Plantain: Nutrition Facts and Health Benefits

Plantains (Musa × paradisiaca) are a starchy, low-sugar member of the banana family that are almost always cooked before eating, in contrast to the sweet dessert banana. They are a fundamental staple food across much of West and Central Africa, the Caribbean, Central America, and parts of South America and Southeast Asia. Though closely related to bananas, plantains are larger, starchier, and contain much less sugar, making them nutritionally more similar to a root vegetable or grain than a fruit in their culinary role.

Nutritional Value of Plantain

Plantains contain 122 kcal and 1.7 g of fibre per 100 g. They are primarily a carbohydrate food, providing 31.9 g of carbohydrates per 100 g, a significant portion of which is starch in unripe fruit. As plantains ripen and their skin turns yellow then black, starch gradually converts to sugar, increasing sweetness. They are a good source of vitamin B6, which is important for protein metabolism, neurotransmitter synthesis, and immune function. Plantains also provide vitamin C, potassium, magnesium, and vitamin A as beta-carotene. They are low in fat and provide moderate protein.

Health Benefits of Plantain

Plantains are a significant source of resistant starch when unripe, which acts as a prebiotic fibre, feeding beneficial gut bacteria and supporting digestive health. The vitamin B6 in plantains is particularly notable — it plays a role in over 100 enzyme reactions in the body and is important for immune function. Potassium supports healthy blood pressure and heart function. Plantains are a good source of sustained energy due to their complex carbohydrate content, which is why they feature as a staple in many food cultures. Unlike refined carbohydrates, the fibre and starch in plantains moderate the pace of glucose absorption.

How to Select and Store Plantains

Plantains are typically sold in varying stages of ripeness. Green plantains are firm, starchy, and savoury. Yellow plantains are semi-ripe, softer, and slightly sweet. Black-skinned plantains are fully ripe and sweet. Choose the stage of ripeness appropriate for your recipe. Green plantains can ripen at room temperature over several days. Ripe plantains can be refrigerated for a few days. Cooked plantain freezes well.

How to Use Plantains

Green plantains are fried to make tostones (twice-fried chips), boiled in soups and stews, or ground into flour. Yellow plantains are fried as a side dish or used in hearty stews. Ripe black plantains are sweet enough to caramelise in a pan with oil and are served as a dessert or side dish across the Caribbean and West Africa. Plantain can also be baked, roasted, grilled, or mashed.
