8 Health Benefits of Oolong Tea

It contains many vitamins and minerals

Some of the main antioxidants in oolong tea, known as tea polyphenols, are 

• theaflavins, thearubigins & Epigallocatechin gallate (EGCG). 

Oolong tea also contains theanine, an amino acid responsible for the tea’s relaxing effect.

The polyphenol antioxidants may help maintain normal blood sugar levels & decrease the risk of developing type 2 diabetes. 

Some studies includes :

• drinking 24 oz (720 ml) of oolong tea per day had a 16% lower risk of developing type 2 diabetes

• consuming 50 oz (1.5 liters) per day had up to 30% lower blood sugar levels at the end of a 30-day study

However, the evidence is mixed and more research is needed

Help decrease the risk of heart disease, stroke and high blood pressure in some people.

Some studies includes :

• 76,000 Japanese adults observed that who drank 8 oz (240 ml) or more per day had a 61% lower heart disease risk

• regularly consuming 4 oz (120 ml) of green or oolong tea per day may reduce your risk of developing high blood pressure by up to 46%

Tea contains caffeine, may slightly raise blood pressure, this effect tends to fade with regular caffeine consumption

.

The combination of caffeine and polyphenols found in oolong tea may help increase the amount of calories and fat burned each day. This could ultimately help speed up weight loss..

• increased the amount of calories burned by about 4.8%, but only the tea polyphenol and caffeine mix increased the participants’ fat burning ability

Some participants responded better than others, so the effects likely vary from person to person.

The caffeine, antioxidant & theanine content of teas have beneficial effects on brain function and mood.

Some studies of tea includes :

• Tea containing both caffeine and theanine increased alertness and attention within the first 1–2 hours after consumption

• Tea polyphenols are also thought to have a calming effect, especially starting two hours after intake 

This effect was particularly strong for regular black and oolong tea drinkers

Similar to green and black tea, oolong tea may have protective effects against cancer.

Some studies of tea includes :

• Tea polyphenols might also decrease the rate of cancer cell division

• Protective effects for lung, esophageal, pancreatic, liver and colorectal cancers

Oolong tea falls midway between green and black tea, similar benefits may be expected. However, more research is needed on oolong tea specifically.
