This Is What Coffee & Tea Could Do To Your Brain
According to a number of recent studies, coffee and tea could keep your brain healthy, and provide protection against Alzheimer's disease, Parkinson's disease and depression. This is good news, at least for the approximately 70 million Americans who consume three cups of coffee a day (and the overwhelming 21 million of them who drink six or more every day). Although there have been side effects associated with coffee consumption, such as insomnia, irritability, muscle tremors, and more, if consumed responsibly, coffee and tea seems to have several health benefits.
One example comes from Japan, where the simple smell of coffee beans specific increases alpha waves in the brain, which are associated with relaxation and meditation. The study also found that coffee can improve productivity and focus. You can read more about this here.
A very recent and comprehensive study investigated the relationship between depression and drinking coffee, tea and soft drinks. After following about 300,000 people, researchers National Institutes of Health found that coffee consumption was associated with a slightly lower risk of depression. (Source)
According to Scientific American, "some studies suggest that coffee and tea drinkers have lower rates of cognitive decline, too, but the evidence is mixed." They go on to mention that "research in rodents has focused on specific compounds in coffee and tea supports the idea that some of these chemicals reduce the risk of Alzheimer's and Parkinson's disease."
cite a study published in June in Neurobiology of Aging, where researchers supplemented the diet of rats with a component of coffee. As a result, brains of the animals were protected against changes that occur in the brain that are typical of Alzheimer's patients.
also cite a 2013 study in which another experiment found the same compound that has protective effects against Parkinson's disease in mouse models.
Undoubtedly intriguing research that warrants further investigation, but it is interesting to see that science is shedding light on a drink that has always been used as a vise to receive a quick energy boost.
Another example is presented in the form of treatment for colon cancer. Among people with colon cancer in stage three, the consumption of at least four cups of coffee a day actually reduced the risk of cancer recurrence or death by more than 50 percent. Drinking at least two cups a day reduced the risk by 31 percent. (Source)
A 2007 meta-analysis found that drinking two cups of coffee a day was associated with 43 percent lower risk of liver cancer, which has also been confirmed by several other research centers. (Source)
Another meta-analysis evaluated 59 studies found that drinking a cup of coffee a day was associated with a 3 percent lower risk of cancer, and there is even research claiming that coffee may reduce the risk of skin cancer. (Source) (source)
"in vitro studies and in animals have shown that coffee components suppress skin carcinogenesis UVB-induced, induce apoptosis of cells, to protect against oxidative stress and DNA damage, reduce inflammation in epidermal cells, and inhibiting changes in DNA methylation. "
Another study found that women who drank more than three cups of coffee a day had a significantly lower risk of skin cancer compared to those who consumed less than one cup per month. (Source)
The coffee has also been implicated in reducing the risk of type 2 diabetes, and many researchers agree that it is likely that compounds found in coffee have the potential to reduce the risk of several chronic diseases.
As reported by the New York Times:
the researchers' hypothesis is that factors that increase the risk of type 2 diabetes, such as obesity, sedentary lifestyle and high insulin levels also lead to colon cancer, he said Dr. Fuchs. And many studies have shown that coffee consumption is associated with a lower risk for type 2 diabetes, a chronic disease that may increase the risk of colon cancer.
"We believe that the activation energy pathways that contribute to heart disease and diabetes is also relevant to the proliferation of cancer cells," said Dr. Fuchs, while emphasizing that you need further investigation.
The analysis determined the lowest risk associated with coffee was entirely due to caffeine. One hypothesis is that caffeine increases the body's sensitivity to insulin, thus requiring less of the hormone. Inflammation, in turn, can be reduced, which is a risk factor for diabetes and cancer.There are also a number of studies that show coffee can help with heart health, multiple sclerosis, Parkinson's disease, dementia and premature death.

said, many other studies have suggested that coffee consumption may actually increase the risk of cancer, but when meta-analysis such as that mentioned above are performed, the association seems to fade , and coffee becomes a place of protection.
What kind of coffee should be drunk?
Obviously, we would not recommend getting your coffee from a Starbucks or Tim Hortons. On the basis of all our research in the accumulation of pesticides, strongly premium, trade single origin, fair, coffee and tea it is recommended - organic is prime. Conventional coffee often the use of fertilizers and synthetic pesticides, with the help of genetically modified organisms is grown. Also it is processed and packaged with many chemicals. Anything with synthetic fertilizers, herbicides, pesticides, artificial flavors or preservatives really should be avoided.
Researchers have also noted that the roasted coffee contains over 1,000 compounds, many of which can help fight cancer. You can read more about this here.
What are your thoughts? Are you a coffee drinker? If so, you note a difference between when you drink coffee and he does not? Do you do anything for you? Feel free to share your thoughts in the comments section free.
