"Non-dairy" is a term used to describe products that do not contain any animal-derived dairy products. However, there are several synonyms that can be used to describe such products, depending on the context in which they are being used. Some of the commonly used synonyms for "non-dairy" include plant-based, dairy-free, vegan, and lactose-free. These terms are often used interchangeably, although they may have slightly different meanings, such as "vegan" which denotes that a product is free from all animal products, not just dairy. Regardless of the synonym used, it is important to remember that non-dairy products provide alternatives for individuals with dietary restrictions or ethical concerns about consuming animal products.
