How Do Diabetics Know What Foods to Avoid in Restaurants?

Diabetics should avoid eating simple carbohydrates, saturated fats, trans fats, cholesterol and foods high in sodium, according to WebMD. When eating at a restaurant, diabetics should choose menu items that are fiber-rich, contain monounsaturated or polyunsaturated fats, or fish high in omega-3 fatty acids.

Diabetics needs to carefully monitor their eating habits to avoid insulin spikes. Fried and high-fat starches, such as potato chips and french fries, should be avoided. Instead, a diabetic should opt for whole-grain breads. Vegetables served without dressing and cooked with no fat are also recommended for diabetics. Low-fat diary is also acceptable. Meats, including fish, are acceptable menu items so long as they are low in fat, states the National Institute of Diabetes and Digestive and Kidney Diseases.

Diabetics need to avoid foods high in sugar. Soft drinks, fruit-flavored drinks and hot beverages sweetened with sugar are unacceptable for a diabetic diet. Additionally, diabetics should not eat canned soups, canned vegetables, pickles and processed meats, reports the Centers for Disease Control and Prevention.

There are three types of diabetes that affect humans: Type 1, Type 2 and gestational diabetes. People who suffer from Type 1 diabetes are not able to make enough insulin because the body has destroyed insulin-producing cells. Type 2 diabetes involved the pancreas. The pancreas of Type 2 diabetics is unable to produce enough insulin when blood sugar rises. Gestational diabetes occurs during pregnancy. Sometimes the hormones produced by pregnancy cause gestational diabetes, or there is less insulin produced during pregnancy, according to NIHSeniorHealth.
