Lentils and beans are great foods for weight loss, but chickpeas also belong in your pantry. They contain a whopping 39 grams of protein per cup, which nearly meets your recommended daily amount from the USDA, so you're guaranteed to stay full for awhile after noshing on these beauties. Most eat them in hummus form, but you could also toss them in seasonings and roast in the oven, which you can then sprinkle into meals or eat alone for a crunchy snack.
The DASH diet (Dietary Approaches to Stop Hypertension) is a diet promoted by the National Heart, Lung, and Blood Institute (part of the NIH, a United States government organization) to control hypertension. A major feature of the plan is limiting intake of sodium, and the diet also generally encourages the consumption of nuts, whole grains, fish, poultry, fruits, and vegetables while lowering the consumption of red meats, sweets, and sugar. It is also "rich in potassium, magnesium, and calcium, as well as protein".
