pigs.

1. Sweet potato vine is not turned over, potato seedlings go to the top, 2. Skillfully chase the expansion fertilizer, increase yield and improve quality, 3. Spray foliar fertilizer, increase yield and prevent decay, the soil can not be too arid, drought can easily lead to stunted development of potato pieces.

The best thing to do is to fertilize every other month, so that the nutrients are enough for high yields.
