Many question the quote: "You are what you eat", this is only if they take the saying too literally. It does not mean that you will become the food you eat itself. It means you can represent the food you eat by your appearance, behavior, healtg. etc.

Also, it is telling us to always be aware of our food intake, whether it's street food, fast food, or groceries. Some of them may be unhealthy especially if they are fake ripoffs or copies of other brands, or if the source of manufacturing is unknown. These are signs to take heed in buying whatever food from small candies to fast food meals.
