Barbecues and charred meat Some research suggests that burnt or charred meat may increase the risk of cancer. Substances called heterocyclic amines are formed in foods that are cooked at high temperatures and blackened or charred.eat may affect cancer risk because of the amount of fat in it, the way it is cooked or because big meat eaters miss out on other protective foods such as fruit and vegetables or wholegrain cereals. What we do know is that meat plays an important part in the Australian diet.
High-fat, low-fibre diets may increase the risk of many cancers including bowel, lung, prostate and uterine cancers. You can reduce your risk of developing cancer by eating a wide variety of nutritious foods as described in the Australian Guide to Healthy Eating. Even though diet can influence your risk of developing cancer, there is little evidence that special foods can be used to cure existing cancers.
