Before i totally thought that all the red meat was great for your body and a great protein source, well, later i saw in some news that yes, red meat is a great source of protein, but it also raises the chance of having cancer, so i still eat red meat but in a smaller quantity.
A meal I thought was terrible were burgers, but later on i was told that burgers are a lot better than other meals, so also i eat them, but in a low quantity too.
