Soya not only destroys forests and small farmers - it can also be bad for your health

Anderson's 'eureka' moment arrived when a complex analysis of the samples she was working on revealed that the seminal liquid surrounding the slower-moving sperm contained chemicals called isoflavones. These compounds are also known as phyto-oestrogens or plant-oestrogens because they mimic oestrogen, the powerful female hormone.

These highly active compounds are found in large concentrations in soya. Indeed such are the doses of these chemicals, a woman drinking two glasses of soya milk a day over the course of a month will see the timing of her menstrual cycle alter. It has been estimated that infants who are fed soya formula exclusively receive an amount of oestrogen equivalent to five birth control pills every day.
