The world of tea

TEA, HEALTH AND WELLBEING

Tea is fashionable worldwide for its healthy properties. Thus, there are more and more studies on the beneficial effects of the components of this plant on health, provided this infusion is included in the normal diet.

In particular, we highlight the following properties:

  • Tea polyphenols are antioxidants that protect the body against cellular aging, helping to regulate cholesterol levels and helping the body absorb less fat.
  • Its fluorine content prevents tooth decay.
  • Theophylline exerts a diuretic and vasodilator effect.
  • Theine is a ""mild stimulant"" of the central nervous system that helps clear the mind.

THE ANTIOXIDANTS OF TEA

Various studies carried out in laboratories in different countries have found substances in tea that have traditionally shown their effectiveness in the prevention, control and reduction of some types of cancer or cancerous tumours.
Despite the caution of the researchers, the findings of several experiments carried out seem to support the theory that flavonoids, organic compounds found in tea with antioxidant properties, exert an inhibitory action over this disease in some cases.

The temperature at which the infusion is ingested may also tilt the balance one way or another. The antioxidant properties of flavonoids tend to disappear when the tea is consumed hot. Research in China in 1994 showed that in cancer of the oesophagus, in the prevention of which tea plays an important role, this relationship could be found. Thus, the positive effects of tea decreased as the temperature at which it was consumed increased.

The antioxidant properties of flavonoids also impinge on the most important organ of our body: the heart.

Research so far has established a link between the consumption of 4 or 5 cups of tea a day and decreased blood cholesterol and blood pressure regulation.

TEA CONTRIBUTES TO CARDIOVASCULAR HEALTH

Tea has shown its effectiveness in reducing cholesterol and triglycerides (two types of fat in the blood) as shown by some studies carried out in Britain and Norway:

  • In the first experiment, whose results were published in 1992, 4,317 men and 1,698 women showed evident signs that as tea intake increased blood cholesterol levels decreased.
  • In the same year 9,856 Norwegian men and 10,233 Norwegian women aged from 35 to 49 years underwent an identical study also demonstrating a significant decrease in cholesterol. The influence of tea on blood pressure has also been analysed, finding that the consumption of 4 to 5 cups a day is able to reduce the maximum or systolic value thereof.

Its low sodium content and the presence of potassium, both of which are traditionally associated with blood pressure control, explain the regulatory role of the infusion (2 other studies among large groups of people seem to support the thesis that the regular consumption of tea reduces the risk of cardiovascular events).

The action of flavonoids, verified in a number of laboratory experiments, would be responsible for this beneficial effect. However, as in the case of the tests carried out to determine the positive effect of tea on cancer prevention, there are difficulties in isolating the role of the drink from the whole of the diet followed by the people tested. It is known, however, that the human body needs flavonoids for their antioxidant properties and that tea is, in many countries, the main source of supply of this important organic compound.

Nose Phase

Nose Phase

Always smell it for a while before touching it with your lips. It is essential to bring the nose to the surface and learn to spin the cup briefly but effectively so that the movement of the liquid causes the evaporation of its aromatic elements.

These are subdivided into a collection of 'series' which experience and tasting with experts will help you master.

According to classical guidelines, the aromas are subdivided into these series:

 

  • animal (leather, butter, …)
  • floral (orchid, rose, jasmine, …)
  • woodland (undergrowth, damp earth, mushroom, ...)
  • vegetable (vegetables, asparagus, spinach, peas, ...)
  • herbal (grass, hay, fresh plants, ...)
  • fruit (apple, grape, peach, berries, exotic fruits, ...)
  • balsamic (eucalyptus, liquorice, ...)
  • wood (sandalwood, cedar, pine, resin, ...)
  • spicy (pepper, cinnamon, ...)
  • roasted (tobacco, caramel, cocoa, roasted, ...)
  • marine (seawater, seaweed, iodine, ...)
Palate phase

Palate Phase

The taste depends on the stimulation of our so called ""taste buds"", which are situated preferably on our tongue, though some are situated on the palate; its sensitivity is variable.

Nerves (mainly facial) connected with the taste buds transmit impulses to the nerve centre located in the medulla (continuation of the marrow where the spine begins); from here, the impulses are transmitted to the upper and inner faces of the parietal lobe, closely related to the area of the brain associated with smell.

The nearly 10,000 taste buds that humans have are unevenly distributed over the upper side of the tongue, where they form spots sensitive to certain classes of chemical compounds that induce the sensations of taste. Generally speaking, the taste buds sensitive to sweet and salty flavours are concentrated at the tip of the tongue, those sensitive to acidity at the sides and those sensitive to bitterness at the back.

Food chemicals are dissolved in the moisture in the mouth and penetrate the taste buds through the pores in the surface of the tongue, where they come into contact with sensory cells. When a receptor is stimulated by one of the dissolved substances, it sends nerve impulses to the brain. The repeat frequency of the impulses indicates the intensity of the flavour.

What we commonly call ""taste"" is actually the ""flavour"", which results from the interaction of the senses of taste and smell. Other sensations we get from food, the pungent taste of a strong mint or the fizz of sparkling drinks, as well as the texture, temperature and presentation, are also part of the taste experience.

80% of what we perceive as taste is actually smell. Humans are able to distinguish about 20,000 different smells, each with 10 or more different degrees of intensity. The sense of smell is activated when smells reach the olfactory receptors in the nasal cavity via two pathways: inhalation through the nostrils and through the inner part of the mouth, when chewing and swallowing.

Visual Phase

Visual Phase

Note the clarity and colour (intensity, hue, transparency). The appearance of the tea tells you much about it; its colour is the first contact, and its appearance should invite us to drink it. The colour intensity gives a more accurate picture of the body of the tea and its tannic structure. If the colour is strong, deep and concentrated, there is every chance that the tea is also strong and rich in tannic substances; on the other hand, if the colour is weak, the tea will probably have a light body and be shorter on the palate, which in no way rules out that it can be pleasant, rich, flawless and a perfect example of a specific typology.

Colour has many nuances that indicate the degree of oxidation of the tea or speak of production processes. The yellow-green colour of Japanese green teas is a result of their steaming process. However, Chinese greens that have undergone roasting acquire coppery shades and we talk about old gold, copper or pale yellow.

Limpidity measures the presence of suspended particles in a tea. Not to be confused with turbidity, this is a result of poor preservation, or of using old and broken leaves. If we analyse limpidity we determine whether a tea is bright, clean, transparent, matte, opaque, dirty, dull, cloudy, etc. Limpidity, transparency and brilliance are suitable qualities for white teas, green teas and oolongs. In the case of black and red teas we can find limpid teas that are not excessively transparent, because transparency depends on the intensity of their colour.
