Overview

About Bell pepper

Bell peppers, red, green, yellow or orange, are a nightshade, the same botanical family as tomatoes, potatoes, eggplant and chilli.

That is their one real trigger: they score high on nightshade sensitivity, so people who react to the glycoalkaloids in nightshades can get joint aches, digestive upset or skin flare-ups from any colour of capsicum. On every other axis the bell pepper is clean. It is low FODMAP, low histamine, low salicylate, low oxalate and genuinely anti-inflammatory, so if nightshades are not your problem it is one of the safer vegetables you can log.

How Bell pepper scores

Watch for

What trips people up

  • Nightshade, so it can trigger joint pain, gut symptoms or skin reactions in people sensitive to solanine and other glycoalkaloids
  • Colour does not change the family: red, green, yellow and orange bell peppers are all the same species (Capsicum annuum) and all count as nightshades
  • Green peppers are picked unripe and carry a bit more of the bitter glycoalkaloids than fully ripe red ones, so some nightshade-sensitive people find green the harshest

FAQ

Common questions about Bell pepper

Are bell peppers a nightshade?

Yes. Bell peppers are Capsicum annuum, part of the nightshade family alongside tomatoes, potatoes, eggplant and chilli peppers. They contain glycoalkaloids such as solanine, the compound most often blamed when nightshades trigger joint pain or gut symptoms. Sweet peppers hold far less of it than potatoes or green chillies, but they still count as a nightshade.

Does the colour of a bell pepper change whether it triggers me?

Not the family. Red, yellow, orange and green bell peppers are the same plant picked at different stages of ripeness, so all are nightshades. Green peppers are unripe and hold slightly more of the bitter glycoalkaloids, so a few people find green the most provoking, but if you react to nightshades no colour is truly in the clear.

Is bell pepper a problem for anything other than nightshade sensitivity?

Rarely. Bell peppers are low FODMAP in normal servings, low in histamine and salicylates, low in oxalate and anti-inflammatory, so outside of a nightshade reaction they are one of the gentler vegetables to eat.
