Garlic's benefits are vastly overstated due to a rumor that has spread like wildfire since a respected aquarist suggested that it MIGHT be helpful in the treatment of internal parasites. That being said it can't hurt to use it.
Live food is by far the best for some fish but is really difficult to deal with.
Like was previously stated home made fish food made from fresh fish bought from the store is the most nutritious but can potentially contain parasites.
There are a number of parasite free frozen fish foods that can be bought at a fairly affordable price as well.
Then bringing up the rear is the freeze dried, flake, and pellet foods; which should all be fairly equivalent in their nutritional content.
For herbivores there are plenty of different macro algaes you can grow that are very nutritious and will help clean your tank.
