Maintaining optimal brain health is crucial for preserving memory, cognitive function, and overall mental well-being. And one of the most important factors to consider when it comes to your brain health is your diet, which influences everything from cognitive performance to the risk of neurodegenerative diseases such as Alzheimer’s.
While many people focus on foods that support brain health, it’s equally important to consider the impact of what we drink. Our daily beverage choices can either nourish our brains or contribute to cognitive decline. Neuroscientist Dr. Robert Love, an expert in Alzheimer’s prevention, recently sheds light on three popular ‘healthy’ drinks that may actually be detrimental to our brains, offering insights and alternatives to help safeguard cognitive health. Read on to learn about the risks of red wine, sports drinks, and coffee.
1. Red Wine
Dr. Love begins with a beverage that a lot of us would hate to give up: red wine. "I’m really sorry about this one, because I really enjoy it myself–at least I did–it is red wine," he confesses. Although red wine has been praised for its heart health benefits due to its antioxidant content, its effects on the brain are less favorable. "Red wine tastes good and feels good, and there was research to show that it is good for heart health. But, the research on the brain is pretty clear: wine and alcohol in general harms the gut bacteria, harms the liver, and increases inflammation."
Alcohol consumption can disrupt gut health, which is closely linked to brain function, and lead to inflammation throughout the body. Moreover, it impairs sleep and memory, two critical factors for maintaining cognitive health. Dr. Love advises moderation for those who choose to drink alcohol: "Try to reduce the amount of wine you drink to one or two nights a week and no more than one or two glasses per night."
2. Sports Drinks
Another common beverage that many health-conscious individuals turn to is sports drinks. However, Dr. Love highlights the hidden dangers these drinks pose: "Sports drinks are either high in sugar or high in artificial sugars, and both of those can be damaging to your brain." High sugar intake is linked to a range of health issues, including obesity and type 2 diabetes, which in turn can affect brain health. Artificial sweeteners, although calorie-free, have been associated with negative effects on cognitive function and gut health.
Instead of sports drinks, Dr. Love recommends hydrating with alternatives that provide electrolytes without the harmful additives. Water and coconut water are excellent choices that can keep you hydrated and healthy without the downsides of high sugar or artificial ingredients.
3. Conventional Coffee (Non-Organic)
The third drink Dr. Love warns against might be surprising, especially given its widespread consumption: conventional coffee—a.k.a. coffee that's not organic. "It’s a surprise to most people because it’s so healthy. It’s conventional coffee (not organic). Organic coffee is terrific for your brain, but conventional coffee can be sprayed with pesticides," he explains.
Coffee is one of the crops most commonly sprayed with pesticides in the United States, and these chemicals can be neurotoxic. "Pesticides can damage your neurons, your brain cells which communicate important information throughout your body," Dr. Love warns. To minimize exposure to these harmful chemicals, he recommends opting for organic coffee. "Make sure you drink organic coffee, ideally light roast coffee," he suggests, noting that organic coffee is free from neurotoxic pesticides and retains more antioxidants, which are beneficial for brain health.
Bottom line
Dr. Robert Love’s insights serve as a reminder that even beverages marketed as 'healthy' can have hidden risks, particularly for brain health. By reducing the consumption of red wine, avoiding sports drinks loaded with sugars or artificial sweeteners, and choosing organic coffee, you can better protect your cognitive function. Making informed choices about what you drink is just as important as making smart food choices. By being mindful of your beverage consumption, you can support your brain health and overall well-being, ensuring a sharper, healthier mind for years to come.
