BACKGROUND: Evidence from animal models and observational studies in humans has suggested that there is an inverse relationship between dietary intake of omega 3 long-chain polyunsaturated fatty acids (LCPUFA) and risk of developing age-related macular degeneration (AMD) or progressing to advanced AMD. OBJECTIVES: To review the evidence that increasing the levels of omega 3 LCPUFA in the diet (either by eating more foods rich in omega 3 or by taking nutritional supplements) prevents AMD or slows the progression of AMD. SEARCH METHODS: We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (The Cochrane Library 2012, Issue 4), MEDLINE (January 1950 to April 2012), EMBASE (January 1980 to April 2012), Latin American and Caribbean Literature on Health Sciences (LILACS) (January 1982 to April 2012), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com), ClinicalTrials.gov (www.clinicaltrials.gov) and the WHO International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). We did not use any date or language restrictions in the electronic searches for trials. The electronic databases were last searched on 26 April 2012. SELECTION CRITERIA: We planned to include randomised controlled trials (RCTs) where increased dietary intake of omega 3 fatty acids was compared to placebo or no intervention with the aim of preventing the development of AMD, or slowing its progression. DATA COLLECTION AND ANALYSIS: Both authors independently screened titles, abstracts and full-texts of articles to identify studies for inclusion and analysis. MAIN RESULTS: No trials met the selection criteria. The results of a large, multi-centre, randomised trial (AREDS2) that will assess the effects of oral supplementation with omega 3 LCPUFA on progression to advanced AMD are expected in 2013. Two further trials are also ongoing.  AUTHORS’ CONCLUSIONS: Until data from RCTs become available for analysis, there is currently no evidence to support increasing levels of omega 3 LCPUFA in the diet for the explicit purpose of preventing or slowing the progression of AMD.

Skipping breakfast: Morningness-eveningness preference is differentially related to state and trait food cravings.

Eveningness preference is associated with unhealthy eating behaviors. We measured state and trait food cravings in chronotypes in the morning and in the evening. Less Evening (E)- than Morning (M)-types reported to have had breakfast. Accordingly, hours that had elapsed since the last meal were higher in E- than M-types in the morning, but did not differ between groups in the evening. E-types reported higher anticipation of positive reinforcement that may result from eating than M-types in the morning, but both had the same hunger levels. On a trait level, M-types reported more feelings of guilt for giving into cravings compared to E- types. Results suggest that E-types skip breakfast more often than M-types, but this eating pattern does not inevitably lead to more food cravings in the evening or more pronounced habitual cravings. Furthermore, E-types did not experience more hunger in the morning although they had not been eating for a longer time period. Results support findings about a different lifestyle in E-types compared to M-types.

A higher alkaline dietary load is associated with greater indexes of skeletal muscle mass in women.

Conservation of muscle mass is important for fall and fracture prevention but further understanding of the causes of age-related muscle loss is required. This study found a more alkaline diet was positively associated with muscle mass in women suggesting a role for dietary acid-base load in muscle loss. INTRODUCTION: Conservation of skeletal muscle is important for preventing falls and fractures but age-related loss of muscle mass occurs even in healthy individuals. However, the mild metabolic acidosis associated with an acidogenic dietary acid-base load could influence loss of muscle mass. METHODS: We investigated the association between fat-free mass (FFM), percentage FFM (FFM%) and fat-free mass index (FFMI, weight/height(2)), measured using dual-energy X-ray absorptiometry in 2,689 women aged 18-79 years from the TwinsUK Study, and dietary acid-base load. Body composition was calculated according to quartile of potential renal acid load and adjusted for age, physical activity, misreporting and smoking habit (FFM, FFMI also for fat mass) and additionally with percentage protein. RESULTS: Fat-free mass was positively associated with a more alkalinogenic dietary load (comparing quartile 1 vs 4: FFM 0.79 kg P?HubMed – eating

 

Fetal growth, omega-3 (n-3) fatty acids, and progression of subclinical atherosclerosis: preventing fetal origins of disease? The Cardiovascular Risk in Young Finns Study.

BACKGROUND: Impaired fetal growth is independently associated with an increased risk of cardiovascular events in adulthood. Prevention strategies that can be implemented during adulthood have not been identified. OBJECTIVE: The objective was to determine whether habitual omega-3 (n-3) fatty acid intake is associated with the rate of increase of carotid intima-media thickness during adulthood in individuals with impaired fetal growth. DESIGN: This was a population-based, prospective cohort study of 1573 adults in Finland. Carotid intima-media thickness was assessed in 2001 (at ages 24-39 y) and in 2007. Participants were categorized as having had impaired fetal growth (term birth with birth weight <10th percentile for sex or preterm birth with birth weight <25th percentile for gestational age and sex; n = 193) or normal fetal growth (all other participants; n = 1380). Omega-3 fatty acid intake was assessed by using a food-frequency questionnaire and on the basis of serum fatty acid concentrations. RESULTS: In multivariable models, the 6-y progression of carotid intima-media thickness was inversely associated with dietary omega-3 fatty acids in those with impaired fetal growth (P = 0.04). Similarly, serum omega-3 fatty acid concentrations were inversely associated with the 6-y progression of carotid intima-media thickness in those with impaired fetal growth (P = 0.04) but were not noted in those with normal fetal growth (P = 0.94 and P = 0.26, respectively). CONCLUSION: Dietary intake of omega-3 fatty acids is associated with a slower rate of increase in carotid intima-media thickness in those with impaired fetal growth. HubMed – eating

 

 

The Female Body & The Psychology of Eating Disorders Part 1 – Dr. John Breeding, Ph. Psychologist discusses eating disorders including anorexia, bulimia, and over-eating. Dr. Breeding discusses how problems w/ eating are the norm in American Society.
