Nutrition Tip

Pumpkins are synonymous with fall and Halloween, but did you know that this fruit was once called “gros melon,” which was translated from French into the English “pompion?” Although considered a type of winter squash, pumpkins are in fact related to watermelon. Today, there are 45 varieties of pumpkins in all shapes, sizes, and colors. Pumpkins are packed with nutrients, such as fiber, vitamins A, E, and C, iron, folate, potassium, and B vitamins. While canned is the most common form of pumpkin sold in the U.S. and incorporated into pancake and muffin recipes, try mashed or roasted pumpkin, or make into a delicious soup. And don’t forget the seeds. This nutrient-dense snack provides a great source of iron, magnesium, zinc, copper, and iron.
