The Health Benefits of Bell Pepper: Nature’s Colorful Superfood

 Introduction

            Bell peppers (Capsicum annuum), often called sweet peppers or capsicums, are vibrant, versatile, and nutrition-packed vegetables that brighten dishes with their bold colors red, yellow, orange, green, and even rare purple or white varieties. Unlike their spicy cousins in the chili pepper family, bell peppers have little to no capsaicin, the compound that gives chili peppers their heat. This makes them naturally sweet, crisp, and appealing to people of all ages.

            Bell peppers have been valued for thousands of years, not only for their culinary versatility but also for their health-promoting properties. Today, nutrition scientists and dietitians recommend them for boosting immune health, eye protection, skin vitality, heart function, weight management, and much more.
