Milkshake Impairs Brain Blood Flow Regulation
Even a Single Glass Raises Risk of Stroke or Dementia
It is widely known that foods or beverages high in saturated fat content are a major cause of cardiovascular disease. However, recent research has shown that such foods can also have an immediate negative impact on brain health in the short term.
According to international media outlets such as People, a research team from the University of New South Wales in Australia published a paper in the Journal of Nutritional Physiology stating, "Consuming high-fat foods immediately impairs the body's ability to regulate blood flow to the brain." The researchers added, "The milkshake used in the experiment is literally a 'brain bomb.'"

The researchers provided a milkshake containing approximately 1,362 kilocalories, 48 grams of carbohydrates, and 9.5 grams of protein to 20 men aged 18 to 35 and 21 men aged 60 to 80. This beverage was made by mixing 350 milliliters of heavy cream (whipping cream), two tablespoons of chocolate syrup, one tablespoon of sugar, and one tablespoon of skim milk powder.
Participants performed squat exercises before and four hours after drinking the beverage, while changes in blood flow to the brain and throughout the body were measured using ultrasound. The results showed a decrease in vascular dilation ability across all age groups. In particular, the brain's ability to autonomously regulate blood flow was significantly reduced. Among older participants, this change was about 10% more pronounced.
Weakened Brain Blood Flow Regulation... Increased Risk of Dementia and Stroke
The researchers explained, "When the brain's ability to self-regulate in response to changes in blood pressure is weakened, there can be temporary periods of excessive or insufficient blood flow. If this state persists, the risk of diseases such as stroke or dementia may increase." They further warned, "While occasionally eating high-fat meals may not lead to serious illness, even a single intake can trigger an immediate response in the body."
"Reduce Saturated Fat, Increase Unsaturated Fat"
Experts advise that reducing saturated fat intake and choosing foods rich in unsaturated fats is the key to protecting brain health. Foods such as nuts, fish, and olive oil help maintain healthy blood vessels and suppress inflammatory responses.
