Did you know that 68 percent of processed foods at the grocery store contain added sugar? This statistic cited by The Lancet could alarm anyone — but especially if you've got diabetes and are trying to stay on top of your glucose levels. If you are looking for a sugar substitute to curb your sweet tooth as you manage your diabetes, there are actually a number of options — some of which can be grown right in your backyard. That means you can now have your cake and eat it, too — all without spiking blood sugar levels. As you check out the five ideas here, keep in mind that some sugar substitutes work better for baking, while others might be tastier in your coffee. Of course, it's important to keep track of how your body reacts to these, so you can choose the one that works best for you. As always, consult a medical professional, such as a physician or registered dietitian, before modifying your diet or insulin use.
