Are fats evil?

Not wanting to get into a low carb debate, but would just like to get your opinions on a talk I had at university today. I study environmental science, although I specialise in micro, I'm trying to get more into the chemical aspects which will help with jobs etc. The talk was by a professor who works for marine scotland on pollutants in the environment and how they end up in organisms (foucusing mainly on marine flora and fauna). As we had talked about lots of different carcinogens and endocrine disrupters a question was asked from the audience and I was intrigued to find the answer.
It was do people with endocrine conditions have their samples analysed at the hospital to search for traces of these dangerous pollutants. The simple answer was no mainly because they understand so much about animals because they are able to collect and analyse dead bodies, and also to collect and disect other specimens. They had discovered that dog whelks in Aberdeen harbour had both male and female sex organs beacuse of a chemical used to stop growth of organisms on ships hulls. The chemical was later banned and the dog whelk population is now back to normal.

My main point was that the prof then started on a bit of a personal rant about fats. He himself trys wherever possible not to eat any and also limits the amount of meat fish dairy etc. His reason is that the pollutants that are most toxic and hang around causing more damage in an organism are hydrophobic (they don't like water) so therefore when introduced to tissues they accumulate in fats. These chemicals then bioaccumulate up the food chain, causing cancer, endocrine conditions etc. This is why he aviods fats at all costs.
What are your thoughts on this?

Poor professor, he doesn't seem to realise what really does make you sick is high blood sugar. Cancer cells for instance loves glucose. And highish bg, even below the diabetes limit, raises the risk for dementia a lot.

He does have a point in all the chemicals in the environment. One way to minimise this is to go for organic food. Another is to join Greenpeace or such.

Unfortunately no way to avaoid them, even if you eat organic, they will still accumulate over the years. It did make me wonder though, when the girl suggested people be tested he completed agreed and said we should, but we aren't. The hospital has some of my liver that could easily be tested I would love to see how many pollutants I had picked up over the years. And then wether or not there would be any link between endocrine conditions, cancer, enzyme defections and the level of pollutants. Nordic countries have the highest incidence of type 1 I believe but they also have some of the highest levels of pollutants due to climate and ocean cirulations. It all gets dumped nearer the poles apparently.
