I see all these admonitions about eating 'healthy' in order to have a long life. This seems to be another example of quantity over quality. Within reason, why not enjoy this one-time trip we have called life. No one gets out alive, and it should be a great trip, not one where you worry about another tomorrow at the expense of a great today.
My Grandmother, born in 1886 on a farm in NC, never ate anything in her life that was low-calorie, low-fat, low-cholesterol, low-salt, low-sugar, or any other 'low' you can think up. She lived to be 97, with no sick days that I can remember. She didn't smoke and she fried the majority of what she ate. Her sister, born one year late, ate anything she wanted and smoked until she was 90, and lived to 98.
The conclusion I am suggesting, is that worrying about what you eat and its effects on your later life, is more stressful to your body than eating what you want and like and enjoying your life. Worry and its stress will kill you quicker than any food you can name. SO, don't worry, be happy!
