For drivers, the Blind Spot is the most dangerous unknown. For Americans and others that consume the Western Diet, Oxidative Stress is the Blind Spot for Health Care. Oxidative Stress is thought to be the cause of multiple health problems with many remaining asymptomatic for years. The list of diseases attributed to Oxidative Stress include heart disease, type 2 diabetes, and more. If you ask Americans about their health state and compare it to their actual health state, then you will see their Blind Spot, too.
Mirror, Mirror on the Wall, Who is the Healthiest of Them All?
The figure below compares the results of a 2015 Self Survey of Adult Americans for Health State and BMI. In the third column, the corresponding Diabetic State or Blood Oxidative Stress (BLOS) level are shown. About 1/3 of Adult Americans report Excellent Health with BMI and BLOS (most likely) in agreement. About 10% are honest about their Poor (and Fair) Health with Type 2 Diabetes being difficult to ignore. Here is the Blind Spot: About 60% of Adult Americans think they are in Good or Very Good Health, but BMI and corresponding BLOS level tell a different story. Why?
BLOS is a Long-Term Health Problem
Being Overweight or Obese is the primary target of public health professionals, but it should be a secondary target. Extra weight does not cause health problems beyond leg and joint problems. The evidence that fat causes chronic health problems is scant. Elevated BMI is only a Risk Factor. However, oxidative stress is thought to cause several health problems, due to reactive oxygen species (ROS). Continuous production of ROS by BLOS impacts tissue throughout your body. Long-term, elevated Blood Oxidative Stress or BLOS should be the primary target, since it is an asymptomatic disease. Reduction and management of BLOS may prevent the development of multiple health problems.
