Defining a Standard Serving
For black-eyed beans, which are botanically a type of cowpea, the standard serving size can vary slightly depending on how they are prepared, but a half-cup of cooked beans is the most common metric used by nutrition authorities like the USDA. This measure applies whether you are using dry beans that have been soaked and cooked, or consuming canned black-eyed peas.
When buying dry black-eyed beans, it is useful to know that one cup of dry beans yields roughly three cups of cooked beans. This means that a standard 16-ounce (one-pound) bag, which holds about two cups of dry peas, can provide up to 12 half-cup servings once cooked. Being mindful of these proportions can help with meal planning and portion control, ensuring you get the nutritional benefits without over-consuming.
Cooked vs. Canned: Serving Size Variations
The serving size for black-eyed beans is consistent across different preparations, but the nutritional content can vary slightly, primarily in sodium levels.
- Cooked from dry: When you cook black-eyed beans from their dried form, you have complete control over the added ingredients, including salt. This allows you to create a low-sodium meal that is purely a half-cup serving of nutrient-rich beans.
- Canned: Canned black-eyed peas are pre-cooked for convenience, but they often contain added sodium for preservation and flavor. While a half-cup is still the standard serving, it's wise to choose low-sodium canned options or rinse the beans thoroughly before use to reduce the sodium content. The convenience of canned beans makes them a quick and easy option for many dishes.

Black-Eyed Peas vs. Other Legumes: A Comparison
While all legumes are nutritious, understanding their differences can help you make informed choices for a balanced diet. Here is a comparison of common legumes based on a half-cup cooked serving.
| Nutrient | Black-Eyed Beans | Chickpeas (approx.) | Red Lentils (approx.) |
|---|---|---|---|
| Calories | ~99 kcal | ~134 kcal | ~115 kcal |
| Protein | ~7 g | ~7.3 g | ~9 g |
| Fiber | ~6 g | ~6.2 g | ~7.8 g |
| Folate (per 1 cup) | ~89% DV | ~71% DV | ~90% DV |
| Iron (per 1 cup) | ~24% DV | ~26% DV | ~37% DV |
All three are excellent sources of nutrients, but red lentils offer a slightly higher protein and fiber content per serving, while black-eyed beans are particularly rich in folate per cup. Chickpeas are a robust source of protein and fiber, making them a well-rounded legume choice.
