Whole Grains The Holy Grail of Good Health
Whole grains may be the holy grail of good health, according to a study published in the British Medical Journal.
A higher intake of whole grain bread, whole grain breakfast cereals, and added bran has been shown to lower the risk of major chronic diseases and death.
Researchers found that consumption of 90 g per day of products made with whole grains (one serving equals 30 of whole grain product) is associated with a relative risk reduction of:
- 19 per cent in coronary heart disease
- 22 per cent in cardiovascular disease
- 17 per cent in mortality from all causes
- 14 per cent in mortality from stroke
- 15 per cent in cancer
- 22 per cent in respiratory disease
- 26 per cent in infectious disease
- 51 per cent in diabetes
The health benefits of whole grain foods has been recognized for many years, but recommendations on the amount of whole grain foods needed to reduce risk of chronic disease and death have been unclear.
So an international team of researchers, led by Dr. Dagfinn Aune at Imperial College London, carried out a systematic review of 45 published studies on whole grain consumption in relation to several health outcomes.
The greatest benefit was seen for people who increased from no intake of whole grain to two servings per day, equivalent to 32 g per day, such as 32 g of whole grain wheat or 60 g per day of products with whole whole grains, such as 60 g of whole grain wheat bread.
Further reductions in risks were observed up to 7.5 servings a day, equivalent to 225 grams per day of whole grain products.
