if it is lower that is good, ideally below 120 before meals, if it is in the 90s, or slightly higher that is really good.

This is a great question to ask your doctor to find out both your goal blood sugar before meals, plus a goal blood sugar for 1-2 hours after eating. There are often variations in these targets based on overall health and diabetes treatment plan, so make sure to talk with your doctor to get your goal numbers. ~Lynn @Glucerna

It's not so much where it should be before a meal as it is that you don't want it to rise more than 40 points after a meal. Obviously, the lower it is to start the better it will be. Ideally between 70-120 before a meal is best. If you are higher, then you may want to make sure you take in less carbs or curb your portions.

Where is the proof to these readings? Maybe you are right, it's just mind boggling

Well according to the Mayo clinic the pre meal Blood Glucose should generally be ~ For many people who have diabetes, target levels are:
Before meals — between 70 and 130 milligrams per deciliter (mg/dL), or 4 and 7 millimoles per liter (mmol/L)
One to two hours after meals — lower than 180 mg/dL (10 mmol/L)
Fasting at least eight hours — between 90 and 130 mg/dL (5 and 7 mmol/L) (entire article ~

Thanks Jaybee...I know it as a general rule, but didn't have a source. You are the research guru here for sure.

are you sure we aren't supposed to surpass 40+ after a meal? Once I surpassed by 140

It is ideal if you don't. That is how you know your body doesn't like some foods and those that cause really high spikes you may want to avoid or adjust your amount that you eat. That is what people call a spike. That is what is ideal...but as we all know, ideal is not always reality.
