The 21 Most Healthy Vegetables To Eat
1. Sweet Potatoes
Sweet potatoes, with their natural sweetness and vibrant color, are a fall produce favorite and are among the healthiest vegetables, thanks to their antioxidant properties. Rich in beta-carotene (which the body converts into vitamin A) and fiber, they support eye health and digestion.
To avoid blood sugar spikes caused by the high glycemic index of sweet potatoes, pair them with protein or healthy fats. Whether baked, mashed or fried, their flavor is a hit in dishes like baked candied sweet potatoes or sweet potato cornbread.
Cooking also enhances the nutritional benefits of the healthiest vegetables like sweet potatoes, making them a deliciously nutritious choice — but be careful, because overcooking can reduce levels of water-soluble vitamins like vitamin C.
2. Collard Greens
Part of the family of cruciferous vegetables, collard greens contain a rich supply of vitamins A, C and K as well as calcium and are among the healthiest vegetables to eat for supporting bone health.
Do note that collard greens contain oxalates, which can contribute to kidney stones and interfere with blood-thinning medications but issues like these are less common in people with balanced diets who stay well-hydrated. Cooking them also reduces their oxalate levels and pairing them with calcium-rich foods enhances nutrient absorption.
Whether sautéed, steamed or included in dishes like Instant Pot collard greens, Kenya’s sukuma wiki or Brazil’s caldo verde soup, these greens are a nutritious addition to any meal and firmly among the healthiest vegetables available.
3. Brussels Sprouts
Brussels sprouts, small cruciferous vegetables resembling miniature cabbages, are packed with nutrients, making them some of the healthiest vegetables to include in your diet. They shine as one of the healthiest vegetables thanks to their rich content of vitamins C and K and high amounts of fiber.
Brussels sprouts also contain kaempferol, an antioxidant that supports heart health and reduces inflammation. Their high fiber content, however, can lead to gas or bloating, but gradually increasing intake and cooking them thoroughly can mitigate this effect. Steamed or roasted, they work great in many tasty dishes like sautéed Brussels sprouts or Brussels sprouts and bacon.
4. Bell Peppers
Bell peppers, with their vibrant color and sweet flavor, are a staple in many global cuisines and also make excellent healthy snacks. Rich in vitamins A and C, they are among the healthiest vegetables for supporting eye health and providing antioxidants like beta-carotene and lycopene.
The red color signifies a well-ripened bell pepper that will be sweet and green or yellow signifies less mature bell peppers that may be more bitter. Also, note that some people may experience mild allergic reactions or digestive discomfort when eating bell peppers. However, cooking peppers may alleviate these issues.
Whether eaten raw in salads or cooked in dishes like pisto manchego or keto stuffed bell peppers, these versatile vegetables add both nutrition and flavor to any meal.
5. Spinach
A highly versatile leafy green, spinach is one of the healthiest vegetables to include in your diet when considering how to start eating healthy. It’s packed with iron, calcium and vitamins A and C. Spinach also supports eye health and may lower blood pressure, thanks to its nitrate content.
However, its high oxalate levels can hinder calcium and iron absorption and contribute to kidney stones in people who are susceptible to them. Lightly cooking spinach significantly reduces oxalates and enhances iron bioavailability when paired with vitamin C-rich foods.
Spinach shines when cooked in dishes from India, such as saag paneer or vegan tikka masala and it can be eaten raw in salads as well.
6. Kale
Kale, a nutrient-dense member of the cabbage family, is a quintessential superfood and a strong contender among the healthiest vegetables. With its abundance of vitamins A, C and K and powerful antioxidants, kale can lower cholesterol and support heart health.
Kale’s versatility makes it a popular choice in raw salads, smoothies or baked as chips. It also stars in healthy recipes like white bean and kale soup or a Mediterranean-style lemon kale salad. With so many nutrients and just as many ways to include it in your diet, kale is certainly one to consider when determining the healthiest vegetable of them all!
7. Broccoli
Broccoli, recognized for its tree-like structure, is a standout among the most nutritious vegetables and is rich in vitamins C and K as well as fiber. The vegetable's strong nutritional profile and versatility make it a top choice when deciding on the healthiest vegetables to add to your daily meals.
Its high fiber content may mean you want to add it slowly to your diet if you're not used to foods high in fiber. Cooking broccoli also helps make it more digestible if this is of concern.
