With summer in full swing, it's easy to reach for sodas, fruit juices, or iced teas more often—a cool sip on the terrace, by the beach, or watching the sunset. Before you know it, you're downing three or four sugary drinks a day. But research from Boston University School of Medicine warns that regular consumption of these beverages, loaded with added sugars, can impair memory. In a study involving 4,000 participants who underwent cognitive tests and MRIs over several weeks, scientists found that those drinking at least two glasses daily (soda, lemonade, iced tea, fruit juice, etc.) showed reduced memory efficiency and a smaller hippocampus—the brain region key to learning and recall. Even one glass a day was linked to memory issues. This compelling evidence underscores the need to cut back.
Governments are stepping up with targeted measures. A soda tax, in place since 2012, raises prices on drinks with added sugars to curb overconsumption. Lawmakers are also evaluating a calorie-based tax to combat obesity, penalizing high-calorie products. On a personal level, swap sugary drinks for homemade lemonade or fruit juice, infused waters (like ginger or cucumber), fresh milk, or plain water.
