Bell Pepper
Colorful Vitamin C Source
What is this ingredient?
All bell peppers start green and ripen to yellow, orange and finally red. This ripening process significantly increases vitamin C and beta-carotene content. Red bell pepper contains up to 3x more vitamin C than green bell pepper.
Expert Tip: For the most nutritional value, choose red bell pepper. For a milder taste or crunchiness in dishes, green bell pepper also works fine.
How does it taste?
Sweet, juicy and mild with a bright, fruity flavor. Roasting adds smokiness.

Good Combinations (Synergy)
Combine bell pepper smartly to enhance the effect:
Vitamin C increases iron absorption from lentils up to 6x
Technical: Beluga lentils contain 8mg non-heme iron per 100g — one of the highest levels among legumes. Non-heme iron in Fe³⁺ form is barely absorbed (5-12%). Bell pepper contains up to 128mg vitamin C per 100g (red pepper) that reduces Fe³⁺ to Fe²⁺, the bioavailable form. This can increase iron absorption by 400-600%.
What does this mean for you? Always add colored bell pepper to your lentil dishes — dice them raw into a warm lentil salad or cook them into a stew. Red pepper is most effective due to the highest vitamin C content.
6x better iron absorption through vitamin C
Technical: Steak contains 2.6mg heme iron per 100g — the most absorbable form of iron (15-35% absorption vs. 5-12% for non-heme). Yet vitamin C from bell pepper (128mg per 100g red pepper) can further increase total iron absorption by also activating non-heme iron in meat and stimulating ferroportin expression. Studies show 3-6x higher total iron uptake.
What does this mean for you? Add bell pepper to your steak — as salad, roasted side dish or in a stir-fry. Red pepper has the most vitamin C, but yellow and green work too. Perfect for athletes and iron deficiency.
Fats in hummus increase beta-carotene absorption 4x
Technical: Hummus contains tahini (sesame fat) and olive oil — two fat sources that increase carotenoid absorption. Carrot contains 8285μg beta-carotene, bell pepper 2094μg — both fat-soluble with only 5-10% absorption without fat. The fat in hummus increases beta-carotene absorption up to 4x, making more provitamin A available.
What does this mean for you? Dip carrots and bell peppers in hummus as a snack. The fats from tahini and olive oil in the hummus ensure you get 4x more vitamins from the vegetables.
Vitamin C enhances iron absorption from turkey meat
Technical: Turkey mince contains heme iron (approx. 1.4mg/100g) absorbed at 15-35%, plus non-heme iron that is poorly absorbed. Vitamin C from bell pepper (128mg/100g red pepper) reduces non-heme iron from Fe³⁺ to the bioavailable Fe²⁺ form and stimulates ferroportin expression. Additionally, turkey provides B6 (0.5mg/100g) supporting hemoglobin synthesis — giving the iron a direct destination.
What does this mean for you? Cook turkey mince with bell pepper for an iron-rich meal. The vitamin C from pepper maximizes iron absorption, while B6 from turkey directly deploys the iron for oxygen transport.
Vitamin C increases iron absorption from kidney beans up to 6x
Technical: Kidney beans contain 2.9mg non-heme iron per 100g (cooked). Non-heme iron in Fe³⁺ form is poorly absorbed (5-12%). Bell pepper contains up to 128mg vitamin C per 100g (red pepper) that reduces Fe³⁺ to Fe²⁺, the bioavailable form. Additionally, vitamin C neutralizes phytates in beans that inhibit iron absorption. This can increase iron uptake by 400-600%.
What does this mean for you? Always add bell pepper to your chili or bean salad. Good to know: vitamin C increases iron absorption (EFSA-approved).
Vitamin C increases iron absorption from chickpeas
Technical: Chickpeas (base of hummus) contain 2.9mg non-heme iron per 100g with high phytate concentration. Red bell pepper provides 128mg vitamin C per 100g — the highest of all vegetables. This reduces Fe³⁺ to Fe²⁺ and completely overcomes phytate inhibition. The combination increases iron absorption by factor 4-6.
