Soya Drinking
History
The earliest record of soybean milk is on a stone slab unearthed in China.
The stone slab was made around the Eastern Han Dynasty, and it was engraved with the situation of making soybean milk in an ancient kitchen.
A chapter of "Lun Xing" written in 82 AD also mentioned that the masters who made soybean milk were afraid that thunder would destroy their products.
Chinese traditions generally believe that the origin of soy milk is that Liu An, the filial son of Huainan King in the Western Han Dynasty, used soaked soybeans to grind soy milk for his mother when his mother was sick.
Liu's mother's illness gradually improved, and soy milk was also introduced to the people. In fact, there is no historical support for this statement.
The "Compendium of Materia Medica" written in 1578 A.D. records: "Soymilk can benefit Qi and enter the water, control wind-heat, and detoxify various poisons", "Soymilk is flat and sweet".
But it only shows that Liu An invented tofu instead of soy milk. As early as the 10th century, the tofu poems written by Zhu Xi of the Song Dynasty also mentioned that Liu An made tofu.
Chinese and foreign people list soymilk as Liu An's invention. The main reason is that soymilk is needed to make tofu.
However, some people have suggested that tofu can also use boiled soybean soup instead of filtered soy milk. In ancient times, this thick soup was also called soy milk.
Nutrion
Soymilk is rich in nutrition and health value, rich in protein, calcium, phosphorus, iron, zinc and other dozens of minerals, as well as vitamin A, vitamin B and other vitamins.
However, due to the presence of a large amount of phytic acid, the minerals in soy milk cannot be absorbed and utilized.
In addition, soy milk also contains soybean saponins, isoflavones, lecithin and other special health factors that have the significance of preventing cancer and strengthening the brain.
And because soy milk does not contain lactose, it will not cause side effects for people who are lactose intolerant, and it is also a cheap and good source of protein.
Although soy milk also has calcium, the calcium content of soy milk is relatively low, generally only one-thirtieth of the same dose of milk .
On the contrary, almond milk is rich in calcium. Therefore, compared with plant milks such as nut milk, soy milk has high protein content and low mineral element content.
The existing product "Honey Soy Milk" on the market is soy milk with added sugar, which is more acceptable to the general public in terms of taste, but the high sugar content has the risk of causing cardiovascular disease and diabetes.
Soy milk contains phytoestrogens. Studies have found that phytoestrogens have significant estrogenic effects, and they may trigger many biological reactions caused by physiological estrogen.
