Peas Health Benefits & Nutrition

Highest Protein of Any Common Vegetable

Green peas contain 5.42g of protein per 100g — 27% of their total calories. A cup of peas provides 7.9g of protein — more than an egg. While pea protein is not complete (low in methionine), it is significantly higher than any other common vegetable. Pea protein is now widely used in plant-based protein supplements due to its amino acid profile and digestibility. Regular green peas are also rich in lysine — an essential amino acid often limited in plant foods.

Exceptional Fiber Content

Peas provide 5.1g of fiber per 100g — the highest of any common vegetable. A cup of peas covers 18% of the daily fiber requirement. The fiber is a mix of soluble (which lowers cholesterol and feeds gut bacteria) and insoluble (which promotes bowel regularity). Pea fiber is particularly rich in pectin, which has been shown to reduce LDL cholesterol and improve blood sugar control.

Blood Sugar Management

Despite containing 14.5g of carbs per 100g, peas have a moderate glycemic index of ~48 — significantly lower than their carb content suggests. This is due to the combination of fiber, resistant starch, and protein slowing glucose absorption. Studies show that replacing other carbohydrate sources with peas improves glycemic control in diabetics. The protein content triggers insulin-independent glucose uptake mechanisms.

Cardiovascular Benefits

Peas contain multiple cardiovascular-protective compounds: fiber (lowers LDL), folate (reduces homocysteine), vitamin K (prevents arterial calcification), and antioxidants including catechin and epicatechin. A 2019 review found that legume consumption (including green peas) was associated with 14% lower cardiovascular disease risk and 10% lower risk of coronary heart disease.

Frequently Asked Questions

How many calories in peas?
Peas contain 81 calories per 100g. A cup of green peas (145g) has 117 calories. A quarter cup has 41 calories. Use the slider above for any weight.
Are peas a vegetable or legume?
Botanically, peas are legumes (seeds of the Pisum sativum plant). Culinarily and nutritionally, green peas are classified as vegetables. Dried peas (split peas) are classified as legumes. The distinction matters little nutritionally — both are healthy foods.
Are peas high in protein?
Yes — peas have the highest protein content of any common vegetable at 5.42g per 100g. A cup provides 7.9g of protein. While not a complete protein, peas are rich in lysine and combine well with grains to form complete proteins.
Are peas keto?
No. Peas have 9.4g of net carbs per 100g. A cup has 13.1g of net carbs — too many for ketogenic diets. Even small portions can use up a significant portion of the daily keto carb limit.
Are frozen peas as nutritious as fresh?
Yes — frozen peas are typically as nutritious or more nutritious than fresh peas. They are flash-frozen within hours of harvest, preserving vitamins. Fresh peas lose up to 50% of their vitamin C within 24-48 hours of harvest. Unless buying truly fresh local peas, frozen are often the better nutritional choice.
Can you eat peas raw?
Yes — raw peas are sweet and crisp. They retain maximum vitamin C and other heat-sensitive nutrients. Snow peas and sugar snap peas are particularly good raw. Standard garden peas (shelling peas) are also excellent raw, though tougher-skinned varieties may be more digestible cooked.
