Eating more than the recommended five portions of fruit and vegetables a day can cut risk of stroke, a study says. People who ate three to five cut the risk by 11% compared with those eating fewer than three, The Lancet reported. It was 26% lower for people who ate more than five servings, University of London researchers found in the study of data on more than 257,500 people. The Department of Health says five or more daily portions cuts risk of heart disease, cancer and other problems.

Sea level rise 'is accelerating'
Global sea-levels could rise by about 30cm by the end of this century if current trends continue, a study warns. Australian researchers found that sea levels rose by 19.5cm between 1870 and 2004, with accelerated rates in the final 50 years of that period. The research, published in the journal Geophysical Research Letters, used data from tide gauges around the world.
Floods and surges. Melting ice on Antarctica is a cause of sea level riseIf the acceleration continues at the current rate, the scientists warn that sea levels could rise during this century by between 28 and 34cm.
Dr John Church, a scientist with the Commonwealth Scientific and Industrial Research Organisation based in Tasmania and an author of the study, said that higher sea levels could have grave effects on some areas.
