Is there any difference–nutritionally or otherwise–among red, green and yellow bell peppers?
Excellent question — and yes, there are meaningful nutritional and phytochemical differences among red, green, and yellow bell peppers, even though they’re all the same species (Capsicum annuum) at different ripening stages.
Here’s a detailed comparison:
🫑 1. Green Bell Peppers — Immature stage
-
Ripeness: Picked before full maturity.
-
Taste: Slightly bitter, grassy, less sweet.
-
Nutrients:
-
Vitamin C: About 95 mg per 100 g (still high).
-
Carotenoids: Low; mainly chlorophyll (which gives them their color).
-
Flavonoids: Higher in certain phenolic compounds (antioxidants that protect against inflammation).
-
Vitamin A (as β-carotene): Very little.
-
Folate & Vitamin K: Present in modest amounts.
-
-
Other notes:
-
Slightly higher in polyphenols and chlorogenic acid, giving them stronger detox and liver-supportive effects.
-
Can be harder to digest for some people due to higher alkaloid content.
-
🩺 Best for: liver cleansing, chlorophyll intake, early-phase detox protocols.
🌕 2. Yellow (or Orange) Bell Peppers — Intermediate stage
-
Ripeness: Partially ripened.
-
Taste: Milder, a bit sweet and less bitter.
-
Nutrients:
-
Vitamin C: ~120 mg per 100 g — highest among the three.
-
Carotenoids: Especially lutein and zeaxanthin (important for eye and macular health).
-
Vitamin A: Rising levels as carotenoids increase.
-
Antioxidants: Balanced—mix of chlorophyll (still some green) and carotenoids.
-
-
Other notes:
-
A good midpoint between the cleansing effects of green peppers and the high-antioxidant profile of red peppers.
-
🩺 Best for: eye protection (lutein/zeaxanthin), immune support, and overall antioxidant balance.
🔴 3. Red Bell Peppers — Fully ripe stage
-
Ripeness: Left on the plant to mature completely.
-
Taste: Sweetest, mildest, richest flavor.
-
Nutrients:
-
Vitamin C: ~150 mg per 100 g — more than 2× an orange.
-
Vitamin A: 9× higher than in green peppers due to β-carotene.
-
Lycopene: Present (same pigment as in tomatoes), linked to heart health and cancer protection.
-
Antioxidants: Highest overall; particularly capsanthin, a potent red carotenoid.
-
-
Other notes:
-
Easier to digest; promotes collagen formation and immune strength.
-
Strong synergy with Vitamin E and Omega-3s for skin and vascular health.
-
🩺 Best for: skin repair, eye health, cardiovascular protection, immune defense.
🔬 Summary Table:
| Nutrient / Property | Green | Yellow/Orange | Red |
|---|---|---|---|
| Ripeness | Immature | Mid | Fully ripe |
| Vitamin C (mg/100 g) | ~95 | ~120 | ~150 |
| Vitamin A (β-carotene) | Low | Moderate | High |
| Lutein + Zeaxanthin | Moderate | High | Moderate |
| Lycopene | — | — | High |
| Chlorophyll | High | Moderate | Low |
| Taste | Bitter | Mild | Sweet |
| Digestibility | Lower | Medium | High |
🌿 In your context (detox, kidney, eye, and circulation focus):
-
Green peppers: Useful during detox or fasting phases for chlorophyll and mild bile stimulation.
-
Yellow peppers: Ideal for your eye recovery phase — rich in lutein/zeaxanthin.
-
Red peppers: Excellent for ongoing vitamin C and collagen support — helps wound healing and vascular tone.
