What is Pumpkin?
We're all familiar with pumpkins from carving them for Halloween, but it's probably worth thinking twice before you chuck out all the pumpkin flesh and seeds. Pumpkin contains a variety of vitamins, minerals and plant compounds, including carotenoids, beta-carotene and vitamin E, and its seeds contain zinc and phytosterols.
Carotenoids are naturally occurring plant pigments and include lutein, zeaxanthin and meso-zeaxanthin. Lutein and zeaxanthin are found in pumpkin.
What does the research say about Pumpkin?
Researchers have looked at pumpkin's nutritional value and phytochemical potential, and much of the interest is in our eyes. Lutein and zeaxanthin levels have been measured in everyday foods, both raw and cooked. Together with meso-zeaxanthin, they are found in your macular pigment and have antioxidant activity. Researchers have also studied the antioxidant activity of polysaccharides from pumpkin.
The body converts beta-carotene to vitamin A, and vitamin A contributes to the maintenance of normal vision. It is a component of 'rhodopsin', a pigment in your retina that is very sensitive to light and is responsible for how our vision adapts in the dark. Vitamin E contributes to the protection of cells from oxidative stress. There is a high concentration of fatty acids in the retina, and vitamin E is a fat-soluble antioxidant. Researchers have reviewed vitamin E in relation to the lens and other parts of the eye.
Zinc contributes to the maintenance of normal vision. Pumpkin seed extract has also been clinically studied in men, with researchers looking at the prostate and bladder.
