Puerh-Tea-And-Metabolic- Syndrome

Tea and Metabolic Syndrome

There is a growing body of evidence to suggest the beneficial effects of tea for regulating and preventing metabolic syndrome (MS or MetSyn).

Metabolic syndrome is the medical term for a combination of diabetes, high blood pressure and obesity. It puts patients at greater risk of heart disease, stroke and other conditions affecting the blood vessels.

On their own diabetes, high blood pressure and obesity can potentially damage blood vessels, but having all three together is particularly dangerous.

All three are very common conditions with up to 1 in 4 of the UK population currently estimated to be suffering from metabolic syndrome.


Symptoms of Metabolic Syndrome

  • Central obesity - a waist circumference of 37 inches or more (men) 31.5 inches or more (women)

  • Hyperlipidemia -  higher levels of triglycerides and low levels of HDL ("good" cholesterol) in the blood which can lead to artherosclerosis (blocking of arteries with cholesterol)

  • Hypertension - high blood pressure consistently 140/90mmHg or above

  • Insulin Resistance - difficulty controlling blood sugar levels

  • Higher risk of Deep Vein Thrombosis (DVT) - an increased risk of developing blood clots

  • Inflammation - a tendency to develop inflammation (swelling and irritation of tissues)

  • PCOS - Polycystic Ovarian Syndrome in women is recognised as a secondary syndrome of MS


Tea and Metabolic Syndrome Research

The beneficial effects of tea in the prevention and management of metabolic syndrome has been the focus of recent research. Some studies suggest a relationship between the active ingredients in puerh tea and the following benefits for patients with metabolic syndrome: 

  • Reduced fats in the blood stream - Puerh tea was found to lower levels of fats (tryglycerides and cholesterol) in the blood stream. 

  • Increase in good cholesterol - Puerh tea increased levels of HDL-C (‘good’ cholesterol) and lowered levels of LDL-C (‘bad’ cholesterol)

  • Reduced weight gain - Puerh tea reduced development of fat deposits between viscera (liver) and the skin (adipose layer) leading to lower weight gain (growth suppression)

  • Blood sugar regulation - Puerh tea helped to regulate blood sugar levels after eating

  • Weight loss in obesity - Polyphenols in puerh tea (epigallocatechin-3-gallate - EGCG) helped to increase fat oxidation (the break down of fat stores) in a group of obese men in a US study.

Dosages and specific effects of individual plant chemicals in Puerh tea are still being researched but studies have been encouraging.

What is Puerh Tea?

At Elixir we have two Puerh Teas. Our Raw Puerh is called ‘Yunnan Peak' and our Cooked Puerh is called ‘Hidden Amber’. 

Puerh tea is a compressed, aged, post-fermented tea that is made from varietals of Camelia sinensis assamica.  Puerh is grown and processed in Yunnan, Southern China. 

Puerh tea leaves are processed into two main types of tea: Raw or Sheng Puerh and Cooked or Shou Puerh.
