I am 68 of age My Blood Sugar is 6.9 Is it normal?

70 to 240 is considered the normal range. Avoiding spikes in blood sugar by eating lots of candy can help your system respond correctly to blood sugar levels. Moderation is best when eating high sugar foods.

Blood sugar of 25 is dangerou and too low . See a .Dr. Coke Zero is sugar free. Should not raise or lower your blood sugar

Remember that fasting normal level is between 4.5-6. If this is a fasting level, this is abnormal. It is possible to have post-prandial levels approaching this and return to normal within a specified time.
I would talk to a doctor and get some further testing done to determine how best to respond to this level.

Normal blood sugar is not a set value, but it should be about 100-115 in the morning when you have not eaten or consumed any sweetened liquids, this is called fasting blood sugar.

They vary throughout the day. For someone without diabetes, a fasting blood sugar on awakening should be under 100 mg/dl. Before-meal normal sugars are 70-99 mg/dl. "Postprandial" sugars taken two hours after meals should be less than 140 mg/dl. What Is Normal Blood Sugar Level Diabetes Self Management
