Pumpkins are great for a lot more than making jack-o’-lanterns. One cup of mashed pumpkin has only 49 calories and is loaded with vitamin A in the form of beta-carotene. It also has nearly 3 grams of fiber and 564 milligrams of potassium. Pumpkin also contains vitamin C, lutein and zeaxanthin (good for eye health), as well as iron and zinc.

Pumpkin seeds are loaded with manganese, magnesium, iron, copper, vitamin K, zinc and protein. One ounce has 158 calories, 8.57 grams of protein, 1.7 grams of fiber and almost 25 percent of the recommend daily value for iron. Pumpkin seeds also have plant sterols that can help reduce the risk of heart disease and fight cancer. They are also a fantastic source of omega-3 essential fatty acids. Wash them, dry, and then toast them with garlic and onion powder and a bit of salt and pepper. They take about 30 to 40 minutes at about 300 degrees to toast.
