Questions & Answers about La fruta es muy sana.
Why is there a La at the beginning if the English translation is just 'Fruit'?
In Spanish, when you talk about a general category or concept, you must include the definite article (el, la, los, las). English drops the word 'the' when talking about fruit in general, but Spanish requires it, so we say La fruta.
Why do we use es instead of está here? Isn't health a condition?
Why does the word for healthy end in an 'a' (sana)?
Adjectives in Spanish must match the gender and number of the noun they describe. Because fruta is a feminine, singular noun, the adjective sano changes its ending to match, becoming sana.
