We are all aware that our dietary choices impact more than just our weight; they significantly affect our overall health. Similarly, our beverage choices are equally important for maintaining brain health. While some drinks may seem harmless, they can hasten cognitive decline, contribute to memory issues, and are associated with serious conditions like stroke and dementia. However, occasional indulgence in drinks like soda won’t harm brain function, but overconsumption can be detrimental. Nutritionist Rania Batayneh, MPH, author of The One One One Diet, emphasizes, “I never advise clients to completely eliminate any food or drink.” She further explains, “The overall pattern of consumption is what truly matters. One soda or latte isn’t problematic, but habitual excessive consumption, especially alongside an ultra-processed diet, can accelerate brain aging. Setting consumption limits can safeguard brain health, making a significant difference.” Here are five beverages that, according to Batayneh, could potentially speed up brain aging.
Sugary Sodas
While an ice-cold soda is refreshing on a warm day, consuming as few as two cans weekly might affect heart health negatively, regardless of physical activity, as elucidated by a 2024 study in the American Journal of Clinical Nutrition. Batayneh notes, “Regular soda intake over time triggers repeated spikes in blood sugar and insulin, promoting inflammation.” Research links soda consumption to reduced brain volume and impaired memory. When paired with a processed food diet, the impact on brain health can escalate.
Energy Drinks
Energy drinks provide a quick energy boost but might harm your brain. Batayneh states, “Many rely on energy drinks as their sole caffeine source, sometimes even substituting them for breakfast, which floods the body with stimulants but deprives the brain of the steady energy it would typically obtain from a balanced meal.”
She explains, “The result is poor blood sugar control, a lack of sustained energy, and a bigger crash later in the day. Over time, this pattern places constant stress on the nervous system and makes the brain more vulnerable to decline.”
Excessive Intake of Alcohol
According to the National Institute on Alcohol Abuse and Alcoholism, heavy drinking is defined as four or more drinks in a day for women, or eight or more a week, and five or more drinks a day for men, or 15 or more per week. “Excessive drinking shrinks brain volume, especially in the hippocampus, which is critical for memory and learning,” says Batayneh. She adds, “Alcohol also interferes with the absorption of vitamins that protect cognitive health. Over time, heavy drinking raises the risk of earlier memory loss and cognitive decline.”
Diet Sodas
Many turn to diet soda, thinking it’s a healthier option than regular soda, but it is not. “Diet soda skips the sugar but comes with its own concerns,” says Batayneh. “Artificial sweeteners can interfere with gut bacteria and blood sugar regulation, both of which are tied to brain health.” She explains, “Studies suggest that drinking diet soda regularly is linked to a higher risk of stroke and dementia. If the rest of the diet is also heavily processed, the risks add up.”
Sweetened Coffee Drinks
Coffee drinkers who love those sugary seasonal drinks, beware. “Coffee itself contains antioxidants that support brain health, but sugary coffee drinks undo those benefits,” Batayneh explains. “Syrups, whipped cream, and flavorings turn coffee into a dessert. Over time, drinking these daily causes blood sugar spikes and inflammation that chip away at focus, memory, and energy.”
The Takeaway
Moderation is key and daily healthy habits do matter. “It is not one drink that makes or breaks brain health, it is the pattern over time,” says Batayneh. “Choosing water, sparkling water, unsweetened tea, or plain coffee more often gives the brain the support it needs to stay sharp and resilient.”
