Green chilli is a fruit pod, and is an indispensible ingredient of a majority of Indian diets. This spice is grown throughout the year - hence, there is no scarcity. Green chilli is rich in vitamins A and C. It also has vitamin B1, B2, and B3, besides vitamin B9 (folate). As for minerals are concerned, it has a lot of magnesium, iron, zinc, phosphorus, and calcium. One cup of green chillies (or about 80 grams) can provide our body 23 calories of energy, about 3 grams of protein, about 2.5 gram of carbohydrate, over 5 gram of fiber, and a very tiny amount (.5 gram) of fat.
