There's an area in the game where you can acquire all the red fruit you'll ever need to max out your stats.

In the Soaring Tower level (where you find the Forest Of Knowledge), there's an area where ten Bashguds will appear out of thin air. Each time you defeat one you'll get a red fruit.

Then, return to the lower level of the tower and enter the Save Crystal Shopping Area. Exit and go back up to where you found the Bashguds. Ten more should appear. Keep doing this until you've maxed out your stats.
