Grapefruit: is harmful or useful?
You will be surprised, but the uniqueness of this fruit is,That no one really knows anything about him. It is believed that it appeared as a result of crossing pomelo and orange. And not one of its unique properties has not received reliable confirmation. Therefore, one can assume that this citrus has an antifungal, antibacterial and fat burning effect, and also lowers the level of cholesterol in the blood, improves the metabolism of sugar-containing substances, and so on.
Grapefruit and women
A couple of years ago in some media publications wereFrightening headlines that grapefruit can cause breast cancer. Fortunately, this assumption was false. Although ... A group of American scientists dealt with this issue and studied the health of more than 50 thousand women. As a result, scientists came to the conclusion that those women who every day ate a quarter of a grapefruit, more often fell ill with breast cancer, in contrast to those who did not eat this product.
But in such a statement it is necessary to take into account a number ofOther factors, which could provoke an oncological disease. First, it is worth considering that this conclusion was made on the basis of the study of those women who were in postmenopausal women. Secondly, solar radiation, the presence (absence) of abortions and other gynecological diseases were not taken into account. Plus, the use of grapefruit, but also the liver, affects the exchange of estrogens. For example, if there is hepatic insufficiency, then the grapefruit should be discarded altogether.
In general, the direct relationship between the use of grapefruit and oncology is still to be proved, but nevertheless, care must be taken.
Grapefruit and Drugs
But the following statement that the grapefruit is notCompatible with many medications, is fully proven. For example, grapefruit can not be used by anyone who takes birth control pills, otherwise one day you may find that you become a mother. And those who take antidepressants may notice an excessive depressiveness.
On the possible negative effect of the combinationSome drugs and grapefruit juice was published in the article by Kelly Morris in 1997. Three years later, American scientists confirmed this. It turned out that together with grapefruit, cardiovascular drugs can not be taken (their concentration increases), hypolipidemic drugs (a lethal outcome is possible). There was even a case when a man after a few months of drinking grapefruit juice fell into a hospital with acute hepatic insufficiency. Prior to this, doctors treated him for ischemic heart disease and atherosclerosis.
In 2006, scientists seriously worried about harm,Which can cause grapefruit health. A group of scientists from North Carolina began to fully study the grapefruit - along and across. As a result, they managed to calculate the "pest". They found the substance furanocoumarin. This substance slows the work of the cytochrome system. While the liver is engaged in disassembling the ingredients of grapefruit, drugs are carried throughout the body, and their concentration in the blood increases and reaches a dangerous level. After that, all side effects begin to appear. For example, during the study of the interaction of one of the drugs that reduces blood pressure with grapefruit juice, it was found that the concentration of drugs in the blood increased to 230%! Such a dose can simply lead to a catabolic outcome.
To date, the situation is so serious that some drugs are even tested for compatibility with grapefruit juice. It is worth noting that no other one gives such a reaction.
Grapefruit and muxing
After such an article, many grapefruit loversSeriously think about how to abandon this citrus fruit. Is it worth it? No, of course. But caution in any case will not hurt. Do not slyshikavlekatsya eating grapefruit and juice from them, especially if you take the medicine.
Some people use a grapefruit diet. When not recommended, eat citrus in the morning on an empty stomach and in small amounts. But this is not very useful for gums, teeth, stomach and mucous esophagus - too high acidity. Nutritionists are advised to consume one fruit a week or add a few lobules to a fruit or meat salad.
In small quantities, grapefruit is very usefulFor digestion. Pectins, organic acids, plant proteases, cellulose, orignan of rigid partitions accelerate the progress of food, activate the activity of the liver, promote the cleansing of the intestine, and also improve fat metabolism. But do not be sure that if you sit only on the grapefruit diet and do not do any physical exercises, then you will manage to lose weight.
And a note for women! It is necessary to undergo regular preventive examinations at the mammalogist. Because the constant postponing of visits to the doctor can do much worse than full cartrigeprifruits.
