No, "everything created by God is good, and nothing is to be rejected if it is received with thanksgiving". But at the same time, "the love of money is a root of all kinds of evil, for which some have strayed from the faith in their greediness, and pierced themselves through with many sorrows."

I think it's easier to be greedy for wealth than for health, so money is more dangerous, but both are good things if sanctified by prayer. At the same time, fasting is a common spiritual practice for a reason — we need to detach our overly-tenacious affections from this world and set our mind on things above, where Christ is.
