In addition black beans also contain soy isoflavones, often eat black beans help to balance estrogen, and delay aging, delay menopause, improve the benefits of menopausal discomfort.
2, can promote ovulation
Black beans are rich in soy isoflavones, supplemental estrogen has a very good effect, can regulate estrogen secretion is insufficient or too little, and estrogen helps to increase the thickness of the uterine lining, to stimulate follicular development and fallopian tube development, strengthen the fallopian tubes rhythmic contraction amplitude, and the black beans also contain Fiber and vegetable protein, so that eating more black beans after menstruation has a certain effect on promoting ovulation.
3, black beans how to eat
Eating black beans after menstruation should be in the first day after the menstrual period is completely clean to eat, eat for six consecutive days, a serving size should not be too much, you can soak 12 hours of children and then put into a pot to cook, put the seasoning, and eat 47 every day; you can also use 30 grams of black beans and 60 grams of glutinous rice porridge, every day, to eat.
4, eat black beans to pay attention to what
Eat black beans should pay attention to, black beans cortical hard, contains a component called anti-trypsin, will affect the digestion and absorption of protein, so poor digestion of the crowd is not advisable to eat, and furthermore, black beans belong to the high-purinic acid food, gout crowd is not advisable to eat more than one, eat black beans before it is best to soak 12 hours in water. The best thing to do before eating black beans is to soak them in water for 12 hours and then eat them.
5, the efficacy and role of black beans
(1) to prevent brain aging
Black beans contain about two percent of lutein, there is a role in the brain, in addition to calcium, phosphorus, iron, zinc, copper, magnesium, and other trace elements to meet the needs of the brain, slowing down the body's aging, and the role of the brain. It also helps to reduce blood viscosity.
(2) prevention of constipation
Black beans in the crude fiber cold as much as four percent, has a good laxative effect, eat black beans can reduce the burden on the intestinal tract, improve the symptoms of constipation, prevention and treatment of hemorrhoids, the occurrence of intestinal cancer.
(3) improve kidney function
According to Chinese medicine theory, beans for the kidney of the valley, black is water, water goes to the kidney, so the black beans into the kidney function, eat more black beans to help improve kidney function, play a prolonged life, slow down the aging process, and enhance the vitality of the role.
6, black bean nutrients
Black beans are rich in nutrients, containing protein, fat, vitamins, trace elements and other nutrients, but also has a variety of biologically active substances, such as black bean pigment, black bean polysaccharide and isoflavones.
1, protein
Black beans have high protein, low-calorie properties, protein content of up to 45% or more, of which the high quality protein is about 1/4 higher than soybeans, the first of a variety of beans, and therefore also won the "king of beans" reputation. Compared with protein-rich meat, black beans are not only no color, but to be more than a chip, its protein content is equivalent to meat (pork, chicken) 2 times, is 3 times the egg, is 12 times the milk, so it is also known as the "plant protein meat".
2, fatty acids
Research has found that every 100 grams of black beans contain crude fat up to 12 grams or more, which was found to contain at least 19 kinds of fatty acids, and unsaturated fatty acid content is as high as 80%, of which the linoleic acid content accounted for about 55.08%. Linoleic acid as a kind of unsaturated fatty acids, is a very important essential fatty acids in the human body, cholesterol metabolism has a crucial role in regulating cholesterol, only when the cholesterol and linoleic acid combination can be in the body transit and normal metabolism. When linoleic acid is lacking, cholesterol will be combined with saturated fatty acids and deposited in the body, leading to the occurrence of atherosclerosis, therefore, linoleic acid has a "vascular scavenger" reputation.
3, black bean ash
Ash is one of the six nutrients of food, the human body needs a variety of inorganic salts are from the ash of food, therefore, the amount of ash content can be reflected in one aspect of the nutritional value of food. The composition and content of ash in different foods vary greatly, so ash is an indicator of the total amount of inorganic components in food. The ash content of black beans was 4.47%, which was significantly higher than that of other legumes. Further analysis of the composition of black bean ash, can be found in a variety of minerals and trace elements, such as zinc, copper, magnesium, molybdenum, selenium, phosphorus, and so on, and the content are relatively high.
4, vitamins
Vitamins on the importance of human health, it is estimated that we can say some of them, alone literally can guess the general meaning of the word, vitamins - life-sustaining elements. Black beans are rich in a variety of vitamins, especially vitamin E in each hundred grams of black beans containing up to 17.36 micrograms. Vitamin E (VitaminE) is a fat-soluble vitamin, is one of the most important antioxidants, plays an important role in antioxidant protection of the body's cells from the toxic effects of free radicals.
5, isoflavones
Isoflavones are one of the flavonoids, mainly found in legumes, so often referred to as soy isoflavones, because it is extracted from plants, and the structure of estrogen is similar to that of female estrogen, so isoflavones have "phytoestrogens," the name. Early research has confirmed that the soybean is extremely rich in isoflavones, but recent experiments have found that the isoflavone content of black beans is more than soybeans.
6, saponin
Saponin, is a complex structure of compounds present in plant cells, but also an important medicinal value of plant active ingredients. Black soybean saponin has a protective effect on genetic material DNA damage. In scavenging reactive oxygen species, saponin also has a good effect, the mechanism of which may be that saponin terminates the chain reaction of free radicals, inhibits the peroxidation of polyunsaturated fatty acids on the biofilm, scavenges lipid peroxidation products, stabilizes the cell membrane, inhibits the abnormal elevation of the level of calcium ions in the cell membrane system, and ultimately protects the integrity of the biofilm and subcellular structure.
7, polysaccharides
Black soybean polysaccharide is one of the human body to remove free radicals. Research has found that black soybean polysaccharide belongs to the non-reducing, non-starch polysaccharide, has a significant role in the removal of free radicals in the human body, especially on the removal of superoxide anion free radicals is very powerful. In addition, it has been found that the polysaccharide content in black beans can also promote the growth of bone marrow tissue, with the effect of stimulating the regeneration of hematopoietic function.
8, black soybean pigment
Black soybean pigment is one of the important bioactive substances of black beans, black soybean skin as raw material to produce natural pigments known as "black soybean red pigment", referred to as "black soybean red". Black soybean red pigment can reduce the lipid peroxidation reaction end product malondialdehyde (MDA) content, and at the same time improve the superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px) content, which means that the black soybean red pigment has a significant antioxidant effect.
