Green Peas Nutrient Profile: Protein, Fiber, And More
Green peas, or garden peas (Pisum sativum), provide a nutrient-dense profile per one cup (160g) cooked, boiled, and drained without salt: 134 calories, 8.6g protein, 25g carbohydrates (including 8.8g dietary fiber and 9.5g sugars), 0.4g fat, plus key vitamins and minerals like 23mg vitamin C (25% DV), 41mcg vitamin K (34% DV), 102mcg folate (26% DV), 433mg potassium (9% DV), and 2.5mg iron (14% DV).

Nutritional Breakdown
One cup of cooked green peas delivers 8.6 grams of plant-based protein, making them a standout legume for vegetarians and vegans seeking complete amino acid profiles. This serving also packs 8.8 grams of fiber-mostly insoluble for digestive health-while keeping calories low at 134, with minimal fat (0.4g total, mostly polyunsaturated). [][]
Historically, green peas have been cultivated since 7000 BCE in the Near East, valued for their protein content; a 2016 study in Today's Dietitian noted they contain 25.5% protein by dry weight, far exceeding many vegetables. Registered dietitian Michela Palma, RD, LD, stated in a 2025 Cleveland Clinic report, "Green peas are an excellent source of protein, fiber and nutrients," highlighting their role in heart and eye health.

Macronutrients Deep Dive
Protein in green peas stands at 5.4-8.6g per 100-160g serving, offering all essential amino acids unlike many plant sources; this equates to 26% of caloric content from protein in cooked peas. Fiber totals nearly 9g per cup, with 5.5g insoluble promoting bowel regularity-vital since average U.S. intake is just 13g daily, per 2016 fiber research. [][]
- Protein: 8g per cup supports muscle repair; peas outpace green beans 4:1 in protein density. []
- Fiber: 8-9g per cup (31% DV), blending soluble (2g) and insoluble (5.5-6g) for cholesterol reduction and satiety. [][]
- Carbs: 23-25g, mostly complex with natural sugars for steady energy; net carbs ~14-15g after fiber. [][]
- Fats: Trace 0.4g, heart-healthy polyunsaturated dominant. []
Micronutrients and Antioxidants
Green peas shine in vitamins: 23mg vitamin C (48% DV raw equivalent) boosts immunity, while 41mcg vitamin K aids clotting and bone health. Folate at 102mcg (26% DV) is crucial for DNA synthesis, especially vital post-2020 pregnancy nutrition guidelines emphasizing 600mcg daily. [][]
- Vitamin A (1282 IU, 19% DV via beta-carotene): Protects eyesight; lutein/zeaxanthin (4149mcg) combats age-related macular degeneration. []
- B-Vitamins: Thiamin (0.41mg, 34% DV), niacin (3.2mg, 20% DV), B6 (0.35mg) for metabolism; originated in sub-Himalayan cultivation ~7000 BCE. [][]
- Minerals: Iron (2.5mg, 14% DV) with vitamin C for absorption; manganese (0.84mg, 37% DV), zinc (1.9mg, 17% DV), phosphorus (187mg, 15% DV). []
- Antioxidants: Polyphenols and phyto-nutrients reduce inflammation, per 2024 Silva International analysis. []
"Peas offer over four times the protein content of green beans and more than three times the fiber," notes a 2025 Health.com comparison, underscoring their superior nutrient density. []
Health Benefits
High fiber content in green peas (8.8g/cup) supports gut health by adding stool bulk, reducing constipation risk by 30% in high-fiber diets per 2023 meta-analyses. Protein and low glycemic index (GI ~48) stabilize blood sugar, beneficial for diabetes management. [][]
Cardiovascular perks include potassium (434mg) countering sodium, plus insoluble fiber lowering LDL cholesterol; a 2025 Cleveland Clinic review linked pea consumption to improved heart metrics. Eye health from lutein combats oxidative stress, with peas providing 4148mcg per cup. [][]
Comparison to Other Vegetables
Versus green beans, green peas deliver 7.9g vs. 1.8g protein and 8.3g vs. 2.7g fiber per cup, per 2025 data-ideal for low-carb diets. Dry peas amp fiber to 16g/cup but suit different recipes. Against spinach, peas edge in protein (8g vs. 6g) but trail in vitamin K. [][]

Culinary and Storage Tips
- Boil fresh peas 2-3 minutes to retain 90% nutrients; freezing preserves 95% vs. canning's 60% loss, USDA 2024 data. []
- Portion: 1/2-1 cup daily maximizes benefits without excess sugars (9g/cup). []
- Pair with rice for complete protein; add to soups for fiber boost. []
Historical Context
Originating in northwest India's sub-Himalayan plains around 7000 BCE, green peas spread via Silk Road trade by 500 CE, becoming staples in European diets post-16th century. Gregor Mendel's 1860s pea pod experiments laid genetics foundations, underscoring their scientific legacy. Today, global production hits 12 million tons annually (FAO 2025). []
Sourcing and Sustainability
Opt for organic peas to minimize pesticides; U.S. yields peaked at 1.5 million tons in 2024. Frozen varieties from sustainable farms retain full nutrient profile, reducing waste by 30% vs. fresh imports. []

Everything you need to know about Green Peas Nutrient Profile Protein Fiber And More
Are raw green peas safe to eat?
Raw green peas are safe and retain higher vitamin C (up to 48% DV), but cooking improves digestibility and kills potential lectins; limit raw to 1/2 cup to avoid bloating. []
Do green peas cause gas?
Yes, raffinose sugars ferment in the gut, but soaking or cooking reduces this by 50%; introduce gradually to build tolerance. []
Are green peas keto-friendly?
Moderately: 14g net carbs/cup fits low-carb but not strict keto (<20g daily); opt for smaller 1/4-cup servings. []
What's the protein in frozen vs. fresh peas?
Frozen peas match fresh at ~8g/cup cooked, with identical macros if boiled unsalted; freezing post-harvest locks in nutrients. [][]
Can green peas help with weight loss?
Absolutely: 134 calories/cup with 8.8g fiber promotes fullness; 2025 studies show legume intake aids 5-10% body weight reduction over 12 weeks. [][]
