A cup of fresh cocoa helps to improve brain function among older people, as some of recent studies claim.
In a rapidly changing and aging world more and more people suffer from age-related decline of intelligence or dementia.
Scientists are looking for more new methods to combat it, because this illness dramatically reduces the quality of life of the patient and often leads to the necessity of reconsidering the ways of living of all family members.
Flavonoids and antioxidants that are found in cocoa beans may be good sources of medicine in this situation.
Ian MacDonald, the scientist from Nottingham, United Kingdom, describes an experiment in which young women were drinking a cup of cocoa before performing complex tasks and performed them under control of a magnetic resonance imaging procedure.
The device showed a significant acceleration of cerebral blood flow in the group.
The next step was to study the impact of cocoa on the brains of people who have initially reduced cerebral blood flow.
According to the researchers, the benefits that cocoa brings were discovered during the investigation of health of the tribes of South America who drink this beverage in very large quantities.
However, the problem lies in the fact that cocoa powder which is delivered to the shops is poor with flavonoids. They are artificially extracted from raw materials, as flavonoids give this drink a bitter taste.
The researchers also fear that patients will “look” the same substance in chocolate that will lead to problems with obesity. Chocolate is food for pleasure and it will never improve health as opposed to cocoa in anticipation of bright future, scientists say.
According to Peter Piper, professor from Sheffield University, carbonated drinks contain a substance which harmful effects are still being underestimated.
Many of the problems that are associated with age-related changes or alcohol abuse, such as cirrhosis of the liver and Parkinson’s disease can be caused by usual soft drinks.
After spending a huge amount of time on experiments in his laboratory, Professor of Molecular Biology and Biotechnology, P. Piper came to the conclusion that sodium benzoate (E211), a widespread preservative in food industry being accepted by relevant authorities in different countries, can be very dangerous for your health.
Sodium benzoate has already been the subject of concern, but at that time it dealt with its carcinogenic effect.
The fact is that in conjunction with vitamin C in soft drinks, sodium benzoate produces benzene – a carcinogenic substance. There are even cases of withdrawing of some brands of drinks from the sale due to increased benzene content.
However, in general E211 is considered a safe additive, of course, with respect to current regulations at its maximum content in products.
Peter Piper has checked the effect of sodium benzoate on living yeast cells and found that this agent affects an important area of DNA in the mitochondria. He reported that these chemicals cause severe damage to DNA in the mitochondria and completely inactivate it.
Mitochondria give you energy and if you hurt them in large quantities, the cells start to malfunction. There are many diseases that are associated specifically with defect of this part of DNA: Parkinson’s disease and several neurodegenerative diseases; and yet it is associated with aging.
As a result of his experiments, the scientist proposes to revise standards of levels of E211 in food.
He believes that the existing methods for determining the damage from sodium benzoate are not quite true. Piper is particularly concerned of children who consume carbonated drinks in large quantities.
ScienceDaily (Jun. 17, 2008) — A new study has good news for coffee drinkers: Regular coffee drinking (up to 6 cups per day) is not associated with increased deaths in either men or women.
In fact, both caffeinated and decaffeinated coffee consumption is associated with a somewhat smaller rate of death from heart disease.
“Coffee consumption has been linked to various beneficial and detrimental health effects, but data on its relation with death were lacking,” says Esther Lopez-Garcia, PhD, the study’s lead author. “Coffee consumption was not associated with a higher risk of mortality in middle-aged men and women. The possibility of a modest benefit of coffee consumption on heart disease, cancer, and other causes of death needs to be further investigated.”
Women consuming two to three cups of caffeinated coffee per day had a 25 percent lower risk of death from heart disease during the follow-up period (which lasted from 1980 to 2004 and involved 84,214 women) as compared with non-consumers, and an 18 percent lower risk of death caused by something other than cancer or heart disease as compared with non-consumers during follow-up.
For men, this level of consumption was associated with neither a higher nor a lower risk of death during the follow-up period (which lasted from 1986 to 2004 and involved 41,736 men).
The researchers analyzed data of 84,214 women who had participated in the Nurses’ Health Study and 41,736 men who had participated in the Health Professionals Follow-up Study. To be in the current study, participants had to have been free of cancer and heart disease at the start of those larger studies.
The study participants completed questionnaires every two to four years that included questions about how frequently they drank coffee, other diet habits, smoking, and health conditions. The researchers then compared the frequency of death from any cause, death due to heart disease, and death due to cancer among people with different coffee-drinking habits.
Among women, 2,368 deaths were due to heart disease, 5,011 were due to cancer, and 3,716 were due to another cause. Among men, 2,049 deaths were due to heart disease, 2,491 were due to cancer, and 2,348 were due to another cause.
While accounting for other risk factors, such as body size, smoking, diet, and specific diseases, the researchers found that people who drank more coffee were less likely to die during the follow-up period. This was mainly because of lower risk for heart disease deaths among coffee drinkers.
The researchers found no association between coffee drinking and cancer deaths. These relationships did not seem to be related to caffeine because people who drank decaffeinated coffee also had lower death rates than people who did not drink coffee.
The editors of Annals of Internal Medicine caution that the design of the study does not make it certain that coffee decreases the chances of dying sooner than expected. Something else about coffee drinkers might be protecting them. And some measurement error in the assessment of coffee consumption is inevitable because estimated consumption came from self-reports.

Migraines affect more than 36 million Americans – that’s nearly one out of every ten people! It’s also in the top twenty disabilities that cause people to miss work. The thing is, if they all knew this secret to curing and preventing these chronically severe headaches, that number would see a drastic reduction.
