The cheapest bell peppers are usually green ones. According to Matt Fowler, manager of the produce category at Natural Grocers, "green bell peppers are the least ripe and have a distinct grassy, slightly bitter taste."
In terms of flavor and nutritional value, bell peppers that are yellow and orange fall somewhere in the middle. "They offer a nice middle ground with a gentle sweetness and crisp texture," Fowler explains.
Of all the bell peppers, red bell peppers have the highest nutritional content. "Specifically, they are highest in vitamin C, A, and lycopene," according to Kenney. All of these are potent antioxidants that promote immunological function, lower inflammation, and guard against heart and prostate problems.
Red peppers top the nutrient charts because they have more time to absorb nutrients from the soil and mature, claim Murphy and Kenney. "Go for red if you want the healthiest option," suggests Kenney.
Think about your preferred flavor and taste as well as how you want to prepare them when selecting which bell peppers to purchase.
Green peppers are the best option if you want a stronger flavor or a touch of bitterness. According to Fowler, orange, yellow, or red bell peppers are excellent options for recipes that call for a burst of color or sweetness.
