Yellow bell peppers are also low in calories and can be a great snack if you are on a diet.
Which one is best?
Bell peppers come in a variety of colors, each offering its own unique health benefits. While green, red, and yellow bell peppers are popular choices, red bell peppers are often considered the best choice. This is because they have the highest nutritional content compared to the less mature green and yellow bell peppers.
“Red bell peppers are known for their sweeter flavor and are rich in important vitamins and antioxidants, especially vitamin C. They also contain significant amounts of beta-carotene, which supports eye health.
However, it's worth noting that yellow bell peppers actually contain the highest amount of vitamin C of the three colors, making them a great choice for boosting your intake of this nutrient,” says Dr. Batra.
