What is harmful grapefruit? What are the harmful properties of grapefruit?

Virtually any product is ambiguousinfluence on the human body. And what can you say if it comes to a hybrid? Here the problem is doubly complicated. It is impossible to simply add up negative and positive characteristics. A more thorough examination is required. Take, for example, grapefruit. It seems to be a common citrus fruit. Good, and only. But many are more interested in what grapefruit is harmful.

A bit of history

There was this unusual fruit somewhere in the middleXVIII century. It was first discovered in India and on the American continent. It is believed that it appeared as a result of crossing two citrus cultures: orange and pomelo. But no one can say this with complete certainty. At first it was called the "forbidden fruit." Then the fruit affectionately called the "little sheddok" because he looked very much like a pomelo. Its modern name grapefruit was obtained with the easy hand of merchants from Jamaica. They noticed that the fruits of it grow not one by one, but whole bunches, like grapes. In English, "grapes" sounds like "grape", hence the name of the new fruit. Since the beginning of the XIX century, it began to grow on an industrial scale. Trade quickly gained momentum. There were many who wanted to try unusual fruits. Scientists paid much attention to their research. Numerous experiments have been conducted to find out what is useful and what is harmful grapefruit.

Acids are worth worrying about

Chemists and biologists around the world comprehensivelyexamined a new plant, studied its structure, properties and chemical composition. The results confirmed the useful properties of the product. But the goal was to understand what grapefruit is harmful in order to advise to limit its consumption to people who are at risk.

According to unequivocal opinion of experts, the newcitrus fruit should not be included in your diet for people suffering from gastritis, ulcers, as well as those with increased acidity. To this list, one can also refer patients who have problems with duodenal work. Here the logic is simple. The product itself already has a high acid value, and getting it into the patient's body only aggravates the situation. That, in fact, what harm grapefruit. The juice of this product, getting into the digestive system, irritates the sensitive mucous membrane. This causes a painful sensation, and with repeated exposure may lead to the appearance of additional lesions.

Threatened cancer

There is another group of people who are worthto think about whether grapefruit is harmful. Those who have liver problems are at risk of getting oncological disease in addition. It was such publications that began to appear recently, although many scientists consider this opinion fundamentally wrong.

Why is there a risk? Firstly, it should be noted that grapefruit has a rather complex chemical composition. Therefore, the liver takes a long time to process it properly. Secondly, as is known, the development of tumors (malignant) is sometimes caused by an elevated content in the body of a hormone called estrogen. If the liver is not overloaded, then it has time to process it in time and withdraw the surplus along with the other harmful substances. Otherwise, it accumulates in the body and can lead to irreversible consequences. Then the answer to the question, whether grapefruit is harmful, is beyond doubt. For people with similar diseases or the threat of their occurrence - of course, yes. However, we repeat, this is just a hypothesis, which has not yet been scientifically supported by any reliable data.

Dangerous neighborhood

Scientists have found yet another answer to the question of how,why grapefruit is harmful. It is very important to know people who use these or other medications in their lives. The bottom line is that the grapefruit juice contains special enzymes that have a negative double effect on some medicines:

1) They can artificially increase the concentrationdrug, which results in its overdose. Such cases occur in the treatment of heart disease or kidney failure. Do not eat grapefruit for those who use antidepressants or tranquilizers, as well as various kinds of pain killers.

2) In some cases, enzymes interferenormal digestion and sequential splitting of the drug. In the end, it may not have the proper effect on the body. This happens, for example, with contraceptives. Grapefruit partially neutralizes them and reduces the desired result to zero. Women who try to prevent unnecessary pregnancy medication, must necessarily know this and never use it with tablets.

Healthy sleep

To look good, a person should normallyto have a good sleep. This rule has been known for a long time. A person who has rested can be seen from afar. He cheerfully looks and is confident in himself. He does not face a bad mood and lack of appetite. But not everyone can cope with a lack of sleep. There is an erroneous opinion that all fruits are good at any time of the day. This is a fundamentally wrong statement. For example, if a person, going to bed, drinks the next glass of appetizing grapefruit juice for sleep, then he will not fall asleep very soon. The question arises: "Why is grapefruit bad at bedtime?" The answer is simple. The juice of the fragrant tropical hybrid has a strong toning effect. Therefore, instead of a sound sleep, he will certainly give the body vivacity, not at all necessary at this time of day. And as a result - sleepless night and shattered nerves. This fact must necessarily be taken into account for those for whom the opportunity to fall asleep quickly and swiftly is an impossible desire, a peak that can not be achieved.

By advice of dentists

Studying grapefruit, the harmful properties in it were found anddentists. They noticed that the juice of this product contains a huge number of different acids. It would seem that a diverse composition should only benefit. But in fact everything was not so simple. When the saturated solution enters the oral cavity, the teeth fall first. Highly concentrated liquid corrodes a thin tooth enamel, creating in it cracks. In the lesions increases the likelihood of caries. It turns out that the juice is, as it were, a catalyst for the disease, which has to be treated for a long time in neglected cases. Sometimes the cracks are so significant that no efforts of specialists can not save the situation. The damaged tooth is almost unprotected from external influences. Equally unenviable fate awaits the gums.

Woman and grapefruit

All women want to be beautiful. But nature sometimes does it unfairly. And then the beautiful half of humanity takes matters into its own hands. In the course go sport and diet.

Women begin to torture themselves with specialexercise and exhausting the dietary restrictions. Some in the hope of quickly achieving the desired result simply starve, and a lack of vitamins try to make up for the fruit. Scientists have found that, for example, grapefruit leads to a decrease in appetite, which is important in the process of weight loss. Many enterprising ladies buy these fruits for future use and eat them without restriction, without thinking about the consequences. But in fact, is grapefruit harmful to women? In a word it is impossible to answer. So, scientists of America not so long ago conducted researches of influence of this tropical fruit on a female organism. It turned out that those who used it, were clearly predisposed to the development of breast cancer. But we can not say with certainty about this, since during the experiments all possible factors were not taken into account.

What threatens the beautiful ladies

Finding out what is harmful to grapefruit for women, you can notto overlook cosmetic preparations. Every woman uses different tonics, creams and balms every day. For more effective action in some of them add citrus oils. In particular, grapefruit oil is a part of many creams.

It seems that it's terrible here? The problem is that the presence of this component increases the sensitivity of the skin to the action of sunlight, which can lead to serious burns. Therefore, cosmetologists advise to use such creams at least two hours before going out. This time is enough for the drug to have the right action and absorb completely. Such recommendations are mandatory for execution. They should not be violated, so you do not have to spend time and money for additional treatment.
