Lately more and more on the real health benefits of consuming coffee, but they must be weighed against the possible negative effects, especially at higher doses. The ideal "fix" is always difficult to determine because people's perceptions of "a cup of coffee" vary widely, as the size of coffee cups. But the good news is that many of the benefits associated with 2 to 4 cups a day "and that's what most Americans drink anyway," said Joe Vinson, Ph.D.. Here are some interesting findings:
Coffee is good for the brain
Between 1 and 5 cups of coffee a day can reduce the risk of dementia and Alzheimer's disease and Parkinson's disease. How? Antioxidants in coffee can prevent some damage to brain cells and stimulate neurotransmitters involved in cognitive function. Preliminary studies have indicated that increasing the intake of coffee (or tea), the incidence of glioma, a type of brain cancer, tend to decrease. Some researchers speculate that these compounds in activated DNA repairing protein in cells, possibly preventing DNA damage that can lead to the formation of cancerous cells.
Coffee beat diabetes
Studies link frequent coffee consumption (four or more cups per day), with a lower risk of developing type 2 diabetes. Scientists suspect that antioxidant compounds in hlorogenichnata acid may increase the sensitivity of cells to insulin, which helps regulate blood sugar. While most of the studies did not report whether the coffee is made with caffeine, decaffeinated coffee could be even better, since other studies have found that caffeine leads to a blunting of insulin sensitivity.
Coffee has heart benefits
Some studies have shown that consuming one to three cups of coffee per day less a stroke than non coffee drinkers. Antioxidants in coffee extinguish harmful inflammatory effects on arteries. Researchers speculate that the compounds could increase the activation of nitric oxide, a substance that dilates blood vessels and lowers blood pressure.
Coffee care for liver
Research in the field is limited, but it appears that the more coffee people drink, the lower is the incidence of cirrhosis and other liver diseases. In an analysis of nine studies found that an increase of 2 cups of coffee daily intake is associated with a 43 percent lower risk of liver cancer. Possible explanation: antioxidants and caffeine and caffeic acid can prevent liver inflammation and inhibit cancer cells.
Coffee causes irritations
Sensitive to caffeine may experience irritability and anxiety at high doses. The chemical composition of caffeine resembles adenosine - a chemical associated with sleep and dispensing vessels. Caffeine binds to adenosine receptors and prevents its absorption, for which the activity of nerve cells increases, blood vessels constrict and get a refreshing or welcome side effect.
Coffee may contain cholesterol
Unfiltered coffee contains a compound that can increase levels of LDL (bad) cholesterol. Drink filtered coffee.
Home of the yellow fruit is southeast Asia. From there it was brought in tropical parts of Africa, and later in America. Besides delicious banana hiding of properties beneficial to health and well being.
1. Energy
Southern fruit is rich in simple carbohydrates that are broken down very quickly by our body. Thus our body is procuring high energy charge. This makes bananas suitable food for athletes and people suffering from fatigue and loss of strength.
2. In a good mood
Contained vitamin B6 in bananas stimulates the action of serotonin - "Hormone of happiness". It has beneficial effects on the central nervous system: improves mood and helps fight stress. Note that the initial amount in the southern fruit growing in the ripening process, but if the bananas brown spots appear, vitamin begins to degrade.
3. For the brain, heart and blood pressure
Thanks potassium, which contain bananas may significantly reduce the risk of stroke. To do so, taking a banana a day. Potassium also prevents cardiovascular problems and lowers blood pressure - you regularly eat three bananas a day. A helper is potassium magnesium that strengthens the heart and muscles. The level of both is not affected by the stage of ripeness of the bananas.
4. For slim figure
Furthermore, they contain almost zero fat grams, bananas are rich and specialty. complex carbohydrates. The body needs more time to their degradation and thus maintain a feeling of fullness in you long.If starvation diet, you can even eat six bananas a day. But it is important to drink at least three liters and mineral water or unsweetened tea per day. Otherwise bananas may lead to constipation. Keep in mind that the more mature banana is, the more complex carbohydrates are converted into simple, overripe bananas put on weight, not shoot them down.
5. For stomach problems
Taking three bananas a day in combination with three large glasses of mineral water or unsweetened tea to each of them regulate your digestion. In addition, some of the substances found in bananas, helps the formation of a protective layer type who "dress" the wall of your stomach and neutralize excess acids.
6. Against gallstones
Southern fruit pectin associated with excess bile acids in the body and dispose of it as it reduces the risk of developing gallstones. As a result, our body must re-formed bile, which requires cholesterol. And our body it comes from your blood and reduce the level there.
7. For premenstrual syndrome
Many women suffer from back pain in the the groin, nervousness and irritability before menstruation. Complaints are compounded by stress and lack of vitamin B6. In the case of banana helps with stiff muscles in the back and stomach area, and against the stretched nerves, and against the feeling of heaviness in the chest. Our advice: 4-5 days before the beginning of the cycle to start eating a couple of bananas a day.
It turns out that this part of the brain responsible for memory, significantly intensified its work, if one accepts regular products rich in choline (vitamin B4). Experiment in which they were involved around 1,500 people aged 36 to 83 years, has conclusively shown that a diet high in choline effectively contribute to the development and improvement of memory.
After 5 years of research has been confirmed: the more the level of choline in the blood, the more good memory, but also improves the abstract and spatial thinking. Also taking more choline leads to reduced risk of insulin and dementia, which is characterized by increasing age.
Diets that recommend scientists is to take such products as: chicken, milk, eggs and sea fish. Eggs and poultry meat can dadat additional forces of human memory, the researchers found.
Saturated with choline (vitamin B4) food protects the brain from aging. Brain less susceptible to dementia. This finding provides further evidence that the aging brain is emphasized human diet. Experts recommend that women take 550 mg of choline per day, while women - 425 mg.
