Thank God you have pointed out the difference between T1 & T2 was reading through and was going to post myself till I saw this from you Nemesis! My daughter is T1 has been for 6yrs now and it really annoys me when people just hear diabetes and think "diet will save you" "don't eat suger/carbs" not thinking what type of diabetes have they got, sugar/carbs can and does save T1's life's!
Type 1 diabetes is not something you get from eating wrong it's an autoimmune condition and there is nothing you can do apart from take your insulin as your DSN tells/shows you and eat a healthy balanced diet.
It's true that T1 isn't something you get from improper eating habits. But TBH your advise is sound advice for both T1 & T2:
1) eat a balanced diet as directed by your dietician (the visit with the dietician should have been referred by your diagnosing physician)
2) take your meds as directed by the diagnosing physician and diabetic education nurse
3) keep carbs or a sugary food (or drink) or glucose tablets handy in case your sugar bottoms out.
In addition to these you can expect:
1) regular follow-up checks (usually every three months) with either the physician or the diabetic education nurse
2) referrals and regular follow-up checks with specialists (optometrist & podiatrist) at least annually and pay close attention to your feet daily
3) Pay more attention to dental hygiene and expect more frequent dental exams/cleanings
