The middle child of the true teas, sitting between green and black in oxidation. It carries both catechins and the theaflavins of darker tea, and is most studied for metabolism and blood sugar.
Oolong is the tea ordered at the dim-sum table and the one quietly recommended in weight-loss circles. For Black Americans managing the metabolic cluster, it is an unsweetened, zero-calorie alternative to the soda and sweet tea that drive the same conditions.
Oolong's partial oxidation gives it both green-tea catechins and the larger theaflavin polyphenols of black tea. Controlled feeding studies show oolong raises energy expenditure and fat oxidation modestly and improves post-meal blood glucose, which is why it carries a metabolism and weight-management reputation. Its polyphenols inhibit pancreatic lipase, blunting fat absorption. For the Black American with metabolic syndrome — the cluster of high blood pressure, high sugar, and central weight — oolong is a low-calorie tool that nudges several levers at once.
Use water around 185-200°F depending on the roast — lighter oolongs want cooler water, darker roasts can take near-boiling. Steep 3-5 minutes. Oolong is famously re-steepable; a good leaf gives five or more infusions, each one different.
