Peas are often overlooked as a mundane vegetable, but they are cheap, widely available, and packed with nutrients that can benefit health. While not a miracle food, regular consumption can contribute significantly to daily protein, fibre, and micronutrient intake.
Cooked green peas provide around 5g of protein per 100g, more than most vegetables, and contain all nine essential amino acids. Although they are relatively low in sulphur-containing amino acids, this is not an issue when eaten alongside other protein sources. Pea protein also has good bioavailability, meaning the body can absorb it effectively.
Peas are an excellent source of dietary fibre, with 100g of cooked peas providing over 6g. They contain both insoluble and soluble fibre, aiding digestion and helping regulate blood sugar and cholesterol. Additionally, prebiotic fibres in peas support a healthy gut microbiome.
Iron content in peas is higher than in many common vegetables, though mature peas contain phytic acid which can limit absorption. Green peas, such as garden peas and petit pois, have a better iron-to-phytate ratio, enhancing iron bioavailability. Peas also contain flavonoids, which have antioxidant and anti-inflammatory properties linked to reduced risk of chronic diseases.
Cost is a major factor, and peas are one of the cheapest ways to add protein and fibre to meals. Frozen peas cost around £1 to £1.50 per kilogram, often cheaper than other vegetables, and generate little waste as you can cook only what you need.
