Bell peppers: A colorful superfood for vibrant health

• Bell peppers are rich in vitamins C, A, B6, K1 and antioxidants like lycopene and zeaxanthin, supporting immunity, eye health and heart function.
• Red peppers (fully ripened) are sweeter and more nutrient-dense than green ones. Each color offers unique flavors – green is slightly bitter, while yellow/orange are fruity.
• Native to Central and South America, bell peppers spread globally via Spanish and Portuguese explorers. Today, China, Mexico and the U.S. are the top producers.
• Rare nightshade sensitivities may occur. Conventionally grown peppers often carry pesticide residues; opt for organic or wash thoroughly.
• Enjoy bell peppers raw in salads, roasted for sweetness, grilled for smokiness or stuffed or sautéed. Key dishes include fajitas, ratatouille and hummus.

Bell peppers (Capsicum annuum), with their vibrant colors and crisp texture, are more than just a culinary delight – they are a powerhouse of nutrition. Whether red, yellow, green or orange, these sweet, crunchy vegetables offer an impressive array of vitamins, antioxidants and health benefits.

Bell peppers are a vibrant and versatile member of the nightshade family, closely related to chili peppers, tomatoes and eggplants. Unlike their spicy counterparts, bell peppers contain little to no capsaicin, giving them a mild, sweet flavor rather than heat.

Native to Central and South America, bell peppers have a rich history dating back at least 7,000 years, with evidence of cultivation in regions like Mexico, Bolivia and Peru. Spanish and Portuguese explorers introduced them to Europe in the 15th and 16th centuries, sparking their global spread. Thanks to their adaptability to different climates, bell peppers thrive in both tropical and temperate regions, leading to rapid cultivation and integration into diverse cuisines. By the 18th century, they had reached Asia and Africa, becoming a staple ingredient worldwide.

Today, China, Mexico and the United States rank among the top producers of bell peppers. Available in a spectrum of colors – green, red, orange and yellow – each variety offers distinct flavors, from slightly bitter (green) to sweet and fruity (red, the ripened version of green). Their widespread popularity continues to make them a beloved ingredient in countless dishes across cultures. (Related: Study looks at the potential of red peppers as a natural anti-inflammatory agent.)

Nutritional profile and health benefits

Bell peppers stand out as one of the most nutrient-dense vegetables, offering an impressive array of vitamins, minerals and antioxidants with minimal calories. Their rich nutritional profile makes them a versatile and health-boosting addition to meals. Below are the key nutrients that make bell peppers a superfood:

• Vitamin C – A single red bell pepper provides 169 percent of the daily value (DV), more than one whole orange. This powerful antioxidant strengthens the immune system, promotes collagen production for healthy skin and enhances iron absorption. Regular consumption can help reduce oxidative stress and support wound healing.
• Vitamin A (beta-carotene) – Essential for maintaining vision, immune function and skin repair, beta-carotene converts to vitamin A in the body. It also acts as an antioxidant, protecting cells from oxidative damage and reducing the risk of chronic diseases. Red bell peppers, in particular, are loaded with this vital nutrient.
• Vitamin B6 and folate – These B vitamins play a crucial role in brain health, energy metabolism and red blood cell production. Folate is especially important for pregnant women, as it supports fetal development, while vitamin B6 helps regulate mood and cognitive function.
• Vitamin K1 – Critical for blood clotting and bone health, vitamin K1 ensures proper calcium absorption and reduces the risk of osteoporosis. Including bell peppers in your diet can help maintain strong bones and support cardiovascular health.
• Fiber – Bell peppers contain dietary fiber, which aids digestion, promotes gut health and helps regulate blood sugar levels. Fiber also contributes to satiety, making them an excellent choice for weight management.
• Antioxidants (chlorogenic acid, caffeic acid, zeaxanthin) – These compounds combat oxidative stress, reduce inflammation and protect against chronic diseases. Zeaxanthin, in particular, supports eye health by shielding against age-related macular degeneration. (Related: Study looks at the potential of red peppers as a natural anti-inflammatory agent.)

Choose organic bell peppers

There are a few considerations to keep in mind when eating bell peppers.

Some individuals with autoimmune conditions may experience sensitivity to nightshades, though this is rare. Another concern is pesticide residue, as conventionally grown bell peppers frequently appear on the Environmental Working Group’s (EWG) “Dirty Dozen” list due to traces of chemicals like imidacloprid (linked to bee decline), chlorpyrifos (a neurotoxin banned in some countries) and acephate (a potential carcinogen). While bell peppers are not typically high in heavy metals, soil contamination in certain regions could pose a risk.

For optimal safety, choosing organic bell peppers is recommended. If unavailable, thorough washing with baking soda or vinegar can help reduce pesticide residues.

Raw peppers are high in vitamin C, making them ideal for fresh salads and crunchy snacks. Roasting enhances their natural sweetness and depth of flavor, making them perfect for soups, dips or roasted vegetable medleys. Grilled peppers develop a smoky char that pairs beautifully with kebabs, sandwiches or fajitas.

For a balanced approach, gently sauté bell peppers to preserve their crunch and release more beta-carotene. If you prefer a softer texture, try grilling them until blackened, then steaming them in a sealed bag to easily remove the skin.
