Decreasing dietary linoleic acid promotes long chain omega-3 fatty acid incorporation into rat retina and modifies gene expression

2011

International audience; Age-related macular degeneration (AMD) may be partially prevented by dietary habits privileging the consumption of ω3 long chain polyunsaturated fatty acids (ω3s) while lowering linoleic acid (LA) intake. The present study aimed to document whether following these epidemiological guidelines would enrich the neurosensory retina and RPE with ω3s and modulate gene expression in the neurosensory retina. Rat progenitors and pups were fed with diets containing low or high LA, and low or high ω3s. After scotopic single flash and 8-Hz-Flicker electroretinography, rat pups were euthanized at adulthood. The fatty acid profile of the neurosensory retina, RPE, liver, adipose tis…

Serum omega-3 fatty acids are not associated with age-related macular degeneration

2012

Revue non indexée dans le JCR.; International audience; Evaluation of: Kabasawa S, Mori K, Horie-Inoue K et al. Associations of cigarette smoking but. not serum fatty acids with age-related macular degeneration in a Japanese population. Ophthalmology 118(6), 1082–1088 (2011). Age-related macular degeneration (AMD) is the leading cause of visual impairment in the elderly. in developed countries. Risk factors for AMD are classified into endogenous nonmodifiable. factors, including genetics and environmental factors such as smoking and dietary habits. Both. epidemiological and experimental studies suggest that dietary omega-3 long-chain fatty acids. would participate to prevent from the develo…

Future perspectives of the pharmacological management of diabetic dyslipidemia

2019

Introduction: Diabetic dyslipidemia is frequent among patients with type 2 diabetes mellitus (T2DM) and is characterized by an increase in triglycerides (TGs), low-density lipoprotein cholesterol (LDL-C), and small-dense (atherogenic) particles, and by a decrease in low high-density lipoprotein cholesterol (HDL-C) and apolipoprotein (Apo) A1 that are strongly related to insulin resistance. The increased flux of free fatty acids from adipose tissue to the liver aggravates hepatic insulin resistance and promotes all of aspects of the dyslipidemic state. Areas covered: Statins are the first-line agents for treatment while other lipid-lowering drugs (ezetimibe, fibrate and proprotein convertase…

Stabilization of a nutraceutical omega-3 fatty acid by encapsulation in ultrathin electrosprayed zein prolamine.

2010

Docosahexaenoic acid (DHA) is a long chain polyunsaturated fatty acid of the omega-3 series (omega-3), which exerts strong positive influences on human health. The target of this study was the stabilization by encapsulation of this bioactive ingredient in zein ultrathin capsules produced by electrospraying. The zein ultrathin DHA encapsulation was observed by ATR-FTIR spectroscopy to be more efficient against degradation under both ambient conditions and in a confined space (so-called headspace experiment). In the latter case, that more closely simulates a sealed food packaging situation, the bioactive DHA was considerably more stable. By fitting the degradation data to a specific auto-deco…

Food as medicine in psychiatric care: Which profession should be responsible for imparting knowledge and use of omega-3 fatty acids in psychiatry

2011

Accepted version of an article in Complementary Therapies in Clinical Practice, 17 (2011), 107-112. Also available from the publisher: http://dx.doi.org/10.1016/j.ctcp.2010.08.001 The effect of omega-3 fatty acids on depression is well documented. The purpose of this study was to determine if and how food is used as medicine in psychiatric care, especially how omega-3 fatty acids are used as a supplement in the treatment of depression. This is a pilot study with a qualitative design using questionnaires and interviews among nursing students, tutor nurses and psychiatrists. Three main categories emerged: 1. Nutrition is considered important but few evaluations are made. 2. There was a lack o…

Latvijas aptiekās pieejamo zivju eļļu saturošu uztura bagātinātāju peroksīdu līmeņa un cenu analīze

2017

Zivju eļļu uztura bagātinātāju popularitāte arvien pieaug to veselības ieguvumu dēļ, pateicoties eikozapentaēnskābei (EPS) un dokozaheksaēnskābei (DHS). Tā ir laba alternatīva, ja uzturā netiek lietotas zivis. Tomēr polinepiesātinātās taukskābes ir viegli oksidējamas un ir bažas par to iespējamo negatīvo efektu. Maģistra darba mērķis bija izpētīt Latvijas aptiekās pieejamo zivju eļļu uzturu bagātinātāju primārās oksidācijas līmeni un cenu diapazonu. Darba gaitā noskaidrojām, ka Latvijas aptiekās ir pieejami vairāk nekā 40 zivju eļļas uztura bagātinātāji. Jodometriskā titrēšana tika izmantota peroksīda līmeņa noteikšanai 14 paraugiem, savukārt cenu analīze - 34 preparātiem. Darba rezultātā k…

Eight-week consumption of milk enriched with omega 3 fatty acids raises their blood concentrations yet does not affect lipids and cardiovascular dise…

2014

Adequate concentrations of omega 3 fatty acids (FA) may be maintained by consuming foods naturally rich in or functional foods enriched with those essential FA. We assessed the effects of an 8-week consumption of milk enriched with 400. mg of omega 3 FA on blood lipid levels and selected cardiovascular risk factors in adult healthy volunteers. Participants (n= 157) were randomized to consume - for eight weeks - either 500. mL/day of 1% fat milk providing 150. mg of eicosapentaenoic (EPA), 150. mg of docosahexaenoic (DHA), and 100. mg of α-linolenic (ALA) acids or 500. mL/day of non-enriched 1% fat milk. At week 8, we observed significant increments of blood EPA and DHA in the intervention g…
