Prior studies have examined the effects of the Dash diet on the incidence of heart failure, and they have yielded some results.

Following the Dash diet can reduce the risk of developing heart failure by almost half.

The study recommends cutting five things out of your diet: This Dash diet recommends fruits, vegetables, nuts, whole grains, poultry, fish and low-fat dairy products, while reducing consumption of three main components: salt, red meat, sweets and sugar-sweetened beverages.

It is very similar to the Mediterranean diet, but the Dash diet recommends cutting out two more things: full cream (in favor of low-fat dairy products) and alcoholic beverages.

(Dash is an acronym for Dietary Approaches to Stop Hypertension.)
