Green vegetables are loaded with nutrients. Green peas and green beans are no different. They both contain protein, fiber, vitamins, minerals, and phytonutrients, all of which are necessary for human health. Some green veggies, like peas and beans, are seen as interchangeable by many. Some countries even refer to them by the same name. But these green legumes are distinctive. Evidence is shown in close review of their properties, including in their nutritional content.

What Are Green Peas?

The botanical name for green peas is Pisum sativum L. They belong to the family of plants called Fabaceae or Leguminosae, and are one of the 20, 000 species of global edible/ non-edible legumes. Most of us are familiar with green peas, snow peas and snap peas. Green peas are found in the pods or fruits of the plant. Each pod contains two to ten peas. Commonly known as garden peas or sweet peas, they have a sweetish flavor and starchy texture. Shelled peas are used raw, fresh, canned, or frozen. The plant is a fast-growing, climbing annual, that prefers cooler weather.

What Are Green Beans?

The botanical name for green beans is Phaseolus vulgaris. They also belong to the Fabaceae plant family. Green beans are also known as snap beans, and wax beans. The latter are really yellow ‘green’ beans. There are other species of beans, and colors and shapes within species. They grow in bunches either on the vine (the pole variety) or on a bush. The young pods are eaten fresh. Varieties such as black, kidney and pinto are usually dried. Green beans are about one to two feet in length. The plant is an annual like peas but prefers full sun. Other names for green beans include pole beans, string beans, or stringless beans.

Differences in Green Peas and Green Beans Nutritional Content

Compare one cup of cooked green peas with one cup of cooked green beans. You’ll discover they have several nutrients in common. The differences lie mostly in quantity, but certain minerals and phytonutrients have been discovered in one and not the other.

Nutrients Not Shared by Green Peas & Green Beans

Analysis of green peas found minerals iodine and molybdenum, and phytonutrients coumestrol (polyphenol), ferolic acid and caffeic acid (phenolic acids). Analysis of green beans found it to be “silicon-rich.” Excellent quantities of phytonutrients violaxanthin and neoxanthin were also found in the latter legume (see Sources).

Health Benefits Offered by Nutrients in Green Peas and Green Beans

Both green peas and green beans provide lots of health benefits. Their fiber content slows digestion, preventing blood sugar spikes, and that is especially important to patients with type 2 diabetes. It also feeds healthy gut bacteria, which reduces the risk of issues such as irritable bowel syndrome (IBS) and colon cancer. The insoluble fiber creates bulk, making it easier for the body to dispose of waste matter (see Sources).

The B-vitamins, especially B1, B2, B3, B6 and choline, reduce the risk of cardiovascular diseases and diabetes, promote bone, brain and nervous system health, support metabolism and act as antioxidants. B9 or folate bars buildup of the amino acid homocysteine, preventing birth defects and allowing the brain to produce serotonin and other “happy hormones” without interference (see Sources).

Vitamin C acts as an antioxidant, removing harmful free radicals from the cells. This reduces inflammation, risk of heart and other chronic diseases, promotes the immune system and skin health (see Sources).

Vitamin K promotes bone production, decreases prostate cancer risk, Alzheimer’s disease and is involved in blood clotting (see Sources).

Vitamin E promotes cardiovascular health, cognition, reduces the risk of osteoarthritis, wrinkles and cataracts (see Sources).

Vitamin A helps promote health immune system and vision (see Sources).

The mineral manganese is important for metabolism. Calcium, magnesium, potassium and selenium promote a healthy heart and lower the risk of high blood pressure. Selenium along with zinc promote a healthy immune system and are involved in the production of hormones. Selenium is also important in preventing thyroid disease, premature aging, inflammation, and cancer. Selenium and phosphorus prevent cognitive decline. Zinc also plays a role in proper digestion. Phosphorus is also important for healthy bones and teeth, DNA and RNA production, kidney waste removal, and muscle recovery after workout (see Sources).

Copper promotes healthy skin and hair, prevents osteoporosis, arthritis and cancer, and plays a role in iron absorption (see Sources).

Iodine, which scientists have found in green peas but not green beans, prevents thyroid disease, promotes healthy skin, hair, energy level and fetal development (see Sources).

Molybdenum, another mineral found in green peas but not in green beans, is important in nervous system development, energy production, nitrogen synthesis, waste removal and decreases risk of cancer (see Sources).

Silicon, which scientists have found in green beans but not in green peas, strengthens bones, skin connective tissue and prevents thinning hair (see Sources).

Antioxidant phytonutrient beta-carotene along with lutein and zeaxanthin, found in both legumes, reduce risk of inflammation and cancer, promote healthy skin, vision issues, especially age-related, and brain function. Additionally, the coumestrol found exclusively in green peas seems to prevent stomach cancer. And phenolic acids ferolic acid and caffeic acid prevent inflammatory diseases such as arthritis and type 2 diabetes. In green beans, the carotenoid neoxanthin and xanthophyll violaxanthin, which are biosynthesized from zeaxanthin, show evidence of antioxidant ability (see Sources).

Green peas and green beans proteins promote satiety, decrease appetite, team up with fiber to slow down digestion, regulate blood sugar, and promote bone and muscle mass (see Sources).

Omega-3 fatty acid prevents inflammation and heart disease, while omega-6 fatty acid prevents rheumatoid arthritis, and treats nerve pain (see Sources).

Side Effects of Green Peas and Green Beans

Despite the many health benefits of green peas and green beans, there are possible side effects. They both contain phytic acid and lectins, which disrupt digestion and mineral absorption. Bloating and gas can occur. And since they are vitamin K-rich, individuals on blood thinners may want to avoid consuming them (see Sources).


Do green peas and green beans differ in their nutritional content? No and yes. They are both members of the legume family, so their nutritional profiles are only slightly different. Adding either vegetable to your diet will provide a myriad of health benefits.
