A Diabetic diet can include many "bad" foods as long as you reduce your portions. MANY studies have shown that people who live to a hundred eat a diet that is very restrictive on calories. This leads them to have healthy organs, strong minds, and a long, happy, vigorous life.
Diabetics who notice that their fingernails and toenails are becoming very thick and even pulling away from the nail bed may actually have a fungal infection. Fungal infections are more common in people with diabetes; diabetes may also make them more likely to suffer liver damage from common anti-fungal medications. If your doctor prescribes an oral medication, be sure to have regular blood work during therapy.
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.
