To smoothie or not to smoothie? A mixed-method approach of nutrition pilot intervention among individuals in opioid agonist treatment.
Article in BMC nutrition, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPatients with substance dependence typically have unhealthy diets and low degree of nutritional awareness. They frequently face nutritional deficiencies in both micro- and macronutrients, which can have a significant impact on their overall health. Incorporating more fruits and vegetables into their diet has been associated with reduction in diseases such as cardiovascular diseases and certain cancers. This mixed-method study aims to gain insight into participants' experience and feasibility of a pilot intervention of receiving 250 ml/day of fruit smoothies for a six-week period.
methodsIndividuals undergoing opioid agonist treatment in Bergen and Stavanger, Norway, were recruited for this multi-center pilot study. This study had a pre- and post-intervention design where an explanatory sequential design was employed, integrating qualitative methods to delve into patients' experiences and perspectives. In addition, psychological distress (Hopkins Symptom Checklist (SCL-10), fatigue (three-item Fatigue Severity Scale (FSS-3)), and nutrition status (folic acid) were measured.
resultsTwenty-four individuals with a mean age of 47 years (standard deviation: 8.6) participated. They expressed feeling more energetic and being more active, and some reported eating more meals than before and adding new food items to their diet. Oral health was a barrier to eating more vegetables and fruits while smoothies, on the other hand, were easy to consume even with poor dental status. There were no clear indications of changes in psychological distress (pre-test: 2.09 vs. post-test: 2.08) or fatigue (post-test: 4.19 vs. post-test: 4.43). Folic acid levels increased from 15.3 nmol/L at baseline to 17.0 nmol/L after the intervention.
conclusionReceiving fruit smoothies seems to have several benefits for patients undergoing opioid agonist treatment, including helping them reflect on their health and diet and expressing more awareness about nutrition. Providing smoothies alongside patients' opioid agonist treatment was seen as feasible and can be a door opener for clinicians to discuss nutritional issues in this population. To evaluate the effectiveness, a sufficiently powered randomized controlled trial is needed.
