Many people (including myself) have noticed a reduction in the number of colds they catch now that they're eating paleo. Vitamin D levels seem like a big player in this, but so does one's level of systemic inflammation.
Melissa has suggested that (in her experience) fish oil is not only anti-inflammatory, but immunosuppressive as well. However, in her book Ah-Choo! Jennifer Ackerman argues that having a compromised immune system actually helps reduce cold symptoms. In other words, it's your body's overactive immune response to a cold virus that causes the problem, not the virus itself.
I have yet to try mega-dosing on fish oil as treatment for a cold, but I have tried fasting. Subjectively, the fasting does seem to help, and (at least in theory) would have the same anti-inflammatory/immunosupressive effect as high dose fish oil.
So basically, I'm confused. Do I want to decrease my inflammatory/immune response to reduce cold symptoms, or do I want to increase my inflammatory/immune response to fight it off?
And how does Vitamin D fit into this? By boosting your immune system or as an anti-inflammatory?

I don't think you can really distinguish between antiinflamatory and immunosuppressive. Both mean a dampening down of the immune response. In the first, there may be an assumption that the body is already overresponsive and so the dampening would be a good thing, while in the second, there may be an assumption that the dampening down has gone too far and so the dampening may be a bad thing, but in both cases, the same general thing is happening.
Ideally, the body would pick the exact right level of response. But why does it not? Could it be too stupid to know? Or maybe the body actually has a somewhat logical reasonf or doing what it is doing. Maybe it is that when the body is weak and out of balance, it also tends to be hypervigilant for signs of attack. A weak animal is a nervous and wary animal and a strong animal is a relaxed one. A weak animal might jump and run at the slightest sign of strangeness, simply because it knows it can be easily overwelmed if it doesn't get a head start and react immediately. Whereas, you see the lazy lion snoozing in the middle of the savanna. He is not going to get up and get all excited by a mere twig snap caused by a bird. He will only move if he clearly sees the danger. He needn't worry much because he knows he can easily handle most things that come his way. Of course, he will not lay there and let a herd of deer kick him in the head. So he will move, but only when appropriate and for good reason. YOu could say the lion is like a healthy immune system. It is strong and knows when to move and when to relax.
Maybe looking for things that are 'antiinflammatory' is not really that much different than looking for things that improve our health in general.

Cold symptoms aren't the result of an over-active immune system -- they're a consequence of the immune system taking care of business and defeating the virus. For example, a runny nose is the body expelling the virus & immune cell leftovers. Coughing is the body expelling matter from the lungs. And so on.
Allergies, on the other hand, are an over-active immune system of sorts -- the immune system attacks harmless particles such as pollen, and the result is the same symptoms as when you have a cold.
Vitamin D is starting to be known as essential for the immune system, hence less illness.

The NYT health section is quite anti-supplement and, well, really anti anything other than pharmaceuticals.... That said, I think if you ignore some of what is written, the author answers your question. And, the answer is the exact opposite of the answer Kilton gave you... :)
