Al does make a very good point. The human state has plenty of things to "worry" about and common sense things do get more than their fair share of the limelite. Except for allergies, the key to food is moderation. The original post mentions salt, fat, artificial ingredients as detrimental. None of these things in small doses is going to hurt anything. Maybe we need to qualify how MUCH we need to ingest before problems start? One whole bag of potato chips with cream cheese dip really reduces my performance. But a medium sized salad with strips of steak(salt and fat) or a Coke (artificial and sugar) doesn't. Let's keep the responses in line with each posters intention. Pigging out is pretty dumb before a major gig, but a glass of wine before a Brandenburg Concerto#2 has been all the dope that I have ever needed.