Steaming is the best method for nutrient preservation but raw consumption is a healthy way to eat it too. Broccoli also works great in many more complex recipes, adding flavor and nutrition to dishes like keto broccoli casserole or stir-fried shrimp and broccoli.
8. Watercress
A leafy green aquatic plant, watercress boasts a distinct peppery flavor and an impressive nutritional profile, ranking among the healthiest vegetables for its heart-health benefits.
Packed with vitamins A, C and K, it’s a powerhouse of antioxidants. However, its high vitamin K content can interfere with blood-thinning medications, so it’s always best to consult with your healthcare provider if concerned.
Best enjoyed raw in salads or blended into smoothies, you’ll also find it in traditional dishes like watercress soup from Vietnam and Chinese watercress salad.
9. Cauliflower
Cauliflower often serves as a low-carb substitute for grains and is one of the healthiest vegetables for keto or other low-carb diets. It is packed with vitamins C and K and contains detoxifying compounds.
Cauliflower’s high fiber content can cause bloating but cooking helps reduce these effects while making it easier to digest. Whether roasted or blitzed, it’s a staple in dishes like Spanish cauliflower rice or a hearty cauliflower au gratin, among many others.
10. Carrots
Celebrated for their high beta-carotene content, carrots are undoubtedly one of the healthiest vegetables to eat for maintaining eye and skin health. While excessive consumption can cause carotenemia, moderation balances its benefits.
Cooking carrots enhances beta-carotene absorption but may lower some water-soluble vitamins slightly, keeping them among the healthiest vegetables regardless of preparation.
Popular in dishes like Indian carrot halwa or Moroccan carrot salad, they’re equally delicious raw, roasted or blended into soups.
11. Beets
Known for their earthy flavor and deep red hue, beets are among the healthiest vegetables for supporting liver function and lowering blood pressure, thanks to their nitrate content.
However, their high oxalate levels may contribute to kidney stones, so moderation is key. Cooking enhances their natural sweetness and makes them a comforting addition to dishes like Eastern European borscht or Mediterranean beet salad with feta.
Whether pickled, juiced or baked in dishes like roasted beets and carrots, they are a colorful and nutritious addition to any diet.
12. Asparagus
Asparagus earns its place among the healthiest vegetables for its tender texture, unique flavor and exceptional nutritional profile. Packed with folate and vitamins A, C, E and K, this springtime favorite supports overall health, particularly by aiding digestion through its fiber content and acting as a natural diuretic.
Despite the unfortunate side effect of causing an odor in urine due to asparagusic acid, this is harmless and cooking methods like steaming or grilling can help manage its intensity. Air-fryer asparagus with hollandaise sauce or Italian-style asparagus wrapped in prosciutto showcases the vegetable's culinary adaptability while cooking enhances digestibility.
13. Green Peas
Sweet and tender, green peas are more than just a simple side dish — they're one of the healthiest vegetables thanks to their high protein content and a wealth of vitamins A, C and K.
Although their richness in fiber can cause digestion issues, introducing green peas gradually into your diet and cooking them thoroughly can ease digestion. They are also higher in natural sugars than some other vegetables, so enjoy them in moderation.
Light steaming or boiling retains their vibrant color and nutrients. Traditional recipes like a pea salad, French pea soup or classic mushy peas from the U.K. bring out their best qualities and showcase how versatile these little green veggies can be.
14. Radishes
Radishes, with their crisp texture and peppery bite, are a standout addition to the roster of healthiest vegetables. Rich in vitamin C and potassium, they support digestion and help combat inflammation.
While some individuals might experience digestive discomfort from eating radishes raw, cooking or pairing them with digestion-friendly foods can reduce this effect.
Pickled radishes from Mexico or spicy Korean tofu soup with daikon radishes bring out their vibrant flavor, making them a top choice among the healthiest vegetables in global cuisine. Cooking mellows their sharpness, making them a versatile ingredient in both raw and cooked dishes.
15. Cabbage
Cabbage, available in green, purple or white varieties, is one of the healthiest vegetables offering gut-supporting benefits. This cruciferous powerhouse is a nutritional profile brimming with vitamins K and C, along with dietary fiber and it contains glucosinolates, which are compounds that have anti-inflammatory properties.
However, cabbage’s raw form can sometimes cause bloating, which cooking can alleviate. Pickling helps preserve its nutrients, making it ideal for dishes like German sauerkraut or pickled red cabbage. Whether shredded into slaws or slow-cooked into stews, cabbage is as versatile as it is nutritious.
