The UK Food Standards Agency (FSA) has started a campaign to warn people that burnt toast, over-roasted potatoes, and starchy foods cooked at higher temperatures can cause cancer. Cook food only to a golden color as brown and black can be unhealthy for you.
Campaigners say leaked documents show "undue influence" by the food industry after plans to limit acrylamide - a subtance found in starchy foods such as crisps, cereals and baby foods, are reduced.
A study has found that exposing bread, potatoes and other starchy foods to very high temperatures can produce toxins that can cause cancer.
