It is good for us and our dogs. We sometimes make some dog treats out of pumpkins. I don't remember why but my vet had me give a dog or two some canned pumpkin when something was going on. I've read that pumpkins is also a good home remedy t stop dogs from eating their own stool. The dog love the taste going in, but won't like the take after it comes out. I don't know if it works, but there is a lot of things I've found online that says it does.
As far as humans I was taught in several nutrition and biology courses that we should eat a variety of colors when eating fruit and vegetables. Each color has a good source of certain nutrients that we will get from things of that color.
Example:
We know carrots are supposed to be good for the eyes. The nutrient that is great for eyes that is in carrots are in all vegetables that are orange. So instead of trying to figure out what foods to eat to get these vitamins, minerals, and antioxidants we should just plan to eat a variety of color and you will get every nutrient.
