Suppression by diets rich in fish oil of very low density lipoprotein production in man.
P J Nestel, W E Connor, M F Reardon, S Connor, S Wong, and R Boston
Comment: One study I encountered showed an increase of 2.5% over a one year period. Many believe the affect on LDL is inconclusive. However, we should recall that while LDL is one marker, a more significant one in triglyceride level, which has been consistantly shown to be reduced by fish oil.
Claim #2: Decreases immune function
Counter: Modulation of postoperative immune response by enteral nutrition with a diet enriched with arginine, RNA, and omega-3 fatty acids in patients with upper gastrointestinal cancer.

Comments: This claim holds no water when looking to the available research.
Claim #3: Toxic Vitamin A and D
Evidence of a role for retinoic acid (vitamin A-acid) in the maintenance of testosterone production in male rats.
Role of Vitamin D in Skeletal Muscle Function*

Benefits and requirements of vitamin D for optimal health: a review
WB Grant, MF Holick
Comments: While only applying to Cod liver oil, this claim is so false it drove me half mad. Vitamin A and D CAN be toxic, but it takes more than some cod liver oil to do it. While staying under toxic doses, they have a myriad of benefits, including ones directly applying to bodybuilding/ weightlifting (see the top of my counter).
So, are you happy? Is this enough to counter your un-cited excerpt of a book? I hope this clears fish oil from these unfounded allegations.
