Background: Are dietary patterns, substantiated by biomarkers, associated with semen quality? Materials and Methods: In 161 men of subfertile couples undergoing in vitro fertilization treatment in a tertiary referral clinic in Rotterdam, the Netherlands, we assessed nutrient intakes and performed principal component factor analysis to identify dietary patterns. Total homocysteine (tHcy), folate...

Little is known about the dietary patterns of Asian populations aged >=85 years and their associated factors. Thus, we aimed to (1) identify these dietary patterns and (2) clarify the relationships between the dietary pattern and health outcomes in a community-dwelling very old population.

Banana peel flour (BPF) prepared from green or ripe Cavendish and Dream banana fruits were assessed for their total starch (TS), digestible starch (DS), resistant starch (RS), total dietary fibre (TDF), soluble dietary fibre (SDF) and insoluble dietary fibre (IDF). Principal component analysis (PCA) identified that only 1 component was responsible for 93.74% of the total variance in the starch ...

BACKGROUND Analysis of dietary pattern is increasingly popular in nutritional epidemiology. However, few studies have examined the validity and reproducibility of dietary patterns. We assessed the reproducibility and validity of dietary patterns identified by a food frequency questionnaire (FFQ) used in the 5-year follow-up survey of the Japan Public Health Center-Based Prospective Study (JPHC ...

BACKGROUND High-abundance plasma proteins are involved in disease-associated pathways and are useful in the diagnosis of nutritional and disease states. However, little is known about how concentrations of many plasma proteins vary between individuals from different ethnocultural groups with different dietary habits. OBJECTIVE We explored the association between plasma proteomic groups, dieta...
