What Is the DASH Diet? Everything You Need to Know, According to Registered Dietitians

 

You may be able to lose weight on this top-rated program, but it’s really designed to help lower your risk of heart disease.

While it didn’t enjoy the same spotlight this January, the DASH diet was crowned as one of the best diets in the United States in 2019 by U.S. News and World Report, putting it on the fast-track to cause buzz on Instagram feeds all year long. In fact, the DASH diet had earned this distinction for most of the 2010s, but unlike many of the other diets we’ve seen percolating in our social media feeds for the last few years, the DASH diet actually has overwhelming support from the medical community — largely in part because it was developed in the 1990s by a team of researchers funded by the National Institute of Health.

Believe it or not, scientists first created this diet plan in response to the rise of cardiovascular disease in the United States, and many doctors only speak about the specifics of the DASH diet with their patients if high blood pressure is a factor for them. The DASH diet targets high sources of sodium and artery-clogging sources of fat to empower dieters to better their own heart health, but in the process, it targets some ingredients that some experts may find controversial.

Stefani Sassos, MS, RDN, CSO, CDN, a registered dietitian within the Good Housekeeping Institute, says that while the Mediterranean diet is worthy of it’s “best” title this year, the DASH diet remains one of her favorite picks of all time. If you’re dealing with elevated blood pressure or other cardiovascular risks, there’s no question about it; but even if you’re looking to lose weight before hitting the beach this summer, the DASH diet may be safer for you compared to the keto diet or Whole30.

Here’s everything you need to know about the DASH diet, including what you can (and can’t eat), how it could help you eat healthier and lose weight, and how to get started.

Sassos has a clinical background in treating cancer patients in the New York area, but also has found herself thrust into understanding the ins-and-outs of the DASH diet as heart disease is actually the number one killer in the U.S., she says. “I had quite a few patients who passed away from heart disease rather than their actual cancer,” she explains. “There’s a huge sodium issue in America, and the DASH diet is specifically known to fight this trend.”

Ginger Meyer, MS, RDN, CSSD, LD, a registered dietitian specializing in sports dietetics within the University of Missouri Health Care system, says the DASH diet successfully lowers blood pressure in patients with hypertension by targeting dietary sources of fat and largely scaling back or eliminating red meat and sugar altogether. In studies since its inception, the DASH program can further lower blood pressure if sodium is also targeted, she says.

“Some may experience lowering of blood pressure in a few weeks,” Meyer explains. “Other important lifestyle factors include achieving or maintaining a healthy body weight, participating in two hours and 30 minutes of moderately intense physical activity each week, and limiting alcohol consumption.”
