Researchers calculated U.S. consumption patterns from 1909 to 1999 by following the availability of essential fatty acids in 373 food commodities over the course of that time.
Diets high in omega-6s and low in omega-3s have been linked to a variety of problems relating to inflammation. A recent study conducted at the NIH National Institute on Alcohol Abuse and Alcoholism, published by the American Journal of Clinical Nutrition, attempts to elucidate the United States shift towards a diet overwhelmingly high in omega-6s.
Researchers calculated U.S. consumption patterns from 1909 to 1999 by following the availability of essential fatty acids in 373 food commodities over the course of that time.
Consumption of soybean oil, which is high in omega-6s, is estimated to have increased 1,000-fold during the time frame.
Overall availability of omega-6 linoleic acid (LA) increased from 2.79% to 7.21% of energy in the diet while availability of omega-3 alpha-linolenic acid (ALA) increased from 0.39% to just 0.72%. LA to ALA ratios increased from 6.4 in 1909 to 10.0 in 1999.
The researchers concluded that significant increases in omega-6 foods, primarily from soybean oil, have likely resulted in significant decreases in tissue omega-3 levels.
Recent animal study finds that Lysoveta may help reduce neonatal brain injury
July 17th 2024A recent animal study found that lysophosphatidylcholine (LPC)-bound omega-3 long-chain polyunsaturated fatty acids (LCPUFAs), marketed as Lysoveta by Aker BioMarine, protected against neonatal hypoxic-ischemic (HI) brain injury in mice.
Krill oil supplementation raises Omega-3 Index of Lupus patients in recent study
July 16th 2024The study was conducted at 20 research centers in the United States by Aker BioMarine and the Lupus Clinical Investigators Network with oversight by Lupus Therapeutics, the clinical research affiliate of the Lupus Research Alliance.
Meta-analysis does not find increased risk of bleeding events from omega-3 PUFA consumption
July 8th 2024Researchers reviewed 11 studies and found that there was no difference in the incidence of bleeding events between patients receiving omega-3 PUFAs and those not receiving them. High dose EPA consumption was associated with an elevated but modest risk.
Recent review states that pentadecanoic acid may support cellular stability for better longevity
June 25th 2024According to the paper’s author, Stephanie Venn-Watson, DVM, MPH, deficiency in pentadecanoic acid of ≤0.2% total circulating fatty acids increases the risk of ferroptosis, which a type of cell death cause by the peroxidation of fragile fatty acids in cell membranes that combines with iron thus increasing reactive oxygen species, and disabling mitochondria.
