Green Peas (Matar)
The highest-protein common vegetable. Fresh from November to March; frozen peas are scientifically proven to retain nutrition better than off-season fresh.
TLDR — What You Need to Know
- Green peas have 5.4g protein per 100g — the highest protein content among vegetables commonly eaten in India, comparable to several legumes
- Fresh peas are seasonal (November to March in North India) — outside this window, frozen peas are nutritionally superior to off-season fresh peas stored in cold chain
- Complete amino acid profile including leucine — the amino acid that triggers muscle protein synthesis, making peas a valuable plant protein for vegetarians
- Low GI vegetable despite natural sweetness — the fibre and starch structure slows glucose absorption effectively
- Vitamin K 24µg per 100g — important for bone health and blood clotting
- High FODMAP — those with IBS should limit portion size to avoid bloating
What Are Green Peas?
Green peas (Pisum sativum) are the immature seeds of the pea plant, harvested before they harden and dry. They belong to the legume family (Fabaceae) and are botanically classified as legumes, though they are used culinarily as vegetables. The pea plant is one of the oldest cultivated crops in human history — archaeological evidence from the Middle East places pea cultivation at over 9,000 years ago.
In India, green peas are called Matar in Hindi and are predominantly a winter crop. The major producing states are Uttar Pradesh, Madhya Pradesh, Punjab, and Himachal Pradesh. The harvest window for fresh peas in North India runs from November to March, after which they are either frozen for year-round supply or replaced by dried split peas (yellow matar) in cooking.
Green peas occupy a nutritional middle ground between vegetables and legumes. They are richer in protein and starch than most vegetables but lighter and more vegetable-like in texture and cooking versatility than dried legumes. This hybrid character makes them uniquely valuable in Indian cuisine, appearing in everything from Matar Paneer to Pea Pulao, samosas to soups.

Health Benefits
1. Plant protein with a strong amino acid profile
At 5.4g of protein per 100g, green peas deliver more than twice the protein of most vegetables. Broccoli has 2.8g, spinach 2.9g, carrot 0.9g — green peas outperform all of them. More importantly, green peas contain a well-rounded amino acid profile that includes leucine, isoleucine, and valine (branched-chain amino acids), lysine, and methionine in modest amounts. Leucine is the key amino acid that signals muscle protein synthesis via the mTOR pathway. Pea protein isolate has become one of the dominant plant protein supplements globally precisely because the amino acid profile supports muscle building in a way most plant proteins do not. Eating whole green peas delivers this protein with the added benefit of fibre, vitamins, and phytochemicals.
2. Fibre — 5.1g per 100g
Green peas contain a combination of soluble and insoluble fibre. The soluble component (pectins and galactans) feeds beneficial gut bacteria and contributes to bile acid sequestration, supporting cholesterol management. The insoluble component adds bulk and improves bowel transit. At 5.1g fibre per 100g, a 150g serving of green peas provides roughly 30% of the daily fibre requirement for an adult.
3. Vitamin K and bone health
Vitamin K activates osteocalcin, the protein matrix that binds calcium into bone tissue. Without adequate Vitamin K, bones absorb calcium poorly regardless of dietary calcium intake. Green peas provide 24µg Vitamin K per 100g — contributing meaningfully to the 90–120µg daily requirement. For vegetarians and vegans who rely on plant sources for bone nutrients, green peas are an important Vitamin K source alongside leafy greens.
4. Folate — pregnancy and cell division
At 65µg folate per 100g, green peas are an excellent plant source of folate. Folate is essential for DNA synthesis, red blood cell formation, and preventing neural tube defects in early pregnancy. Women of childbearing age benefit significantly from including folate-rich foods like green peas in their diet.
5. Antioxidant compounds
Green peas contain carotenoids (lutein and zeaxanthin), Vitamin C (40mg/100g), and polyphenols including catechins and epicatechin. Lutein and zeaxanthin accumulate in the macular region of the retina and are associated with reduced risk of age-related macular degeneration. The combined antioxidant load of green peas is substantial for their caloric contribution.
6. Low GI despite sweetness
Green peas taste sweet because they contain naturally occurring sucrose (3.3g/100g), but their glycaemic index is approximately 48 — classified as low. The fibre and resistant starch in the seed slow digestion, preventing the blood sugar spike their sweetness might suggest. For comparison, dried yellow split peas have an even lower GI of ~22, and whole cooked peas outperform processed foods despite similar sugar content.
Fresh vs Frozen: The Counterintuitive Truth
The common assumption that fresh is always superior to frozen is incorrect for green peas. Fresh peas begin losing sugars and nutrients immediately after harvest because the plant’s enzymes continue breaking down sugars and Vitamin C after picking. Within 24–48 hours at room temperature, fresh peas can lose up to 50% of their Vitamin C. Within days in cold storage, the sweetness and nutritional value continue to decline.
Frozen peas are blanched (brief high-temperature treatment) and frozen within hours of harvest — arresting enzymatic activity at peak ripeness. Studies comparing frozen peas to fresh peas sold in supermarkets consistently find that frozen peas have equal or higher Vitamin C and equal protein content. The British Food Standards Agency study found frozen peas contained significantly more Vitamin C than fresh peas that had been stored for 2–3 days.
Practical rule: Buy fresh peas only when in season and consumed within 1 day of purchase. For all other times, frozen peas are the nutritionally superior and more economical choice.
Side Effects and Who Should Be Cautious
Purine content and gout: Green peas contain moderate amounts of purines, which break down to uric acid. Patients with gout or hyperuricaemia should limit green pea intake to small portions and monitor uric acid levels. They are considerably lower in purines than red meat or organ meats, but they do contribute.
High FODMAP: Green peas are classified as high FODMAP due to their galactooligosaccharide content. Those with IBS (particularly diarrhoea-predominant or mixed IBS) should limit servings to approximately 40g per meal during symptomatic periods. Canned peas (rinsed) are lower in FODMAPs than fresh or frozen.
Digestive gas: The oligosaccharide fibre ferments in the colon, producing gas. This is universal and not harmful. Cooking thoroughly and combining with digestive spices (cumin, asafoetida/hing) reduces this effect significantly.
Organic vs Conventional
Green peas carry moderate pesticide concern. They are not on the EWG Dirty Dozen but conventionally farmed peas are sprayed with fungicides, insecticides, and herbicides during the growing season. Since the edible seed is inside a pod and is typically cooked, exposure is lower than for thin-skinned produce. Choose organic when available; for frozen peas, organic frozen options are increasingly accessible.
How to Select and Store
Selecting fresh peas: Choose bright green, plump pods that feel full and heavy. Shake the pod — you should hear/feel the peas inside. Avoid yellow or wrinkled pods. When buying shelled peas, they should be bright green, firm, and uniformly sized.
Storing fresh peas: Refrigerate unshelled pods immediately in a perforated bag. Use within 2–3 days for best nutritional retention. If you shell them, use within 24 hours or blanch and freeze.
Freezing fresh peas: Blanch shelled peas in boiling water for 2 minutes, plunge into ice water, drain, and freeze in a single layer before transferring to a bag. Retains nutrition for 6–9 months.
Green Peas vs Edamame vs Corn — Plant Protein Comparison
| Nutrient (per 100g) | Green Peas | Edamame (shelled) | Sweet Corn |
|---|---|---|---|
| Calories | 81 kcal | 121 kcal | 86 kcal |
| Protein | 5.4g | 11.9g | 3.3g |
| Fibre | 5.1g | 5.2g | 2.0g |
| Vitamin C | 40mg | 6mg | 7mg |
| Vitamin K | 24µg | 31µg | 0.3µg |
| Glycaemic Index | ~48 | ~15 | ~60 |
| FODMAP | High | High | Low-medium |
Edamame leads on protein but is less commonly available fresh in India. Green peas win on Vitamin C and have a lower GI than corn. All three are high-protein options by vegetable standards.

