Your two points are NOT mutually exclusive. I totally agree that a good diet absolutely trumps the supplements. (Incidentally, you didn't mention exercise, another crucial factor).
We know FOR SURE that a low fat, heart healthy diet is good for general overall health and to help retard PC. Ditto for exercise.
I have to admit that my diet is pretty good, but it could be better. I still like/enjoy the occassional steak and pizza and even cake/ice cream. I should eat more fresh fruits and vegetables. I also need to get more exercise. I've had some physical issues that have interfered with my gym activities. But, hopefully I will soon be back to my vigorous workout routine.
David, it is really difficult to respond to you because you take offense so easily. But, let me try. Saying that Casey's use of caps and bold print doesn't add credence to his points is correct. But it doesn't diminish his points either.
Constantly saying that your dieticians do not advocate supplements does not make your point true either. Little by little there does seem to be a gathering of evidence that points to certain supplements as being beneficial. I will lean more towards the top experts such as Strum, Myers, Scholz, Lam, etc. that are recommending
Just as diet trumps supplements (except that as I said they are not mutually exclusive), I have to say that the advice of the experts for me trumps your dieticians.
By the way, Gibson, I don't think the supplements in the dosages recommended will hurt -- they have not been shown to hurt.
Having said all that, let me add that I still have a degree of skepticism about the supplement issue. Companies have sold people a bill of goods on worthless supplements, especially in the light of eating a good diet. For example, if one eats well, then multivitamin supplements are a waste. Additionally, we do seem to have studies that praise a supplement and then a study comes out that shows it's worthless. A good example is beta sisterol for benign prostate problems. Incidentally, as an aside, one supplement that does seem to help me is a glucosamine/msm combination tablet (no chondroitin). It helps with a knee issue. In fact it has helped about 100%!
Anyway, the one attraction that allows these companies to make a fortune is that it is so easy to take a pill. Hey, why exercise to lose weight. Why eat sensibly? I can take this fat burning tablet and...oh, yeah, I got to go buy this bridge.
So, in conclusion, supplements and their marketeers have earned a bad name. But don't throw the baby out with the bath water. As Casey points out, there is a growing mountain of evidence that gives a favorable nod to some supplements in the fight against PC. I'll take the pills, remain skeptical, and hope that the experts are right.
