Protein is a crucial nutrient. There are numerous benefits to adding protein-rich foods to your diet, including weight loss and increased muscle mass (1, 2).

Luckily, there are many delicious choices that suit every dietary need.

However, some people may find healthy protein sources to be too costly. While some sources of protein are expensive, there are also many affordable alternatives.

Here are 17 healthy protein sources that won’t break the bank.

1. Natural Peanut Butter

Peanut butter is full of protein. It is also cost-friendly, with an average cost of around $2.50 per 16-ounce (454-gram) jar.

A two-tablespoon serving of this creamy nut butter provides 8 grams of protein (3).

Aside from being a great source of protein, peanut butter can be used in many ways. Pair it with fruit and oatmeal or add it to your favorite smoothie for a protein boost.

What’s more, studies have shown that people who include peanuts and peanut butter in their diets are less likely to develop certain chronic diseases like heart disease and diabetes (4, 5).

Choose natural peanut butter when possible to avoid unwanted ingredients like added sugar and oils.

2. Eggs

Eggs are one of the most nutrient-dense foods on the planet, and are very affordable with an average price of $2 to $4 per dozen.

Not only are they full of vitamins, minerals and healthy fats, but they are also packed with protein. One large egg contains 6 grams (6).

Adding eggs to your diet is a great way to increase your protein intake and may also help you reduce your calorie intake and lose weight.

Several studies have shown that having eggs for breakfast helps keep hunger in check by causing you to eat fewer calories throughout the day. This can, in turn, help you lose weight.

For example, one small study found that participants who consumed an egg breakfast for eight weeks lost 65% more weight than those who ate a bagel breakfast (7).

Another study showed that eating eggs for breakfast suppressed the hunger hormone ghrelin and helped stabilize blood sugar and insulin response (8).

Eating eggs may lead to decreased feelings of hunger and fewer cravings, which is great for weight loss.
