In the article How to Use Centered Alignments: Tips and Examples the following recommendations are suggested :
There’s nothing inherently bad about a centered alignment, you just have to know how to properly yield one if you’re going to implement it with any amount of success.
The first thing you need to learn is when not to implement a centered alignment. The answer here is pretty simple: when you have a lot of content.
It’s very important in any design to analyze your goals. If a significant degree of readability is one of them, and it often should be, then aesthetic appeal is often completely separate or even directly at odds with this goal. The trick is to find the balance between the two.
One of the first places you can start to think about implementing a completely centered layout is when you have very little content.
Make sure that, if your entire layout is built on a centered alignment, you have a very simple design with only a few items. Once you start adding big blocks of text and lots of images, the centered alignments starts looking messy. Also, try building a solid left, justified or even right alignment for your page as a whole, then experiment with selectively dropping in centered alignments in key areas such as headlines. Finally, as a quick trick when you’re in a jam, try wrapping center-aligned portions in a box that goes with the flow of the rest of the page.

This way the users won't be looking where the next line text starts because there is only 1 line of text.
Use left/right align for text with more than 1 line to assure best readability for long texts.
You could use justified text for aesthetic purposes, as well.
Well, given that centre aligned text would be difficult to read, you could use it sparesly for some short paragraphs, e.g. introductory paragraphs following a heading.
