Type 2 diabetes has a genetic component and a very large lifestyle component. Type 2 diabetes can be reversible with the following measures (I have seen this happen with many people)
1) Low carb diet (ketogenic approach if diabetes is severe, low carb / paleo style if not so severe), avoiding all added sugars, limiting or eliminating sweet fruits and starchy vegetables.
2) Weight loss to optimal level (keto / low carb helps greatly with this).
3) Exercise - regular.
4) Stress management
Just eat proper diet eat plenty of fruits and vegetables and i hope it help turmeric is known miracle spice and have health benefits in our body
Besides everything mentioned above, checking HbA1c once a year is very useful in monitoring for prevention :)
