If you had a good friend with multiple health problems and yet she continues to eat the worst food imaginable, would you say something to her?

I have a good friend that I’ve known for about 15 years, and she has developed high blood pressure, high cholesterol and is on the verge of diabetes. Despite these health conditions, when I ask her what she did this weekend or holiday, she will say that she and her boyfriend cooked a ham, macaroni and cheese, etc. This is not occasionally, this is all the time. I am tempted to say something to her but I don’t because I don’t want to annoy her or make her feel like I am preaching. She’s not a stupid person and I know that everyone likes to eat “fun” food every now and then, but she does it all the time.

If you had a friend in this condition, and she were eating bad foods, would you say something to her or let it go?
