Epidemiologic studies have shown a beneficial association between polyunsaturated fatty acid (PUFA), specifically linoleic acid (C18:2, n-6), intake and cardiovascular disease morbidity and mortality. Clinical studies have shown that n-6 PUFAs have the most potent cholesterol-lowering effects of the individual fatty acid classes, and emerging evidence suggests that PUFAs have favorable effects on postprandial lipemia. However, some studies suggest that high intakes of linoleic acid may have adverse effects on proinflammatory cytokines and adhesion molecules. Research is needed to establish the optimal level of dietary PUFAs that maximally affects the greatest number of health risk factors.

Mice born to mothers fed a diet high in omega-6 fatty acids and low in omega-3 fatty acids during pregnancy exhibit various behavioral changes including impaired social behaviors and enhanced recognition memory.

Department of Physiology and Oral Physiology, Graduate School of Biomedical and Health Sciences, Hiroshima University, Hiroshima 734-8553, Japan.
Background: Modern dietary trends have led to an increase in foods that are relatively high in n-6 polyunsaturated fatty acids (PUFAs) and low in n-3 PUFAs. We previously reported that the offspring of mother mice that consumed a diet high in n-6 linoleic acid (LA) and low in n-3 α-linolenic acid (ALA), hereinafter called the LA/ALA diet, exhibit behavioral abnormalities related to anxiety and feeding.
Objective: We currently lack a comprehensive overview of the behavioral abnormalities in these offspring, which was investigated in this study.
Association of Specific Dietary Fatty Acids with Asthma in Urban School Children and Adolescents: Inferences from a Cross-Sectional Multicentric Study From India.

School of Public Health, DY Patil Deemed to be University, Navi Mumbai, Maharashtra, India.
Objective: To assess the association of dietary fatty acids with asthma in Indian school children.
Methods: Children aged 6-16 years were enrolled from randomly selected urban schools in 10 cities. The International Study on Asthma and Allergies in Childhood Phase III Questionnaire was used to assess the prevalence of asthma.

Purpose Of Review: Berries are a great source of fiber, polyunsaturated fatty acids, and beneficial secondary metabolites (polyphenols). Various phytochemicals present in berries (glycosidic-linked flavonoids, anthocyanins, etc.) provide potential health benefits to consumers.

Background And Aims: Obesity is associated with a higher risk of severe diseases such as atherosclerotic cardiovascular disease, type 2 diabetes mellitus (T2DM), and metabolic dysfunction-associated steatotic liver disease (MASLD). Polyunsaturated fatty acids, of the omega-3 family (n-3 PUFA), have been shown to reduce adipose tissue inflammation in obesity, as well as to have lipid-lowering effects and improve insulin sensitivity. However, direct effects on liver transcriptome in humans have not been described.

Background: Brain accumulation of amyloid-ß (Aß) in plaques and neurons is the cause of AD neuropathology that is opposed by autologous monocyte/macrophages (MMs) in health but this defense fails in AD.
Method: RNAseq, immunochemistry of the brain, immunofluorescence, and confocal microscopy of macrophages.
Result: In the AD brain, MMs shuttle Aß from parenchyma to vessels, which develop vasculitis, causing amyloid-related imaging abnormalities (ARIAs).
