Roasting and frying starchy foods 'could' increase cancer risk

Roasting and frying starchy foods could increase the risk of cancer, according to the British Food Standards Agency.

The FSA has issued a public warning over the risks of acrylamide - a chemical compound that forms in some foods when they are cooked at high temperatures (above 120C).

A new campaign tells people how they can cut their risk, including opting for a gold colour - rather than darker brown - when frying, roasting, baking, grilling or toasting.

Acrylamide is found in high levels in a range of foods including breakfast cereals (not porridge), chips, potato products (such as waffles or potato shapes), biscuits, crackers, crispbread and crisps.

It is also found in coffee, cooked pizza bases, black olives and cereal-based baby foods.

Root vegetables including potatoes, sweet potatoes, beetroot, turnip, swede and parsnips can all carry high levels of the compound once they have been roasted or fried until darker brown or crispy. As well as high temperatures, long cooking times can increase levels of acrylamide even further.

Foods such as skinny fries and crisps appear to have the highest levels.

Acrylamide forms due to a chemical reaction between certain sugars and an amino acid (asparagine) in the food.

However, boiling, steaming and microwaving appear far less likely to cause the reaction.

Studies in mice have shown that high levels of acrylamide can cause neurological damage and cancer.

While studies in humans have proved inconclusive, experts believe the compound has the ability to cause cancer in humans.
