Fasting plasma glucose test (FPG): The preferred method of screening for diabetes. The FPG measures a person's blood sugar level after fasting or not eating anything for at least 8 hours. Normal fasting blood glucose is less than 100 milligrams per deciliter or mg/dL. A fasting plasma glucose greater than 100 mg/dL and less than126 mg/dL implies that the person has an impaired fasting glucose level, but may not have diabetes. A diagnosis of diabetes is made when the fasting blood glucose is greater than 126 mg/dL and when blood tests confirm abnormal results. These tests can be repeated on a subsequent day or by measuring glucose 2 hours after a meal. The results should show an elevated blood glucose of more than 200 mg/dL.
Fats: Substances that help the body use some vitamins and keep the skin healthy. They are also the main way the body stores energy. In food, there are many types of fats; saturated, unsaturated, polyunsaturated, monounsaturated, and trans fats. To maintain your blood cholesterol and triglyceride (lipid) levels as near the normal ranges as possible, the American Diabetes Association recommends limiting the amount of saturated fats and cholesterol in our diets. Saturated fats contribute to blood levels of bad LDL cholesterol. The amount of saturated fats should be limited to less than 10% of total caloric intake and the amount of dietary cholesterol should be limited to 300 mg/day.
Fructose: A type of sugar found in many fruits and vegetables and in honey. Fructose is used to sweeten some diet foods, but this type of sweetener is typically not recommended to diabetics because it could have a negative effect on blood sugar.
In type 2 diabetes, the body stops responding efficiently to insulin, a hormone that controls blood sugar. To compensate for the insensitivity to insulin, many diabetes drugs work by boosting insulin levels; for example, by injecting more insulin or by increasing the amount of insulin secreted from the pancreas. The new study, published in the June 9 issue of PLoS ONE, showed that a different approach could also be effective for treating diabetes — namely, blocking the breakdown of insulin, after it is secreted from the pancreas.
