Often eat bean product can cause female to suffer from breast cancer?
Soybean itself contains soybean isoflavones, which are phytoestrogens. Hearing such a name, many people who don't understand the substance and are irresponsible have heard that women who consume a lot of soybean products will suffer from breast cancer.
Through careful analysis of soybean isoflavone, its molecular structure is similar to human estrogen, and it can bind to human estrogen receptor, so it is called 'phytoestrogen'. However, unlike animal estrogens, this kind of plant estrogens have very low activity, only about one thousandth of animal estrogens. What's more, estrogen can play a role only when it is combined with estrogen receptor.
Because the biological activity of phytoestrogens is only one thousandth of that of estrogens, a cup of soy milk is not enough for the general population to cause significant changes in estrogen levels. When the intake of phytoestrogens is high, it has a slight inhibitory effect on androgen. As long as the intake dose is small, it is impossible to reverse the hormone balance and affect the normal development of male sexual characteristics or boys.
Under normal circumstances, the proportion of estrogen and estrogen receptor in human body is at a reasonable and appropriate level. 'soybean isoflavones' have little effect on the amount of estrogen in the body.
In other words, you should understand the 'two-way regulation' function of soybean isoflavones (phytoestrogens), that is to say, drinking soybean milk can't change the hormone changes in your body at will, so the crazy talk about 'eating soybean products to cause breast cancer' on the Internet is a complete rumor.
Can drinking lemonade have the effect of whitening?
When it comes to whitening and skin care, it should be a topic that many women care about, so it is not uncommon to talk about women's whitening and skin care, such as the old saying 'pigskin, pig's hoof whitening', eating sheep's hoof can beautify 'and other topics; read the recent Internet hot spots carefully, and some people say' drinking lime water can whiten ', is this true?
Some people say that drinking more lemonade can whiten, mainly because of the vitamin C component contained in lemons. Vitamin C does have the physiological function of whitening and antioxidation, but does that mean eating lemons can whiten?
Vitamin C does have a whitening effect, but the content of vitamin C in lemon is not high, only 22mg / 100g, not only that, for lemonade, after the "destruction" of air and water, the vitamin C contained in it is not the height of lemon fruit. On the other hand, if you want to drink lemonade to supplement vitamin C, it's better to eat cabbage (31mg / 100g).
Therefore, the saying that drinking lemonade can turn white doesn't hold true. Goddess, please detour.
Drink lemonade to lose weight?
In addition, some people say that drinking lemonade can reduce weight, which is not reliable.
It is said that lemon is rich in acid substances, which can 'detoxify and degrease'. However, there is no scientific experiment to prove that acid substances can prevent fat absorption; What's more, in the human small intestine, the human body will secrete alkaline substances, which can neutralize stomach acid and other acidic substances, so 'acid' will not play such a magical role in the subsequent digestion and absorption.
