A driver who is hungry loses focus faster, and that drop in concentration can raise the chances of a crash. This point was explained by Dr. Anna Krivosheeva, an endocrinologist and nutritionist at Medsi CDC in Belorusskaya, in an interview conducted for socialbites.ca.
Experts advise against driving on an empty stomach. Low blood sugar can trigger weakness and dizziness, making it harder to stay alert behind the wheel. Hunger can dominate thoughts about food, pulling attention away from the road and increasing the risk of an accident. Conversely, eating very large meals or overeating can cause sleepiness and fatigue. Abdominal discomfort, heartburn, and gas may also sap focus, further compromising driving performance.
Dr. Krivosheeva notes that a person who drives while hungry may see a drop in performance by more than ten percent. A quick lift in energy might come from coffee or an energy drink, but the effect is short lived, typically about an hour, after which concentration and reaction time may deteriorate and elevate crash risk.
Research suggests certain foods can support mental sharpness. For example, consuming nutrient-rich fruits like blueberries has been associated with enhanced concentration and memory for several hours, thanks to antioxidant compounds. Such dietary choices can help maintain steadier attention during longer drives.
Aside from meals and snacks, staying hydrated and avoiding long, uninterrupted stretches behind the wheel can help reduce fatigue. Short pauses to stretch, hydrate, and reset the mind are simple strategies that support safer driving. Overall, a balanced approach to eating and timing can contribute to better focus, quicker responses, and fewer driving errors. These guidelines align with broader health and safety recommendations that encourage regular meals, mindful portion control, and something to sip or snack on that keeps blood sugar stable while on the road. In practice, drivers are encouraged to plan light, balanced snacks before long trips and to choose foods that promote energy without causing a heavy aftertaste or sluggishness. The goal is steady energy, clear judgment, and a calm, alert state of mind while traveling.”
