Kostbaserte

Kostbaserte is a Norwegian adjective used to describe something that is based on diet or nutrition. It is commonly found in nutrition science, public health, and clinical practice to denote interventions, analyses, or guidelines that derive their rationale from dietary factors rather than other determinants.

The term is formed from kost, meaning food or diet, and basert, meaning based. It is distinct from kostnadsbasert (cost-based), which uses the root kostnad meaning cost. The two terms are not interchangeable, and using the wrong form can lead to confusion about whether diet or cost is being emphasized.

Typical contexts include kostbaserte intervensjoner (diet-based interventions) aimed at modifying nutritional intake or eating patterns, and kostbaserte anbefalinger or retningslinjer that derive from evidence about dietary exposures. In research design, a kostbasert study would examine outcomes linked to dietary factors rather than economic or other factors.

Notes for readers: the term is mainly used in Norwegian-language texts; translations should consider the intended emphasis to avoid conflating with cost-based terminology. When writing for bilingual audiences, it can be helpful to provide the English equivalent in parentheses on first use, e.g., diet-based (kostbaserte) interventions.
