Vegetables are colorful, versatile, and full of nutrients vital to health. According to their nutritional content, they are divided into groups such as dark green, starchy, beans, peas and lentils.
Most adults should aim to eat 2-4 cups of vegetables a day, depending on age and gender. Eating vegetables every day can help you get more nutrients from your food. They also help you feel full, making weight management easier.

Spinach
Spinach is one of the most nutrient-rich green leafy vegetables you can eat. It provides significant amounts of vitamins A, B and K. It is a good source of minerals such as manganese, magnesium, iron, copper and calcium. It is also rich in antioxidants, fiber and essential amino acids.
Spinach may help manage blood sugar and cholesterol levels and reduce the risk of some cancers. You may not want to eat spinach every day because doing so can make it harder to absorb calcium and magnesium, which can lead to kidney stones. High amounts of vitamin K may interact with blood thinners and other medications.
carrots
This root vegetable provides plenty of vitamin A. Carrots are a good source of beta carotene, potassium, fiber, antioxidants, vitamin K and essential amino acids.
Phytochemicals in carrots appear to have anti-cancer, antioxidant, anti-inflammatory and antibacterial effects. You’ll get more of the benefits of beta carotene in cooked carrots compared to raw carrots. Consuming many carotene-rich foods for several months can lead to carotenemia, which causes your skin to appear yellow or orange.
sweet potatoes
One medium sweet potato, peeled, provides 122% of the recommended daily value (DV) for vitamin A (based on a 2,000-calorie diet). They are rich in vitamin C, fiber, potassium, B vitamins, beta carotene and essential amino acids, among other nutrients.
Sweet potatoes may help reduce the risk of diabetes, cardiovascular disease and cancer.
Broccoli
Broccoli is rich in fiber and vitamins A, C and K and is a good source of calcium, potassium and iron. Broccoli has powerful antioxidant, anti-inflammatory and anti-cancer properties. Raw or cooked broccoli is a great way to get your greens.
Some research suggests that indole glucosinolate, a compound found in cruciferous vegetables, interferes with thyroid hormones. But there isn’t enough data to tell you how much you need to eat to cause a problem.
Cabbage
Kale is a good source of vitamins K, C, A and B6, folate and manganese. It is also rich in fiber and carotenoids, lutein and zeaxanthin.
The antioxidants in kale help reduce inflammation and oxidative stress. This leafy green herb may help with constipation or digestive problems. It may also protect against heart disease, cancer and obesity. You’ll get more nutritional value from raw kale rather than cooked kale.
green peas
One cup of cooked green peas contains 31% of your daily needs for fiber. You’ll also get plenty of protein and vitamins A, B, and C, as well as iron and other important nutrients.
Green peas and other legumes are low-glycemic index foods, meaning they generally do not raise blood sugar. These vegetables may help reduce the risk of diabetes and heart disease. Additionally, the protein and fiber content of peas can help you feel full and control your appetite.
Tomatoes
Tomato, a fruit, contains plenty of vitamin C and other antioxidants. Tomatoes may help reduce the risk of heart, neurodegenerative and intestinal diseases. And tomatoes are good for the immune system and skin.
Known for its abundance of lycopene, which has anti-cancer properties, tomatoes are nutritious in raw or cooked form. However, it is easier for the body to absorb lycopene from cooked tomatoes rather than raw ones.
brussels sprouts
One serving of Brussels sprouts contains about half your daily requirement for vitamin C along with other antioxidants. You’ll also get plenty of fiber, potassium and folate. This cruciferous vegetable supports blood and bone health, supports the immune system, and may help prevent some cancers. They help you feel full but are low in calories. If you boil Brussels sprouts, you’ll lose some vitamin C, so you may want to steam, fry, or sauté them.
Pepper
Bell peppers are fruits, but most people use them as vegetables. They come in a variety of colors including green, yellow, orange and red. Although their nutritional value varies slightly depending on color, they are all nutrient-dense.
Pepper is rich in bioactive compounds that have antioxidant, antibacterial, antifungal, anti-diabetic and anti-tumor properties. They are also beneficial for the immune system.
onions
Bioactive compounds in onions provide many health benefits. They have antioxidant, antimicrobial and anti-inflammatory effects. They may also protect against diabetes, cancer and heart disease. They are also beneficial for the digestive, immune and reproductive systems.
Garlic
Garlic owes many of its health benefits, including its powerful antioxidant properties, to a number of bioactive compounds. Garlic may help improve cholesterol and blood pressure. Its anti-inflammatory effects may help reduce the risk of chronic diseases such as cancer, diabetes and cardiovascular disease.
Swiss Chard
Swiss chard is a good source of vitamins A and C. Swiss chard and other leafy greens contain plenty of antioxidants that may help reduce the risk of heart disease and some cancers. It also contains fiber, which can help with weight control and digestion.
One cup of raw chard contains 249% of your daily requirement for vitamin K. Vitamin K is important for bone health and blood clotting. However, it may interact with blood thinners and other medications.
Beet
Beets are full of fiber and rich in vitamins A, B, C and K, as well as folate, nitrates and antioxidants. This root vegetable may help reduce the risk of chronic diseases such as cardiovascular disease and cancer. Beets may also help protect against memory loss and dementia.
Asparagus
Asparagus is high in vitamins A, C, E, K and B6. It is also rich in folate, iron, copper, calcium, protein and fibre. It’s low in fat and calories but helps you feel full, which can help with weight management. Asparagus is good for blood and bone health and has cancer-fighting properties.

kale
Kale is a nutritional powerhouse that provides 27% of your daily needs in fiber and 21% in calcium. It’s also high in vitamins A and C and beta carotene, and also provides 644% of your DV for vitamin K.
Vitamin K is good for your bones and helps blood clot. Too much vitamin K is rarely harmful, but it may interact with some medications. Leafy green vegetables, such as kale and cabbage, are good for brain health and may help slow cognitive decline as we age.
Cauliflower
Cauliflower provides large amounts of vitamins and minerals, including vitamins C and K, as well as folate, phosphorus and B vitamins. Cruciferous vegetables are low in calories and high in fiber, so they help you feel full. Eating them regularly is associated with a reduced risk of some cancers, depression, and all-cause death.
When cauliflower is boiled, it loses some of its nutritional value. You will get more health benefits when consumed raw, steamed, stir-fried or microwaved.
Red cabbage
One cup of red cabbage provides more than half of your daily requirement for vitamin C and 28% of your daily requirement for vitamin K. It also contains high amounts of fibre, iron and potassium. This reddish-purple color indicates that red cabbage contains anthocyanins, which are linked to a lower risk of cardiovascular disease.
Research suggests that glucosinolates and their isothiocyanate metabolites in cruciferous vegetables may help prevent some chronic diseases.
seaweed
The nutritional value of seaweed varies depending on its type. In general, seaweed is loaded with minerals. It is high in fiber and supports intestinal health. Seaweed also contains polyphenols, carotenoids and omega-3 fatty acids that help prevent diseases.
Fermented Vegetables
Depending on the vegetable, fermentation can increase or decrease certain nutrients. Either way, fermented vegetables are rich in probiotic bacteria and may help speed up metabolism and reduce the risk of obesity, gastrointestinal diseases, and chronic diseases. Fermented foods often have a high salt content, so moderation is key.
Summary
A healthy, balanced diet is rich in vegetables and fruits. When it comes to vegetables, some are more nutrient dense than others. Each provides a unique blend of healthy properties. You will gain more health benefits by diversifying your vegetables according to their color, texture and flavor at each meal.
