Seaweed could hold the answer to tackling obesity, according to Newcastle University researchers. The team found a fibre in seaweed that reduces the body’s fat uptake by more than 75%. That is better than most anti-obesity treatments. Now the fibre is being added to bread in an effort to develop foods that help lose weight. Clinical trials are now intended to find out how effective it would be in a normal diet. Dr Iain Brownlee, who co-led the Tyneside team, said: "This research suggests that if we can add the natural fibre to products commonly eaten daily, such as bread, biscuits and yoghurts, up to three quarters of the fat contained in that meal could simply pass through the body."
