Definition: Non-nutritiously is a term used in the field of nutrition to describe foods that are not as nutritious or high in nutrients as they should be. Non-nutritious foods are often associated with poor health outcomes, such as obesity and diabetes, because they lack essential vitamins, minerals, antioxidants, fiber, and other nutrients. These foods can also contain added sugars, saturated or trans fats, or unhealthy amounts of salt, which can contribute to overall health problems.
