Bell peppers deliver powerhouse health benefits like boosting immunity with over 150% daily vitamin C per cup, supporting eye health via lutein and zeaxanthin, promoting heart health by lowering blood pressure, aiding digestion with 2.5 grams of fiber, enhancing iron absorption, and providing antioxidants that fight inflammation and cancer risk-all while being low-calorie at just 30 per serving.
Nutritional Powerhouse
Bell peppers, scientifically Capsicum annuum, pack exceptional nutrient density across colors: red offers 213mg vitamin C, orange 237mg, yellow 208mg, and green 149mg per cup, exceeding oranges. This vitamin C arsenal, combined with vitamin A (13% DV), B6 (20% DV), folate (10% DV), and fiber (1-3g), fuels immunity, collagen production, and metabolic health. Doctors value them for bioavailability-pairing naturally with iron sources to combat anemia.
- 190% DV vitamin C in red varieties supports wound healing and iron uptake.
- High beta-carotene converts to vitamin A, protecting vision and skin.
- 2.5g fiber per cup promotes satiety and gut microbiome balance.
- Anthocyanins in red peppers link to cognitive protection against age-related decline.
- Potassium regulates blood pressure; one pepper provides 8% DV.
Historical context: Native to Central America since 5000 BCE, bell peppers spread globally post-Columbus in 1493, evolving sweeter varieties by the 1700s for medicinal use in Europe.
