Beyond Calories: The Broader Health Benefits
The reason blueberries are so highly regarded in nutritional circles goes far beyond their low-calorie density. They are often labeled a "superfood" due to their rich composition of beneficial compounds.

- Brain Health: Some studies suggest that regular consumption of blueberries can improve cognitive function, including memory and reaction times, especially in older adults.
- Blood Sugar Management: Blueberries have a low glycemic index, meaning they won't cause major spikes in blood sugar. Their bioactive compounds may also improve insulin sensitivity, which is beneficial for managing blood sugar levels.
- Weight Management: The combination of low calories and high fiber can help with appetite control, making you feel full and satisfied for longer. This makes them an excellent component of a weight-loss or maintenance diet.
