Sticking to a healthy diet can be difficult under normal circumstances and especially difficult for security officers who may have irregular work schedules and limited access to kitchen facilities. Most security professionals work long hours and may have difficulty eating properly during the workday.

Healthy meal choices 

A key tip for maintaining a healthy diet is to plan and prepare your meals in advance. As a security guard, it is essential to focus on lean protein, high fiber foods and complex carbohydrates in your meals. Lean protein (such as chicken or tuna) allows your body to get what you need without excess calories and fat, which can be helpful if your job requires sitting for long periods of time. Sweet foods such as chocolate bars and cakes offer forms of energy that immediately reach the bloodstream, making us feel recharged. But these forms of energy are a "quick burst" and often lead to feelings of fatigue, exhaustion and nausea after their short-term effects.

Eating well in the workplace

The short-term dehydrating effects of caffeine, salty and fatty foods are strongly linked to decreased mental performance and headaches.

Instead, choose snacks that are high in protein, fibre and complex carbohydrates. Nuts, for example, are a good source of healthy fats and fiber and can help you feel full. Hummus is another option, and you can make it more nutritious by pairing it with vegetables like carrots or celery sticks instead of chips.
