Oestrogen is a perfectly normal, health-promoting hormone, but in excess it can contribute to a host of problems..

There are many ways to become oestrogen dominant, and many ways to avoid it. Let's look at these in turn and see what you can do to keep these health-promoting hormones in balance.

Environmental Oestrogens

Although it is impossible to quantify, there is little doubt that our exposure to some 70,000 man-made hormone-disrupting chemicals is part of the reason for the explosion in breast and prostate cancer. Many of these compounds, from the now banned pesticide DDT and the most insidious of all industrial pollutants, PCB's, mimic oestrogen by virtue of having a similar structure involving something called a 'phenol' ring. PCB, for example, stands for poly-chlorinated biphenyl. Many of these phenolic compounds are like poison to the body, and can sometimes latch onto the oestrogen receptor sites on cells triggering abnormal growth messages.

When Israel, which used to have one of highest incidences of breast cancer, banned DDT, BHC and Lindane - all hormone-disrupting chemicals - the incidence of breast cancer dropped by 8 per cent. So, what can you do to minimise your exposure? Avoid the most harmful sources and switch to alternative foods, toiletries, household products and packaging.

The Key Chemicals to Avoid are:

• Pesticides and herbicides - DDT, DDE, endosulfan, methoxychlor, heptachlor, toxaphene, dieldrin, lindane and atrazine
• Plastic compounds - alkyphenols, such as nonylphenol and octylphenol; biphenolic compounds, such as bisphenol A; and phthalates
• Industrial compounds - some PCBs (polychlorinated biphenyls), dioxin, plus those listed for plastics • Cosmetics - parabens
• Foods - butylated hydroxyanisole (BHA, an antioxidant)

Check your bathroom products, washing up liquid, dishwasher and washer detergents for the chemicals listed above. If you find them included, switch to a different brand. These very flexible plastics may contain the above chemicals.

  • Buy and eat organic fruits and vegetables as much as possible.
  • Avoid fatty foods, like cheese, wrapped in cling-film.
  • Reduce your intake of animal fats (meat and milk) which are more likely to accumulate hormone-disrupting chemicals.
  • Choose organic if you can.

HRT and the Pill

Against this background of potential over-exposure to oestrogen-like chemicals, taking the birth control pill or HRT can encourage too many oestrogen growth messages. The birth control pill is a greater risk factor the higher the dose, ......
