Recent research by the Institute of Food Research showed that pectin – a natural fibre found in fruit and vegetables can block the spread of cancer throughout the body. 

Pectin is found in jam and jelly. It is a processing ingredient in confectionery, bakery fillings, yoghurts and milk drinks. The study showed that pectin binds to and is believed to inhibit galectin 3 (Gal3) – a protein that plays a role in all stages of cancer progression.  

Lead researcher, Professor Vic Morris said: "Most claims for the anticancer effects of foods are based on population studies. For this research we tested a molecular mechanism and showed that it is viable. " 

Researchers added that other food carbohydrates such as beta glucans are considered to be bioactive and their anti-cancer action can be attributed to different types of carbohydrate - mammalian protein interactions.  

He added: "I expect you would get some protection from jam, but it's packed full of sugar. It might be better to get the same protection from fruit and vegetables which would give you other anti-cancer magic bullets as well".

Researchers will conduct a further study to identify how pectin can be taken up by the body and released so it can exert its effect on cancer cells.  
Morris added: The research could result in functional foods with added bioactive pectin. "This first step opens the way to a new and exciting area of research in bioactive carbohydrates.”
