Need a smart strategy to avoid a mid-afternoon energy slump? Your best bet is to fuel yourself throughout the day with light, wholesome foods. Use these tips for making nutritious choices and enjoy stamina that sticks.

• Persnickety snacking. Choosing from a vending machine can be tricky. Look for items that contain protein — such as trail mix or nuts. Take note of the calories and serving size so you don’t eat more than you need. Or better yet, try these great-tasting, packable ideas.

• Clever in the cafeteria. At the salad bar, include a small portion of nuts, seeds, beans, tofu, eggs, or cheese for protein. At the sandwich bar, order a lean meat, poultry, or vegetarian sandwich on whole grain bread. Even some pizzas, in moderation, can be nutritious and filling. Soups are often a great choice, too — just avoid the creamy varieties.
