Synonymous expressions

Question

This type of exercise is my favorite, where there is an almost one-to-one equivalence between the English and French words and groups of words for translation. I have two small questions. 
1. To denote nutritious, can we say: nutritif or nutritive?
2. To denote recover, can we say: se rétablir ainsi que récupérer?
 
Thanks!

Bonjour Blaise,
It's true that it makes it easier when trying to translate in French.
1.  Nutritif is used when talking about the quality of a food
C'est un aliment nutritif = It is a food rich in nutrients
 Nutritionnel is used when talking about the general process/study of nutrition
Cette maladie est due à une carence nutritionnelle = This illness is due to a nutritional deficiency
2. "récupérer" is already an option for "to recover". In this context, "se rétablir" does not fit because it means to recover from an illness, injury or a state of poor health. take a look here: se rétablir 
I highly suggest you use a bilingual dictionary such as Wordreference or Collins among others for such queries.
I hope this is helpful.
Bonne journée !
