Curry Powder
Curry leaves are green, but curry powder is made up of a variety of spices, including turmeric. Turmeric has anti-inflammatory effects, which is why it may be found in a variety of health foods, including smoothies and supplements. Turmeric has a vivid orange color when raw, and it stains your fingers a yellow-orange tint if you've ever touched it. Turmeric takes on a more yellow color when dried and ground into a powder.
Cooking with curry powder and turmeric adds a lot of flavors, but it might turn your teeth yellow over time. Curry should be kept to a minimum in your diet due to its strong staining factor. Drink plenty of water or rinse your teeth after eating curry to avoid the curry powder sticking to your teeth for too long.
