Foods High in Protein: Best Sources Ranked by Density
· Rebecca Thompson
Anyone who has tried to up their protein intake without supplements knows the challenge: balancing taste, convenience, and grams. The truth is, many everyday foods pack more protein per bite than most shakes, with chicken breast delivering 31 g per 100 g, making it one of the densest sources available.
Chicken breast (cooked, skinless): 31 g per 100 g ·
Egg (large): 6 g per egg ·
Greek yogurt (plain, nonfat): 10 g per 100 g ·
Daily recommended intake (adult): 0.8 g per kg body weight ·
100 g protein target: Achievable with 3–4 servings of high-protein foods
Quick snapshot
- Chicken breast: 31 g per 100 g (Healthline)
- Egg: 6 g per large egg (Healthline)
- RDA for protein: 0.8 g per kg body weight (Healthline)
- Optimal protein intake for athletes (ranges 1.2–2.0 g/kg)
- Whether plant protein builds muscle as effectively as animal protein in all populations
- Current protein data sourced from USDA FoodData Central, updated regularly
- Ongoing research into protein quality (PDCAAS) for plant-based sources
Six everyday foods illustrate the range of protein density, from dense animal sources to middle‑ground plant options.
| Food | Protein per 100 g | Source |
|---|---|---|
| Chicken breast (cooked) | 31 g | Healthline |
| Egg (large) | 6 g per egg | Healthline |
| Greek yogurt (plain) | 10 g | Healthline |
| Tuna (canned in water) | 30 g | Healthline |
| Lentils (cooked) | 9 g | Healthline |
| Almonds | 21 g | Healthline |
What food has the highest protein?
Chicken breast tops the list with 31 g of protein per 100 g, according to Healthline. Turkey breast follows closely, offering 26 g per 3‑ounce serving. Among seafood, shrimp provides 23 g per 100 g and tilapia 26 g per 100 g — both with fewer than 130 calories per serving.
What food is the king of protein?
- Chicken breast (31 g/100 g) — 73% of its calories come from protein.
- Turkey breast (26 g per 3‑ounce serving) — also rich in niacin and selenium.
- Egg whites — almost pure protein with negligible fat.
Ten foods that deliver the most protein per 100 g include:
- Chicken breast – 31 g
- Turkey breast – 30 g
- Tuna – 30 g
- Shrimp – 23 g
- Tilapia – 26 g
- Greek yogurt – 10 g
- Cottage cheese – 11 g
- Lentils – 9 g
- Almonds – 21 g
- Eggs – 6 g each
The pattern is clear: animal proteins dominate the top spots, but several plant options hold their own.
How to get 100 grams of protein a day?
Reaching 100 g is achievable with three meals plus a snack — no shakes needed. According to Gourmend Foods, 100 g of protein equals roughly 14 ounces of cooked chicken breast or 15 large eggs.
Sample meal plan for 100 g protein
- Breakfast: 2 eggs (12 g) + Greek yogurt (10 g) → 22 g
- Lunch: 4 oz chicken breast (31 g) → 31 g
- Snack: 1 oz almonds (6 g) + 1 cup milk (8 g) → 14 g
- Dinner: 5 oz salmon (25 g) + ½ cup lentils (8 g) → 33 g
- Total: 100 g
Most people can hit 100 g by simply including a protein source at each meal. No supplements, no complicated math — just swapping a few ingredients.
Using protein shakes and supplements
Whole foods should be the foundation, but shakes can fill gaps. A typical whey shake provides 20–30 g per scoop — roughly the same as 3–4 ounces of chicken. For anyone short on time, Gourmend Foods notes that 100 g of protein equals about 4.5 chicken breasts, a helpful mental benchmark.
The implication: A shake can replace one meal’s protein but should not substitute for whole food’s vitamins and fiber.
How can I increase my protein?
Small tweaks to existing meals make a big difference. Adding an egg, a spoonful of yogurt, or an extra ounce of meat bumps protein without changing your routine dramatically.
Ways to add protein to meals
- Top oatmeal with milk and nuts
- Add chickpeas to salads and soups
- Mix cottage cheese into scrambled eggs
- Choose Greek yogurt over regular yogurt
Protein-rich snacks
- Nuts and seeds (almonds: 6 g per ounce)
- Cheese sticks (7 g each)
- Hard-boiled eggs (6 g each)
Is 2 eggs a day enough protein?
Two eggs provide about 12 g of protein — less than a quarter of the minimum RDA for a 150‑lb adult. They are a good start but not enough on their own. Pair them with yogurt or a side of meat to reach daily needs.
The trade-off: Eggs are affordable and nutrient‑dense, but relying on them alone leaves a large gap. Combine with other sources.
