There is sufficient evidence to indicate that a diet consisting of
foods high in natural antioxidants such as raw fruits and vegetables provide anti-inflammatory benefits. The higher the intake the more they are associated with
significant reductions in levels of markers of inflammation, including C-reactive protein (CRP), interleukin-6 (IL-6) and tumour necrosis factor-alpha (TNF-alpha).
This just shows how a little bit of knowledge can be a dangerous thing. Inflammation isn't something you want to inhibit...just because it's associated with illness. Inflammation is one of the primary mechanisms involved in immune responses. If this article is to be believed whole heartedly, we should not be trying to inhibit our immune responses.
And why a little bit of knowledge is a dangerous thing, illness is not simple. It is a complex interaction involving our body, our environment, and the etiologic agent. Anti-oxidants have their role, but they are no panacea. Your body produces it's own for one. For another, the problem with cancer isn't your bodies production of proteins like TNF-alpha or interleukin-6, the problem is the cancer cells themselves bypass our bodies controls. Depressing proteins like those I just mentioned in a healthy person is sure to cause problems, and in cancerous tissue the cancer itself is already bypassing the effective homeostasis.
Gah! If it were that easy...well there would be less cancer. It's not that easy.
