The composition, beneficial properties and contraindications of guarana

Guarana is an evergreen climbing vines, a member of the genus Sapindidae. It begins to bear fruit three years after "birth".

What is guarana

In science, it is known as "Paullinia cupana", one of the varieties of the plant that grows in the valleys of the Amazon. It is valued because of its fruiting seeds, counted among the soap berries, a close relative of the litchi, longan and aki.

The benefits and harms of guarana

The history of the exotic fruit began with a legend of the Indian peoples, Tupi and Guarani, according to which a long time ago in a small village there lived a baby. The baby was loved by all the inhabitants of his settlement - from small to large. But an evil ruthless god killed the wonderful boy, who was friendly, helping the lonely old people and the homeless. The whole village population began to pine for him very much. To make the villagers happy and cheerful again, one of the generous gods planted the child's eyeballs in the forest and village, and after a while the guarana grew. This is how the locals explained the unusual appearance of the plant.

The grains contain caffeine in large quantities. Therefore, the name of the fruit can often be found in the composition of energy drinks as an additive. The tonic substance in the composition of the fruit not only increases energy levels, but also contributes to improving the skin and the loss of extra pounds.

To obtain the natural energy drink, the fruits with a pungent odor are used to extract the pulp and seeds, which are washed, dried, roasted if necessary and ground to a powdery consistency. The resulting mixture was used in ancient times by Amazonian tribes.

Bacteria, fungi, various pathogens due to the high percentage of pure caffeine are not afraid of the plant. The shrub can be compared to a weed in terms of vitality.

Brazilians have been using the fruit as food and medicine since the late 1950s. The production of the first drink based on it, launched by Luiz Barrett, started at the beginning of the twentieth century. Twenty years later, the sparkling wine "Antarctica" was invented, gaining recognition in many countries.

What it looks like

The shrub reaches 10-12 meters in height. It has large leaves and during flowering is studded with bunches of bright red inflorescences from which the bitterish fruits emerge. The latter are about the same size as coffee beans or grapes.

It is prized for its seed pods, which are about 7-8 cm long. They crack as they mature. The color palette of the capsules begins red and ends in brown. The black seed itself is located on a white seed pod. In appearance, if you look closely, the opened fruits resemble a human eye.

Where it grows

Guarana is also referred to as the Amazon chestnut, which is widely grown in South American countries. Since ancient times, it has been used as a means of payment by natives. The Tupi and Guaraní Indians took the fruit with them on their long and arduous journeys. During the latter, the enterprising participants obtained a powder from the seeds and treated wounds with it.

The plant is native to Brazil and Paraguay, located in the Amazon basin. Fruits are cultivated in Colombia, Peru, Venezuela. In all of these states, guarana has been cultivated for centuries. In Brazil, chestnut plantations are located in two sunny states: Bahia and Amazon.

Guarana begins to flower in early March, just as the rainy season ends. During the summer the fruits mature and are harvested by hand. The plant became widespread thanks to the German botanist Christian Paullini, who discovered it in the 18th century. Since then, the fruit has been used both to make drinks and to treat illnesses. But mentions of the plant are found both in 16th century writings by Oviedo, Cobo and Hernandez, and in treatises by Spanish chroniclers around the same time.

Composition and calories

It is known that of all the guarana shrub, people use only the seeds, ground into a powder. This mixture is then taken internally as a dietary supplement or added to cosmetic products. The caloric value per 100 grams is 25-26 and the GI ratio is 0.1/0/6.5, respectively. Compounds have been found in the composition of the seeds:

  • theobromine;
  • guaranine;
  • tannins;
  • zinc;
  • polyphenols;
  • magnesium;
  • sodium;
  • essential oils;
  • manganese;
  • antioxidants;
  • vitamins A, E, B and PP;
  • Theophylline;
  • amides;
  • xanthine alkaloids.

The action of the fruit of the Amazon chestnut has been compared to coffee, but it is longer in duration from the fruit kernels and has an effect on the stomach. If you need to mobilize your energy, guarana is an excellent way to concentrate on the task and get a boost of energy.

