What Does 1 Cup of Peas Mean?
When a recipe calls for "1 cup of peas," the meaning can differ slightly depending on the form of the peas. The volume measurement remains the same, but the weight and nutritional content vary significantly between fresh, frozen, canned, and dried peas. For most standard cooking, a 1-cup reference typically applies to shelled green peas, either fresh or frozen.
For shelled green peas, one cup is generally around 145 to 160 grams. Frozen green peas are similarly weighted, with one cup being approximately 134 to 160 grams, depending on the source. The weight can be affected by the amount of water or ice crystals present. Canned peas, which include liquids, will have a different weight-to-volume ratio, as well as a different nutrient profile, particularly concerning sodium levels. Dried split peas, once rehydrated and cooked, expand considerably, with 1 cup dry yielding 2 to 2.5 cups cooked.
It is important to pay attention to the specific type of pea for precise measurements and nutritional information. For example, a cup of sugar snap peas weighs less than a cup of green peas because of the pod, which is eaten whole.
The Nutritional Power of 1 Cup of Peas
Despite their small size, peas are a fantastic source of plant-based protein, fiber, and an array of essential vitamins and minerals. The specific nutritional values can vary based on preparation and type, but they are consistently a healthy addition to any meal.
Key Nutrients in 1 Cup of Cooked Green Peas
A single cup (160g) of cooked green peas, without added salt, is packed with beneficial compounds:
- Protein: 8.6 grams, an excellent plant-based source.
- Dietary Fiber: 8.8 grams, which is over 30% of the Daily Value, crucial for digestive health.
- Vitamins: A good source of Vitamins K (41.4 mcg), C (22.7 mg), and folate (101 mcg).
- Minerals: Rich in manganese (0.84 mg), potassium (433.6 mg), magnesium (62.4 mg), and iron (2.46 mg).
- Antioxidants: High levels of lutein and zeaxanthin support eye health.
Comparison: Fresh vs. Frozen vs. Canned Peas
The processing and preparation of peas significantly impact their nutritional content. Frozen peas are often flash-frozen at their peak ripeness, preserving most of their nutrients, while fresh peas may lose some vitamins over time after picking. Canned peas can lose more nutrients during processing and often have higher sodium content due to added salt.

Potential Downsides and Considerations
While generally beneficial, peas do have some considerations. They contain compounds called antinutrients, such as phytic acid, which can interfere with the absorption of some minerals, though this is typically only an issue with very high consumption. Soaking and cooking can reduce the levels of these compounds. Additionally, the high fiber content can cause bloating or gas for some individuals, particularly in large quantities.
