'100% 과일주스'의 배신…섭취 후 결과 '충격'

생과일 영양소를 편리하게 섭취할 수 있는 100% 과일주스가 청소년은 물론 성인의 체중을 증가시킬 수 있어

섭취량을 제한할 필요가 있다는 연구 결과가 나왔다.

캐나다 토론토대 바산티 말릭 교수팀은 17일 미국의학협회(AMA) 학술지 JAMA 소아과학(JAMA Pediatrics)에서

어린이 대상 연구 17건과 성인 대상 연구 25건에 대한 체계적 검토와 메타 분석에서 100% 과일주스 섭취와

어린이·성인 체중 증가 사이에 연관성을 확인했다며 이같이 밝혔다.

Abstract

Importance: Concerns have been raised that frequent consumption of 100% fruit juice may promote weight gain. 

Current evidence on fruit juice and weight gain has yielded mixed findings from both observational studies and clinical trials.

Objective: To synthesize the available evidence on 100% fruit juice consumption and body weight in children and adults.

Data sources: MEDLINE, Embase, and Cochrane databases were searched through May 18, 2023.

Study selection: Prospective cohort studies of at least 6 months and randomized clinical trials (RCTs) of at least 2 weeks assessing 

the association of 100% fruit juice with body weight change in children and adults were included. 

In the trials, fruit juices were compared with noncaloric controls.

Data extraction and synthesis: Data were pooled using random-effects models and presented as β coefficients with 95% CIs 

for cohort studies and mean differences (MDs) with 95% CIs for RCTs.

Main outcomes and measures: Change in body mass index (BMI; calculated as weight in kilograms divided by height in 

meters squared) was assessed in children and change in body weight in adults.

Results: A total of 42 eligible studies were included in this analysis, including 17 among children (17 cohorts; 0 RCTs; 45 851 children; 

median [IQR] age, 8 [1-15] years) and 25 among adults (6 cohorts; 19 RCTs; 268 095 adults; median [IQR] age among cohort studies, 

48 [41-61] years; median [IQR] age among RCTs, 42 [25-59]). Among cohort studies in children, each additional serving per day of 100% 

fruit juice was associated with a 0.03 (95% CI, 0.01-0.05) higher BMI change. 

Among cohort studies in adults, studies that did not adjust for energy showed greater body weight gain (0.21 kg; 95% CI, 0.15-0.27 kg) 

than studies that did adjust for energy intake (-0.08 kg; 95% CI, -0.11 to -0.05 kg; P for meta-regression <.001). RCTs in adults found no 

significant association of assignment to 100% fruit juice with body weight but the CI was wide (MD, -0.53 kg; 95% CI, -1.55 to 0.48 kg).

Conclusion and relevance: Based on the available evidence from prospective cohort studies, in this systematic review and meta-analysis, 

1 serving per day of 100% fruit juice was associated with BMI gain among children. Findings in adults found a significant association 

among studies unadjusted for total energy, suggesting potential mediation by calories. Further trials of 100% fruit juice and 

body weight are desirable. Our findings support guidance to limit consumption of fruit juice to prevent intake of excess calories and weight gain.
