Are black beans really more nutritious than soybeans?

Soybeans and black beans are both soybeans and contain high-quality protein

Usually people say that soybeans are not only soybeans, but also black beans, edamame and other beans. Soy foods have many common characteristics. Soybeans are full of nutrients and rich content, and soybeans are rich in high-quality protein, unsaturated fatty acids, calcium and B vitamins, which are an important source of high-quality protein in the diet of Chinese residents. Soybean protein content is about 35% to 40%, in addition to methionine, the composition and proportion of the remaining essential amino acids are similar to animal protein, and rich in cereal protein deficiency of lysine, is a natural ideal food complementary to cereal protein. The amino acid composition of soybean protein is similar to that of animal protein, in which amino acids are relatively close to the ratio needed by the human body, so they are easily digested and absorbed. If soybeans are eaten with meat foods and egg foods, their nutrition can be compared with the nutrition of eggs and milk, and even exceed the nutrition of eggs and milk.

Soybean fat also has high nutritional value, this fat contains a lot of unsaturated fatty acids, which are easily digested and absorbed by the human body. And soy fat can block the absorption of cholesterol, so soybeans are an ideal nutrient for patients with arteriosclerosis. Soybeans also contain about 1.5% phospholipids. Phospholipids are the basic components that make up cells. It plays an important role in maintaining the health of people's nerves, liver, bones and skin.

Soybeans are rich in inorganic salts such as calcium, phosphorus, magnesium and potassium, and also contain trace elements such as copper, iron, zinc, iodine, and molybdenum. The calcium, phosphorus and protein in soybeans are combined and easily digested and absorbed by the human body; iron and iodine are very important to the human body, people with iron deficiency will get anemia, people with iodine deficiency will get goiter; trace element molybdenum can inhibit carcinogens that produce cancer.

Black beans contain more high-quality protein and other phytochemicals

Although black beans and soybeans are very similar in nutritional value, black beans still exhibit many more powerful functions than soybeans. In terms of high-quality protein, the protein content in black beans is as high as 45%. Among them, high-quality protein is about 1/4 higher than soybeans, ranking first among all kinds of beans, so it has also won the reputation of "the king of beans". The proportion of fatty acids in black beans is better than that of soybeans, and the fat content is lower than that of soybeans, which is a more "high protein and low fat" healthy ingredient.

In addition, black beans contain black bean ash. Ash is one of the six major nutrients of food, and all kinds of inorganic salts needed by the human body come from the ash content of food, so the amount of ash content can reflect the nutritional value of food from one aspect. The ash composition and content of different foods vary greatly, so ash is an indicator of the total amount of inorganic components in food. The ash content in black beans is 4.47%, which is significantly higher than that of other beans.

In addition, black beans also contain black bean saponins. Black bean saponins have a protective effect on DNA damage to the genetic material. In terms of scavenging reactive oxygen species, saponins also have a good effect, the mechanism of which may be that saponins terminate the chain reaction of free radicals, inhibit the peroxidation of more unsaturated fatty acids on the biofilm, remove lipid peroxidation products, and then play a good antioxidant effect from the side, which is more beautiful than soybeans.

Finally, black beans also contain black bean pigments that are not found in soybeans. Black bean pigment is one of the important biologically active substances of black bean, and the natural pigment prepared with black bean skin as raw material is called "black bean red pigment", referred to as "black bean red". Black bean red pigment can reduce the content of lipid peroxidation reaction end products, with obvious antioxidant effect.

Black beans and soybeans together with soy milk nutrition is better

Black beans and soybeans are the same as high-protein, low-fat, low-carbohydrate soybeans, which can be beaten together with soy milk, and the nutritional value is higher than that of simply beating soybean milk with black beans or beating soybean milk with soybeans. The specific methods are: 1. soak the soybeans and black beans well; 2. Put the soaked soybeans and black beans into the soybean milk machine; 3. Turn on the switch and select the whole soybean milk to grind the soybean milk; 4. Until the soybean milk machine has a dripping sound, turn off the soybean milk machine; 5. Filter the soybean milk; 6. Put the filtered soybean milk into the bowl. Finally, add a little white sugar or honey according to your taste preferences, and you can enjoy a bowl of sweet and delicious and nutritious soy milk!
