Assessment of the temporal trend and daily profiles of the dietary purine intake among Chinese residents during 2014 to 2021

Abstract

The incidence of hyperuricemia is on the rise in China, primarily due to dietary habits. However, limited data exists regarding dietary purine intake in the country. This study aimed to estimate the daily dietary purine intake among Chinese residents from 2014 to 2021 and evaluate the temporal trend using joinpoint regression analysis. The analysis revealed an annual percentage change (APC) of 0.8% (95% CI: 0.1–1.5%) in dietary purine intake prior to the joinpoint (2014–2019). Following the joinpoint (2019–2021), the APC significantly increased to 6.5% (95% CI: 3.3–9.8%), indicating a noteworthy upward trend (p = 0.045). Furthermore, the average daily purine intake varied significantly among different regions of China, with the southern region showing the highest dietary intake of purines. Considering the diverse contributions of various food sources to dietary purine intake, it was observed that meat consumption had the greatest impact, accounting for 36.2% of purine intake, followed by cereals consumption (25.3%) and vegetables and edible fungi (24.2%). These findings hold significance for dietary intervention and management strategies aimed at reducing purine intake among the population.

Priestia megaterium ASC-1 Isolated from Pickled Cabbage Ameliorates Hyperuricemia by Degrading Uric Acid in Rats

“…Its prevalence can be affected by excessive intake of high purine and high fructose foods [6,14]. Previous research has shown that hyperuricemia is more prevalent in coastal areas due to excessive purine intake [38][39][40].…”

Sacha inchi albumin delays skin‐aging by alleviating inflammation, oxidative stress and regulating gut microbiota in d‐galactose induced‐aging mice

“…After 6 weeks’ successful modeling, the NC and SLM groups were treated with normal chow diet, and the treatment groups were orally administered with normal chow diet (the analysis of the nutritional content of the daily diet is shown in the supporting information, Table S3) with low‐(LMTD, 83.3 mg kg −1 bw day −1 ) and with high‐dose sacha inchi albumin (HMTD, 166.7 mg kg −1 bw day −1 ). The high‐dosage of SIA was determined based on the daily maximum protein intake (55 g d −1 ) for human adults (60 kg) adjusted according to the actual average weight for the mice and was calculated as 55 × 9.01/60 × 0.02018 = 166.7 mg kg −1 bw day −1 , 28,29 the low‐dose group was half the high‐dose one, according to the previous report 30 . They were allowed access to water and food ad libitum for 6 weeks during which the bodyweight and food intake were recorded daily for each rat.…”
