Dear, who knows that those foods are sugar free and protein free, to be detailed!!

Since LZ is not a joke, you have to make the problem clear, do you want to have nothing at all, or do you mean that the sugar and protein content are low?

If it's nothing, then I'm going to popularize science:

All living things are made up of proteins, sugars, lipids, nucleic acids, water, inorganic salts, etc.

Among them, the highest content is protein, accounting for 7-10% of the fresh weight and more than 50% of the dry weight.

So if the landlord asks for foods that do not contain sugar and protein, then it can only be selected from the following foods:

1. Oil (grease).

2. Water. 3. Salt (all kinds of inorganic salts).

4. Some food additives (synthetic, without sugar and protein).

Sugar-free foods are almost non-existent. I only think of some that are low in sugar and low in protein.

1. Low sugar: peanuts, cashew nuts, mung beans, soybeans, strawberries, apples, pears, oranges, peaches, tomatoes, carrots, xylitol; 2. Low protein Grains and other proteins and fats are relatively small, if you eat more porridge, rice, steamed buns, vegetables, fruits, this contains less protein, oil, B6, don't eat meat, stir-fry less oil (you can use sesame oil to mix vegetables).

The same does not contain it, it is missing, neither of the two do it, drink water.

The cellulose in vegetables is a polysaccharide, which is a type of sugar, the fructose in fruits is also a type of sugar, and rice and pasta are starch and a type of sugar, which are all protein-free.

Nothing sweet, like starch.

Sugar-free foods mainly include: eggs, fish, meat, seafood and other animal foods, sugar-free vegetables: bamboo shoots, onions, bean sprouts, cabbage, mushrooms, soy products, fungus, sea vegetables, peppers and other vegetables do not contain sugar or low sugar content.

According to international practice, sugar-free foods cannot contain sucrose (cane sugar and beet sugar) and starch sugar (maltose, etc.), but must contain substitutes, such as sugar alcohols (including xylitol, sorbitol, maltitol, mannitol, etc.), and cannot be produced with high-intensity sweeteners such as saccharin.

Foods that do not contain sugar are as follows:

1. One of the sugar-free vegetables: lettuce.

Lettuce is an almost sugar-free vegetable, containing York grams of sugar per 100 grams of lettuce, which is 20 times less than pastries of the same weight. And it's so low in calories that you can binge on lettuce leaves without worrying about your waist getting thicker. It is particularly healthy and can boost immunity as it is rich in folic acid, manganese and iron.

Lettuce also contains essential B vitamins and other vitamins, such as vitamins A, C, D, E, and K.

2. The second non-sugar vegetable: asparagus.

In many countries, asparagus is used for ** diseases, mainly as a diuretic, and also to speed up metabolism. Asparagus contains almost no fat and sugar, and contains many important nutrients such as vitamins A, C, E, K, B6 and minerals such as iron, copper, folic acid, and is also rich in protein.

3. The third non-sugar-free vegetable: broccoli.

This dark green leafy dish contains almost no fat and less sugar. It contains many essential nutrients, such as vitamins A, C, D, E, K, dietary fiber, calcium and other nutrients including iron, phosphorus, zinc and potassium, and it is also one of the strongest antioxidants that can scavenge free radicals that are harmful to the body.

4. The fourth non-sugar-free vegetable: cabbage.

Cabbage is also a vegetable that contains almost no fat and sugar, and is rich in vitamins A, C, D, E, and K, and also contains a lot of minerals such as calcium, iron, magnesium, zinc, sodium, etc., which has many health benefits.

5. The fifth non-sugar vegetable: carrots.

Carrots are rich in vitamins have a good antioxidant effect, carrots contain a lot of carotene, which can remove free radicals in the body, so eat more carrots, cabbage and other carotene-rich vegetables in the daily diet, which can effectively lower blood sugar.

According to the amount of sugar in food, people divide it into three categories: high-sugar, low-sugar, and sugar-free foods. Foods with a higher sugar content mainly include table sugar and various grains. Low-sugar foods mainly include vegetables, fruits, and meat. Sugar-free foods mainly include various edible vegetable oils.

The choice of fruit is mainly based on the sugar content and starch content of the fruit.

Recommended: cucumber, watermelon, orange, grapefruit, lemon, peach, plum, apricot, loquat, pineapple, strawberry, cherry, etc. Such fruits contain less than 10 grams of sugar per 100 grams of fruit and provide 20-40 kcal of energy per 100 grams.

Vegetables without sugar: bean sprouts. Onions. Porphynia. Lentinula edodes. And a chili.

Cucumbers, pumpkins, and tomatoes contain 2% sugar, watermelons and melons contain 4%-5% sugar, and grapes, cherries, pears, lemons, oranges, peaches, plums, pomegranates, oranges, loquats, grapefruits, bayberry, apples, pineapples, etc. contain less than 12% sugar.

Generally, according to the different structure of sugar molecules, it is divided into monosaccharides, disaccharides and polysaccharides.

Then let's talk about monosaccharides first, what is a monosaccharide, which is a sugar monosaccharide composed of a sugar molecule. According to the number of atoms, it is also called triose, butyrose, pentose, hexose. But the most practical things in our lives are hexose-based, mainly glucose and fructose.

1) Glucose: The most common monosaccharide is found in fruits, vegetables and human blood in a free state, and can also be found in maltose, sucrose, starch, cellulose, glycogen and other glucose derivatives in a combined form.

Glucose is an important component of blood and an essential energy source for maintaining the physiological functions of the brain. When the glucose content in the blood is less than 600 mg to 100 mg, it is hypoglycemia, which can lead to dysfunction of brain tissue, dizziness, palpitations, cold sweats and hunger; When the amount of glucose in the blood drops below 45 milligrams to less than 100 milligrams, a coma occurs, and the person is in shock. At this time, it is necessary to infuse and replenish glucose, which shows the importance of glucose to the human body.

2) Fructose: Known as the sweetest sugar among natural sugars, honey contains a lot of fructose, so honey is very sweet. The molecular formula of fructose and glucose is the same, the structure is similar, and it is an isomer, but the sweetness of fructose is 2 3 times that of glucose, so the industry uses glucose isomerase to convert glucose into fructose, which greatly increases the sweetness of sugar.

All that is obtained by the hydrolysis of corn starch is glucose, which is then converted into fructose with isomerase, called fructose syrup, which can be used to make beverages, foods and pastries.

This time, let's talk about it first, and next time we will learn about Shuangtang.

Protein, lean meat, milk.

Eggs, fish, etc.

Sugars, rice, flour, fruits, etc.

I don't know why I want to know why I want to choose sugary protein foods for the community?

The protein content of eggs is very high: eggs are rich in high-quality protein, and the protein contained in two eggs is roughly equivalent to the protein of 3 taels of fish or lean meat. Egg protein also has the highest digestibility in milk, pork, beef, and rice.

Eggs are particularly rich in methionine, an essential amino acid that is lacking in both cereals and legumes, so mixing eggs with cereals or legumes can improve the bioavailability of the latter two.

1.Lean meat, dairy products, poultry eggs, and leguminous seeds of cryptophytes all contain a lot of protein.

2.Vegetable oils and animal fats are both fats.

3.Flour, rice, and corn all contain a lot of polysaccharides (carbohydrates).
