Arachidonic Acid News and Research

RSS

Arachidonic acid is an omega-6 fatty acid that is present in the phospholipids (especially phosphatidylethanolamine, phosphatidylcholine and phosphatidylinositides) of membranes of the body's cells, and is abundant in the brain. It is the counterpart to the saturated arachidic acid found in peanut oil.

Breast milk fats may reflect more than the fats a mother eats

A cross-sectional study of 109 breastfeeding women in the Netherlands found that maternal intakes of omega-3 and omega-6 PUFAs and trans fats were associated with corresponding fatty acid proportions in human milk. The researchers also identified links involving dietary fiber, diet quality and several micronutrients, although whether these relationships reflect direct biological effects or broader dietary patterns remains uncertain.

High-dose DHA reaches the brain but fails to protect memory

High-dose DHA effectively increased brain levels in older adults at Alzheimer's risk, but did not lead to cognitive or structural brain health improvements.

Gene linked to lower BMI points researchers toward a new obesity target

A review in Cardiology in Review highlights GPR75, a receptor for 20-HETE, as a promising therapeutic target for obesity and metabolic syndrome. Evidence from genetic studies, cell experiments, and mouse models suggests that blocking this pathway could influence weight gain, insulin resistance, hypertension, inflammation, and vascular dysfunction.

Stanford scientists map the molecular diversity of different global populations

Researchers at the Stanford School of Medicine have found that ethnicity and geography may influence human molecular makeup - from metabolism and immunity to gut microbiota and biological aging.

Natural compound obakulactone shows therapeutic potential for rheumatoid arthritis

A new study published in Engineering reveals that obakulactone (OL), a natural tetracyclic triterpenoid isolated from Phellodendri cortex, exerts a therapeutic effect on rheumatoid arthritis (RA) by promoting the degradation of acyl coenzyme A thioesterase 1 (ACOT1) via the ubiquitin‒proteasome pathway and restoring the homeostasis of unsaturated fatty acids.

Eating oranges daily may shift lipid patterns in fatty liver disease

A 4-week trial on 'Navelina' oranges shows potential effects on lipid metabolism in fatty liver disease, revealing intriguing but non-significant patterns.

When omega-3 may help mental health and when they may not

Investigating omega-3 fatty acids, this review highlights their impact on mental health, inflammation, and the potential for therapeutic use in disorders.

Plant-based omega-3s work better than expected in a year-long diet study

A year-long, diet-controlled intervention shows that flaxseed oil–derived alpha-linolenic acid significantly increases erythrocyte EPA, DPA, and DHA across omnivorous, vegetarian, and vegan diets. The magnitude of improvement is driven mainly by baseline omega-3 status, while absolute EPA and DHA levels in vegans remain lower than in omnivores.

Why soybean oil may fuel weight gain

Researchers investigate how soybean oil may disrupt fat metabolism to potentially increase the risk of obesity.

Changes in brain fats play a key role in Alzheimer's development and progression

More than a century ago, Alois Alzheimer noted unusual changes in brain fats, which he described as "lipoid granules," along with the buildup of amyloid-beta (amyloid) plaques and tau protein tangles.

Trial investigates how quickly human milk responds to common plant based meat swaps

Replacing beef with a plant based beef substitute for six days changed the fatty acid composition of human milk, increasing medium chain saturated fats and lowering key long chain polyunsaturated fats such as arachidonic acid. These biochemical shifts occurred without changes in maternal weight, appetite, glucose patterns or infant milk intake.

Novel approaches to understanding EETs and cardiovascular disease

Some products of arachidonic acid have already been well studied: the prostanoids formed by cyclooxygenases are central mediators of inflammation, fever, and pain.

Cannabidiol shows promise for obesity and metabolic syndrome

Cannabidiol (CBD) shows promise in regulating appetite, glucose and lipid metabolism, and inflammation in preclinical models of obesity and metabolic syndrome. However, human evidence is still limited, highlighting the need for rigorous trials before clinical use.

Fatty acids circulating in the blood predict bone mineral density from childhood to adolescence

A recent study by the University of Eastern Finland is the first to report that the fatty acid composition of blood and the enzyme activity associated with it predict the development of bone mineral density from childhood to adolescence.

Can honey protect your brain? Study reviews its potential against Alzheimer's

This review examined 27 preclinical studies on honey and Alzheimer’s disease, showing honey’s bioactive compounds counter oxidative stress, inflammation, and amyloid buildup. Despite promising lab results, no human trials exist, underscoring the need for clinical research.

Breast milk fatty acids help babies sleep longer, study finds

Researchers found that higher levels of polyunsaturated fatty acids (PUFAs) in human milk are associated with longer sleep duration in exclusively breastfed two-month-old infants. The strongest effects were observed for daytime (diurnal) sleep, especially with omega-3 and omega-6 fatty acids.

Study finds no link between omega 6 and increased inflammation

A new study published in Nutrients offers new insight into omega-6 and whether it is truly the proinflammatory fatty acid many claim it to be.
