Frequent fluctuations in glucose levels, or glucose variability, are known to increase the risk of a range of health conditions, including cardiovascular disease, dementia, and cancer
A recent study suggests that eating a high-protein breakfast could play a crucial role in reducing the risk of developing cancer and dementia, two major health concerns that affect millions worldwide. According to the research, consuming a meal rich in protein—specifically one containing at least 10 grams of protein—can help lower glucose variability, which has been linked to both cognitive decline and certain types of cancer.
Frequent fluctuations in glucose levels, or glucose variability, are known to increase the risk of a range of health conditions, including cardiovascular disease, dementia, and cancer. The study emphasizes that consistently high glucose variability could contribute to long-term health problems, particularly affecting brain function and overall longevity.
Lead researcher Dr. Jinger Gottschall conducted the study by having participants wear glucose monitors for two weeks while following their typical routines.
The results revealed a clear correlation between a high-protein breakfast and more stable glucose levels throughout the day. “Many people are currently unsure about what constitutes healthy glucose variability,” Dr. Gottschall said, according to Surrey Live. “But it’s vital to understand how lifestyle habits, such as diet and exercise, influence glucose fluctuations and the long-term consequences associated with them.”
In addition to the benefits of a high-protein breakfast, the research also highlights the positive effects of regular exercise, particularly intense cardio sessions twice a week. Maintaining a consistent and high-quality sleep pattern is another important factor that can help regulate glucose levels and contribute to overall health.
The study’s findings underscore the importance of making small, manageable lifestyle changes that can have a significant impact on health. Dr. Gottschall pointed out that while some people may use glucose monitoring devices to track their health, many others may not have access to such tools. However, she stressed that simple adjustments to diet and exercise routines, such as eating a protein-rich breakfast and engaging in frequent cardio workouts, can have a powerful effect on reducing glucose variability and lowering the risk of chronic diseases.

For those looking to improve their health, the study suggests that starting the day with a nutritious, high-protein meal could be an effective step toward reducing the risks associated with glucose variability. Whether or not individuals have access to tracking devices, these small, practical changes could lead to a healthier, longer life.
This study provides valuable insights into how nutrition, exercise, and sleep habits can work together to improve overall well-being, offering actionable steps to help reduce the risks of some of the most serious health conditions of our time.
