Green chillies are definitely more suitable than red chillies powder. As a spice may be healthy for many people, while those who experience digestive distress should avoid them. Green chillies also have water content and no calories which make them a healthy choice for raw consumption as well as cooking. Green chillies are also richer in beta carotenes, antioxidants and endorphins while red chillies are considered as a cause of peptic ulcers. The chances of artificial dyes and colours being used in store bought red chilli powders is also high.
So spicy green chili powder nice quality.
