Celebrate Summer with Zucchini

Many people think of zucchini as a vegetable but it is actually considered a fruit. Zucchini is a member of the Cucurbitaceae family and a close relative to melon and cucumber. This family also includes all squashes and gourds.

Also known as courgette or just referred to as summer squash, it is a type of summer squash that varies in color from yellow to dark green. Zucchini is tender, has a mild flavor, and can easily be incorporated into entrees and side dishes.

Nutrients in a Zucchini

Zucchini is an excellent source of vitamins and minerals, especially copper and manganese. It contains 19% of the RDA of manganese, which is essential in metabolizing proteins and carbohydrates. It is also a good source of phosphorus, folate, and vitamins A, B6, C, and K. Additionally, the magnesium and potassium in zucchini are important in blood pressure regulation.

Zucchini has very high water content and contains only 20 calories per cup, making it a perfect combination for weight management. Not to mention, it is a good source of dietary fiber, containing 2.5 grams of fiber per cup. It’s polysaccharide fibers, known as pectin, are helpful in regulating insulin and blood sugar levels.

Additional Health Benefits

Eye Health

Zucchini contains the carotenoids, lutein and zeaxanthin, which function as antioxidants and play a role in maintaining optimal eye health. Lutein and zeaxanthin have been shown to reduce the risk of chronic eye diseases such as age related macular degeneration and cataracts.

Heart Health

Folate, as found in zucchini, is important in lowering homocysteine levels in the body. Homocysteine promotes atherosclerosis by damaging blood vessels and causing blood clots. It is believed that elevated homocysteine levels are related to a higher risk of coronary heart disease.

Prostate Health

Phytonutrients in zucchini are thought to reduce the symptoms of benign prostatic hypertrophy, a condition that is characterized by increased urinary frequency and an enlarged prostate gland.

Picking the best Zucchini

Zucchini is abundant during the late spring and summer months and although it is a summer squash, it’s actually available all year round. When purchasing, look for ones that have a soft and unblemished rind. You can store zucchini unwashed in an airtight container in the refrigerator for up to 7 days.

Zucchini can be eaten raw or cooked, but steaming is considered the best way to retain its antioxidants and prevent nutrient loss.

Below is one of my staple zucchini recipes that I use frequently during the warmer months. It’s light yet nutrient-rich and perfectly satisfying. Enjoy!
