Look online to find common replacements for cooking ingredients which aren’t good for a Diabetic. For example, fruit can be used in place of sugar, as in a sugar free banana bread or muffins. You can also use whole grain flours instead of bleached, or buckwheat instead of rice in a dish.
If you have diabetes, you should try to cut out alcohol or talk to your doctor if you can not. Alcohol can cause low blood sugar, which is called hypoglycemia. The effects can be very hard to predict with different people. Doctors will allow some people to have a drink or two with proper management, but it is best to avoid alcohol altogether.
