Answer:
Order anything on the menu labeled "sugar-free" or "fat-free."
Explanation:
Ample research evidence supports the fact that reduction in sugar and fat diets is a relevant treatment for pre-diabetes. If the sugar and fat intake of the patient is reduced, the blood sugar levels may be lowered because more sugar is prevented from entering into the patient's blood stream. Reducing sugar intake can also help reverse insulin resistance.
Intake of a diet of sugar that digest quickly may lead to a spike in blood sugar level of a pre-diabetes patient, the body often find it difficult to lower blood sugar levels after such a meal. Hence, ordering anything on the menu labeled "sugar-free" or "fat-free" can help to minimize Diana's spikes in sugar level.
