IIN my husband gets upset after seeing me eat something unhealthy

YES, he's controlling and you need to put him in his place. Many octogenarians and people even older have eaten fried foods and other things the health nuts consider "unhealthy" all their lives. With all the additives, preservatives and pesticides in food today, it's doubtful one food is any more, or less, healthy than another. If you consumed saturated fats every single day at every meal, possibly, you could develop arteriosclerosis that could lead to other problems, but ordering fried foods when you go out isn't going to hurt you.

BTW, is your husband also an exercise freak? If so, remind him that exercise also takes its toll on the body because excessive exercise produces what are known as free radicals, i.e., “angry” oxygen atoms that are missing an electron. These angry atoms float through the body, wreaking havoc as they attempt to “steal” electrons from other cells. As this occurs, the cells in the body are damaged, which also damages the cardiovascular system. This is the reason runners and other exercise freaks often die relatively young.

In the end, how long a person lives depends more on genetics than anything else.