Home Test: Artificial Colouring Test for Frozen or Packaged Green Peas
Steps
- 1 Take 10–15 peas from the packet and place in a glass of warm water
- 2 Stir gently and observe the water after 2–3 minutes
- 3 Natural peas release minimal colour — water stays largely clear or very faintly green
- 4 Artificially coloured peas leach significant green colour into the water within minutes
- 5 Remove a pea and rub it between your fingers on a white cloth
- 6 Natural peas leave no significant green stain; artificially coloured peas stain the cloth green
Pure / Pass
Water remains clear or very faintly tinted. No green stain on white cloth. Peas are naturally coloured and safe for consumption.
Adulterated / Fail
Water turns noticeably green within 2–3 minutes. Green stain left on white cloth. Peas have been treated with artificial green colouring (malachite green or similar dyes) — avoid consumption, particularly for children.

Frequently Asked Questions
Q Are frozen peas less nutritious than fresh peas?
Are frozen peas less nutritious than fresh peas?
No — frozen peas are often more nutritious than fresh peas sold off-season. Peas begin losing Vitamin C and sugars within hours of harvest. Frozen peas are blanched and frozen within hours of picking, locking in nutrition. Fresh peas are superior only when bought directly from a farm and consumed the same day.
Q Can green peas be eaten raw?
Can green peas be eaten raw?
Yes, young fresh peas can be eaten raw directly from the pod — they are sweet and crunchy. However, raw peas contain lectins and trypsin inhibitors that can cause digestive discomfort in large amounts. Light cooking deactivates these compounds. Raw consumption of small quantities as a snack or salad addition is fine for most people.
Q Is green pea protein as good as whey protein for muscle building?
Is green pea protein as good as whey protein for muscle building?
Pea protein isolate has been shown in several RCTs to produce comparable muscle hypertrophy to whey protein when consumed in equal doses post-workout. Pea protein is particularly rich in arginine and BCAAs, though it is lower in methionine than whey. For vegetarians and vegans, peas (whole and as isolate) are among the best plant protein sources available.
Q Do green peas cause weight gain due to their calorie content?
Do green peas cause weight gain due to their calorie content?
Green peas at 81 kcal per 100g are not high-calorie foods. Their high protein (5.4g) and fibre (5.1g) content makes them very satiating, reducing overall caloric intake. Studies on high-protein diets consistently find that protein-rich plant foods like legumes and peas support weight management. The concern is more about portion size in high-fat preparations like Matar Paneer, not the peas themselves.
