I never paid much attention to my blood sugar (aka blood glucose, or as I will simply refer to it, glucose) until a few years back, when I started getting more interested in self-tracking/biohacking and my 23andMe DNA analysis showed that I had a genetically elevated risk for type 2 diabetes, which has been shown to be preventable by maintaining low levels of glucose. Elevated glucose can also contribute to a number of other health issues such as cardiovascular disease.
The current “accepted” recommendations by the American Diabetes Association for fasting glucose (i.e., no food or drink in the previous 8 hours) are between 70 – 130(!) mg/dL. The exclamation(!) mark is there for a reason. The upper bound is being hotly disputed – in fact, the ADA has a term called “impaired fasting glucose” that was lowered from 110mg/dL to 100mg/dL in 2003. That means that many people that are classified as “normal” are, in fact, pre-diabetic. Organizations like the Life Extension Foundation (a leading organization focused on advancing research on longevity and anti-aging) suggest keeping fasting glucose at or below 85 mg/dL (and optimally even below 80!).
My most recent blood test showed my fasting glucose level was 85mg/dL, considered “good”, even by Life Extension Foundation guidelines. But what I wanted was to better understand how various factors affected my levels, and then be able to proactively control them. Even though my glucose is considered good, I wanted it to be optimal. Why take any chances? [Read more…]
