In my book, The Plan, I discussed the studies which indicated that up to 90% of all fish oils on the shelves were in some state of rancidity. It’s well known that rancid oils produce free radicals which causes inflammation. Chronic low grade inflammation is the cause of premature weight gain, disease and weight gain. I also discuss in The Plan Cookbook, about the fragility of omega 3 and how when it’s exposed to high heat, it too will cause inflammation.
This is why cooked salmon can be 85% reactive, where salmon sashimi is roughly 10% reactive. New research shows how devastating the effects of ingesting rancid fish oil may be.
“Nearly 30 percent of newborn pups born to pregnant rats fed highly oxidized fish oil died within two days after birth a new study by researchers at the Liggins Institute at the University of Auckland in New Zealand finds. Mothers given this fish oil also had a higher incidence of insulin resistance at weaning compared with those given unoxidized supplements or water. The research is published in the American Journal of Physiology — Regulatory, Integrative and Comparative Physiology.
According to a summary of the research, “Omega-3 fatty acids are known to be chemically fragile or ‘unstable,’ and can easily break down when exposed to natural conditions such as light, heat and oxygen.” In a previous study, the research team found 83 percent of fish oil supplements sold in New Zealand to be oxidized beyond internationally recommended levels. This is in line with other studies that have found highly oxidated fish oil supplements in North America, South Africa and Europe.
“Once we discovered so many supplements were oxidized, we decided to focus on the health effects of oxidized fish oil during and after pregnancy,” research fellow Dr. Ben Albert, from the Liggins Institute at the University of Auckland said in the release. “We were surprised by the death rate,” said study lead Professor Wayne Cutfield, also from the Liggins Institute. “We’d expected some negative health effects on the rat offspring, but we didn’t expect them to die.”