For most adults, 2 eggs are a supplement, not a solution. Use them as part of a varied high‑protein diet.
The implication: diversifying protein sources ensures adequate intake.
What drink is high in protein?
Cow’s milk contains about 8 g of protein per cup. Soy milk offers a comparable 7–8 g per cup, making it the best plant‑based option. Commercial protein drinks can exceed 20 g per serving.
Milk and soy milk
- Whole milk: 8 g per cup
- Soy milk: 7–8 g per cup
- Almond milk: only 1 g per cup
Protein shakes and smoothies
Homemade smoothies with milk, yogurt, and fruit easily reach 15–25 g. Ready‑to‑drink shakes from brands like Fairlife or Orgain often pack 30 g per bottle.
Drinks with more protein than an egg
- Milk (8 g) > egg (6 g)
- Protein shake (20–30 g) > egg
The pattern: Dairy and soy drinks are the only everyday beverages that meaningfully contribute to protein goals.
What are signs of protein deficiency?
Severe deficiency is rare in developed countries, but mild shortages show up as hair thinning, brittle nails, muscle weakness, and edema (fluid retention). The RDA of 0.8 g per kg body weight covers most sedentary adults; athletes and older adults may need up to 2.0 g per kg.
Symptoms of low protein intake
- Hair loss and thinning
- Muscle wasting
- Swollen feet or ankles (edema)
- Frequent infections (immune function depends on protein)
Who is at risk?
- Vegetarians and vegans who do not plan meals carefully
- Older adults with reduced appetite
- Athletes in heavy training without increased intake
How much protein do you need?
Multiply your weight in kg by 0.8 g for baseline needs. For a 70 kg (154 lb) adult, that is 56 g per day. Active individuals often aim for 1.2–2.0 g per kg.
Why this matters: Hitting even the low end prevents deficiency symptoms; going higher supports recovery and muscle preservation.
Six protein sources, one pattern: animal foods deliver more protein per calorie than most plants, but legumes and nuts offer valuable fiber alongside their protein.
| Food | Protein per 100 g | Calories per 100 g | Protein % of calories |
|---|---|---|---|
| Chicken breast | 31 g | 165 | 73% |
| Turkey breast | 30 g | 135 | 85% |
| Tuna (canned) | 30 g | 130 | 92% |
| Greek yogurt (nonfat) | 10 g | 59 | 68% |
| Lentils (cooked) | 9 g | 116 | 31% |
| Almonds | 21 g | 579 | 15% |
Not all proteins are equal in amino acid composition. The table below shows completeness (presence of all nine essential amino acids).
| Food | Complete protein? | PDCAAS (approx.) | Notes |
|---|---|---|---|
| Chicken breast | Yes | 1.0 | All essential amino acids |
| Egg | Yes | 1.0 | Gold standard reference |
| Greek yogurt | Yes | 1.0 | Rich in casein |
| Lentils | No | 0.52–0.76 | Low in methionine; pair with grains |
| Almonds | No | 0.23–0.40 | Low in lysine |
| Tofu | Yes | 0.95 | Complete, comparable to animal |

Frequently Asked Questions
Can you eat too much protein?
Yes, intakes above 2.5 g per kg body weight for extended periods may stress kidneys and lead to dehydration. Stick to recommended ranges.
Is plant protein as good as animal protein?
For muscle building, animal protein is more efficient per gram, but a varied plant diet can meet needs. Complementary proteins (e.g., rice and beans) fill amino acid gaps.
How much protein do I need after a workout?
20–40 g of high‑quality protein within two hours post‑exercise supports muscle repair. A shake or a chicken breast works equally well.
What are the best high-protein foods for weight loss?
Chicken breast, fish, eggs, Greek yogurt, and legumes — they keep you full with fewer calories. Avoid processed meats high in saturated fat.
Do eggs have all the essential amino acids?
Yes, eggs are a complete protein and serve as the reference standard for protein quality. One large egg provides about 6 g of protein.
Are protein powders safe?
Most whey and plant powders are safe when used as directed. Some may contain heavy metals or artificial sweeteners; choose third‑party tested brands.
What is the difference between complete and incomplete proteins?
Complete proteins contain all nine essential amino acids; incomplete proteins are missing at least one. Animal foods are complete; plant foods are usually incomplete, but combinations (e.g., beans + rice) work.
The implication: understanding these nuances helps tailor protein intake to individual needs.
For anyone building muscle or simply trying to eat better without supplements, the choice is clear: prioritize chicken, eggs, and yogurt over processed bars, because whole foods deliver a better nutrient package per gram. For vegetarians, the path is to combine legumes, grains, and tofu to match animal‑source completeness. You can hit your protein goal with real food — no powders required.
