Kabocha Squash Health Benefits

Kabocha is low in calories and high in fiber and important vitamins. Let’s now understand how all this can help benefit our health.

Lowers Cancer Risk

The cucurbitacins found in the winter squash and Cucurbitaceae family have also been found to be instrumental in preventing the development of certain cancers (2). Beta-carotene is a phytochemical found in kabocha squash. It gets converted to vitamin A in the body and might help prevent the risk of certain cancers (3). Moreover, vitamin C found in kabocha squash might also be helpful in preventing cancer (4). However, more human studies are warranted to validate these cancer-fighting claims.

Supports Eye Health

The beta-carotene and vitamin C found, in kabocha have been shown to be effective in slowing down AMD (age-related macular degeneration) (1),(5). Additionally, people with a regular intake of vitamin C from food might have a lower risk of developing cataracts in their eyes (6).

May Help Skin Care

Kabocha squash may also help clear your complexion by reducing scars and blemishes. The beta-carotene and various other antioxidants found in kabocha help reduce oxidative stress and inflammation in the skin and prevent signs of aging (7), (8).

Aids In Digestion

The dietary fiber in kabocha, especially in the outer edible rind, can provide multiple digestive benefits. When cooked and consumed, the outer rind can potentially help improve digestion, regularize bowel movements, and reduce bloating and other symptoms of constipation (9).

Adverse Effects And Risks Of Kabocha Squash

Pumpkins, squashes, and other members of the Cucurbita family can produce certain toxic substances called cucurbitacins. These have a bitter taste and can cause severe diarrhea even when taken in small amounts (10). An excessive intake of kabocha squash or any other fruit or vegetable containing beta carotene can develop a condition called carotenemia (11). This causes your skin to appear yellowish or orange in color. It is important to note that carotenemia is harmless and can resolve on its own once you cut back on the intake of carotene-rich foods. Winter squash or kabocha allergies are very rare and not commonly heard of. In case you suspect an allergic reaction after consuming kabocha, you should consult your doctor.

Storage And Food Safety

Kabocha squash, being winter squash, is usually grown in the warm season and is available from October to January.

When buying a kabocha, it is better to buy it from your local farmer’s market to avail it freshly harvested. Choose an average-sized kabocha with hard, thick skins and dry and intact stems. You should avoid any kabocha with soft or rotten stems, soft blemished spots, cuts, or damaged in other ways. Whole kabocha can be stored for 2-4 months at home in a cool and dry place. Cut portions of kabocha should be used as soon as possible. They can otherwise be wrapped in plastic film or kept in a ziplock bag stored in the fridge for 1-2 days maximum before use. You can also keep cooked squash in the freezer, where it will last for up to a year.
