There’s a “heart attack risk in dieting”, according to the Daily Express, while The Daily Telegraph reported that a “breakfast egg can raise heart disease risk”. Neither of these over-the-top headlines clearly represented the research on which they were based.
The news stems from a large, long-term Swedish study of women aged 30 to 49, looking at their diets and whether they developed cardiovascular disease. Researchers wanted to understand the long-term effects of low-carbohydrate, high-protein diets. They found that proportional decreases in carbohydrate intake and increases in protein intake were associated with a small increase in the risk of cardiovascular disease such as heart attack and stroke.
