Registered dietitian Amber Sommer, RDN, LD, gives the 411 on the many health benefits of squash, along with how to make them a delicious addition to your diet.

The health benefits of eating squash

Contrary to popular belief, squash is botanically classified as a fruit, not a vegetable. This is because it grows from flowers and has seeds. But squash brings the best of both produce worlds when it comes to health benefits. “They’re all relatively low in carbs, high in fiber and nutrient-dense,” says Sommer.

For example, winter and summer squash are low in calories and fat, and both are excellent sources of vitamin C. They also contain fiber, B vitamins and important minerals such as potassium and magnesium.

Sommer explains how these antioxidants, minerals and vitamins in squash benefit your health.

Prevents chronic diseases

Squash contains antioxidants, which prevent cellular damage caused by free radicals. Antioxidants are a nutritional jackpot for your body — no risk and all reward.

“Your body creates free radicals naturally as it converts food into energy or in response to environmental factors like pollution. Free radicals are missing an electron, so they’re constantly looking to steal them from other cells,” explains Sommer.

“Too many free radicals create oxidative stress. Over time, oxidative stress causes cell damage and lays the foundation for disease development. But antioxidants fight free radicals, preventing this damage and staving off chronic ailments like cancer and heart disease.”

Beta-carotene is an antioxidant found in squash. Your body transforms beta-carotene into the essential nutrient vitamin A. Studies have also linked beta-carotene to a lower risk of cancers, including:

Helps maintain bone health

Squash is rich in minerals, including calcium. Calcium helps build and maintain healthy bones and teeth. The vitamins A and C in squash also help keep your bones healthy. In fact, a 2017 review of studies linked vitamin A deficiency to an increased risk of bone fractures.

Keeps blood healthy

Squash is a great source of iron. Iron deficiency can cause a host of problems, including anemia. Getting enough iron doesn’t just help prevent and treat anemia. “Research also shows that iron has benefits during menstruation, such as reducing fatigue and improving athletic performance,” notes Sommer.

Supports heart health and function

Squash contains magnesium, which is essential for more than 300 processes in your body. “Magnesium maintains your heart rhythm and helps make DNA. It can also help you stay energized,” says Sommer.

Potassium-rich foods like squash also help your body function by supporting your heart and can help lower blood pressure. “And research has linked the beta-carotene in squash with heart disease prevention,” she adds.

Protects eye health

Squash is a smorgasbord of powerhouse vitamins, including vitamins A and C. Studies show that vitamin A can help protect your eyes and plays a role in preventing night blindness and age-related macular degeneration.

In addition to being an immune health superhero and powerful antioxidant, vitamin C helps your eyes, too. Like vitamin A, it prevents and slows macular degeneration and may also help prevent cataracts.

Keeps skin healthy

Studies show that vitamin C and beta-carotene are good for skin health. Vitamin C is also connected with wrinkle prevention and wound healing.

How much squash should you eat?

Despite being #teamfruit, the U.S. Department of Agriculture (USDA) lumps squash in with veggies based on their nutrition content. According to MyPlate, the USDA’s nutrition guide for Americans, you should aim for two to four servings of vegetables daily. Where you fall in that range depends on your sex, age, activity level, height and weight. The USDA considers 1 cup of cubed, sliced or diced winter or summer squash to be one serving of vegetables.

“Nutritionally, butternut and acorn squash are arguably the overall MVPs, but it’s by the slimmest, most subjective of margins,” says Sommer. “However, don’t worry about choosing the healthiest squash. Instead, choose the ones that taste best to you and try to eat a variety to get the most benefit from eating squash.”

Try summer squash raw or spiraled into “zoodles” as a healthy substitution for noodles. They’re also yummy sautéed or roasted with olive oil. Winter squash is delicious (and sugary sweet like a sweet potato) when roasted. And both are great additions to soups and pastas.

Whether you add it to your favorite recipe or eat squash on its own, your body will thank you.
