Shift work eating tips:Whole grain, carbohydrate-based and low-fat foods tend to make us sleepy, which makes them an excellent choice for a meal before bed. Protein-rich foods keep us alert, which makes them a good choice for meals and snacks eaten during an evening or night shift.
Not surprisingly, night shift workers often struggle with feelings of drowsiness and making the right food choices can help. Protein foods like tuna, eggs, string cheese, cottage cheese, peanut butter, turkey, and tofu can help increase alertness and focus, so try to incorporate these into your meals and snacks.
