The number of grams of staple food that can be eaten at each meal for abnormal glucose tolerance is not fixed, but generally ranges from 50-80 grams for breakfast and 100-160 grams for lunch and dinner, which need to be calculated according to height, activity level, and so on. Generally speaking, staple food should account for 50% to 60% of the total calories of daily food. For adults with abnormal glucose tolerance of medium stature, the daily intake of staple food is recommended to be between 250 grams and 400 grams. Of course, if one is obese, it can be reduced to between 200 and 250 grams. It is recommended to eat 1/5 of these staple foods for breakfast and 2/5 for lunch and dinner, i.e., 50-80 grams of staple foods for breakfast and 100-160 grams of staple foods for lunch and dinner. For people with abnormal glucose tolerance who are tall, engaged in heavy physical labor or higher-intensity physical exercise activities, the amount of staple food they need to eat at each meal can be more so as to satisfy the body’s needs. If the person is short, basically inactive, or engaged in lighter physical activities, the amount of staple food per meal can be reduced. It is important to note that skipping staple foods is not conducive to good health. Staple foods are the main source of energy for the body and are the material basis for life’s activities. People with abnormal glucose tolerance need to adjust their dietary structure under the guidance of a doctor, and should not resort to dieting and other ways to make adjustments without authorization, so as not to affect their health.
