Is Zucchini a Fruit or Vegetable? Nutrition Facts and Health Benefits

Determining if Zucchini is a Fruit or Vegetable

With its mild flavor and culinary versatility, zucchini is a popular type of summer squash. But the exact classification of zucchini causes confusion - is zucchini a fruit or a vegetable?

Defining Fruits and Vegetables

Botanically speaking, a fruit develops from the ovary of a flower and contains the seeds of the plant. A vegetable consists of other edible parts of plants like roots, stems and leaves.

By this definition, zucchinis are technically fruits since they contain seeds and grow from the base of yellow zucchini flowers on vines.

Why Zucchini is Considered a Vegetable

Though a botanical fruit, zucchini is typically prepared and eaten as a veggie-like food:

• It has a neutral, non-sweet flavor profile unlike most fruits
• Zucchini is prepared and served as part of savory dishes
• It shares a similar nutritional profile with vegetables

For these reasons, zucchini is usually grouped under the vegetable food group in culinary and dietary contexts.

Zucchini Nutrition Facts

Like all summer squash varieties, zucchini offers a range of important vitamins, minerals and beneficial plant compounds with few calories per serving.

One raw zucchini (196g) provides approximately:

• 33 calories
• 2 grams protein
• 6 grams carbs
• 3 grams sugar
• 2 grams fiber
• 10% DV vitamin C
• 10% DV manganese

Carbs, Fiber and Water Content

A one cup serving of raw zucchini slices contains around 3 grams of digestible carbs and 2 grams of fiber. Zucchini is also 95% water, making it an excellent low-calorie food.

• Vitamin C: supports immune health and collagen synthesis
• Vitamin A: important for eye and skin health
• B Vitamins: aid converter food into energy
• Manganese: assists bone formation and metabolism

Other Plant Compounds

Zucchini also provides beneficial plant compounds like:

• Lutein and Zeaxanthin: antioxidants that promote eye health
• Polyphenols: support reducing inflammation and oxidative stress
• Phytosterols: linked to balanced cholesterol levels

Health Benefits of Zucchini

The rich nutrient and beneficial plant compound content of zucchini is associated with an array of possible health benefits.

Supports Heart Health

Getting enough veggies like zucchini reduces risk of heart disease mortality. Zucchini's fiber, potassium, vitamin C and anti-inflammatory compounds also support cardiovascular health.

Can Help Manage Diabetes

The low starch and sugar content paired with fiber make zucchini a smart choice for diabetics monitoring carbs. Animal studies also show zucchini peel extracts may reduce hyperglycemia.

Aids Healthy Vision

The high lutein, zeaxanthin and vitamin A content in zucchini helps reduce risk of age-related macular degeneration and cataracts - two common causes of vision loss.

May Have Anticancer Effects

Preliminary studies indicate the beneficial plant nutrients in zucchini like polyphenols may help slow cancer cell multiplication for reduced tumor growth and metastasis.

Protects Skin Health

Vitamin C assists collagen production for youthful skin while beta-carotene gets converted into protective vitamin A to maintain skin cell integrity and elasticity.
