Theoretically, the average adult should drink 500-700 milliliters per day, and children should drink 200-250 milliliters per day

But 300 milliliters of soy milk per day is the best.

If you squeeze soybean milk at home, the amount of soybeans for each person should not exceed 50 grams at most, and you should add more water to dilute the soybean milk so that it is not too thick and increase the burden on the kidneys. If you drink soybean milk with soybean has reached 50 grams, then other soybean products are best not to eat or eat less; if there is no more than 50 grams, you can properly add some other soybean products intake. Soymilk should not drink too much at once, otherwise it is very easy to cause overfeeding protein dyspepsia, bloating or diarrhea and other discomforts, do not drink more than 800 milliliters per day.
