High-Fat Milkshakes Found to Harm Brain Health, Study Reveals

A recent study has revealed that consuming a high-fat milkshake can negatively affect brain health. Researchers found that the drink, often considered a treat, could impair blood flow to the brain, potentially increasing the risk of conditions such as stroke and dementia. The findings were published in The Journal of Nutritional Physiology and highlight the importance of diet on mental well-being.

The study involved two groups of men: 20 participants aged between 18 and 35, and 21 others aged 60 to 80. Each participant consumed a milkshake containing 1,362 calories, along with 48 grams of carbohydrates and 9.5 grams of protein. The ingredients included heavy whipping cream, chocolate-flavoured syrup, granulated sugar, and non-fat dry milk. Researchers referred to this high-fat beverage as a “brain bomb” during discussions of their findings in The Conversation.

Researchers conducted ultrasounds to assess blood flow before and after the consumption of the milkshake. Four hours after drinking, while performing squats, blood flow was measured again. The results confirmed earlier research indicating that a high-fat meal impairs the ability of blood vessels related to heart health to function properly, affecting both younger and older participants.

The study found that the negative effects were more pronounced in the older group, suggesting that older brains may be more susceptible to the adverse impacts of a high-fat meal. While the researchers stated that an occasional high-fat meal is “unlikely to cause harm,” they emphasized that even a single fatty meal has immediate consequences on the body.

Researchers noted, “Our findings confirm previous research that has shown that a high-fat meal impairs the ability of the blood vessels linked to heart health to open in both young and old participants.” They warned about the immediate effects of such meals, stating, “Even one fatty meal has an immediate effect on the body.”

The importance of maintaining a diet low in saturated fats was underscored, as it can protect both heart and brain health. The researchers emphasized that this advice is particularly significant for older adults, whose brains are already at an increased risk for stroke and neurodegenerative diseases.

“Diet doesn’t just shape our long-term health,” they stated. “It also affects our body and brain in real time. When it comes to protecting brain health, every meal may count.”

The study serves as a reminder of the relationship between diet and cognitive function, encouraging individuals to be mindful of their food choices to support overall health.
