My typical daily diet consists of the following:
Breakfast - Porridge, unsalted and unsweetened
Lunch - Home made bread (so I can control salt and sugar portions), meat and salad, Tortilla crisps and fruit like green banana and apple.
Dinner - Meat, mixed veg, 3 small potatoes (sometimes no potatoes)
Supper - May have some dark chocolate or a small treat.
Booze - Guinness (depending if im out) or a bottle of wine at weekends.
I cannot help thinking that you are focussing too much on sugar and salt and not enough on total carbohydrate. After years of preaching low salt they have now discovered that salt doesn't substantially affect BP at all and that too little salt is bad for you. I certainly would find that bread, fruit and
tortilla chips in one meal would be far too much carb for me and I am able to supposedly match carbs with insulin.
It sounds like your nurse is one of the old fashioned type who hasn't yet caught up with newer guidelines.
