Mediterranean diets like all others are variable but the general theme is that they tend to be high in fruit and vegetables, high in olive oil compared with dairy fats and lower in meat than in the UK.
A recent analysis of 500,00 people from 50 studies was published in the Journal of the American College of Cardiology was reviewed by the team at “Behind the Headlines.”
“Importantly, some of the analyses combined studies that were very different from one another in terms of the sample size, study duration, trial quality and context of intervention. These analyses had a high ‘statistical heterogeneity’, which is a way of measuring whether it is appropriate to pool them or not (higher heterogeneity means pooling is less appropriate). The researchers say that this “introduces a warning about the generalisation of the present results”.
The outcomes were related to risk factors for cardiovascular disease, not the disease itself. It is, therefore, an extrapolation, although perhaps not an unrealistic one, to claim that this study proves that the Mediterranean diet has an effect on cardiovascular disease outcomes.
Overall, this research provides further evidence of the benefits of eating a Mediterranean-style diet and quantifies the benefit in terms of the individual risk components of metabolic syndrome.”
