As the name implies, instant coffee, or three-in-one coffee, is composed of at least three ingredients: instant coffee powder and non-fat sugar (many brands also add coffee essence, etc.), and the proportion of sugar in the ratio is also very high, so it will be fat. In addition, at present, the non-dairy creamer in instant coffee basically contains trans fatty acids, which is not good for the body, so try to drink less. If you like coffee, you can choose freshly ground coffee, which is not expensive.