Guarana molecules are similar in composition to caffeine, they are absorbed gradually and gently, and don't irritate the stomach walls, as compared to coffee beans. And the stimulating effect of the substance is much stronger than its analogues - it lasts about 6-7 hours - and not only provides the maximum burst of energy, but also fights with excess weight.

Epicatechin and catechin belong to the group of powerful antioxidants, protect the vascular walls and the heart muscle from the damaging effects of free radicals, and effectively fight signs of aging.

Vitamins A, E, B and PP are otherwise called "beauty substances", they are necessary for the human body every day. Minerals, which include compounds of calcium, iron, phosphorus, potassium and magnesium, perform functions related to metabolic processes, which is important in the transition to a balanced diet.

The presence of tannic acids, which have mild antiseptic properties, allows you to stimulate both the brain and the nervous system.

General benefits

Guarana seeds can have a stimulating effect that is about 5 times stronger than that of natural coffee beans. But at the same time, there is no overexcitation and palpitations.

Useful properties of guarana

Specialists do not recommend guarana as a dietary supplement, so it should not be used as an independent medicine. But Brazilian hunters have long used the fruit of the plant in the preparation of medicines. Some recipes have survived to this day:

  • For severe emotional distress;
  • frequent spasms and cramps all over the body;
  • weight loss or gain of muscle mass;
  • digestive problems;
  • poor memory and cognitive problems;
  • sexual dysfunction;
  • headaches and migraines;
  • a desire to increase stamina and strengthen the immune system;
  • a desire to improve heart function and lower cholesterol;
  • Severe hangovers.

Traditionally, guarana powder was used for high fevers, fevers, as a powerful aphrodisiac and as a prophylactic against infections. The Indians of Latin America were convinced that the fruit would cure hunger, fatigue, arthritis and stomach upsets. The indigenous peoples of the Amazon valleys attribute lifting functions to the plant, which is why they call it the fruit of youth.

The exotic fruit is a natural source of energy. Guaranín, a substance obtained from plant fruits, is as close as possible to caffeine in its chemical characteristics. After it enters the body, a strong "shaking" of the brain cells and stimulation of nerve endings takes place. This gives you an almost instant rush of energy and motivation to work.

It's important to know that the guarana seeds do not contain a very aggressive form of caffeine, but this only increases its stimulating effects. This kind of substance penetrates the cells gradually, but leads to overstimulation and addiction.

Guarana has a multitude of beneficial properties.

  1. Increased brain "strength." Studies have found that eating guarana seeds affects memory. One of the experiments proved the positive effect of low doses of the exotic product on memory and attention.

  2. High content of antioxidants. The benefits and harms of the fruit are due to certain components. The fruit contains a fairly large number of antioxidants, which can include molecules of caffeine, tannins, saponin, theobromine and catechin. Antioxidants are useful because they actively fight free radicals, preventing the formation of new ones and the progression of harmful oxidative damage to cells. Some studies have shown that antioxidants even protect against cardiovascular disease, cancer, diabetes, and other chronic ailments.
  3. Preventing fatigue. Guarana fruit loaded with 6% caffeine has an effect on certain brain neurotransmitters, due to which the energy level rises and a burst of energy occurs. That is why coffee and energy drinks are used by humans to quickly regain energy after a hard day's work or emotional turmoil. One scientific study stated that the fruit reduces mental fatigue.
  4. Improved intestinal peristalsis. As far back as the Amazonian tribes, guarana was used as an effective natural remedy for GI disorders - diarrhea or constipation. The fruit helps soothe intestinal problems. Caffeine aids in the proper digestion of food and its proper movement through the GI tract. Stimulating the digestive tract prevents constipation. The tannin in guarana prevents the elimination of excess fluid from the body - this helps to relieve the symptoms of diarrhea faster.

Also, cholesterol oxidation and progression of atherosclerosis is reduced - the formation of arterial plaques with regular use of fruits does not happen.

The former protects the skin from harmful UV rays, which slows down the photo-aging process and visibly increases blood circulation. Cosmetic aids with guarana extract reduce sagging of tissues and minimize wrinkles around eyes.
