I think I understand your dilemma Ira, I have had several husbands share this concern with me. Ultimately it comes down to dialogue with your spouse. You need to express your concerns about your health and let her express her concerns about how she has learned to cook for you.
Don’t blame just share. For example,
Honey I am concerned about my health and I have been reading that deep fried foods can lead to being overweight, and various diseases. I was wondering if there was something we could do to make a change in the foods we have chosen to eat?
Avoiding the talk is an injustice to both of you.
