Green peas · cooked

For 100 g of cooked green peas you get roughly 80 kcal, 5 g of protein, 11 g of carbohydrates, 0.4 g of fat and 5.5 g of fibre. It is a very light food in energy terms, yet surprisingly protein-dense for a vegetable: gram for gram, it provides about twice as much protein as carrots or zucchini. Nearly a quarter of the calories come from protein, which is rare in the vegetable aisle.

The carbohydrates are mostly complex, together with a little natural sugar that gives peas their sweet note. The fat content is almost nil, so they do not weigh down your calorie budget. A 150 g portion, about one generous ladle, brings roughly 120 kcal, 7.5 g of protein and more than 8 g of fibre, close to a third of what an adult should aim for each day. It is a far more filling choice than a portion of pasta at equal calories.

Green peas belong to the legume family, and their protein is of good quality for a plant source, but it remains low in sulphur-containing amino acids such as methionine. On the other hand it is rich in lysine, the amino acid that cereals often lack. This is why pairing peas with rice, semolina or pasta is so useful: the two profiles complete each other and you end up with a well-balanced amino acid intake over the day.

Do not count on green peas as your only protein source: at 5 g per 100 g, you would need more than 500 g to reach 25 g of protein. They act instead as a complement: they raise the protein density of a meal, especially when you eat little meat or fish. For a vegetarian lifter, they add usefully to tofu, eggs, dairy and other legumes in order to cover needs of roughly 1.6 to 2 g of protein per kilo of body weight.

With 5.5 g of fibre per 100 g, green peas are among the richest vegetables in fibre. It slows gastric emptying, smooths the rise in blood sugar after the meal and prolongs the feeling of fullness. Part of the fibre is insoluble and supports transit; another part is soluble and feeds the gut microbiota, which contributes to better long-term digestive health and better nutrient absorption.

Be careful, though, if you are not used to them: green peas contain fermentable oligosaccharides that can cause bloating in sensitive people or those with irritable bowel syndrome. Introduce them gradually, chew well, drink enough water and start with portions of 80 to 100 g. Extra-fine frozen peas, which are more tender, are often better tolerated than large canned peas. Also avoid eating a large amount right before an intense workout.

Green peas are a good source of vitamin K, vitamin C, folate (vitamin B9), vitamin B1 and manganese. They also supply iron, phosphorus, magnesium and potassium in useful amounts. Vitamin K contributes to bone health and blood clotting, while folate is involved in red blood cell formation and cell division, a helpful point when you train hard and your body is recovering constantly.

They also contain carotenoids such as lutein and zeaxanthin, as well as polyphenols, which protect cells from the oxidative stress generated by exercise. Plant iron is absorbed less well than iron from meat, but pairing green peas with a source of vitamin C, such as raw bell pepper, a squeeze of lemon or a tomato, clearly improves its absorption. It is a good habit if you limit your intake of animal products.

When bulking, green peas are not your main food, because their calorie density is low, but they earn their place by balancing meals rich in starch and meat. They bring micronutrients, fibre and a bit of protein without blowing up the volume of the plate. Add 150 to 200 g to a dish of rice and chicken, with a little olive oil, to gain variety and nutritional quality.

When cutting, they are even more valuable: for only 80 kcal per 100 g, they fill the plate, curb hunger and keep protein intake decent in a calorie deficit. Replace part of your starches with green peas to cut calories without shrinking the size of the meal. Just watch out for canned versions in salted water, which are higher in sodium, and for creamy or buttery recipes that quickly double the calorie load.

Fresh green peas cook in 5 to 10 minutes in salted boiling water or steamed; frozen ones, already blanched, need only 3 to 5 minutes. Plunge them into cold water after cooking if you want to keep their bright green colour. Overcooking makes them mealy, dulls the colour and destroys part of the vitamin C. You can also pan-fry them with a little garlic and mint, or blend them into a purée or soup.

When buying, frozen peas are often excellent: they are frozen within hours of harvest and keep their vitamins well, sometimes better than fresh peas left for several days in the fridge. For canned peas, choose versions without added sugar and rinse them to cut the salt. Keep shelled fresh peas two to three days in the fridge, cooked peas three days in an airtight container, and never refreeze a product that has thawed.

The first mistake is drowning green peas in butter, cream or a rich sauce: the light vegetable then becomes a high-calorie dish, and you lose its point when cutting. Another classic trap is canned peas in very salty liquid, which inflate your sodium intake and encourage water retention. Always rinse them, or switch to frozen, and season with herbs, lemon or spices.

The second mistake is treating them as a real protein source and cutting your other intake as a result. A meal built only around green peas will leave you far from your protein target. Finally, do not cook them too long: gentle cooking keeps texture, colour and vitamins, whereas prolonged boiling gives a grey, bland mush that nobody wants to finish.
