When it comes to building and repairing muscles, protein is an essential nutrient that plays a vital role in our overall health and well-being. However, with the rising costs of food and supplements, finding affordable sources of protein can be a challenge. In this article, we will delve into the world of protein-rich foods and supplements to uncover the cheapest source of protein per gram.
Understanding Protein and Its Importance
Protein is a macronutrient composed of amino acids, which are the building blocks of our bodies. It is responsible for repairing and building tissues, including muscles, bones, skin, and hair. Protein also plays a crucial role in producing enzymes, hormones, and other biomolecules that regulate various bodily functions.
The recommended daily intake of protein varies based on factors such as age, sex, weight, and activity level. Generally, the recommended daily intake of protein is:
- 0.8 grams per kilogram of body weight for sedentary adults
- 1.2-1.6 grams per kilogram of body weight for active adults
- 1.6-2.2 grams per kilogram of body weight for athletes or those who are trying to build muscle
Types of Protein Sources
There are two main types of protein sources: animal-based and plant-based.
Animal-based protein sources include:
- Meat (beef, pork, lamb, etc.)
- Poultry (chicken, turkey, duck, etc.)

What is the most affordable source of protein per gram?
The most affordable source of protein per gram is often debated, but some of the top contenders include beans, lentils, and eggs. These foods are not only rich in protein but also relatively inexpensive compared to other protein sources like meat and fish. Additionally, they are often rich in other essential nutrients like fiber, vitamins, and minerals.
When considering the cost of protein per gram, it’s essential to look at the overall nutritional value of the food rather than just its protein content. For example, while beans and lentils may not have as much protein per serving as eggs, they are often lower in calories and higher in fiber, making them a more nutritious choice.
How do I calculate the cost of protein per gram?
To calculate the cost of protein per gram, you need to know the price of the food item and its protein content per serving. You can find this information on the nutrition label or by researching the food item online. Once you have this information, you can calculate the cost of protein per gram by dividing the price of the food item by its protein content.
For example, if a bag of beans costs $1.50 and contains 20 grams of protein, the cost of protein per gram would be $1.50 ÷ 20 grams = $0.075 per gram. This calculation can help you compare the cost of different protein sources and make informed decisions about your diet.
