White Potato, Sweet Potato, Purple Potato, Who Has Better Nutrition?

Each has its own advantages, if it is **, purple sweet potato is the first choice, because purple sweet potato is relatively low in starch and rich in fiber.

In fact, strictly speaking, there is not a big difference between the three.

I think purple potatoes are more nutritious, and they are relatively expensive.

I don't think there's much difference in nutrients, it's mainly up to your preference.

This should be a little more nutritious purple potato, so people like to eat purple potato.

I think it should be that the nutritional value of purple potatoes is relatively high, and purple potatoes contain more nutrients.

If you want to make a comparison, the nutrient content of purple potatoes is a little more, and the ** of purple potatoes is a little higher than others.

In general, sweet potatoes have a higher nutritional value than several others.

I think purple potatoes are more nutritious, and sweet potatoes are a bit high in calories.

White potato, sweet potato, purple potato, which has higher nutritional value? This question I will start withChinese and Western NutritionFirst, from the perspective of Western nutrition, all three potatoes are the same, depending on personal preference; why?Because, they both belong to one of the three major nutrients in carbohydratesPotatoes

In our body, brain tissue consumes more energy, and under normal circumstances, the energy consumed by brain tissue comes from the aerobic oxidation of carbohydrates; So,Brain tissue is very sensitive to hypoxia.

Busy work and stressful lives make us very dependent on blood sugar levelsLow blood sugar levels are uncomfortable

Therefore, the Chinese Nutrition Society has based on the current residency of our countryActual intake of dietary carbohydratesand FAO and WHO recommendations:

Acceptable range of macronutrients; Among them, potatoes can be eaten every day50-100 grams

Second, from the perspective of traditional Chinese medicine nutritionIt varies from person to person, from place to place, from time to time1. White potatoesPeople in the north and south are suitable for autumn and winter, and the white color enters the lungs, which will be relatively strong in nourishing the lungs; On the contraryIf there is a lot of phlegm, you should eat less;

2. Sweet potatoPeople in the north and south are suitable for autumn and winter to eat, red into the heart, relatively speaking, the effect of nourishing the heart and blood is stronger than that of white potatoes; On the contrary, those who are overheated should eat less;

3. Purple sweet potatoIn ancient times, there was no way, and there was no way to judge from the attribution of the 5 lines, and we could also eat a stubble, right?

As the saying goes", ".There is no beauty or evil in things, and if it is excessive, it will be a disasterChinese and Western nutrition have a common principle about potatoesIt's the quantityAdults eat 50-100 grams per dayIt is better to eat it at noon.

At the same time, it is highlighted in the nutrition of traditional Chinese medicinePeople with a bad spleen and stomach and diabetics,

I think the nutritional value of purple potatoes is higher, purple potatoes contain ingredients that sweet potatoes and white potatoes do not have, such as anthocyanins, which can protect the liver, have antioxidant effects, and can also prevent some cardiovascular diseases, and are also good for the stomach and are easy to absorb.

Purple potato, because purple sweet potato is very nutritious, and purple sweet potato can also make people solve constipation, and purple sweet potato is a little sweeter and more delicious than others.

The nutritional value is about the same, because they all belong to the same species, but the way they grow and look different

Overall, the nutritional value is about the same. All belong to the sweet potato family. It's just that different varieties belong to different places, and there are some differences and differences in taste.

Sweet potatoes and purple potatoes have similar nutritional elements: in addition to starch, soluble sugar, vitamins and amino acids, there are proteins, fats, dietary fibers, and minerals such as calcium and iron. Purple potatoes basically contain all the nutrients of sweet potatoes, rich in protein, dietary fiber, vitamins and trace elements.

After cultivating purple potatoes in Japan, they deliberately compared the differences between purple potatoes and ordinary sweet potatoes, and found that the lysine, copper, manganese, potassium, and zinc in purple potatoes were 3-5 times that of ordinary sweet potatoes.

Purple potato anthocyanins can significantly increase the content of bifidobacteria, lactic acid bacteria and enterococci in vitro experiments, and it is speculated that the consumption of purple potatoes rich in anthocyanins has benefits for the intestinal microenvironment and human health, which is also beneficial for the prevention of bowel cancer. As for whether it can achieve the effect of sweet potatoes on preventing constipation, maintaining the elasticity of blood vessels and preventing atherosclerosis. Compared to rice, the content of vitamin B1 and B2 is 6 times and 3 times higher than that of rice, respectively.

