Dietary Omega-3 Fatty Acids and Improvement of Visual Acuity in School -Age Children
ثبت نشده
چکیده
Previous studies have supported the benefit of increased intakes of DHA (docosahexaenoic acid) omega-3 fatty acid during pregnancy and lactation (or via infant formula) on visual acuity in infants and young toddlers. The present study was directed to investigate the potential benefit of enhanced dietary omega-3 fatty acid intakes in children ages 7-12 on visual acuity. The study population comprised of 179 children (average age being 9.6 years) of whom 88 had lower IQs and 91 had ADHD (attention-deficit hyperactivity disorder). The children were randomized to the omega-3 group (consuming an omega-3 egg daily markedly enriched in alpha-linolenic acid plus DHA) or a ‘regular’ egg (very low levels of omega-3 fatty acids). Before and after consuming the eggs each day for a period of 3 months, blood measures of omega-3 fatty acids were performed by gas-liquid chromatography as well as optical assessments for visual acuity.

The Association of Omentin Gene Expression in Visceral and Subcutaneous Adipose Tissues with Plasma Fatty Acids Profile and Dietary Fatty Acids
Introduction: Omentin, an adipokine, with anti-inflammatory effects reduces insulin resistance, and can hence, play an important role in prevention of cardiovascular disease and diabetes. The present study aimed to investigate the association of plasma and dietary fatty acids with gene expression of omentin in visceral and subcutaneous adipose tissues. Materials and Methods: Visceral and subcut...
متن کاملThe Effect of Omega-3 Fatty Acids on Serum Apelin Levels in Cardiovascular Disease: A Randomized, Double-Blind, Placebo-Controlled Trial
Background: Cardiovascular disease (CVD) is the leading cause of mortality worldwide. Omega-3 fatty acids have been shown to have both anti-atherogenic and anti-inflammatory effects through inducing the expression and production of adipokines. Adipokines such as apelin, have been observed to play a protective role in the incidence and progression of CVD. The aim of this study was to assess the ...
متن کاملP-14: In Vitro Comparison of Different Dietary Omega-3/Omega-6 Fatty Acid Ratios and Vitamin E on The Rat Semen Quality
Background: Beneficial effects of omega-3 polyunsaturated fatty acids (PUFAs) on the male fertility are widely described in the literature. However, there is little information about the effect of dietary n-3/n-6 ratios and Vit E on the male reproduction. The aim of this study was to evaluate the influence of dietary PUFAs on the rat sperm characteristics after eight weeks oil consumption. Mate...

Age-related macular degeneration (AMD) is the primary cause of blindness in individuals older than 50 years of age. Studies were carried in patients with dry AMD using high-dose omega-3 fatty acids providing 3.4 g of eicosapentaenoic acid (EPA) and 1.6 g of docosahexaenoic acid (DHA) on a daily basis for 6 months. In patients with dry AMD, significant improvement in vision acuity occurred in 10...
