Bay Leaves: A Common Spice with Studied Glucose and Lipid Effects
Bay leaves, often used in cooking for flavor, contain polyphenols and minerals that studies suggest may support metabolic health.
Research, including a study on people with type 2 diabetes consuming 1-3 grams of bay leaves daily for 30 days, showed reductions in fasting glucose levels by 21-26%, along with improvements in cholesterol and triglycerides. These effects may stem from enhanced insulin function and slower carbohydrate absorption.
Nutrients like fiber (around 26g per 100g dried) and magnesium contribute to these potential benefits by aiding digestion and metabolism. Antioxidants in bay leaves may also help combat oxidative stress affecting vessels.
Simple Bay Leaf Tea Recipe to Try
- Boil 1-2 dried bay leaves in 2 cups of water for 5-10 minutes.
- Steep, strain, and sip warm—optionally add a dash of cinnamon for flavor.
- Start with one cup daily, ideally in the morning.
Many find the earthy taste soothing and easy to incorporate.
Guava Leaves: Potential for Post-Meal Glucose Support
Guava leaves, typically from the tropical fruit tree, are rich in polyphenols like quercetin. Studies indicate they may help moderate rises in blood sugar after eating by inhibiting enzymes that break down carbs.
In trials, guava leaf preparations reduced postprandial glucose elevations and supported better lipid profiles. Animal and human research points to improved insulin sensitivity and antioxidant protection for overall metabolic function.