What does this mean for you? Dip red bell pepper strips in hummus — this isn't just a popular snack but also nutritionally optimal. The pepper provides the vitamin C needed to absorb iron from the chickpeas. Yellow pepper also works well (183mg vitamin C).
Vitamin C increases iron absorption from merguez 3x
Technical: Merguez (North African lamb sausage) contains 2.5mg heme iron per 100g with high bioavailability (15-35%). The spices in merguez (harissa, cumin, coriander) already contain some antioxidants. Bell pepper adds 128mg vitamin C per 100g that further increases iron absorption and also activates non-heme iron. Tomato provides lycopene (protects fat oxidation) plus organic acids.
What does this mean for you? Serve merguez with grilled bell pepper and tomatoes — exactly as in North African cuisine. The vegetables increase your iron absorption and offer antioxidant protection when grilling the sausage. Classic in couscous royale and shakshuka.
Vitamin C from bell pepper increases iron absorption from mung beans up to 4x
Vitamin C increases non-heme iron absorption and overcomes phytate inhibition (PMID: 2507689)
Technical: Mung beans contain 1.4mg iron per 100g cooked, but also phytic acid that blocks mineral absorption. Red bell pepper contains 128mg vitamin C per 100g (213% RDI!) which reduces Fe³⁺ to the more absorbable Fe²⁺. Additionally, vitamin C forms chelates that bypass phytate binding. Studies show 3-4x higher iron absorption.
What does this mean for you? Always add colored bell pepper to dishes with mung beans — think stir-fries, salads or curries. That extra pepper makes the difference between 'I eat healthy' and 'my body actually absorbs those nutrients'.
Fat improves carotenoid absorption from bell pepper
Technical: Red bell pepper contains 3131μg beta-carotene and 51μg lutein per 100g, plus 127mg vitamin C (211% RDI). Carotenoids are fat-soluble — without fat only 3-5% is absorbed. Olive oil increases bioavailability to 15-20% through micelle formation in the small intestine.
What does this mean for you? Roast bell pepper with olive oil or make a salad with olive oil dressing. Red pepper contains 10x more carotenoids than green — choose red for maximum effect.
Fat from nut butter increases carotenoid absorption by 3-6x
Technical: Carotenoids (beta-carotene, lutein, lycopene) in vegetables are fat-soluble and poorly absorbed without fat (5-10%). Nut butters contain 50-60g fat per 100g. Just 3-5g fat (1 tablespoon nut butter) increases carotenoid absorption to 30-60% — a 3-6x improvement. This applies to carrot, bell pepper, spinach and other colorful vegetables.
What does this mean for you? Dip veggie sticks in peanut butter or almond butter. The fat from the nut butter ensures your body absorbs 3-6x more vitamins from the vegetables.
Vitamin E enhances vitamin C recycling for longer antioxidant action
Technical: Sunflower seeds contain 35mg vitamin E per 100g (233% RDI) — the highest concentration of all seeds. Bell pepper provides 128mg vitamin C per 100g (160% RDI). Vitamin E and C work in a redox cycle: vitamin C regenerates oxidized vitamin E (tocopheryl radical → tocopherol) via ascorbate-dependent reduction. This extends antioxidant duration by 40-60%. Sunflower seeds also provide selenium (53μg/100g) activating glutathione peroxidase.
What does this mean for you? Sprinkle sunflower seeds over a bell pepper salad. Vitamin E and C recycle each other — you get longer-lasting antioxidant protection than from either alone. Perfect for skin health and immune system.

Bell peppers were cultivated in Central America for over 7500 years. After the Spanish conquest, peppers spread to Hungary, where they became a national symbol.
Summary
Bell peppers are versatile and rich in vitamin C. Color matters: red pepper is most nutritious, green is least sweet. Combine with a fat source for better carotenoid absorption.
