Tips that are delivered to you will naturally come in marked as 'unread'.  You can view these tips by clicking on each of the images, which will take you to the tip page.

After you have read a particular tip, you can mark it as 'read' by pressing on the 'eye' button in the top right hand corner of the tip.

If you find a certain tip particularly interesting or you think you may wish to come back and read it again at a later time, you can nominate it as a favourite.

Both unread and favourite tips are displayed on the Today screen Healthy Tips widget.
