On the other hand, one still encounters reports that demonstrate how ignorant many researchers are. Not only are they ignorant of things outside of their field of speciality, but they also appear to be ignorant of things they presumably should be familiar with:

One claim is: "Using an animal model, Chun-Lin Chen, a senior graduate student on Dr. Huang's research team, found that cholesterol limits the activity of a key protective protein called transforming growth factor-beta (TGF-beta)..."
First of all, are un-natural amounts of cholesterol being used? And secondly, is the choelsterol largely oxidized is it non-oxidized? Then there is:
"...the findings also suggest answers to questions about other diseases associated with high blood cholesterol levels, including cancer..."
There is a lot more evidence that low cholesterol leads to cancer, not "high cholesterol." And, more generally, the approach of these researchers is focused on molecules that are over-expressed or under-expressed. Once that is determined, they can try to make drugs to inhibit or enhance the production of these molecules, though long-term effects in humans won't be known for years. They usually fail to even consider that something not natural (such as a huge amount of free radical activity) might be causing the over or under-expression in the first place, and that prevention might be very simple. |
