Magical fermented soy milk, after eating can be sunscreen!

study published in the journal Nutrition found that ingesting fermented legumes could prevent damage caused by UV radiation by increasing the amount of isoflavone compounds in the body.Researchers from japan's Center for the Study of
SM
and fermented soy milk (
FSM
) were fed and tested on hairless female mice, and found that mice fed with fermented soy milk had less redness or erythema and thicker cartilation of their skin than mice in the regular bean milk feeding group. The researchers believe that eating a diet containing fermented soy milk can increase the concentration of isoflavones in the blood and skin of hairless mice, effectively eliminating the reactive oxygen produced by ultraviolet radiation and protecting the skin from light damage.The study found that although the intake of unfermented soy milk group (
SM
group) can also play a certain protective effect on the skin in the case of ultraviolet radiation, but its protective effect is not good to supplement fermented soy milk group (
FSM
). The
isoflavones in the
FSM
group had higher concentrations of isoflavones in the blood and skin exposed to ultraviolet light than in the
group of
FSM. In addition, without UV exposure,
FSM
and
SM
groups did not have a significant protective effect on the skin.previously, researchers had found that mice fed
FSM
, which is rich in glycosides, were more absorbent of isoflavones than
SM
, which is rich in glycosides. In addition, although the concentrations of dye flavonoids and soybean glycosides in the serum and back skin of the
FSM
group were higher than those in the
SM
group, there was little difference in the concentrations of estrogen in the two groups of mice, which were said to be the most effective isoflavones., the researchers said there was reason to believe that the levels of dye flavonoids and soybean glycosides in mouse serum and back skin were due to the different effects of estrogen in
FSM
and
SM
.The mice were removed from their ovaries before they were put into the experiment, and after the ovaries were removed, the inflammatory reaction caused estrogen loss, which in turn increased the sensitivity of hairless mice to UV radiation and erythema, and insufficient estrogen also weakened their defenses against oxidative stress. Preliminary studies have shown that mice that have their ovaries removed are more susceptible to UV-skin damage. The researchers speculate that isoflavones play a "estrogen-like" role here.isoflavones are similar to estrogen structures and can play an estrogen-like role in preventing hormone-dependent diseases.
estrogen-like effects of isoflavones in FSM
compensate for estrogen loss in hairless mice that have under received ovarian removal, as well as prevent skin light damage caused by UV exposure.
