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

What Type of Plant is Zucchini?

Zucchini is part of the Cucurbitaceae family, which also includes cucumbers, various kinds of melons, pumpkins, and squash. Many people mistakenly think zucchini is a vegetable, but it is actually a fruit.

Botanically speaking, zucchini is classified as a fruit because it contains seeds and develops from the ovary of a flowering plant. However, in culinary terms, zucchini is typically prepared and eaten as a vegetable.

Zucchini Plant and Growth

The zucchini plant is a warm weather, frost sensitive annual that thrives in temperate climates. It has large prickly leaves and yellow flowers that bloom in the early summer months.

After pollination, the female zucchini flower develops into the familiar green fruit or vegetable that we know as a zucchini. The fruit hangs from the vine in an immature state and can grow quite rapidly under the right conditions.

Zucchinis are best harvested young, when they are still small and tender, usually about 6-8 inches long. If left on the vine too long, zucchinis will develop tough skin and large seeds making them less palatable.

When is Zucchini in Season?

In the United States, zucchini is in peak season during the summer months of June, July and August. However, modern greenhouse farming techniques have made it possible to get zucchini year round in most grocery stores.

For the best flavor and texture, it's still ideal to enjoy zucchini during the summer when it is at its seasonal best.

Nutrition Facts and Health Benefits

Zucchini is an extremely healthy and nutritious vegetable that provides a wide array of vitamins, minerals and antioxidants.

Low in Calories

One of the best things about zucchini is its low calorie content. A 1 cup serving of raw zucchini contains only about 20 calories, with 4 grams of carbohydrates and 2 grams of protein.

This makes zucchini an excellent food for managing weight and diabetes. It can help fill you up without significantly increasing calorie intake.

High Water Content

Zucchini has a very high water percentage, around 95%. This means that zucchinis are low in calories and rich in hydrating water content.

Eating foods with high water content, like zucchini, can help with overall health by promoting proper hydration and bowel regularity.

Excellent Source of Vitamin C

One cup of raw zucchini provides over 35% of the RDI for vitamin C. Vitamin C is an essential nutrient that acts as a powerful antioxidant in the body.

Getting enough vitamin C daily can help boost immunity, reduce illness, improve eye health, lower heart disease risk and prevent muscle soreness after exercise.

Good Source of Vitamin K

Zucchini provides around 15% of the RDI for vitamin K in each 1 cup serving. Vitamin K plays key roles in blood clotting and bone health.

Adequate intake of foods containing vitamin K, like zucchini, reduces fracture rates and improves bone mineral density.

Rich in Antioxidants

In addition to vitamins C and K, zucchini contains beneficial antioxidants such as lutein, beta-carotene, zeaxanthin, and others. These compounds fight free radical damage in the body and lower oxidative stress.

Eating plenty of antioxidant foods like zucchini can help prevent common diseases associated with aging including cancer, heart disease, and arthritis.

Good for Heart Health

Several nutrients found in zucchini like potassium, folate and vitamin C support heart health. These nutrients help lower blood pressure, regulate circulation, and prevent plaque buildup in arteries.

The high water and fiber content in zucchini is also beneficial for cardiovascular health. Overall, adding zucchini to your diet can help reduce risk of stroke and heart disease.

May Help Manage Diabetes

Zucchini is a smart choice for those looking to control blood sugar levels. It has a very low score on the glycemic index, meaning it doesn't cause large blood sugar spikes after eating.

The low carb, high water and fiber content of zucchini helps slow digestion and regulate the release of glucose into the bloodstream. This effect of zucchini makes it an excellent food for diabetics.
