Eating purple coloured fruit can ward off age-related diseases such as Alzheimer’s, heart problems and cancer, scientists believe.
The odds of developing multiple sclerosis and Parkinson’s disease may also be reduced by consuming blueberries, blackberries, blackcurrants or plums, according to a study by the University of Manchester.
Researchers say one or two of the recommended five daily portions of fruit and vegetable should be purple fruit. It is thought that a compound in purple fruit helps fight the harmful effects of iron, which can damage cells if it makes its way through the digestive system in the wrong form.
Although we are often told of the healthy effects of the mineral, benefits are only felt if it reacts with other compounds in the body. Iron that does not react can prove poisonous to tissue.
