Best Foods to Eat for Protein | Healthy Protein Sources for Every Diet

Protein is a crucial macronutrient for enhancing body composition. Studies recommend about 0.75 grams per pound of body weight for optimal muscle gain, which can be challenging to achieve for some people (Morton et al., 2018). Fortunately, there are many healthy and accessible protein-rich foods. Adding variety to your protein consumption can be beneficial for increasing novelty and preventing dietary burnout.

High-Protein Animal-Based Foods

Animal-based sources, such as meat and fish, are reliable providers of protein, as well as essential vitamins and minerals. For example, a pound of chicken breast contains about 100 grams of protein and only 500 calories. Leaner protein options are generally more friendly for a calorie deficit, but fattier options can still be beneficial when eaten in moderation.

Fatty fish, such as salmon, are rich in healthy fats and offer excellent overall nutrition. Numerically, a pound of farmed salmon contains 850 calories and roughly the same protein as a pound of chicken breast. Understanding optimal nutrition for muscle building helps you select protein sources that align with your calorie and macronutrient goals.

Best Vegetarian Protein Sources

Vegetarian sources also provide an excellent source of protein. Eggs and dairy products, such as milk, are common options. A single egg contains around 6 grams of protein and 70 calories, while an egg white has about 5 grams of protein and only 20 calories. A glass of skim milk contains about 80 calories and 8 grams of protein.

Among dairy products, plain non-fat Greek yogurt stands out as a high-quality, low-calorie protein source—a 90-calorie serving contains around 17 grams of protein, depending on the brand. While plain yogurt may seem bland, it can be combined with fruit and nuts for a delicious, high-protein snack. These options work well for those following a balanced nutrition approach while meeting protein requirements.

High-Protein Vegan Food Options

Vegan options include tofu, which is low in calories and high in protein—extra firm tofu provides around 8 grams of protein per 70-calorie serving. Lentils are another excellent plant-based source, with about 18 grams of protein per 230-calorie serving, depending on the type.

Grains such as brown rice and quinoa contribute some protein, though in smaller amounts relative to their calorie content (for example, 200 calories of brown rice yields about 5 grams of protein). Nuts also supply protein, but like grains, their protein content is modest; a 160-calorie serving of almonds contains approximately 6 grams of protein. For those pursuing optimal body composition on a plant-based diet, combining multiple vegan protein sources throughout the day ensures adequate intake while meeting all essential amino acid needs.
