Popcorn
Popcorn is a popular movie theater snack, easily devoured with each crunchy bite. Chances are, you’ve polished off a bucket of popcorn before the movie even ends. However, did you know that this tasty treat not only contributes to obesity but may also hinder brain function?
The main culprit is trans fat. This artificial fat is created by chemical agents to make food crispier, more fragrant, and longer-lasting. Nonetheless, trans fat is the brain’s nemesis.

Numerous studies indicate that excessive trans fat consumption can impair cognitive abilities and accelerate brain aging. A US study involving over 1,000 participants revealed that those with higher trans fat intake scored approximately 10% lower on memory tests compared to those with lower intake.
Trans fat isn’t exclusive to popcorn; other foods like frozen pizza, cream in milk tea, and margarine also contain it. Therefore, it’s essential to check product labels before purchasing. If you spot “partially hydrogenated vegetable oil,” steer clear. If you’re a popcorn enthusiast, consider making it at home to ensure a healthier treat.
Sugary Drinks
When it comes to beverages, many assume they are harmless. Yet, boba tea, cola, and fruit juices can swiftly diminish your IQ!
Sugar, particularly high-fructose corn syrup, is the unseen adversary of the brain. Some may believe that the brain requires sugar to function, but in reality, only a moderate amount is necessary. Excessive sugar consumption, especially from sugary drinks, wreaks havoc on the brain.
Research has demonstrated that a sugar-laden diet can diminish brain resilience and lead to memory loss. A University of California experiment also showed that rats fed a high-sugar diet over an extended period experienced a 40% reduction in synaptic connections in their brains, resulting in slower maze test reactions compared to rats on a low-sugar diet.
This implies that if you consume excessive sugar, your brain will struggle with “communicating,” leading to forgetfulness, sluggish reactions, and diminished focus.

Fried Foods
Who can resist fried chicken, French fries, or fried meatballs in spicy hot pot? While these dishes taste delightful, they wreak havoc on your brain! When you indulge in these fried treats, your body produces a substantial amount of free radicals, which attack brain cells, causing chronic inflammation and eventual neural damage.
More alarmingly, long-term consumption of fried foods impacts dopamine secretion—a crucial chemical for regulating happiness, focus, and learning. Overeating fried foods can decrease dopamine levels in the brain, affecting your concentration and learning abilities.
Artificial Sweeteners
Artificial sweeteners like aspartame, sucralose, and saccharin provide the illusion of sweetness without actual sugar, tricking the brain into thinking it has consumed sugar. Worse still, studies indicate that long-term consumers of artificial sweeteners experience memory loss 30% faster than non-consumers and are at an elevated risk of Alzheimer’s disease!
Additionally, artificial sweeteners disrupt the gut microbiome, causing an imbalance in this vital system. Given the gut-brain connection, any disruption to the gut microbiome negatively influences emotions and cognitive abilities.
