Red bell peppers are considered the healthiest variety due to their higher nutrient content compared to green and yellow peppers. Here's a breakdown of the key differences:
Ripeness: Red peppers are the most mature, having been left on the vine longer than green and yellow peppers. This allows them to develop more nutrients.
Vitamin A: Red peppers contain the most beta-carotene, a precursor to vitamin A. Beta-carotene levels increase as peppers ripen.
Vitamin C: Red peppers are an excellent source of vitamin C, with one medium pepper providing over 150% of the RDI. Yellow peppers actually contain the highest vitamin C levels.
Antioxidants: Red peppers are rich in antioxidants like lycopene and capsanthin, which give them their deep red color. These compounds provide anti-inflammatory benefits and may reduce disease risk.
Flavor: Red peppers are the sweetest, while green peppers have a more bitter, grassy taste. Yellow and orange peppers fall somewhere in between.
However, all bell peppers are highly nutritious, providing fiber, B vitamins, vitamin K, and minerals like potassium
