Fatigue can set in when truck driving. Often times, what you eat contributes to your alertness on the road. Some snack options might surprise you with their high drowsiness factor. High glycemic index foods are on this list. 

The Glycemic index rating system ranks food on a scale of 0 to 100.

GI Rating system: Low GI: 0-55, Medium GI: 56-69, High GI: 70 or greater.

High glycemic index (GI) foods: Release sugar into the bloodstream quickly, causing a rapid rise in blood sugar. Think: Food coma, drowsiness, weight gain. These are low fiber foods. It's easy to overeat these types of foods because they leave you feeling hungry and tired.

Low GI foods: Release sugar into the bloodstream slowly and doesn’t cause a rapid rise in blood sugar. You feel steady energy and fuller longer. These are typically rich in fiber, protein and/or fat. Examples of these include apples with a glycemic index of 28 or Greek-style yogurt at 11. Low GI doesn’t mean a food is high in nutrients. You need a balanced diet that is based on healthy foods from all food groups.

You might tend to think you’re making decent food choices when you eat foods such as graham crackers, pretzels, vanilla wafers, bagels, instant oatmeal, or rice cakes. Because let’s face it: we could do worse, right? But we could also do better.

Take a look and maybe you’ll find healthier snack options you can exchange that will help keep you alert while on the road.
