A berry is any fruit without a pit that forms from a single flower with a single ovary. Grapes, blueberries, tomatoes, and squashes are all true berries.
The term “vegetable” doesn't exist in botany. It comes from the culinary world and refers to plants with low sugar content that are used in savory dishes.
Compared to a true starch like potatoes, pumpkin has quite a bit less starch. The best category for pumpkin would be among squashes in the cucurbit group.
Pumpkins are a great source of fiber and are loaded with beta carotene. This antioxidant helps support immune health, eye health, and reproductive health.
