There was a significant reduction in reported fast‑food consumption (P < 0.001). Fruits and vegetables (P < 0.001), natural fruit juices (P < 0.001), and water (P < 0.001) were consumed more frequently. Individuals also consumed more vitamin and mineral supplements ( P < 0.001) including those containing Vitamin D.
