There may be another area to look in the chart... look for a virus.
Studies point to viruses as cause of diabetes It may run in families because of carriers or maybe it is the DNA is sensitive to contract the virus.
Being Diabetic (I always blamed my stressed Jupiter with the sextile to Venus) I keep an eye out for info to start protecting my kids before they possibly develop it. Even if you are eating sugar, cut back on other carbs then, drink lots of water to dilute the sugars, heavily eat fiber, and finally be sure to include exercise daily, even if it is just walking. There is no way I am passing up on a Buttermilk Chess Pie
, so it needs to be fitted in with everything else, including medication and passing up bread that day.
