We identified associations between self-reported olfactory dysfunction (OD) and dietary attributes in participants aged ≥40 years ( = 6,356) from the nationally representative 2011-2014 National Health and Nutrition Examination Survey (NHANES). The chemosensory questionnaire and 24-h dietary recalls were administered by trained interviewers. OD was defined as self-report of either smell problems in the last year, worse smell relative to age 25, or perceiving phantom odors. Dietary outcomes included Healthy Eating Index 2015 score (HEI) with adequacy and moderation components (higher scores indicated higher diet quality), dietary diversity, energy density, and intake of major food groups. Survey-weighted linear regression models estimated OD-diet associations, adjusting for socio-demographic, lifestyle, and clinical factors. Adjusted mean difference (95% CI) between those with versus without OD, showed that adults with OD had significantly lower HEI moderation score (-0.67 (-1.22, -0.11)) and diets higher in energy density (0.06 (0.00, 0.11)), and percent energy from saturated fat (0.47 (0.12, 0.81)), total fat (0.96 (0.22, 1.70)), and added sugar (1.00 (0.33, 1.66)). Age and sex-stratified analyses showed that younger females (40-64 years) primarily accounted for the associations with diet quality and total/saturated fat intake. These findings inform dietary screening and recommendations for adults who report OD, including those experiencing transient or persistent smell loss with COVID-19.

The effects of incorporating Illipe nut into the diet of pigs, in replacement of yellow maize, on their growth performance and meat quality was investigated in a 60 days feeding trial. Twenty-four male pigs were divided into two treatments and fed diets with 0% (T1) or 15% (T2) Illipe nut inclusion. Feed intake, live weight (LW) and backfat thickness (BFT) were taken and used to calculate average daily feed intake (ADFI), average daily gain (ADG), feed conversion ratio (FCR) and increase in backfat (IBF).

Food allergy is increasing in prevalence, and poses significant challenges for individuals and their families, adversely impacting their quality of life. Misdiagnosis can lead to unnecessary dietary and social limitations, and increased food allergy risk, while failure to diagnose may result in life-threatening anaphylaxis. Therefore, a precise diagnosis is of the utmost importance; however, barriers exist at every stage of the diagnostic process.

Grape pomace (GP) is a byproduct of the viticulture industry and shows promise for feeding dairy cattle as well as reducing enteric methane (CH) emissions. This study investigates the potential of using fresh GP in dairy cow feeding and its effects on CH emissions. Multiparous Holstein dairy cows (n = 24, 205 ± 39 DIM) were housed in free stall barns and provided rations consisting of alfalfa hay, wheat hay, almond hulls, cottonseed, and grain mix.

Background: Primary ovarian insufficiency (POI) is a critical cause of infertility and is increasingly recognized as a complex metabolic disorder. Dietary factors may influence the risk of POI, but causal relationships remain unclear.

Methods: We conducted an MR study using genetic instrumental variables for 83 dietary preferences from the UK Biobank, with the Inverse Variance Weighted method as the primary analysis.
