Pepper, capsicum, red, boiled in unsalted water

Red capsicum, also known as red pepper, is a vegetable. The figures here describe it boiled in unsalted water. It provides carbohydrate and fibre, along with vitamins and minerals, notably vitamin C. Per 100g, it contains 3.4g of carbohydrate, 2.4g of fibre, 89mg of vitamin C and 103µg of vitamin A, expressed as retinol equivalent.

Vitamin C supports normal collagen formation and helps the body absorb iron from plant foods. Fibre supports normal bowel function, while vitamin A contributes to normal vision. This preparation contains only trace amounts of salt; adding salt during cooking would change its salt content. Full nutrient figures are provided in the tables below.
