I agree with Mongoose.
Either you're ready, and committed to make a drastic change, or you're not.
OP's husband isn't. And whether he should or not is also a good question.
A few changes to get the bs down to a reasonable level is a good enough start.
As a heart bypass patient on that cocktail of drugs maybe a diet heavy is salty processed high fat foods isn't a good alternative either.
One size doesn't fit all.
Organic is good, so clearly the op is trying to eat healthy herself. Eating the same would be easier to cope with.
But the big question.
So how do you get someone who hasn't cared for twelve years to change?
Madbazzo I think has the right approach.
"My advice would be to eliminate all sweets, cakes, biscuits, sugary drinks including most fruit juices, white bread, potatoes in most forms, vegetables grown below ground, white rice, pasta, pizza, pies and fried foods. Also anything using refined white flour. Watch out for all breakfast cereals which can be high in both carbs and sugar. If buying supermarket packaged, tinned or frozen foods look for the traffic light symbols and avoid most things with red lights.
Substitute wholegrain seeded bread, brown rice, wholemeal pasta, green vegetables (or grown above ground as less starch). Increase your proteins such as lean meats, chicken, fish, eggs etc"
