This feels like we may be getting close to a solution for type 2 diabetes. That is the monkey stalking all of us who live a modern life. Old Age is not pleasant if you are fighting this.
I personally know several diabetes victims and it is difficult to share actionable advice that helps a lot. Yet by the time you have a problem that it identifiable, you are already suffering severe damage to your circulatory system that sends you down the road to ruin.
I have found though that the best actionable dietary step is to fold cabbage soup into your daily regime as a staple. One friend reports that he is taking up four bowls per day and his diet is generally improving as well. To that i have added canned Jerusalem artichokes as well. He is encouraged because his energy levels have risen.
At least he acted.
