Last year was all about the 5:2 diet and the Paleo or 'caveman' diet is already set to be the healthy eating craze of 2014. But there's another one to know - the DASH diet.
The test results proved that the DASH diet had a positive impact on the heart and blood pressure.
"The study enrolled 459 healthy people with slightly high blood pressure and randomly assigned them to follow the DASH diet, a high-fat "American" diet or an American diet supplemented with more fruit and vegetables After eight weeks," the NHS reports.
"The DASH diet lowered blood pressure and cholesterol, and decreased the participants' risk of developing heart disease in the next 10 years more than the other diets."
By minimising the daily intake of fats and oils (DASH recommends three servings a day) and lowering salt intake, the diet will also help with weight loss.
However, the dietary changes aren't as drastic as the low-carbs low sugar Paleo rules. Lean proteins, complex carbs and plenty of fresh fruit and vegetables are the DASH guidelines.
