The scientific name of ginkgo is ginkgo. Many people know about ginkgo, but they don’t know what nutrients it has. This article will describe it in detail.
First, let us take a look at the nutritional content of ginkgo. According to experiments [1], the starch content in the kernels of ginkgo is about 63%, the crude protein content is about 12%, the crude fat content is about 2.7%, the sucrose content is about 5%, and the reducing sugar content is about 1%. , the nuclear protein content is about 0.26%, the crude fiber content is about 1.2%, and the mineral content is about 3%. In addition, ginkgo also contains a variety of amino acids and vitamins. In general, ginkgo contains a variety of nutrients such as starch, protein, lipids, amino acids and trace elements, especially starch. Starch can be converted into glucose in the human body, so eating ginkgo can supplement carbohydrates. compound.
When we evaluate a food to have high nutritional value, its protein must not only contain a complete range of essential amino acids, but also have an appropriate proportion of essential amino acids. Generally, the higher the proportion of essential amino acids, the higher the proportion of essential amino acids. The nutritional value of the food is also higher. Research[2] has confirmed that the amino acid content in ginkgo accounts for about 12%, including 17 kinds of amino acids, of which glutamic acid has the highest content, followed by aspartic acid and leucine, and the lowest contents are methionine and cystine. , In addition, ginkgo contains 8 kinds of amino acids essential to the human body, such as leucine, lysine, and histidine, among which the content of essential amino acids accounts for about 38% of the total amino acid content. In general, the nutritional value of ginkgo is considered to be very high. High.
Next, let’s analyze what functionally active substances are contained in ginkgo. Research [1] shows that the functionally active substances contained in ginkgo mainly include ginkgo polysaccharides, ginkgo flavonoids, ginkgolides, and ginkgolic acid. , antibacterial proteins, etc. Among them, Ginkgo polysaccharide has multiple functional effects such as immune regulation, anti-tumor, and anti-aging; flavonoids have the functions of eliminating oxygen free radicals, antioxidant, anti-allergic, anti-radiation, and inhibiting tumors. At the same time, flavonoids The compound also has the physiological functions of lowering blood pressure, lowering blood lipids, lowering blood sugar, lowering cholesterol and reducing blood viscosity, and is very beneficial to protecting the cardiovascular and cerebrovascular systems and regulating endocrine functions; Ginkgolide has good effects on myocardial ischemia, arrhythmia and immunity. System regulation plays an important role; ginkgolic acid has antioxidant, anti-inflammatory, anti-tumor, anti-allergic and other effects; antibacterial proteins have inhibitory effects on some fungi and bacteria.
But we must know that we should not eat too much ginkgo. There are many cases of food poisoning caused by eating too many ginkgo. According to statistics [3], the average toxic dose of ginkgo is 35 ginkgo ingested at one time. However, everyone has different tolerances, and there are cases of poisoning after ingesting 10 to 60 ginkgo nuts. According to research[4], this toxic component contained in ginkgo seeds can cause convulsions and loss of consciousness. Its scientific name is ginkgo toxin. According to the average poisoning dose, for safety reasons, it is best not to eat more than 20 ginkgo seeds at one time.
Although ginkgo contains these functional active substances, it does not mean that eating ginkgo can achieve the purpose of treating diseases and preventing cancer. Based on the risk of food poisoning if too much ginkgo is eaten at one time, and what we eat every meal The amount of ginkgo that can be eaten is very limited, and the amount of these active functional substances that can be absorbed through ginkgo is far less than the clinically effective dose. It can only be said that ginkgo has medicinal value. If you want to cure diseases, you need to use it. These active functional ingredients are extracted and made into medicines, which are effective only if they are taken regularly and quantitatively according to the doctor's instructions.
In general, ginkgo contains a variety of nutrients, and the starch content is relatively high. People eating ginkgo can supplement carbohydrates. Although ginkgo contains a variety of active functional substances, Eating ginkgo fruits cannot cure diseases, and you should not eat too many at one time, preferably no more than 20.
