Story summary

A study shows that a single high-fat meal can reduce brain blood flow, raising the risks of stroke and dementia.
Researchers from the University of South Wales tested younger and older men after they consumed a high-calorie milkshake with 1,362 calories and 130g of fat.
Older participants had higher glucose and insulin levels, indicating vulnerabilities.
Four hours later, triglyceride levels increased, impairing blood vessel flexibility and brain blood flow regulation.
The results highlight the need for a low-saturated fat diet, particularly for older adults.
