Fibre as a natural part of our diet, improves our fat and sugar metabolism, blood vessel function, helps control blood pressure and facilitates weight loss. Our bodies evolved on fibre-rich foods and we need plenty to be healthy. A recent study looked at the diet of people who had suffered a heart attack in order to assess how changes in their diet post-heart attack might influence their health and survival chances. Those who changed their diet and increased their fibre intake post heart attack had significantly higher chances of survival. In particular, greater intake of fibre from wholegrains was found to be very beneficial. Increasing fibre consumption was also strongly associated with lower mortality from all causes, as well as cardiovascular disease.
