Then how is it that my grandmother managed to live to 90 (and is still going) despite making biscuits and gravy every morning for 70 years now? Not to mention all the pies and cakes and loaves of bread she made over the years. As well, she breads just about every meat she cooks (fried). And all her kids are alive and well and well into their 60s.
Obviously there are extremes. I would never add sugar to things like chicken broth as that person you were talking about does. Nor do I add salt to my food. I haven't had a salt shaker in my house since I was a kid.
