Everyone these days have an opinion about soya products. Either you believe it is better than dairy; that it is not good for you and your hormones, or that soya itself is not good for you. So what’s the real deal?
Soya and dairy
Soya and dairy are two different things. Many experiences a dairy sensitivity, often due to protein (whey or Cassini), or to the sugar lactose. Soya can be a handy alternative for milk in your latte, or in baked goods. However, the soya protein is quite similar to the milk protein. It is therefor a chance you will react to soya over time as well.
Soya and Hormones
Soya, or its isoflavones phytonutrient component, can have an impact on estorgen levels in the body
Dietary soya, might not have to much of an effect. However, the subtype of isoflvanieds called genistein has in research significantly impacted hormones levels. A Cocharne study on hot flushes and phytoestrogens stated that genistein , with a dose of 30 to 60 mg per day could impact hot flushes in menopausal women. However, it is not as strong as artificial oestrogen, so for best effect, diet, stress-levels and lifestyle must also be dealt with.For women with high risk of breast or endometrium cancers, soya products should be used carefully and in conjunction with a healthcare professional.
For younger women, isoflavones can be useful with PMS and high estrogen levels as the isoflvnoid will bind to estorgen receptors, making sure that excess estrogen is not floating around in the blood causing trouble. That does not mean if you don’t have excess oestrogen for example, it can be damaging to consume soya products as it only have a effect if it binds to the receptor.
It is believed that phytoestrogens, like soya products, is the key reason for why women in Japan don’t suffer to the same degree in the menopausal transition.
Your take away point
If you can tolerate soya, drink it in moderation. If you suffer from excess oestrogen or are in menopause, soya or geinstein can be useful. Be careful if you ar at risk for breast cancer.
