Ann Fonfa's Correspondence with Dr. Lund

Dear Dr. Lund,

Congratulations on putting together a very interesting study. We support your goal to look at combinations of natural substances (and lifestyles) to reduce risk for cancer and other diseases.

We know that wild salmon contains much more n-3 than farmed fish. How will your study handle that issue?

May we receive information about your protocol? How are you recruiting? We maintain a website for people with cancer who are interested in complementary/alternative/natural approaches, which currently receives about two million visitors each year.

Dr. Lund responds:

Dear Ann,

All our fish is farmed and we have the n-3 content of it analysed. We have no evidence that farmed salmon has less n-3. In fact quite the contrary. In Europe farmed salmon are fed on fish meal based on oil-rich fish. This improves the health of the fish. Here are some results from a student project done in my lab last summer. You will not recognize the names of the supermarkets but I can tell you that Waitrose is up-market and tries to be ethical. Morrisons is bottom of the socio-economic scale but specialises in fish. Morrison’s and Tesco’s tend not to label the source of their food while Sainsbury’s and Waitrose do. The Nutreco fish is that which is being used in the study and is produced in Norway. The higher n-3 content usually reflects a higher total fat content rather than any difference in the types of fatty acids present.

You should also note that the Alaskan salmon we measured had much lower n-3 content – but this is a different species. It is very expensive in Europe.

A talk I gave recently is available on the ifr website if you would like to view it.

We are recruiting people who are being screened for polyps by the local gastroenterology unit. They cannot have a recognized genetic cause of disease and must not be taking fish oil capsules / cod liver oil etc. We assess dietary intake before and during the study using 7d food diaries and food frequency questionnaires.

We have a specialised FFQ for seafood as most are inadequate.

If I can help you further I will. When I find time I want to set up a webpage to explain more about the study to the wider world but time is always a problem!
