Objective: To examine the association between income and the consumption of fruits and vegetables using the poverty income ratio (PIR).
Design: Association between PIR and intake of fruits and vegetables combined. The PIR was divided into 5 groups ranging from < poverty threshold (PT) to ≥ 400% PT.
Participants: Adults aged 18 years and older (N = 16,232) who participated in the 1999-2006 National Health and Nutrition Examination Survey and fit the qualifiers.
Main Outcome Measures: The amount of combined fruit and vegetable intake based on income level.
Analyses: Using ANCOVA, a base model with increasing number of covariates was analyzed.
Results: Mean daily intake ranged from 253-324 g for those who consumed both fruits and vegetables (N = 16,213). In the base model, significant differences in intake occurred between those who were at ≥ 400% PT and PIR groups < 400. When age, sex, race/ethnicity, and calorie intake were added to the base model, these differences remained. Adding educational level to the model removed these differences.
Conclusions And Implications: Dietary intake of fruits and vegetables is directly related to income when income reaches levels of ≥ 400% PT. These differences are mediated by education. Providing nutrition education may help individuals to reach the recommended level of consumption of fruits and vegetables.

Evaluation of dietary quality in patients with functional gastrointestinal symptoms: a Norwegian single centre study.
Food Nutr Res
December 2024
Department of Clinical Support, Lovisenberg Diaconal Hospital, Oslo, Norway.
Background: Poor dietary quality has been described as a contributor to symptoms in subjects with functional gastrointestinal (GI) symptoms. Hitherto, the focus in dietary evaluation and treatment in this patient group has mainly been on avoiding individual nutrient deficiencies, and less attention has been given to the dietary pattern and the overall food quality. Hence, we aim to describe and evaluate the dietary quality in patients with functional GI symptoms.

Reactive carbonyl species (RCS) are a class of compounds with one or more C = O structures with highly reactive electrophilic properties. This comprehensive review delves into the multifaceted role of RCS in thermally processed foods, where they serve as both crucial intermediates in the development of food color and flavor, as well as precursors of potentially harmful compounds. By exploring the carbonyl pool concept, the impact of RCS equilibrium on the formation and reduction of hazardous substances such as acrylamide, hydroxymethylfurfural, advanced glycation end-products, and heterocyclic amines was elucidated.

Healthy eating habits may protect adolescents against disease development, ensure optimal physical and cognitive development, and may persist in adulthood. However, adolescents usually prefer sweetened dairy products and show a low consumption of vegetables, fruits, whole grains, and pulses. Co-creation offers an innovative and inclusive alternative for the development of new products.

This study aimed to determine 9,10-anthraquinone (AQ) levels in Indonesian tea products from different manufacturers and assess the AQ's associated health risks. AQ levels increased significantly during withering and drying stages, using pinewood as a heat source. Generally, black tea was highly contaminated by AQ followed by green tea, oolong tea, and white tea.
