Background and study aims
Food bank users are often food insufficient and have poorer diet quality compared to non-users. Food parcels, supplied to food bank users, provide an opportunity to improve their diets. However, the content of these food parcels is not in line with dietary recommendations. This suggests that the nutritional guidelines for a healthy diet cannot be met if food supplied by food banks is the sole food source, which consequently may lead to higher risks on nutrition related chronic diseases. Therefore, we aimed to assess whether improving the nutritional quality of the food parcels, by adding healthy foods and removing unhealthy foods, will positively impact diet quality of food bank recipients.
Who can participate?
All food bank recipients of three selected food banks in the Netherlands (i.e. Alkmaar, Apeldoorn and Enschede) could participate if they were at least 18 years old, recipients for at least one month, possible to contact by phone, collect their own food parcel, and if they had an adequate command of the Dutch language to participate in oral and written interviews.
What does the study involve?
We performed a randomized controlled trial with cross-over design with two consecutive periods, lasting 4 weeks each. Per food bank, participants were randomly assigned to one of the six possible diet sequences. The study consisted of the following intervention conditions:
1. The control condition: the standard food parcel, with an additional non-food item.
2. Experimental condition 1: the standard food parcel in which snacks were replaced by staple foods, with an additional non-food item.
3. Experimental condition 2: the standard food parcel with additionally the recommended daily amount of fruit and vegetables for all household members for 7 days (4 days fresh, and 3 days non-perishable vegetables).
4. Experimental condition 3: the standard food parcel in which snacks were replaced by staple foods with additionally the recommended daily amount of fruit and vegetables for all household members for 7 days (4 days fresh, and 3 days non-perishable vegetables).
What are the possible benefits and risks of participating?
A possible benefit of the study is a healthier dietary intake. There are no side effects.
Where is the study run from?
The study was run from the Vrije University Amsterdam, Amsterdam, The Netherlands. Participating food banks were Alkmaar, Apeldoorn and Enschede, where measurements took place.
When is the study starting and how long is it expected to run for?
The study started 18 October 2012 and ended 10 January 2013. Per food bank, the study lasted 8 weeks.
Who is funding the study?
The study, which is part of the Food Bank Study, was funded by a grant from the Netherlands Organization for Health Research and Development (115100003)

| Intervention | We performed a randomized crossover controlled trial with two consecutive periods, lasting 4 weeks each. Per food bank, the trial lasted 8 weeks in total. Per food bank, participants were randomly assigned by hand to one of the ten following possible sequences: 1. control condition - experimental condition 1 2. control condition - experimental condition 2 3. control condition - experimental condition 3 4. experimental condition 1 - control condition 5. experimental condition 1 - experimental condition 3 6. experimental condition 2 - control condition 7. experimental condition 2 - experimental condition 3 8. experimental condition 3 - control condition 9. experimental condition 3 - experimental condition 1 10. experimental condition 3 - experimental condition 2 The trial consisted of the following intervention conditions: 1. The control condition: the standard food parcel supplied by the food bank with an additional non-food item. 2. Experimental condition 1: the standard food parcel supplied by the food bank in which snacks (e.g. potato chips, cookies, chocolate) were replaced by staple foods (e.g. pasta, rice), with an additional non-food item. 3. Experimental condition 2: the standard food parcel supplied by the food bank with additionally the recommended daily amount of fruit (2 pieces) and vegetables (200 grams) for all household members for 7 days (4 days fresh, and 3 days non-perishable vegetables). 4. Experimental condition 3: the standard food parcel supplied by the food bank in which snacks (e.g. potato chips, cookies, chocolate) were replaced by staple foods (e.g. pasta, rice) with additionally the recommended daily amount of fruit (2 pieces) and vegetables (200 grams) for all household members for 7 days (4 days fresh, and 3 days non-perishable vegetables). |

| Primary outcome measure | Differences in dietary intake of the following food groups and nutrients (based on the Dutch Food Composition Table) between the intervention conditions were measured with multiple 24 hour recalls per participant at the end of each intervention condition (after 4 and after 8 weeks): Nutrients: 1.Energy (kcal) 2. Protein (en%) 3. Mono- and disaccharides (en%) 4. Polysaccharides (en%) 5. Total fat (en%) 6. Saturated fat (en%) 7. Dietary fiber (g) 8. Vitamin C (mg) 9. Sodium (g) 10. Potassium (mg) Food groups: 1. Vegetables (g) 2. Soya and vegetarian products (g) 3. Sugar, candy, sweet filling and sweet sauces (g) 4. Pastry and cookies (g) 5. Nuts, seeds and snacks (g) 6. Grains, flour, rice (g) 7. Fruit (g) We did not calculate an overall score as a measure of diet quality. Therefore, the above mentioned outcomes are the primary outcomes. |
