According to the National Institutes of Health, nearly half of all adults in the United States have high blood pressure. If left untreated, high blood pressure can put more stress on the heart and lead to serious health issues, like kidney disease, damaged blood vessels, heart disease and stroke. Because high blood pressure, also called hypertension, has very few obvious symptoms, many people are unaware they have it, so it's a good idea to get it checked by a medical provider if you're unsure. Fortunately, diet and lifestyle, including weight loss for people with excessive weight, can play a role in lowering blood pressure. In this weeklong meal plan, we limit sodium while incorporating principles of the DASH diet to help keep your heart healthy. The DASH diet, standing for Dietary Approaches to Stop Hypertension, is considered the gold standard for improving heart health and lowering blood pressure. It's similar to the Mediterranean diet, as it also emphasizes a high intake of fruits, vegetables, whole grains, legumes and lean proteins while limiting processed foods, refined grains and excess sodium.
