Answer:

Matcha, a finely ground powder made from green tea leaves, originates from Japan. This vibrant green powder, with its distinctive flavor, is used in various foods and drinks. Matcha latte, a blend of matcha and milk, often replaces coffee, especially for those who enjoy green tea or want to reduce caffeine intake.

Matcha latte contains L-theanine, an amino acid that promotes relaxation, and catechins (like EGCG) with antioxidant properties that support cardiovascular health and fat metabolism. A typical 200 ml matcha latte (using 2 g of matcha powder) contains approximately 60-70 mg of caffeine, though this can vary based on the amount of matcha and preparation method.

Breastfeeding mothers are generally advised to consume no more than 200 mg of caffeine daily (equivalent to 2-3 diluted matcha lattes or 1-2 small cups of coffee). Caffeine levels peak in a mother's bloodstream 1-2 hours after consumption and can linger for several hours. Infants, especially those under 6 months, metabolize caffeine slowly, making them susceptible to sleep disturbances, irritability, or reduced feeding if the mother consumes too much. Excessive caffeine can also cause insomnia, rapid heartbeat, and anxiety in mothers, especially those sensitive to it.

Breastfeeding women should limit their caffeine intake to about one serving per day, ensuring total caffeine consumption from all sources, including coffee, chocolate, and soda, does not exceed 200 mg. Drink matcha after breastfeeding, at least 2-3 hours before the next feeding, to minimize the caffeine transferred to the milk. Monitor your baby for any sleep difficulties or increased fussiness after you consume matcha. Choose high-quality matcha, drink it in the morning, and dilute it to reduce caffeine concentration.
