I came across Nutrition Information on the back of a packet of crisps recently and wondered if this should be Nutritional Information? Which is correct and what's the difference in meaning between the two?
"Nutrition Information" is correct. In this case "Nutrition" is a noun adjunct, meaning a noun has been used as an adjective. This is very common in English. For example, say "chicken soup" instead of "soup of chicken".
In fact, nearly any noun can be an adjective.
- If you are going to a show about cars, you can call it a "car show".
- If you refer to the slide on a trombone, call it a "trombone slide".
- A device used to open cans is a "can opener".
"Nutritional Information" is not necessarily improper grammar, but it sounds like "information that provides nourishment" rather than "information about nutrition". For example, you eat a "nutritional snack" if you are hungry, but you read a "nutrition book" to learn about nutrition.
Yes, formally it should be nutritional information.
Nutrition is a noun and nutritional is the adjective. Since we are describing information, we should use the adjective.
Though nouns are used as adjectives in some cases, this isn't one of those cases. Here are some examples of nouns used as adjectives.
