nourish

Hello,

I would like to know if the following sentence is correct:

If I could, I would nourish myself on potatoes.

Thank you for your help.[/u]

It doesn’t sound natural. More context is needed to find the best alternative. For example, “If I could, I would live on potatoes” means that you would like all (or, more loosely, most) of your diet to consist of potatoes.
