Not just porridge but whole-grain foods in general.
Scientists at Harvard School for Public Health studied 100,000 people over 14 years. During that time almost a quarter died but those who ate the most whole grain, including brown rice, corn and quinoa, lived the longest.
For every ounce of whole grains consumed in a day – equivalent to a small bowl of porridge – there was a 5% drop in mortality. This was mainly accounted for by a 9% fall in cardiovascular deaths.
The scientists couldn’t find a link between whole grains and cancer however.
The research was published in the Journal of the American Medical Association.
A spokesperson for the British Heart Foundation said that people who ate whole grains tended to have healthier life-style anyway but switching to high fibre foods was always a good idea.
