When it comes to describing food, the term "good tasting" is often used to convey how delightful and flavorsome it is. However, there are several antonyms that can be used to describe food that does not taste good. These include terms such as unappetizing or distasteful, which suggest that the food lacks flavor, texture, or just is not pleasing to the palate. Other words like bland, insipid, and tasteless can be used to describe food that is not flavorful, lacks spices or seasoning. In contrast, there are antonyms that suggest that the food is extremely unpleasant, such as repulsive, rancid, or putrid, which indicate that the food is not only tasteless but also off-putting and potentially harmful.
