Dietary profile and phenolics consumption in university students from the Ningxia Hui Autonomous Region of China

Abstract

Background Polyphenol intake assessment is a first step for evaluating relationships between polyphenols and health-related outcomes. Ningxia Hui Autonomous Region is one of the minority areas in China, which is primarily consists of arid, dry desert. Objectives This study was to make assessment about phenolics intake by university students from Ningxia of China. Methods This study employed data from a cross-sectional survey conducted from February to June 2018 in Ningxia Hui Autonomous Region of Northwest China. A total of 413 undergraduate students (143 boys, 270 girls), mean age 20.6 years, participated in the study. Food-frequency consumption and anthropometric measurements were included in the survey. According to phenol-explorer website, the amount of different classes of phenolic compounds were established. Statistics analyses were conducted with IBM SPSS 20.0. Results Profile of the student subjects showed low weight (19.1%), overweight (6.8%) and obesity (0.5%). The mean value about phenolics intake was 1378 mg/day. The main polyphenols consumed were flavonoids (58.7% of total polyphenols), followed by phenolic acids (38.1%). Vegetables, fruits and cereals products were the most consumed foods, while infusions and sugar products were lower. Fruit was the main food sources of total polyphenols, especially apple (22.95%), orange juice (19.03%) and apple juice (3.93%). Conclusions This is the first study on the polyphenol intake of university students in Ningxia of China. The present results will be benefit for further investigation on the role of polyphenol intake against disease occurrence for this adults group.

Ethnic differences in eating patterns and their associations with obesity among adults in West China

“…For example, the nomadic Mongolians are known for their hospitality and enthusiasms for alcohol and milk tea, in which sugar and salt are commonly added (12) . On the contrary, Hui people mostly believe in Islam, who put an emphasis on abstinence and consider drinking and overeating as a violation of the Islamic doctrine (13) . This may explain why more Mongolians were found to adopt the ‘indulgent’ pattern, while Hui tended to be less ‘indulgent’ but more ‘nutri-health-concerned’.…”

Riesgo cardiovascular y consumo de polifenoles en estudiantes de área básica de Nutrición

“…Respecto al consumo de polifenoles en estudiantes universitarios son escasos, uno de estos estudios fue realizado en 413 estudiantes universitarios de Ningxia, China y reportó un consumo promedio de polifenoles totales de 1,378 mg/día (Gao et al, 2020); otro estudio, pero realizado en 270 estudiantes universitarios de España, estimó que el consumo promedio fue 1,500 mg/día (Rodríguez, 2020), mientras que un estudio local realizado en Yucatán, México reportó un consumo de 1,251 mg/día (Marín-Canul, 2023). En los tres casos, los flavonoides fueron la clase de polifenol de mayor consumo, seguido de ácidos fenólicos; adicionalmente los estudios coinciden en que los alimentos que más contribuyeron al aporte de polifenoles fueron las frutas y los vegetales (Gao et al, 2020;Rodríguez-Laguna et al,2020;Marín-Canul et al, 2023). De estos reportes, sólo el realizado en España también evaluó la asociación entre el consumo de polifenoles e indicadores de riesgo cardiovascular, sin encontrar una asociación estadística (Rodríguez, et al, 2020).…”
