There's no single "king," but whey protein isolate (a supplement) and spirulina (a blue-green algae) are highest per gram, followed by dense animal sources like lean meats, fish, eggs, and dairy (cheese, Greek yogurt), plus plant-based powerhouses like soybeans, lentils, and peanuts, all providing excellent complete protein.
To get 100g of protein daily, focus on prioritizing protein at every meal (aiming for 30g+ per meal) by incorporating lean meats, fish, eggs, Greek yogurt, tofu, lentils, and beans, and use protein-rich snacks like nuts, seeds, or protein powder to fill gaps, planning ahead with batch cooking for easy access.
Generally: Animal products (such as chicken, beef or fish and dairy products) have large amounts of all of the essential amino acids and are known as high-quality protein.
There are several foods that are considered to be "kings of protein" due to their high protein content and amino acid profiles. Here are some examples: Eggs: Eggs are a nutrient-dense food that are high in protein, vitamins, and minerals. One large egg contains around 6 grams of protein.
Two eggs a day provide about 12-14 grams of high-quality protein, which is a great start but usually not enough for most adults' daily needs, typically 46-56+ grams, especially for active individuals; you'll need to add protein from other sources like whole grains, beans, Greek yogurt, or lean meats to reach your goals. Eggs are a complete protein, offering all essential amino acids, making them a very nutritious addition to meals, but combining them with other foods helps meet diverse nutrient needs.
Proteins that come from animal sources, such as meat, eggs, and milk, as well as soy and quinoa, are called complete proteins. This means they contain all the essential amino acids the body needs and are the highest-quality protein sources.
Guava. Guava is one of the most protein-rich fruits around. You'll get a whopping 4.2 grams of the stuff in every cup. This tropical fruit is also high in vitamin C and fiber.
A peanut butter and jelly sandwich (PB&J) adds about 33 minutes to your healthy lifespan per serving, according to a University of Michigan study that measured life expectancy impacts of over 5,850 foods using the Health Nutritional Index (HNI). This sandwich tops the list for adding time, with nuts and seeds also being highly beneficial (around 25 mins) and processed items like hot dogs subtracting time.
The "top 3" proteins depend on your goal, but generally include Whey Protein (fast-digesting for muscle recovery), Casein (slow-digesting for sustained release), and high-quality whole foods like Lean Meats/Fish, Eggs, or plant-based options like Soy/Legumes/Quinoa for complete amino acids, with experts often recommending a mix of sources for balanced nutrition.
7 Protein-Packed Foods to Add to Your Diet
When is the best time to consume protein? It's better to spread out your protein consumption evenly throughout the day. On average, people get most of their protein from evening meals and the least from breakfast.
Signs of a protein deficiency
Feeling weak or hungry, since protein supplies energy and satisfies the appetite. Getting sick often without protein to boost the immune system. Mood changes or trouble thinking due to fluctuating blood sugar and protein's effect on the brain's neurotransmitters (which regulate mood)
The vegetable with the most protein is edamame (soybeans), offering around 18-19 grams per cooked cup, followed closely by other legumes like lentils and chickpeas, while even non-legumes like peas, spinach, and Brussels sprouts provide significant protein for plant-based diets, making legumes the top protein source among vegetables.
Protein is essential for muscle repair, immunity, and overall health, and daily needs vary by individual. Drinks like cow's milk, soy milk, kefir, bone broth, and smoothies can provide more protein than an egg.
Beans, tofu, and tempeh have more protein than eggs and some meats, and they also provide dietary fiber, which feeds our good gut bacteria, promotes healthy digestion, and can help lower cholesterol.

The fruit is fairly low in protein, under 1.3 grams per medium banana. The protein content in a banana helps you make informed food choices, ensuring your daily protein requirements are fully met. A single banana contains 1–1.5 grams of protein.
Fruit isn't a high-protein food, but some fruit has protein, including passion fruit, guava, and avocado. These fruits provide approximately 2 g to 5 g of protein per cup. You shouldn't rely on fruit as a main source of protein, because the amounts are too small.
