Oestrogen is known as the female sex hormone, but everyone will produce it - men and women. Yes, men produce oestrogen and it's very important for them, but when the balance goes wrong it's not good. Oestrogen in men is used to help bone growth and control metabolic processes and has no real negative effects until it's thrown out of balance with testosterone.
When the levels of oestrogen in men’s bodies climb higher and higher, without increase in testosterone to level it out men can be affected negatively. Putting on fat and weight, increasing risk of heart disease and osteoporosis and even reduced libido are all effects of high oestrogen levels.
Normally this wouldn't be seen until men start to age and their testosterone levels start to decline due to natural processes, but in recent years the effects are starting to impact more and more people earlier in their lives. But why? The reason could lie in what we eat and how we store certain foods. Some plants have chemicals and compounds in them that are very similar to oestrogen, and in fact mimic the effects of oestrogen in our bodies. These are called 'phyto-oestrogens' and are particularly abundant in soya, cereal and bread. Another source of additional oestrogen is plastic food and water storage containers. Certain plastic, especially when heated, will release chemicals known as 'xeno-oestrogens' into the food and water they contain, once again increasing the levels of oestrogen like hormones in your body.
So what to do? Well, the answer is pretty simple in terms of concept but a bit harder to do in real life - give it a go. Reduce your soya, bread and cereal in take (good general advice too) and try to avoid food and drink that's been stored in plastic containers for long periods of time (again, good advice as this is generally processed food).
That advice is pretty similar to the advice given about having a general healthy diet so shouldn't be too much more to think about. One thing to be aware of though, is some nuts and seeds do have phyto-oestrogens in them so don't go crazy on them - it's about moderation and a varied diet too!
