Improving is definitely -ier. -y denotes a state, -ier denotes movement towards that state, but not necessarily being in that state. Improving implies movement. Some might view the -ier style statements as weasely or waffling, but it's also the most responsible way to describe most foods in my opinion, as there's often just a matter os scale that tips something from healthy to not (or outright dangerous, even). An orange is a healthy snack if you can make use of the vitamin C and don't already have an overabundance of sugar. If you don't need vitamin C or already consume a lot of sugar, there are probably better sources of vitamin C and an orange might not really be a healthy choice.
