The only gluttony you have not thought about, cold skin, cold noodles and other "cold food" nutritional value is actually very low, often a meal only eat cold skin, may make you "malnutrition".

The "nutritional truth" about a bowl of cold skin.

Cool skin with a refreshing appearance and smooth texture.The main raw materials are various types of grain flour and starch..

The gluten is washed during the cold skin making process, and gluten protein makes up the majority of wheat protein. Also, because of the addition of alkali or puffy ashes, the gluten is washed with a lot of water, which loses most of the soluble B vitamins and potassium. .

The protein content of cold skin eaten with gluten is about 4.4 grams per 100 grams.

Eating half a kilogram of cold skin, you can only get 10 grams of protein, although cold skin is usually accompanied by some gluten, but the quality of gluten protein is relatively low, and there is a big gap between the ratio of essential amino acids and the human body needs.

A normal adult needs about 60 grams of protein per day, with an average of 20 grams per meal.

And eat into the mouth of the cold skin, probably only "calories". From a nutritional point of view, the cold skin as a staple food, as opposed to directly eat white rice.

The "cool" food nutrition is similar.

In addition to cold skin, summer can be coveted for a variety of cold noodles and powders, none of which are actually too high in nutritional value.

Cold noodles

In terms of nutritional value, cold noodle snacks are the least nutritious.Noodles, Noodle Skin, Noodle FishIt also includes, after drying, theVermicelli, Vermicellietc.

Because starch is processed to remove most of the protein, the process of washing starch, and lost most of the soluble B vitamins and minerals such as potassium.The rest is almost pure starch..

The starch is turned into starch paste by adding water, and then cooled into jelly, the product is cold noodles, noodle skin, noodle fish, after drying can be made into noodles, vermicelli, etc. According to the data listed in the Chinese Food Ingredient Table, 11.3 grams of starch per 100 grams of well-seasoned cold noodles contain 11.3 grams of starch.

According to the data listed in the Chinese Food Ingredient Table, per 100 grams of seasoned cold noodles, it contains 11.3 grams of starch, but only 1.5 grams of starch per 100 grams of seasoned cold noodles. It contains 0.3 grams of protein.

A regular meal should contain at least 20 grams of protein, and you feel pretty full after eating half a pound of cold powder, which can fall far short of the amount of protein your body needs.

At the same time, the water-soluble vitamins and minerals in the cold powder is almost eliminated, its nutritional value is negligible. Instead, the seasoning added peanut butter, marijuana juice, containing many nutrients.

It can be said that eating noodles is like eating pure starch gelatinous jelly, experiencing the smooth taste, and the spicy flavor in the seasoning, or masa flavor.

From a nutritional point of view, eating noodles is as good as eating sugar as rice.

Cold noodles

100 grams of cold noodles contain 4.8% protein, a little higher than cold skin.

However, the noodles need to be cooked in a lot of water, and the soluble vitamins and minerals will dissolve in the water during the cooking process, and if the noodles are cooled several times, the content will be even lower.

In order to make the noodles stronger, alkali is often added, which "kills" the B vitamins in the noodles.

Korean-style noodles are made with not only flour, but also starch, which has a lower nutritional value than ordinary noodles.

The bean noodles traditionally made in the North are much better than the Korean style noodles.. Because beans contain twice as much protein as flour, have more vitamins and minerals, and the bean starch has a stronger texture.

Even if the mixed bean noodles are boiled and eaten cold, they still have more nutritional value than regular cold noodles.

Rice Tofu

There is no need to wash gluten in rice tofu, it is just ground up with rice, boiled to a paste with alkali, and then cooled and frozen. However, because of the addition of alkali to boil, the vitamins B1 and B2 in the rice are also almost completely destroyed by the alkali.

The alkali causes the trace amounts of flavonoid substances in the grain to change from a colorless state to yellow, which is why rice tofu is yellow in color. The protein content is similar to that of thick rice porridge, only less than 2%.

Sausage noodles

Sausage flour is not much better, with a protein content of only 1.3%.

It is made of glutinous rice flour paste after steaming, but in order to achieve the smooth effect, which also add clarified flour and starch, reduce the protein content and improve transparency, the main contents of which are still starch and water.

In the time of eating sausage noodles usually have to pack in some BBQ pork, shrimp and other protein-rich ingredients, to a certain extent, to make up for the shortcomings of a serious lack of protein, but the lack of B vitamins and a variety of minerals is still not resolved.
