Popular diet doesn't only reduce hypertension, but risk of depression as well, per study

ABC News' Dr. Jennifer Ashton shares what you need to know.

A study, to be presented at the American Academy of Neurology’s 70th Annual Meeting in April, shows that the popular diet -- rich in vegetables, fruit, whole grains, fat-free or low-fat dairy products and very few foods that are high in saturated fats and sugar -- does more than what has been shown in multiple studies: Lowering blood pressure, bad cholesterol (LDL) and body weight.

“Making a lifestyle change such as changing your diet is often preferred over taking medications, so we wanted to see if diet could be an effective way to reduce the risk of depression,” Cherian added.

Almost 1,000 adults with an average age of 81 were followed for an average of six-and-a-half years.

The odds of becoming depressed over time was 11 percent lower among the adults who followed the DASH diet more closely. The group that followed a Western diet -- high in saturated fats and red meats, low in fruits and vegetables -- were more likely to develop depression.

The Mediterranean diet recommends emulating how people in the Mediterranean region have traditionally eaten, with a focus on foods like olive oil, fish and vegetables. U.S. News and World Report called the diet a "well-balanced eating plan" when placing it at the top of its best diets for 2018 list in January.

What is the DASH Diet?

The DASH diet has been ranked as the No. 1 overall diet by U.S. News and World Report for eight consecutive rankings. It tied this year in the No. 1 spot with the Mediterranean diet in U.S. News and World Report’s ranking.

"The thing about the DASH diet is you’re eating specifically the foods you’ve always been told to eat, pretty much fruit, vegetables, whole grain, lean protein and low-fat dairy," Angela Haupt, assistant managing editor of health at U.S. News and World Report, told ABC News in January. "And it eliminates foods high in fat and sugar-sweetened drinks and sweets."

What do findings mean for Americans and their families?

That something as simple as your diet can affect you in multiple ways, according to ABC News' senior medical correspondent, Dr. Jennifer Ashton -- something like depression isn’t just happening in the brain.

“The more we can integrate that, the better,” Ashton said.
