Health benefits of tea – a natural cancer fighting and anti-aging agent

Health benefits of tea – a natural cancer fighting and anti-aging agent

  • Oct 05, 2016

Articles from the American Journal of Clinical Nutrition show that tea may indeed be a magical elixir, as it was shown to promote weight loss, prevent chronic illnesses and improve mood.
 "Humans have been drinking tea for some 5,000 years, dating back to the Paleolithic period," says Prof. Blumberg. "Modern research is providing the proof that there are real health benefits to gain from enjoying this ancient beverage."

Apart from containing the well known vitamin C and E antioxidants, tea also contains natural antioxidant chemicals – polyphenols and flavonoids – that help protect body from free radicals that contribute to the effects of aging and pollution.
Free radicals are unstable, highly reactive molecules. Though they occur naturally in body, they can also be formed in response to excess pollution, too much sunlight and exposure to cigarette smoke. Once formed, they attack other molecules in the body leading to cell damage and, more critically, often attacking the DNA itself within your cells. Some scientists believe that this type of free radical action has been implicated in certain chronic and ageing diseases such as cancer, heart disease, stroke, rheumatoid arthritis, cataracts and Alzheimer’s disease.
Antioxidants are chemicals that have a strong preference for neutralising these damaging free radicals.  So once a free radical forms in body, it will quickly react with antioxidants in blood and cells before it has a chance to damage cells or their DNA.
Tea leaves and buds have one of the highest total flavonoid contents of all plants at 15%.  These types of chemicals are also naturally found in many fruits and vegetables, which has led to the correct belief that a diet high in vegetables can reduce cancer risks.  However a typical cup of white or green tea has more flavonoid antioxidants than over 5 meal sized portions of fruit or vegetables!

Very Low Levels of Caffeine
Tea contains two to three times less caffeine than a typical cup of coffee.  While a typical cup of coffee contains around 130mg of caffeine, black teas are usually less than 50.  Green teas and White teas have much less than this, around 25mg!  This means a cup of white or green tea has only around 20% the amount of caffeine as a cup of coffee.  If you find drinking coffee makes you nervous, gives you a headache or the jitters, or just keeps you awake at night, tea – especially Green and White Teas – may be just what you need.

Reduces the Risk of Stroke and Heart Attack
Tea acts to both help reduce cholesterol levels and thin the blood.  These two actions lessen the chances of blood clots forming in veins and arteries, which are the cause of both heart attacks and strokes.  In Holland a study conducted over 10 years and 1,000 people found that people drinking 3 cups of black tea a day had a 50% reduced risk of fatal heart disease compared to non tea drinkers!
More recent results from clinical trials are indicating that chemicals in teas called flavonoids may prevent the formation of the so-called bad cholesterol in the blood.  This type of cholesterol is strongly tied to the build-up of plaque in artery walls.

Keep your Smile Full of White Teeth – Naturally
A great natural source of fluoride, which is added to water and toothpaste because it  strengthen tooth enamel, the outer covering on teeth that makes the white and prevents getting holes and cavities.  Apart from the benefit of the fluoride, teas have been shown to help prevent bacterial growth.  While bacteria are always naturally present in mouth, reducing their numbers helps reduce the formation of plaque on teeth – the stuff the dentist scrapes off when you visit them – and so is a natural way to further reduce your chance of getting holes and cavities.

Naturally Boost your Immune System
While not proven yet with rigorous scientific studies, initial research suggests that drinking 3 cups of tea daily will result in a higher level of activity from your immune system.  This will help body naturally fight off both viral and bacterial infections.
Help Body Stay Hydrated
As caffeine is a diuretic, caffeinated beverages, which includes tea, were previously thought to be drinks that didn't help body maintain its level of hydration.  But more recent studies have shown that unless you drink more than 10-15 cups of black tea – or 20-30 for green or white teas – the water in the tea is actually retained by the body.  So tea is now considered a great way to maintain body’s hydration levels, and so makes a great drink for hot summer days.

Calorie-free and Increased Metabolism
A cup of tea doesn't contain any calories.  So unless you're adding milk or sugar, tea makes the perfect, satisfying drink to help you reduce your weight.  Additionally green and white teas have been shown to naturally increase the body’s rate of metabolism, which helps body burn off a higher level of calories each day.
While exercise and food play a more dramatic role in helping reduce weight, tea – especially if used to replace coffee or sodas – can play a big part in weight loss, especially if put together with daily exercise and a balanced, low-fat and low-sugar diet.

Improves Bone Strength
Another benefit of the polyphenols in green tea includes improving bone quality and strength, particularly in the wake of osteoporosis. Tea drinking in one study was associated with a 30% reduced risk of hip fractures in men and women aged 50 years or older.

Alertness and Problem Solving
Researchers note that the amino acid theanine and caffeine in tea are thought to confer psychological benefits to drinkers, strengthening attention, mood and performance and facilitate better focus on tasks.
