Sugary drinks, baked goods, and processed snacks cause energy crashes due to blood sugar spikes and drops, a Jan 2026 study finds.
A new study published in January 2026 identifies sugary drinks, baked goods, and processed snacks as major contributors to energy crashes and fatigue, linking their high sugar and refined carbohydrate content to rapid blood sugar spikes and subsequent drops.
Researchers from the National Institute of Health found that frequent consumption of these foods correlates with increased daytime drowsiness and reduced mental alertness, particularly in adults aged 25 to 55.
The findings reinforce dietary guidelines recommending reduced intake of added sugars and ultra-processed foods to support sustained energy levels.