16. Eggplant
Eggplant’s spongy texture and mild flavor have earned it a place in Mediterranean cuisine and among the healthiest vegetables. This nightshade is loaded with fiber and potassium and its antioxidant content may protect brain cells from damage.
Though solanine in eggplant can cause digestive discomfort, thorough cooking neutralizes this compound while enhancing its flavor. Eggplant proves its versatility in dishes from Japanese eggplant with miso to Thai eggplant curry or Middle Eastern baba ghanoush. Its flavor adapts beautifully, taking on rich, smoky or savory notes depending on the preparation.
17. Zucchini
Zucchini, one of a few summer vegetables in the squash family, is celebrated as one of the healthiest vegetables for its vitamin C and potassium content. Known for aiding digestion and combating inflammation, it’s a gentle yet powerful addition to any diet.
While consuming zucchini raw in large amounts may cause minor digestive discomfort, cooking resolves this issue, making it a favorite in dishes like air-fryer zucchini fries and banana zucchini bread. Zucchini’s adaptability extends from spiralizing into noodles to roasting and stuffing, keeping zucchini among the healthiest vegetables for a nutritious and diverse diet.
18. Mushrooms
With their umami-rich flavor and unique antioxidants, mushrooms are some of the most nutritious vegetables available (although technically classified as fungi instead of vegetables) and are a beloved ingredient across global kitchens.
Their fiber and B vitamin content support digestion and energy production, while ergothioneine, a unique antioxidant, helps protect against oxidative stress. To avoid the risks of toxic varieties, stick to cultivated mushrooms or expertly identified wild ones.
Sautéed in wild mushroom risotto or simmered in mushroom ragout, these fungi bring both depth and nutrition. Cooking not only enhances their flavor but also improves their digestibility.
19. Onions
A staple in kitchens worldwide, onions are celebrated as one of the healthiest vegetables for their high fiber and B vitamin content. They contain an antioxidant that supports cardiovascular health and reduces oxidative stress.
Though some may experience digestive discomfort or heartburn from onions, cooking can mellow their pungency and make them easier to digest. Used in a range of recipes, from Instant Pot French onion soup to Indonesian onion sambal, this healthy vegetable can elevate a variety of dishes, whether caramelized, sauteéd or raw.
20. Garlic
Garlic, with its bold aroma and powerful antioxidants, stands out as one of the most flavor-packed healthy vegetables for supporting cardiovascular health. While consuming garlic raw can cause digestive discomfort, cooking tones down its intensity and highlights its sweetness, making it not only one of the healthiest vegetables but also one of the most delicious.
Traditional dishes like Italian aglio e olio or Asian-inspired honey garlic glazed salmon rely on its transformative properties, proving garlic’s essential role in culinary and health traditions alike.
21. Swiss Chard
Known for its vibrant colors and nutrient density, Swiss chard is one of the healthiest vegetables to eat. Packed with fiber and potassium, it offers anti-inflammatory benefits and supports bone health.
Cooking enhances the digestibility of Swiss chard while preserving its wealth of nutrients, making it a must-have for colorful, nutrient-packed meals. Traditional Spanish dishes like estofado de pollo or Swiss chard pie from Greece showcase its culinary range, solidifying its place among the healthiest vegetables.
What Is the Healthiest Vegetable?
Choosing the healthiest vegetables isn't as straightforward as picking a single "superstar." Instead, it depends on what your body needs and the kind of meals you love to prepare.
Some of the healthiest vegetables like carrots and sweet potatoes boast high levels of beta-carotene, while spinach and kale are packed with iron and antioxidants. If you're watching calories — watercress and zucchini are excellent low-calorie options. Need fiber? Brussels sprouts and broccoli can always be relied on.
A great philosophy of nutrition to follow is one that draws inspiration from South Africa's traditional Seven Colors meal, which emphasizes having a rainbow of food on your plate. By focusing on as many different colors as possible, you’re more likely to create meals that are nutritionally balanced. Vibrantly colored vegetables like Swiss chard or beetroot often signal a high nutritional profile, making them well worth including in your diet.
However, diversity is key and each vegetable brings unique benefits to the table. Incorporating variety not only boosts your health but also adds contrasting flavors, excitement and balance to your meals. The Seven Colors philosophy also aligns with eating seasonally, as each season brings its own colorful bounty that ensures freshness, flavor and sustainability on your plate.
