Black beans, especially when purchased dried and cooked at home, are generally considered one of the cheapest sources of protein.
While the absolute "cheapest" can fluctuate based on location, sales, and bulk purchasing, black beans offer a significant amount of protein per dollar. Other affordable protein sources include:
- Beans and Lentils: Dried beans (kidney, pinto, etc.) and lentils are consistently budget-friendly. They require cooking, but the cost savings are substantial.
- Eggs: Often sold at competitive prices, eggs are a complete protein source.
- Canned Tuna (in water): A convenient and relatively inexpensive option, especially when on sale.
- Chicken (Drumsticks/Thighs): Typically cheaper than chicken breasts, drumsticks and thighs provide a good protein source.
- Peanut Butter: A plant-based protein source that is widely available and affordable.
To illustrate the cost-effectiveness, consider this comparison:
| Protein Source | Approximate Cost per Serving (Estimates vary by location) | Notes |
|---|---|---|
| Black Beans (dried) | \$0.10 - \$0.20 | Requires cooking from dried state. |
| Lentils (dried) | \$0.15 - \$0.25 | Requires cooking from dried state. |
| Eggs | \$0.20 - \$0.40 | Price depends on grade and quantity. |
| Canned Tuna (in water) | \$0.75 - \$1.25 | Convenient, but watch sodium content. |
| Chicken Drumsticks | \$0.50 - \$1.00 | Price depends on sales and location. |
| Peanut Butter | \$0.30 - \$0.60 | Look for brands with minimal added sugar. |
It's important to compare unit prices (price per ounce or gram of protein) when shopping to determine the absolute cheapest option available at your local stores. Also, consider buying in bulk when possible for further savings.
In summary, while prices fluctuate, black beans remain one of the most cost-effective ways to obtain protein, followed closely by other dried beans and lentils.
