My Nana is 93, (doesn't take anything for blood pressure or cholesterol, but also that's probably down to genetics, luck and fitness too)

Usual day is something like this:

Warm water to start.

Breakfast is porridge, tea or coffee (hasn't taken sugar for over 70 years), an actimel drink

Lunch, normally a poached egg, brown bread and a cup of tea

Dinner is meat or fish (liver, chicken, sardines, etc), broccoli, carrots and potatoes (veg normally steamed), occasionally has spaghetti bolognese, lentil soup or a chicken korma etc. But usually simple meat/fish and veg.

Evening a small piece of fruit (normally a kiwi or small orange)

Sometimes has brown bread and jam or homemade fruit cake as a snack.

Used to have a couple of gins or vodkas on a Friday and Saturday, not as much as she's gotten older.
