If you have diabetes, there are certain foods that you should avoid eating no matter how much you want them. They are full of sugars that can put a strain on the body. This strain can lead to higher levels of blood sugar, which can lead to passing out or being on more insulin in order to maintain the sugar levels. There are some foods that come in a sugar-free version so that you can enjoy the flavors.
Although this isn't a food, it's something that you shouldn't consume. Sodas are full of caffeine and sugars.
There are diet drinks that don't have as high of a sugar content, but they should still be avoided if possible. Water is ideal for those with diabetes as it can help to flush out the kidneys and the rest of the body, getting rid of excess sugar in the process.
