Besides a supporting level of glucose is lower on 7.8 mmol /l in two hours after meal, try to avoid a rising glucose is more ,than on 2.5 mmol /l

  is on any time after meal, and if your   want  will  be  a most ambitious , not allow rising level is more ,than on 1.7 mmol/l is higher of glucose level on an empty stomach/if diabetes not diagnosed in you. That allow for you to individually regulate glucose level.

For example, if glucose in blood on an empty stomach has 5.0 , thus on ideal maximal rising  glucose after meal is not rise on 6.7 mmol/l/maximum is on 7.5 mml/l, if glucose of blood on an empty stomach has 4.5 mmol/l , thus maximal ideal stats on any time after meal is not rises on 6.2 mmol/l.

But if you want to be more healthy, thus for you is new goal:level of sugar in blood need to be better ,than ideal.Here , in this case, a level of glucose in blood is not to rise to 6.1 mmol/l on any time after meal eating. Thus, these stats has been received in a healthy absolutely in metabolic relation of peoples.

Thus remember, your optimal goals:  level of glucose in blood on an empty stomach is must to show 3.9-4.9 mmol/l, and after food on any time of moment is not higher on 6.1 mmol/l. Chance  by measured ,as not depending on  from that you are eaten or not , level of glucose is 11.1 mmol/l  or higher  or level of glucose on an empty stomach  is 7 mmol/l, or higher on both or more cases indicates on ,that you are probably has diabetes.

And by data table it indirects, that level of glucose is less on 6.1 mmol/l, is must  be a such,  if his to measure in 2 hours after meal, but if you want to check it, thus on a day one ,measure glucose,as after lunch or dinner on every 20 min  and by critically receive in attention any rise  a higher on 6.1 mmol/l, and not just a that, that will be in 2 hours.

A levels of glucose in blood in norm and pathology: 

 Optimally:Glucose is on an empty stomach -<4.9 mmol/l.

Glucose in 2 hours after meal: <6.1 mmol/l.

 Normally is glucose on an empty stomach:<5.6 mmol/.

In 2 hours after meal glucose:3.8-7.7 mmol/l.

 Prediabetes , glucose is on an empty stomach:5.6-6.9 mmol/l.

Glucose in 2 hours after meal :7.8-11.1 mmol/l.

 Diabetes, as glucose on an empty stomach:>_ 7.0 mmol/l.

 Glucose in 2 hours after meal: >_11.1 mmol.
