According to a 2025 study in *Nature Aging*, the protein FTL1, also known as ferritin light chain 1, was found to be a key driver of brain aging in mice. The protein FTL1 is a subunit of the larger ferritin complex, an intracellular protein responsible for storing and releasing iron. This makes FTL1 found in nearly all cells, with its specific concentration and function varying significantly depending on the tissue and physiological conditions.

Chronic overconsumption of fructose, particularly from processed foods, has been linked to impaired learning and memory in numerous animal studies. The question of what does too much fructose do to the brain is a critical public health concern as worldwide sugar intake continues to rise.

Recent studies have shown that consuming a diet high in fats and sugar can impair memory function in as little as one week. This growing body of evidence strongly suggests that junk food can cause memory and learning problems, affecting brain health far more quickly than previously understood.

A 2024 study involving over 210,000 participants from the UK Biobank found that increased sugar intake was significantly associated with a higher risk of all-cause dementia. This growing body of evidence makes many wonder: does sugar ruin your memory, and if so, what are the underlying mechanisms behind this disturbing link?

According to a 2025 study in *BMC Medicine*, excessive sugar intake was significantly associated with a higher risk of dementia. But beyond long-term risks, do sweets affect memory and cognitive function in more immediate ways? The answer lies in how different types of sugar interact with your brain's delicate systems.

According to a study published in the journal *Neuron*, a high-fat, junk food-like diet can impair memory and disrupt the brain's hippocampus in just four days. This astonishing speed reveals the immediate and profound ways that junk food affects your brain's delicate functions.
