Study (2007) disputes "wholegrain for heart health"

Wholegrain cereals for coronary heart disease  

by the Cochrane Collaboration

[Plain Language Summary]

Wholegrain foods encompass a range of products and examples are wholegrain wheat, rice, maize and oats. The term wholegrain also includes milled wholegrains such as oatmeal and wholemeal wheat.

The evidence found by this review is limited to wholegrain oats, and to changes in lipids as an outcome. There is a lack of studies on other wholegrain foods or diets. There is some evidence from this review that oatmeal foods can beneficially lower lipid levels such as low density lipoproteins (LDL) cholesterol and total cholesterol in those previously diagnosed with risk factors for coronary heart disease (CHD) even with relatively short interventions. However, the results should be interpreted with caution because the trials found are small, of short duration and many were commercially funded. No studies were found that reported the effect of wholegrain foods or diets on deaths from, or occurrence of CHD.
