These compounds help combat oxidative stress, which is linked to various chronic conditions.

It Has Antioxidant Properties
Antioxidants likecatechinslook for harmful and unstable molecules (free radicals) in the body.

Free radicals damage cells and contribute to the development of chronic conditions.
Catechins in black tea neutralize free radicals to minimize damage.
Some research indicates that black tea prevents the formation of aging-relatedamyloidproteins.
Amyloid proteins affect cognitive function and contribute to cognitive decline.
One large meta-analysis observed a 29% reduction in the risk of all-causedementiawith regular tea drinking.
However, researchers did not differentiate between the different types of tea.
Black tea’santimicrobialproperties may prevent diarrhea.
Polyphenols in black tea may contribute to this reduced risk.
Black tea may block the absorption of carbohydrates by inhibiting the activity ofenzymesinvolved in breaking down carbohydrates.
Still, not all evidence shows the benefit of black tea in reducing blood sugar.
One meta-analysis observed no significant effects of black tea on blood sugar levels.
It May Benefit Heart Health
Population studies indicate that drinking more black tea may protect against heart disease.
It May Help Fight Dental Plaque
Cavities (dental caries) result fromplaqueaccumulation on the teeth.
Plaque is a biofilm produced from saliva and bacteria.
Cavities occur when large quantities of bacteria exist on teeth, causing tooth enamel to break down.
Theaflavins in black tea have antibacterial properties that damage bacterial cell membranes to fight dental plaque and reduce cavities.
Preliminary research in rats indicates that black teareduces the development of cavities.However, research in humans is less conclusive.
However, habitual black tea consumption did not prevent cavities.
Reaching 200 mg of L-theanine from black tea is likely unrealistic without supplementation.
Still, L-theanine in black tea may provide calming benefits.
Some research indicates that consuming caffeine and L-theanine togetherlike in black teamay result in mental alertnessanda feeling of calm.
Generally, caffeine and L-theanine have opposing effects.
However, when consumed together, particularly during stressful moments, these two compounds may counteract each other.
Regularly drinking black tea reduces markers of cell damage and inflammation.
Specifically, tea drinking is associated with lower levels ofc-reactive protein, an inflammatory marker.
Preliminary animal research shows a potential anti-wrinkle effect of black tea extract when applied directly to the skin.
Black tea extract reduced skin damage and improved anti-wrinkling processes in mice exposed to ultraviolet radiation.
Other research in mice observes increases in skin moisture and collagen with oral administration of black tea extract.
Despite the promise of black tea on animal skin health, additional research in humans is necessary.
Does Adding Milk Make My Tea Less Healthy?
It’s unclear whether adding milk affects the benefits of black tea.
Pour boiling water over one tea bag or 1 to 2 teaspoons of loose tea.
Pour the water when it starts to boil because overboiling can make the tea taste flat.
Steep the tea for three to five minutes.
Do not judge a teas readiness based on color.
Color develops more quickly than flavor.
Reduce the brew time for a milder tea flavor.
Conversely, increase the brew time for a more pungent taste and more components like theanine.
Black tea should be stored in a dark, cool place.
Teabags can be kept in the pantry for 18 to 36 months from purchase.
Loose-leaf tea maintains freshness for two years in the pantry and six to 12 months when opened.
Summary
Black tea is a popular, relatively safe beverage rich in polyphenols.
Incorporate black tea into your routine to reap its health benefits.
Aim for two to four cups per day, depending on other sources of caffeine you may consume.
