Caffeine Showdown Coffee VS Tea

First and foremost, drinking coffee is tightly connected to insomnia, and we simply cannot imagine our life without a cup of coffee in the early morning. The first thing we make is a cup of strong coffee to keep you vigorous during the whole day long. This marvelous drink makes you smarter, better, faster and stronger. The same goes for tea. The science of hot drinks hides the unrevealed.  The question of the usefulness of tea and coffee for health bothers any person almost daily. As soon as we pour a steaming aromatic cup of coffee or brew some tea, the invisible controller inside of us asks the eternal question - is not it harmful to health? In general, what is more useful - tea or coffee? Let's try to understand these issues from the standpoint of modern dietology. 
Caffeine Showdown Coffee VS Tea
According to the dietology, tea and coffee are related to taste products. Drinks from tea and coffee have a taste, tonic, thirst and therapeutic value. They are part of the daily diet of people.

It should be noted that dry tea, grains and coffee powder contain all the main food substances. They have a lot of potassium, in coffee - vitamin PP, in tea - vitamin B2. However, the nutrients contained in that dry amount of tea and coffee, which is necessary for the preparation of drinks, play a very minor role in the daily diet. Significantly more important are the many biologically active components that makeup tea and coffee, in particular, caffeine, flavonoids, tannins.

Caffeine stimulates the accumulation of the macroergic compounds necessary for it to function properly in cells. This excites the central nervous system, stimulates the activity of the cardiovascular system (increases muscle contraction and increases rhythm, leads to increased blood pressure), increases heat production and urination, and increases the secretion of the stomach.

Everyone knows that coffee affects the body more than tea. The fact is that the caffeine of tea is associated with tannin and therefore its effect is weaker, but theophylline tea stimulates urination stronger than caffeine. However, the addition of milk and cream in tea or coffee softens the effect of caffeine.

Is it harmful to drink coffee and can it be part of a healthy diet? Let us discuss this issue.

1. It may be hard to say whether coffee is good or bad for you. The reception of strong coffee causes a short-term increase in blood pressure, which can worsen the condition of patients with essential hypertension. However, large-scale studies conducted in a number of developed countries have not revealed a direct relationship between the prevalence of hypertension and the intake of coffee.

2. Similarly, the relationship between coffee consumption and the development of malignant tumors has not been confirmed.

3. It should be noted that coffee grains contain a number of substances that have been found to promote the increase of cholesterol in the blood. People who are especially scrupulous about their health, in this regard, can advise the following: these compounds can be extracted with hot water and filtered through a paper filter.

4. The International Operational Group for the Prevention of IHD and the International Society of Atherosclerosis included not only tea but also coffee in the list of drinks recommended for ischemic heart disease. Although, soluble or filtered on the coffee machine.

5. In many developed countries, there were no differences in the overall mortality (from all causes) among few or not drinking coffee people and among its lovers, but without abuse more than 4 cups of coffee a day, if each contains at least 1 teaspoon of instant coffee).

When coffee is especially useful?
  1. Coffee can temporarily help some migraine sufferers during an attack of headaches.
  2. Arterial hypotension (people with low blood pressure).
  3. Chronic heart failure, depending on the rhythm of the heart.
  4. Asthenia (physical and neuropsychiatric weakness) after prolonged chronic diseases.
  5. Reduced secretory function of the stomach or motor function of the gallbladder.

When should you be careful?

1. Strong black coffee can adversely affect the diseases of the esophagus (reflux esophagitis), the stomach with increased secretion (gastritis, peptic ulcer).

2. With the increased motor function of the gallbladder.

3. With the increased emotional function of the intestine - irritable bowel syndrome.

If there are pains, heartburn, belching or other uncomfortable symptoms after drinking coffee, then it should be excluded from the diet. However, individual features are possible.

4. Strong coffee is not recommended for adverse reactions to it in patients with hypertension, Parkinson's disease, glaucoma, with increased heart rate (tachycardia), heart rhythm disturbances (arrhythmias).

5. You should not drink coffee in the afternoon if suffering from insomnia.

Let's talk about tea

Black or green tea is obtained depending on the method of treatment. It should be noted that green tea contains more substances inherent in the leaves of the tea bush. It is known that when brewing green tea about 45-50% of its substances remain in the infusion, while in black - 30-40%.

Useful properties of tea

1. Green tea quenches thirst better, however, there are more flavoring and aromatic substances, as well as caffeine available for the body in black tea.

2. Green tea helps to reduce swelling.

3. Tea catechins have an antioxidant effect, binding excess free radicals in the body, while the antioxidant capacity of green tea is 2.5 times higher than that of black tea.

5. Tea catechins are classified as anti-cancer factors for the development of certain oncological and cardiovascular diseases.

6. Strong tea contains a significant amount of theophylline, expanding the bronchi so it can be the first self-help tool to relieve faint bouts of bronchial asthma.

7. Strong tea, especially green, is useful for diarrhea, but it is not recommended if you suffer from constipation.

8. Strong tea is also useful in those painful conditions in which coffee is recommended, especially if the patient does not like coffee.

Modern Dietetics says that not strong tea can be drunk by almost all sick people, but there are restrictions in the consumption of strong tea:

1. Tannins of tea bind to iron so that strong tea during and after meals should be limited in the diet of patients with iron deficiency anemia.

2. Strong tea should not be consumed together with iron preparations or multivitamin-mineral preparations.

3. There are restrictions for strong tea, which are of an individual nature: increased excitability, insomnia, tachycardia, deterioration of well-being in arterial hypertension.

The therapeutic diet includes various fruit and berry and herbal teas. For example, with raspberries and lime flowers - for colds, with rose hips and corn stigmas - for diseases of the gallbladder.

You can drink coffee drinks (coffee-surrogate) as well, which are reminiscent of the taste of coffee but not containing caffeine. They are prepared from fried and ground barley, oats, rye, chicory, chestnuts, soy, acorns, dog rose. At the same time, the nutritional value of many coffee drinks is higher than that of natural coffee. Manufacturers add from 5 to 35% of natural coffee in coffee drinks, while other coffee drinks do not contain it at all.
