Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Butternut squash is used to support eye health primarily due to its high content of carotenoids, particularly beta-carotene and lutein. Beta-carotene is a precursor to vitamin A, an essential nutrient for maintaining healthy vision. Vitamin A deficiency is a well-known cause of night blindness and other ocular problems. Butternut squash provides a significant amount of beta-carotene, which the body can convert into vitamin A as needed. Additionally, lutein, another carotenoid present in butternut squash, is known to accumulate in the retina and has been associated with a reduced risk of age-related macular degeneration (AMD).

Several observational studies have linked higher intakes of carotenoid-rich foods, including those like butternut squash, with a lower risk of certain eye conditions such as cataracts and AMD. However, most of the direct clinical evidence relates to carotenoids in general, not specifically to butternut squash. The scientific support is thus moderate, as it is based on the presence of compounds in the food and extrapolation from studies using supplements or other carotenoid-rich foods. Nevertheless, the inclusion of butternut squash in a balanced diet can contribute beneficial nutrients for overall eye health.
