Eggs have earned their reputation as a go-to protein source, and for good reason. Eggs provide about 6–7g of protein per egg depending on size, which works out to roughly 12.5g per 100g. That’s a solid number, but it’s far from the ceiling. Plenty of whole foods quietly beat that figure by a wide margin, and most of them never get a mention in the typical “high-protein foods” conversation. These six deserve a much bigger spotlight.
1. Tempeh
Tempeh is a fermented soy product that’s a popular vegetarian meat replacement, and whether you’re vegetarian or not, it can be a nutritious addition to your diet. Per 100 grams, tempeh delivers around 20 grams of protein, which puts it well ahead of the egg’s 12.5g benchmark. Because it’s more compact than other soy products, tempeh provides more protein than some other vegetarian alternatives – for example, 100 grams of tofu contains 17 grams of protein, which is about 85% of what the same amount of tempeh provides.
Tempeh is nutrient-rich, providing protein, vitamins, and minerals while being low in sodium and carbohydrates, and its prebiotics may support gut health, while its soy isoflavones may help lower cholesterol and reduce oxidative stress. Tempeh production also has a lower environmental impact compared to many animal-based protein sources – it requires less water, land, and energy to produce than meat or dairy products, and generates fewer greenhouse gas emissions. It’s a compelling option on nearly every front, from nutrition to sustainability.
2. Pumpkin Seeds
Pumpkin seeds are the kind of food that most people toss onto a salad without a second thought, but the numbers behind them are genuinely impressive. They’re loaded with roughly 29.8g of protein per 100g, and they also provide magnesium and zinc, which are vital for energy production and muscle function. The seeds are also an excellent source of the amino acid tryptophan, which is converted into serotonin – a neurochemical often described as nature’s sleeping pill.
The zinc, phosphorus, magnesium, potassium, and selenium found in pumpkin seeds make them a nutritional powerhouse and a potential weapon in the battle against conditions including arthritis, inflammation, and prostate issues. Pumpkin seeds are especially rich in monounsaturated fatty acids like oleic acid, which help lower bad LDL cholesterol and boost good HDL cholesterol, and research suggests that diets liberal in monounsaturated fatty acids contribute to preventing coronary artery disease and stroke. A small handful packs a serious punch.
3. Spirulina
Spirulina remains one of the most underused protein sources in everyday diets, despite a protein content that’s almost difficult to believe. According to USDA findings, 100g of dried spirulina contains 57g of protein, and its roughly 60% protein content has been widely celebrated as a solution for those who struggle to maintain a healthy protein intake. It is one of the few plant-based protein sources that contains about 70% protein by dry weight and has the complete essential amino acid distribution required of a full protein.
A study by the University of Exeter exploring algae-derived proteins from spirulina and chlorella found that they work as great alternatives to animal proteins and are particularly efficient in maintaining and building muscle, making spirulina a strong companion to exercise recovery. Of course, spirulina is consumed in much smaller quantities than whole foods, typically as a powder or tablet. Still, even a tablespoon stirred into a smoothie adds meaningful protein without any real effort. Its nutritional density per gram is simply hard to compete with.
4. Hemp Seeds
Hemp seeds have been quietly gaining ground in the health food world, and the research backing them is increasingly solid. Hemp seeds are rich in protein at 21–32%, and have been compared to legumes such as lentils or beans, surpassing wheat nutritionally. Three tablespoons of hemp seeds provide about 10 grams of protein, and they are a complete plant protein, meaning they contain all nine essential amino acids, along with healthy fats, B vitamins, and about 20% of your daily iron needs.
Hemp seeds stand out for their remarkable content of quality proteins, including edestin and albumin, and are also rich in healthy lipids with a high content of polyunsaturated fatty acids such as linoleic acid (omega-6), alpha-linolenic acid (omega-3), and vitamins E, D, and A. Hemp seed protein also has a good digestibility rate, ranging from 84 to 86% for whole seeds. That level of digestibility, combined with its complete amino acid profile, makes hemp a genuinely rare find in the plant protein world.
5. Lentils
Lentils are one of those foods that quietly do everything right. As part of the legume family, lentils are a plant-based protein that contains about 9 grams of protein per half-cup cooked serving. They are rich in protein and iron, making them a nutrient-dense option particularly for those following plant-based diets. When you scale that up to 100 grams, the protein count clearly eclipses the egg, and the additional fiber, iron, and folate make them a nutritional overachiever by almost any measure.
Plant proteins like lentils come with fiber, iron, and folate – unlike eggs. While lentils on their own aren’t a complete protein, sprouting them can change that – when sprouted, all 9 essential amino acids become available. Economically, whole-food plant proteins like lentils often cost less than eggs per gram of protein, especially when bought dried or in bulk. For anyone watching both their budget and their macros, lentils are one of the most practical foods on the planet.
6. Cottage Cheese
Cottage cheese has had quite the comeback in recent years, and the data backs up the enthusiasm. It’s a protein powerhouse, offering around 11g per 100g, and it contains casein, a slow-digesting protein that’s ideal for muscle repair and keeping hunger at bay. Cottage cheese has surged in popularity as a go-to high-protein food, with global sales jumping roughly 9% in 2024, and searches for its protein content spiked around 25% last year amid rising interest in protein-rich diets.
A half-cup serving of around 113 grams delivers 12–15 grams of protein – roughly 25% of the daily recommended intake for an average adult, based on USDA guidelines updated in early 2025. Protein from cottage cheese is complete, containing all essential amino acids, which supports muscle repair and satiety. It is naturally rich in protein and calcium, and has a creamy consistency even though it’s lower in calories and saturated fat than other dairy products. It is, in short, one of the most efficient whole-food protein sources you can keep in your fridge.