In particular, sweet potatoes are rich in lysine, while rice and flour are precisely lacking in lysine.

There are 8 kinds of vitamins such as vitamin A, B, and C, and more than 10 kinds of natural mineral elements that are necessary for the human body to resist fatigue and replenish blood, such as phosphorus and iron. Like sweet potatoes, purple potatoes are also rich in fiber, which can promote detoxification, improve the digestive tract environment, and prevent gastrointestinal diseases. It helps to defecate, cleans the digestive tract, shortens the retention time of toxic substances in food in the intestines, reduces the concentration of intestinal carcinogens, and prevents hemorrhoids and colorectal cancer.

At the same time, fiber can absorb a part of glucose, so that the amount of sugar in the blood is reduced, which helps to prevent diabetes.

It tastes drier and has a lighter sweetness. Because there is a lot of starch and low sugar content, the taste is not so sweet, and it is not very fragrant when baked, so it is not suitable for roasting and eating. Overall, the health benefits of white-fleshed sweet potatoes are less pronounced than those of other coloured varieties.

Sweet potatoes are rich in carotene, and although their functions are different, anthocyanins have better antioxidant effects. Secondly, purple potatoes are higher in minerals and dietary fiber than sweet potatoes, which is more conducive to delaying postprandial blood sugar. Of course, the water content of purple potatoes is relatively lower than that of sweet potatoes, so they taste sand and soft.

Purple sweet potato has high nutritional value. The content of selenium in purple potatoes is higher than that of sweet potatoes, and the anthocyanin content of purple potatoes is relatively high, which is generally not found in sweet potatoes, both of which are beneficial nutrients to the human body.

The nutritional value of purple potatoes is higher, the ** of purple potatoes is more expensive, and there are few purple potatoes on the market, and the sugar content is not very high, and a lot of trace elements can also be supplemented.

From the perspective of nutritional value, purple potatoes are higher in composition and more nutritious, which is very suitable for young children and women.

White potatoes and sweet potatoes are a common food that can also be called sweet potatoes, but they are different in color. For example, white potatoes and sweet potatoes are only different in taste and color, and sweet potatoes of red and yellow heart varieties are sweeter and suitable for roasting. The sweet potato with white heart is high in starch, so it will taste drier and is more suitable for boiling.

Sweet potatoes have elements such as protein, starch and vitamins, and are also rich in trace elements, which have anti-cancer, disease prevention and other effects. Sweet potatoes and purple potatoes are both root foods with rich nutritional value. From the perspective of nutrition, the nutritional value of purple potatoes is higher than that of sweet potatoes, because purple potatoes contain a large amount of selenium and anthocyanins, which can not only enhance the body's immunity, play an anti-cancer role, but also play an antioxidant role, which can prevent the body from aging.

To a certain extent, it can also promote metabolism, reduce blood pressure and blood lipids, and the effect of health care is higher than that of sweet potatoes.

The nutritional value of purple potatoes is a little higher, because the starch content in white potatoes and sweet potatoes will be a little more, and the nutrients in purple potatoes mainly include vitamins, proteins, and trace elements.

I think the nutritional value of purple potatoes is higher, because purple potatoes are rich in cyanins, and the polyphenols and zinc in them are higher than those in sweet potatoes and white potatoes, and the anti-cancer substances are also very strong, and the carotene in them is also very rich.

Purple potatoes are more nutritious.

Compared with sweet potatoes, purple potatoes have a higher nutritional value, because purple potatoes, an important nutrient of sweet potatoes, are also included. In addition, purple potatoes also contain a nutrient that sweet potatoes do not have, namely anthocyanins. The unique color of purple sweet potato is ** anthocyanins, which are also natural free radical scavengers, and their ability to scavenge free radicals is much greater than that of vitamins C and E.

But generally speaking, it is enough to eat sweet potatoes at home, and people in need can buy some purple potatoes to eat. However, whether it is sweet potatoes or purple potatoes, because the starch content is not low, they cannot be eaten more.
