Dr. Lawrence gives a beautifully enlightening interview on the subject of her scientific research concerning the damages to the immune system that are caused by dioxin exposure. Dioxin exposed mice were found to be very susceptible to influenza infection. Science has not yet determined a safe level for dioxin exposure with regard to immune system damages. In precaution it would be very reasonable to reduce your animal fat consumption during the flu season to minimize the imposition of any dioxin exposure immune system deficits.
