When it comes to snacking at work, nutrition experts say the #1 rule is to avoid the carb-laden junk you usually find in a vending machine. Instead, keep your workplace fridge stocked with protein-rich foods that'll boost your energy, and give your body a short-term pick-me-up 'til dinner. So what are the best snack foods to buy? Here's what nutritionist Dr. Jonny Bowden recommends, according to Rodale publishing:* Snack food #1: Hard-boiled eggs. One egg contains a measly 78 calories and six grams of fat. They're also packed with Vitamin B, which helps break down that fat for instant energy! That means you can eat one at work, without worrying about your waistline, and as long as you keep hard-boiled eggs stored inside the shell, they'll last in the fridge for up to a week.* Another healthy workplace snack: Kosher dill pickle halves. The next time you're craving something salty and crunchy, grab one of these instead of a bag of potato chips. One pickle half holds only five calories and a single gram of carbs! That's a tiny fraction of what you'd get from even a small package of chips. Research shows that eating two tablespoons of vinegar - that's about the amount in one pickle - reduces the blood sugar spike you get after eating lunch. That can go a long way toward reducing your risk of developing type 2 diabetes.* The next snack: Fresh olives and goat cheese. One handful of olives mixed together with a couple tablespoons of goat cheese has enough protein to keep you feeling full for hours, with virtually no fat! It'll also give your body a healthy dose of oleic acid - a heart-boosting compound known to cut your risk of a heart-attack by up to 20%.* One more snack to keep stocked at work: A jar of unsalted almond butter. Research shows that almond butter contains six times the calcium as peanut butter, and three times the antioxidants! So a tablespoon of almond butter, spread over a plate full of fiber-rich apple slices, may be the best midday snack of all.
