Your guide to the healthiest veggies: These are the best types to add to your diet
Are you eating your greens? Chances are, even if you get some veggies, you’re not consuming nearly enough. In 2019, the Centers for Disease Control and Prevention found that only 10% of Americans are meeting their daily vegetable intake.
But it's never too late to make a change.
We’ve reported on the healthiest type of lettuce, the most nutritious potato options and the bell pepper with the most antioxidants, but what reigns supreme when you look at the vegetables as a food group? Here are the best greens to include for health benefits.
Healthiest vegetables to include in your diet
Any vegetable will provide essential nutrients, so “don’t discriminate,” registered dietitian Danielle Crumble Smith previously told USA TODAY. But if you’re looking to increase your vegetable intake and diversify your options, here are some of the best varieties.
Darker leafy greens are rich in many vitamins, including vitamins K and C, calcium and a host of antioxidants, Crumble Smith says.
Vitamin K has cardiovascular and bone health benefits and vitamin C helps protect blood cells against disease and aids in the absorption and storage of iron. Calcium supports healthy bones, teeth, muscles, hormone production and other bodily functions. Spinach and kale also contain lutein and zeaxanthin, two antioxidants that benefit eye health.
Here are the best leafy green vegetables to include in your diet, according to Crumble Smith:
Spinach
Chard
Collard greens
Mustard greens
Beet greens
Cruciferous vegetables make a great addition to your diet because they contain fiber and phytonutrients, which help prevent cellular damage. They also contain indole-3-carbinol, a compound shown to reduce the risks of estrogen-related cancers as well as colon cancer, Crumble Smith says.
Cruciferous vegetables are also rich in folate, a water-soluble nutrient that benefits the digestive system and may prevent common cancers, cardiovascular disease, infertility, stroke, dementia and Alzheimer’s disease. They also contain vitamin K and the dark green ones contain vitamins A and C, according to the Academy of Nutrition and Dietetics.
Try adding these cruciferous veggies to your daily vegetable intake, Crumble Smith advises:
Broccoli
Kale
Cauliflower
Brussel sprouts
Asparagus
Cabbage
Bok choy
Why are vegetables good for you?
Eating a variety of vegetables ensures your body is getting the vitamins and nutrients it needs for daily function., This is especially crucial for ones Americans don’t get enough of, like fiber and potassium. Fruit and vegetable intake is associated with a lower risk of cardiovascular disease, cancer and mortality, studies show.
Even frozen vegetables are a healthy option. They may even offer more nutrients than those bought at your local grocer because you don’t know how long it’s been since their harvest date, Crumble Smith previously told USA TODAY.
"They’re flash frozen at their peak stage of ripeness when all those nutrients are there and preserved," she said. "Frozen veggies are a great, very nutrient-dense option and they’re also really good for people who forget there are veggies in the fridge that might be going bad before they get to it."
How many servings of vegetables per day?
The U.S. Department of Agriculture recommends 2 to 3 cups of vegetables per day for adult women and 3 to 4 cups for adult men. Here are a few examples of what counts as "one cup" of vegetables:
One cup of cooked dark green vegetables
One cup of broccoli (fresh or frozen)
Two cups of fresh raw leafy greens
Two medium carrots or one cup of baby carrots
One large bell pepper
One large baked sweet potato or one cup mashed or sliced
One avocado
