Summary

The CIRCA-CHEM study is a non-pharmacological, randomized cross-over health intervention trial studying the effect of the time of day on the metabolism and concomitant toxicity of exposures to pesticides found in a balanced fruits and vegetables diet, providing the same weekly portions of fruit and vegetables (isopesticide dietary scheme) but consumed in two different time windows (morning vs. night).

Conditions

  • Diet Habit

Interventions

BEHAVIORAL

Isopesticide dietary scheme

All participants should collect first morning urine samples on specific days during the first week and during the third week. Day indicated as "8th", represents the first day of the following week (first day of the wash-out week and first day of the fourth week which is the last day of the study). The participants are asked to consume 4 portions of fruit and 2 portions of vegetables per day during the two trial periods. Overall, dietary daily consumption of foods and fluids will be monitored with the use of a dietary diary throughout the study. Participants will also be asked to take a photograph of the ready to be consumed fruit and vegetable on actual time of consumption and share photos with research team in order to verify at a minimum whether the pre-set time-restriction criteria have been met.
