Extra Portions of Wholegrain Foods Reduces Early Death Risk, Study Finds

The researchers from Harvard University's School of Public Health also suggest that doctors should encourage patients to eat extra helpings of wholewheat pasta, as risk of death can be reduced by 7%. Even small amounts of brown rice eaten each day can help prevent an early death.

As third of adults don't eat the recommended amount of wholegrain foods a day, the researchers say the Government should issue new public health advice urging us to eat more wholegrains as the long term benefits are so strong.

 

Although some wholegrain foods also contain sugar and salt which can be detrimental to our health, they contain far lower levels than white bread, rice or processed cereals.

Wholegrains – such as porridge oats, muesli and seeded bread – include carbohydrates which haven't been processed. They are rich in fiber, protein, antioxidants and certain vitamins which are thought to encourage digestion, help weight loss and prevent heart disease, cancer and other illnesses.

 

In the largest study of its kind so far, researchers analyzed evidence involving nearly 800,000 men and women from the US, the UK and Scandinavia. These included research which had looked at their dietary habits, and whether they had died from cancer, heart disease or other natural causes.

 

They found that every 16g portion of wholegrain food reduced the risk of dying from heart disease by 9 percent.

 

The likelihood of dying from cancer went down by 5 percent, and from any other long term illness by 7 percent.

One 16g portion is equivalent to a slice of bread, a small bowl of muesli, or porridge or half a cup of wholewheat pasta or rice.

 

But adults who ate three portions a day – 48g of wholegrain foods – were 25 percent less at risk of dying of heart disease, 14 percent from cancer and 20 percent from any natural cause.

 

There are no official guidelines on wholegrain food in the UK, although experts say the public should aim for at least three portions a day. However, surveys show that only a third of adults manage this and 5 percent don't have any wholegrain food at all.

 

Dr Qi Sun, Assistant Professor at the Harvard T.H. Chan School of Public Health in Boston, whose research is published in Circulation, the journal of the American Heart Association, said health officials including the NHS should change national guidelines to promote a wholegrain-rich diet.

 

He also urged against following low carb diets as these did not allow for enough wholegrain foods.

 

He added: “Previous studies have suggested an association with consumption of wholegrains and reduced risk of developing a multitude of chronic diseases that are among the top causes of deaths, although data linking wholegrain intake and mortality were less consistent.”

 

Victoria Taylor, senior dietician at the British Heart Foundation, said: “Eating more wholegrains is a simple change we can make to improve our diet and help lower our risk of heart and circulatory disease.”

 

“Choosing brown rice, wholewheat pasta, wholemeal or granary bread instead of white and swapping to wholegrain breakfast cereals like porridge are all simple ways to help us up our fiber and wholegrain intake.”

 

Dr Shamim Quadir, of the Stroke Association, added: “It is well known that eating a balanced diet that is high in wholegrain foods is beneficial to your health. This latest study from the US provides further evidence to support this argument.”

 

“Eating a balanced diet, getting enough exercise, and getting your blood pressure checked regularly are all important steps to reduce your risk of having a stroke. If you are at all concerned about your risk of stroke, talk to your GP.”
