Healthy Eating For Shift Workers

Shift work is becoming increasingly common in Australia, with approximately 1.7 million Australians engaged in some form of shift work as of 2017. This type of work involves being active or awake during hours when most people are typically sleeping, disrupting the body’s natural circadian rhythm.

Understanding Our Body Clock

Our body clock, also known as the Circadian clock, regulates various functions such as eating, working, and sleeping based on natural light-dark cycles. When this rhythm is disturbed due to shift work, it can lead to difficulties in sleeping, increased stress, and alterations in eating patterns. Shift workers often resort to consuming high-sugar, high-fat, and high-calorie foods and drinks to stay awake and alert during non-standard hours.

Health Risks Associated with Shift Work

Research indicates that shift workers are at higher risk of developing several health conditions compared to day-time workers, including heart disease, type 2 diabetes, and obesity. Even with similar diet and exercise habits, shift workers may experience metabolic changes due to disrupted eating and sleeping patterns. For instance, studies show that the body’s ability to metabolize food energy diminishes after 8 pm, potentially contributing to weight gain over time.

Factors Influencing Food Choices Among Shift Workers

Several factors influence the food choices of shift workers:

• Energy Boost: Choosing high-sugar foods and drinks for quick energy.
• Stress Eating: Seeking comfort in calorie-dense foods during stressful shifts.
• Limited Options: Availability of unhealthy food choices in workplace settings.
• Irregular Eating Patterns: Interrupted or unscheduled breaks leading to erratic meal timings.
• Reward System: Using food as a reward mechanism after completing night shifts.

Recommendations for Managing Diet and Health

1. Timing of Meals:

   • Plan regular meals every 4-6 hours while awake.
   • Have a small meal 1-2 hours before bedtime to prevent hunger disruptions during sleep.
   • Incorporate a fasting period of approximately 5 hours during the night (between 10 pm and 6 am).

2. Food Choices:

   • Opt for high-protein foods over high-carbohydrate options during night shifts to stabilize blood sugar levels.
   • Maintain consistent meal sizes and types daily to regulate energy intake and prevent overeating.
   • Examples of high-protein, low-carbohydrate meals/snacks include chicken and avocado salad, homemade vegetable and bacon quiche, and yogurt with unsalted nuts.

3. Hydration:

   • Stay hydrated primarily with water, enhancing flavor with fruit pieces or diluted cordial.
   • Avoid sugary drinks like soft drinks, fruit juices, and flavored milk.
   • Limit caffeine consumption within 4 hours of bedtime to promote better sleep quality.
