Researchers at Friedrich Schiller University in Germany have found that eating two grapefruits a day reduces bleeding gums and the risk of developing inflammatory processes in the oral cavity.
The results were obtained based on the study, which involved 58 people with chronic gum disease - smokers and non-smokers. The researchers observed samples of the gum tissue of the volunteers under a microscope.
They found that in smokers, the tissues in the oral cavity were severely damaged - collagen and other structural components of this tissue were in a state of anxiety.
Experts are adamant that smoking increases the likelihood of developing diseases of the oral cavity as it reduces the level of vitamin C in the body.
Among smokers, the level of vitamin C is on average 29% lower than in others. This fact is probably due to the influence of vitamin metabolism. With nicotine.
After the study participants received 70 mg of vitamin C daily for six weeks, the condition of the tissues visibly changed and the surface of the gums was smoothed. It was found that with daily consumption of grapefruit, the level of vitamin. C in the blood increased in both groups - smokers and non-smokers. In smokers, however, the level of vit. With the rest lower compared to the group of non-smokers.
A study by German scientists confirms that a sufficient content of vitamin C in the body is a good prevention against gingivitis. That is why it is important to consume fruits rich in vitamins daily. C.
Eat one grapefruit a day - this significantly reduces cholesterol levels and as a consequence the risk of cardiovascular disease. Such advice is given by Israeli scientists from the University of Jerusalem.
The conclusion is based on a study of a group of patients who underwent heart surgery. These men and women had high levels of cholesterol and lipids, which is why their bodies did not respond adequately to medications used to heal wounds.
Patients were divided into three groups. Those in the first group ate one red grapefruit a day, the second group ate one yellow grapefruit a day, and the third group was not given grapefruits at all. The experiment lasted 30 days.
The results showed that in patients receiving grapefruit, lipid and cholesterol levels were significantly reduced, while in others no changes were observed. The other finding was that red grapefruit proved to be more effective, which scientists explain with the higher amount of antioxidants.
Of all the fruit juices available on the market, it turns out that pink grapefruit has the highest nutritional value per unit of calories.
Studies conducted at the University of Florida show that the juice of the fruit is not only high in vitamin C, but it is greater than that of the juice of orange, pineapple, apple, and even white grapefruit. In addition to vitamin C, there is a large amount of potassium, magnesium, folic acid, thiamine. Pink grapefruit also supplies carotenoids - a source for the synthesis of vitamin A. One of them is lycopene, which gives the characteristic color of the fruit.
The nutritional density of grapefruit was examined by 100% juice. It represents the amount of nutrients per unit of calories. Nutrients include proteins, fats, carbohydrates, vitamins, minerals and more.
Citrus fruits are considered to be products with high nutritional density due to their particularly high content of nutrients, as well as low caloric content. This is even more true for pink grapefruit. Even just one glass of 100% juice provides the full daily need for vitamin C.
According to a clinical study, drinking fruit juices should be avoided when taking anticancer drugs, hypertension drugs atenolol, celiprolol and talinodol, cyclosporine, which suppresses transplant rejection, and certain antibiotics such as ciprofloxacin, levofloxacin and iv. It has been shown that many juices can alter the pharmacological activity of drugs and consequently suppress or enhance their action.
A few years ago, grapefruit juice was found to increase the absorption of certain drugs and make them toxic. The clinical trial was performed in healthy volunteers who took the anti-allergic drug fexofenadine with grapefruit juice or water.
When the drug is drunk with water, it is completely absorbed, and when drunk with juice - half. The active substance in grapefruit, called naringin, suppresses a key factor that governs the body's absorption of these drugs.
On the other hand, grapefruit juice blocks the enzyme CYP3A4 in cholesterol-lowering drugs, making them potentially poisonous. The enzyme normally processes these drugs in the body.
Twenty years ago, Dr. Bailey found that consumption of grapefruit juice or the fruit itself increased the effects of the anti-hypertensive drug felodipine.
Juice from other fruits such as orange and apple can reduce the absorption of some drugs, affecting their effect, warn Canadian scientists. Among the medications used are used heart failure (beta-blockers), organ transplantation (cyclosporine), infections (quinolones) and others. David Bailey, a professor of clinical pharmacology at the University of Western Ontario, also announced years ago the role of grapefruit juice in improving the absorption of certain medications, which would lead to intoxication.
