Effectiveness of Changes in Diet Composition on Reducing the Incidence of Cardiovascular Disease.

To highlight dietary changes shown to be associated with a lower risk of cardiovascular events in epidemiological studies and that have been proven to be effective in preventing cardiovascular diseases in clinical trials RECENT FINDINGS: Since dietary changes always involve multiple variables, recent observational and intervention studies on dietary prevention of cardiovascular disease focus not only to the limitation of a single nutrient/food intake but also to the other dietary changes implemented to replace it. The available evidence supports three major dietary strategies for cardiovascular disease prevention: (1) the replacement of saturated fat with unsaturated fat and/or fiber-rich carbohydrate foods; (2) the reduction of salt intake; (3) the implementation of dietary patterns resembling the traditional Mediterranean diet. This support derives not only from RCTs but also from the combination of large observational cohort studies and relatively short-term randomized trials on cardiovascular risk factors.
