Alpha-Linolenic Acid is a fatty acid and organic compound found in many common vegetable oils and is involved in the formation of prostaglandins. Related names: ALA; alpha Linolenic Acid; a-Linolenic acid; Flaxseed (Linum usitatissimum) Oil.

Could the Mediterranean diet protect the brain through the gut?

A narrative review finds that the Mediterranean diet may support brain health through gut microbiome, immune, metabolic, and barrier-related pathways, but direct human evidence that microbiome remodeling mediates neuroprotection remains limited. The proposed mechanisms involve microbial metabolites, reduced inflammatory signaling, stronger intestinal and blood-brain barrier function, and possible effects on processes linked to Alzheimer’s and Parkinson’s diseases.

Perilla oil may curb platelet reactivity and inflammatory signaling in smokers

An eight-week randomized trial found that daily perilla oil increased plasma and red-cell ALA, plasma EPA, and platelet closure time in healthy smokers. Perilla oil also reduced TNF-α and TBX21 gene expression, but it did not improve broader coagulation, lipid, endothelial, or postprandial markers.

Chia seeds may boost fetal brain DHA during obesity-linked pregnancy

Chia seed supplementation during pregnancy increased maternal omega-3 long-chain fatty acids, including DHA, in a rat model of high-fat-high-sugar diet-induced obesity. The findings suggest plant-derived ALA from chia seeds may improve maternal, placental, and mid-gestation fetal brain lipid profiles, but human relevance and offspring outcomes still need testing.

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.

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.

GLP-1 weight loss drugs leave users low on key nutrients, study finds

This study assessed nutrient intake in adults using GLP-1 receptor agonists (GLP-1RAs) and found widespread deficiencies in essential vitamins and minerals. Despite appetite suppression and weight loss benefits, most participants exceeded fat intake recommendations and failed to meet protein and micronutrient needs.
