**Semantic type:** Classification

**Definition:** Used for projects involving any aspect of diet or dietary components or contaminants; or food production, packaging, storage, or preparation in relation to health effects, whether positive or negative. Dietary components include drinking water, alcoholic beverages, and vitamin and trace element supplements.
