Bell peppers come in three vibrant colors—green, yellow, and red—each representing different ripening stages of the same vegetable. Their nutritional content varies as they mature, influencing their flavor and health benefits.

Green bell peppers are unripe and rich in vitamin C, vitamin K, folate, and fiber, which promote gut and heart health and aid in weight management. About 150 grams of raw green peppers provide 2.5 grams of fiber.

Yellow bell peppers represent a moderate ripening stage, containing high levels of vitamin C (126 to 159 mg per pepper), vitamin A, beta carotene, and antioxidants. They boost immunity, support eye health, maintain skin health, and assist digestion.

Red bell peppers are fully ripe and rich in vitamin A, vitamin C, potassium, and lycopene—a potent antioxidant good for heart and skin health. Their nutrient density supports strong immunity and improves vision.

While each color offers unique and overlapping nutritional benefits, red peppers are richest in lycopene, yellow peppers have the highest vitamin C, and green and red peppers have slightly lower levels comparatively. Incorporating all three colors in your diet is the best way to maximize health benefits from bell peppers.
