Unlike potatoes, squash and beans, non-starchy vegetables are low in both carbohydrates and calories, making them a particularly healthy addition to your diet.
Veggies that are low in starch (a type of carb) are also high in fiber (another type of carb), which is a nutrient that can help promote healthy digestion, lower cholesterol, control blood sugar and help promote healthy weight management, according to the Mayo Clinic.
"But since no single vegetable contains every single nutrient, eating a variety can provide an array of nutrients that can help reduce the risk of chronic conditions such as diabetes, heart disease, high blood pressure and stroke," Dr. Harry says.

The Health Benefits of Non-Starchy Vegetables
1. They're Linked to Promoting Healthy Brain Function
Non-starchy vegetables, especially leafy greens, are high in folic acid (aka folate), a B vitamin that helps promote healthy brain development and function, according to Dr. Harry. These veggies are also high in vitamin K and phylloquinone, which may also promote cognitive performance, according to a March 2019 study published in Frontiers in Neurology.
After observing a group of 960 people aged 58 to 99 years old for about five years, researchers found that eating one serving of leafy vegetables each day is linked to helping slow cognitive decline, per a January 2018 study published in Neurology.
2. They're Tied to Good Heart Health
Increasing your daily intake of non-starchy vegetables can also protect your ticker. Even replacing some of the starchy veggies on your plate with some low-starch options is linked to lowering the risk of heart disease, according to a March 2018 study published in Circulation.
After looking at more than 41,000 adults, researchers in the above-mentioned study observed that swapping one daily serving of starchy vegetables with non-starchy veggies resulted in a 21 percent lower risk of coronary heart disease. Researchers also observed that replacing one serving per day of processed or red meat with low-starch vegetables was associated with a 23 percent lower risk of heart disease.
3. Their Low Carb and High Fiber Content Can Help Manage Diabetes
Carbohydrates, especially refined carbs like sugar, are known for spiking blood sugar levels, which can be dangerous for people with diabetes. Reducing carbohydrates, however, can normalize blood sugar levels, helping manage this condition, according to a 2019 study published in Diabetes Management.
Researchers emphasized a diet rich in non-starchy vegetables due to their high fiber content. Fiber is crucial for helping control blood sugar, slowing the body's absorption of carbohydrates, according to the Mayo Clinic. The nutrient has also been associated with a lower risk of developing type 2 diabetes.
4. Vegetables Can Help With Weight Management
Since many low-starchy veggies contain a decent amount of fiber, they could inch you closer to your weight-loss goals. Unlike protein, fats and carbs, fiber goes through your body undigested and passes slowly through the intestines, which can help you feel satiated after a meal, according to the Mayo Clinic.
Eating enough fiber (the FDA recommends about 25 grams per day), can promote weight loss, according to an October 2019 study published in the Journal of Nutrition. After observing 345 adults on a calorie-restricted diet, researchers found that increasing dietary fiber helped participants most closely stick to their eating regimen.
Easy Ways to Add Low-Starchy Veggies to Your Diet
Aim to eat at least three to five servings of vegetables a day — one serving is about a cup of raw veggies, according to Dr. Harry. Keep these tips, courtesy of Dr. Harry, in mind when you're trying to add more of these rockstar veggies to your day:
- Add spinach or kale into your breakfast smoothie is a great way to incorporate leafy greens into your daily routine.
- Sauté them with a little olive oil and garlic to make them more appealing and pair with your favorite protein and carb.
- Get creative with dips, blending beets, olive oil, roasted garlic, Greek yogurt and fresh herbs.
