British researchers have found evidence that too much meat in the diet can be deadly. Studies have shown that eating just one sausage a day can raise the risk of bowel cancer. After lung cancer, bowel cancer is the deadliest forms of the disease.

Although bacon and sausages are Britons favorite foods, only one in three know the real dangers of these processed foods. Eating 1.8oz (50g) of processed meat a day, which is an equivalent of one sausage or three rashers of bacon, raises risks of the cancer by one fifth.

Processed meats include bacon, ham, pastrami, salami, hot dogs and any other meat preserved by smoking, salting, chemical additives and any other method apart from freezing.

World Cancer Research Fund in UK recommends avoiding any type of processed meats. For those who can’t avoid it completely, cutting down would also reduce the overall risk. However, the safest amount is none.
Researchers report that dangers lie behind the fact that two-thirds of people don't know about the link between processed meat and bowel cancer and are therefore not able to make informed decisions about whether to eat it or not.

Processed meats may also trigger cancer in the prostate, lung, stomach and oesophagus.

Red meat has also been found to raise the risk of cancer, but to a lesser extent than processed meat. Both red and processed meat has been found to be high in iron and fat, both of which are linked to cancer.
On the other hand, meat is a good source of protein as well as vitamins B and D and minerals such as iron and zinc.

Experts advise that people should not eat red meat every day and that 18oz (500g) a week in cooked weight is sufficient while processed meat should be avoided all together.
