Peas: The Humble Green Protein Powerhouse
You might walk past peas in the grocery store, assuming they’re just a side dish, but new research shows peas pack more protein than you’d think. A single cup of cooked green peas contains nearly 8 grams of protein, which is more than an egg. According to USDA data, peas are now being recognized as a key ingredient in plant-based protein powders and even meat alternatives. The fiber content in peas also helps with digestion, making them a double-win for health. In 2024, several food tech companies have invested millions into pea protein for its sustainability and protein punch. This little green veggie is now a global star, thanks to its impressive stats and versatility.
Broccoli: Surprising Protein in Every Floret
Broccoli is often touted for its vitamins, but its protein content is finally getting attention. One cup of chopped broccoli contains about 2.6 grams of protein, which may not sound like much until you consider its low calorie count. According to the Harvard T.H. Chan School of Public Health, the protein-to-calorie ratio in broccoli rivals that of beef when measured per calorie. In recent years, dietitians have recommended broccoli for those looking to boost protein intake without extra fat. Plus, when paired with other plant foods, its amino acids combine for a complete protein profile. Broccoli’s protein power is now a favorite among vegetarians and flexitarians alike.
Quinoa: The Ancient Grain With a Modern Protein Twist
Quinoa isn’t just another trendy grain—it’s a complete protein, meaning it contains all nine essential amino acids. With about 8 grams of protein per cooked cup, quinoa has become a staple for people seeking plant-based protein. The Food and Agriculture Organization named 2013 the “International Year of Quinoa,” and its popularity has only grown since. Recent reports show that quinoa sales hit record highs in 2024, especially among consumers looking for gluten-free, high-protein foods. Its mild, nutty flavor and versatility in salads, bowls, and even breakfast make it a smart pick for protein-conscious eaters. Quinoa’s rise proves that ancient foods can have a modern comeback.

Potatoes are famous for their carbs, but they’re quietly a source of protein too. A medium baked potato with the skin delivers about 4 grams of protein, according to the USDA. In 2025, researchers highlighted potatoes as a protein contributor in plant-based diets, especially when paired with other veggies. While the protein content isn’t sky-high, potatoes are eaten in large enough quantities to make a difference. New plant-based meat products are even using potato protein to improve texture and nutrition. The humble potato is finally getting some respect as more than just a starchy filler.
Spirulina: The Tiny Algae With Big Protein

This blue-green algae contains a staggering 57 grams of protein per 100 grams, according to recent research reviewed in Nutrients journal in 2024. While you’d never eat 100 grams in one go, just a tablespoon gives a meaningful protein boost. Spirulina is also rich in B vitamins and iron, making it a favorite among athletes and vegans. The World Health Organization has even called it a “superfood” for its nutritional profile. Spirulina’s rise is proof that sometimes the smallest foods pack the biggest punch.

Corn’s protein boost might be the most surprising thing about this familiar veggie.
Greek Yogurt: Thick, Creamy, and Packed With Protein
Greek yogurt’s creamy texture is more than just delicious—it’s the result of its ultra-high protein content.
