Why This Study Matters


As a nurse and shift-work researcher, I’ve seen firsthand how long hours reshape not just our sleep and stress—but our nutrition. This new study from Türkiye provides critical insight into how 24-hour shifts affect healthcare workers’ nutrient intake and recovery, an issue that continues to go largely unaddressed in clinical practice.


Study Snapshot

Study Type

Observational follow-up

Participants

500 healthcare professionals (nurses, physicians, EMTs)

Design

Three-day dietary tracking (pre-shift, shift day, post-shift)

Focus

Energy, macro/micronutrient intake, and food group consumption

Key Findings


1. Energy Intake Peaks During the Shift, Then Plummets

  • Shift Day: 2,399 kcal

  • Pre-Shift: 2,130 kcal

  • Post-Shift: 1,749 kcal


After a 24-hour shift, calorie and macronutrient intake drops sharply—likely due to fatigue and disrupted appetite cycles.

2. Micronutrient Deficits Post-Shift

  • Calcium: 55% of DRI (vs. 71% pre-shift)

  • Fiber: 65% of DRI

  • Folate: Only 67% of recommended intake


These deficiencies carry long-term implications for bone density, immunity, and cardiovascular health.

3. Food Choices Reflect Exhaustion

Consumption of meat, dairy, and vegetables peaked during shifts, while fruit intake was highest pre-shift. Post-shift, all food groups declined—suggesting workers are too depleted to prepare balanced meals.


What It Means for Healthcare Workers


Nutrient Deficiency Awareness

Chronic under-nutrition following shifts can quietly erode well-being. Deficits in calcium, fiber, and folate may increase the risk of osteopenia, immune dysfunction, and digestive disorders—issues commonly reported by long-term shift workers.


Nutritional Interventions

  • Pre-Shift: Eat nutrient-dense, high-fiber meals (leafy greens, dairy, whole grains).

  • During Shift: Offer access to healthy, portable foods (yogurt, nuts, seeds).

  • Post-Shift: Prioritize easy, nutrient-rich recovery meals to restore depleted stores.


Institutional Recommendations


1. Supportive Nutrition Environments

  • Provide 24/7 healthy cafeteria options rich in calcium, fiber, and folate.

  • Create meal-prep stations or refrigerated grab-and-go sections for staff.

  • Offer nutrition education tailored to shift workers.


2. Integrate Wellness and Monitoring

  • Pair nutritional guidance with mental health and stress-reduction programs.

  • Conduct routine nutritional screenings and adjust recommendations by shift schedule.


The Hidden Cost of Shift Work

This study reinforces what many frontline professionals already know:

“Shift work doesn’t just disrupt sleep—it disrupts biology.”

Without targeted nutritional strategies, healthcare workers remain vulnerable to cumulative health decline. Addressing these deficits isn’t a luxury—it’s a professional obligation for institutions committed to sustainable care.
