Searches for “do green beans have protein” continue to trend upward in 2026, often alongside queries like “protein in green beans per serving,” “green beans protein content,” and “are green beans a good protein source.” The straightforward answer is yes—green beans do have protein, typically around 1.8–2 grams per 100-gram serving or 2–3 grams per cup (raw or cooked). While not a high-protein food like mature beans or meat, green beans contribute modest plant-based protein alongside fiber, vitamins, and antioxidants that support overall health.
This comprehensive 2026 guide, informed by USDA data and recent studies, explores whether green beans have protein, how much, and their role in modern diets. From fitness tracking to sustainable eating, discover practical insights for meal planning, brand choices, and emerging trends in a market valuing nutrient-dense vegetables.
Protein Content in Green Beans: Exact Numbers and Variations
Green beans (also called snap beans or string beans) are immature pods of the common bean plant, harvested young—which explains their lower protein compared to dried mature beans.
Standard nutrition per USDA 2026-aligned data:
- Raw green beans (per 100g): ~1.8–2g protein, 31 calories
- Cooked green beans (per 100g): ~1.9g protein, 35 calories
- One cup raw (~110g): ~2g protein
- One cup cooked (~125g): ~2.4g protein
Fresh, frozen, and low-sodium canned versions retain similar protein levels, though canning may slightly reduce water-soluble nutrients.
Fresh vs. Frozen vs. Canned: Protein Comparison Table (2026 Data)
| Type | Protein per 100g | Protein per Cup | Calories per Cup | Key Notes |
|---|---|---|---|---|
| Fresh Raw | 1.8–2g | ~2g | 31–35 | Highest nutrient retention; versatile |
| Fresh Cooked | 1.9g | ~2.4g | 35–40 | Boiled/steamed preserves most protein |
| Frozen Cooked | 1.5–1.9g | ~2g | 35–38 | Convenient; minimal loss during freezing |
| Canned (Drained) | 1–1.5g | ~1.8g | 30–40 | Often higher sodium; rinse to reduce |
| Organic Fresh | 1.8–2.2g | ~2.2g | 30–35 | Premium brands like Earthbound Farm emphasize quality |
Fresh and organic options edge out in micronutrients, while frozen maintains comparable protein for year-round availability.
