DHA: Boost Your Brain

Posted on May 18, 2014 by Robert Barrington

Docosahexaenoic acid (DHA, C22:6 (n-3)) is a long chain polyunsaturated fatty acid found in cold water fatty fish such as trout, tuna, mackerel, salmon and sardines. These fish bioaccumulate DHA from marine algae that are able to synthesise the fatty … Continue reading →

Hydrogenated, trans and Deodorised Fats

Posted on October 30, 2013 by Robert Barrington

Polyunsaturated fatty acids (PUFA) from plants have important health implications because two of these fatty acids, α-linolenic acid (ALA, C18:3 (n-3)) and linoleic acid (LA, C18:2 (n-6)) are essential to health. Unsaturated fatty acids have double bonds that gives the … Continue reading →

Cyclooxygenase Inhibitors: The Sword of Damocles

Posted on October 21, 2013 by Robert Barrington

yclooxygenase (COX) inhibitors are a sub-group of the non-steroidal anti-inflammatory drugs. These drugs, that include common over the counter medicines such as aspirin and ibuprofen, inhibit the cyclooxygenase enzymes non-selectively. Cyclooxygenases are a group of enzymes required for eicosanoid (prostanoid) … Continue reading →

Fish Oil: Responders and Non-Responders

Posted on August 13, 2013 by Robert Barrington

vidence suggests that some of the inconclusive results in nutritional intervention studies may be due to the presence of non-responders within the study population. For example, calcium is able to lower blood pressure in some individuals with hypertension, but a … Continue reading →

Does Vitamin E Decrease Platelet Aggregation?

Posted on July 20, 2013 by Robert Barrington

Detrimental changes to platelet aggregation can be caused by an imbalance in dietary intake of the essential fatty acids. This is because both α-linolenic acid (ALA, C18:3 (n-3)) and linoleic acid (LA, C18:2 (n-6)) are converted to other fatty acids … Continue reading →

So Long, and Thanks for All the Fish

Posted on May 7, 2013 by Robert Barrington

pidemiological studies suggest that consuming fish is associated with a decreased risk of cardiovascular disease. Fish may be protective of cardiovascular disease because of the long-chain fatty acids contained within it. Fish oil accumulates in the skin of some species … Continue reading →

Farmed Versus Wild Fish: Omega 3 to 6 Ratio Differences

Posted on April 18, 2013 by Robert Barrington

The long-chain fatty acids eicosapentanoic acid (EPA, C20:5 (n-3)) and docosahexanoic acid (DHA, C22:6 (n-3)) have been shown to be beneficial to human health. The benefits of EPA and DHA derive from their physiological role in the synthesis of cell … Continue reading →

Essential Fatty Acids: The Ratio is the Key

Posted on March 27, 2013 by Robert Barrington

The fatty acids α-linolenic acid (ALA, C18:3 (n-3)) and linoleic acid (LA, C18:2 (n-6)) are essential in animals including humans, and therefore required in the diet. Deficiency of either fatty acid causes disease and death. Both fatty acids are converted … Continue reading →
