Protein is a key component of a healthy diet, and while you can certainly get protein from meats, cheeses, and other food items, some of the best protein sources are vegetables. In addition to being easier on your wallet, these veggies (many of which can actually be grown at home, if you're feeling ambitious) tend to be loaded with other nutrients, which some of those other foods may lack.

The Dietary Reference Intake for protein amounts to 56 grams per day for the average sedentary man, and 46 grams per day for the average sedentary woman. If you suspect you're not getting quite enough protein each day, adding veggies to your diet is a nutritious and easy way to boost your protein intake.

"Protein is a crucial part of a healthy, balanced diet. It's needed to keep cells in the body healthy—it builds and repairs them, as well as tissues, muscles, skin, hair, and bones. Protein is also needed to make enzymes and hormones, maintain proper fluid balance, and the body's acid-base balance—which is critical to the body's survival," say sisters Tammy Lakatos Shames, RD, CDN, CFT, and Lyssie Lakatos, RD, CDN, CFT—aka The Nutrition Twins. "Foods with protein help you to feel satisfied and to prevent overeating. If you don't get enough protein, you'll have trouble maintaining lean muscle mass and you may find yourself hungry often."

High Protein Vegetables

Given the importance of protein, we consulted the U.S. Department OF Agriculture (USDA), and decided to profile some of the most protein-dense vegetables around. Additionally, alongside each veggie you'll find a recipe that uses it, making it even easier for you to get your fill of this critical nutrient. Keep reading to find out which veggies you should stock up on!

"Just a half cup of cooked asparagus provides a whopping 57 percent of the recommended daily intake for vitamin K—a critical nutrient for bone health that tends to get overlooked. That half cup serving also provides 34 percent of the RDI for folate, a nutrient which is essential for cell growth and DNA formation, and one that's critical for a healthy pregnancy," the Lakatos sisters share. "And if you're looking to improve your digestive health, asparagus is your ticket. It contains inulin, a prebiotic fiber that feeds healthy gut bacteria and positively impacts gut health."

"Brussels sprouts are a great source of heart protective folate and fiber."

Protein, per large potato with skin (baked): 3.62 grams

Though not as high in protein as Russet potatoes, sweet potatoes still pack an impressive protein punch. Enjoy them as a side or solo, but remember to eat the skin if you want to soak up all that protein. This recipe also includes feta cheese, which is another solid source of the muscle-building nutrient.

"Sweet potatoes are one of the best mood-boosting foods there are, as they produce endorphins like mood-boosting serotonin. Sweet potatoes also have fiber, so the energy from the carbs enters your bloodstream more gradually, helping to keep your energy levels stable and preventing mood swings that come with energy highs and lows," the Lakatos sisters explain. "They're a rich source of vitamin B6, which is also important to create serotonin. Packed with disease-preventing phytonutrients, sweet potatoes are an excellent source of carotenoids, which fight everything from the negative consequences that come with aging to almost all types of disease."

"Kale has a slew of defense tactics to keep your body free from damage. It is 85 percent water and potassium-packed—a brilliant combo to help restore normal fluid balance while rinsing out bloating salt. Kale is an excellent source of bone-healthy vitamin K, as well as vitamins A and C, and the veggie is a very good source of fiber, potassium, B6, and calcium."
