What it is the first thing most of us after waking up? Most of us are on our way to the kitchen to prepare our first morning coffee. So, what’s in this coffee mug that makes us drink every day?
Many studies have been investigating the pros and cons of drinking coffee and while 500 billion cups are served each year and 60% of people in the world who drink coffee every day, who are still undecided or not coffee is good for us or just a mere habit.
habit or not, science give us some information about the benefits and disadvantages of both coffee. For example, onestudy showed that women who drank two to three cups of caffeinated coffee a day were 15 percent less likely to develop depression over a period of 10 years compared to women who drank one cup of coffee a week or even less. Another study showed that a cup of coffee can prevent stroke. Many more studies have shown that coffee reduces the risk of dementia, Alzheimer’s disease, Parkinson’s disease, type 2 diabetes, and more, while others showed that coffee consumption can lead to anemia due to iron deficiency, hallucination, migraines and other medical problems.
The latest study by researchers at the University of California, published in the journal Nature Neuroscience, shows that caffeine improve long-term memory. According to the study that we now have evidence that coffee can help you remember and focus.
Scientists, led by Michael Yassa, investigated how small amounts of caffeine affect memory function in adults. There were 160 participants were asked to study images of objects. These participants were given a tablet containing 200 milligrams of caffeine (two espressos) or a placebo. The volunteers returned after 24 hours and a memory test where they were to rank “old” took “new” or images “like” from the images they had seen before and those who had not. Both groups had the same distinctive new images and old. However, those volunteers who took a caffeine pill was better to identify “similar” images. The test tells us how accurate the information is stored in the brain.
After the results, Yassa concluded that caffeine improves long-term memory by improving the process of memory consolidation.
“Our study suggests that there is a real learning and memory, but other studies suggest caffeine is associated with increased longevity, and resistance to Alzheimer’s disease. In moderate amounts, can have beneficial health effects “Yassa said.
However, another test showed that coffee helps restore memory. Participants who consumed caffeine only an hour before the test did not show any positive results. The researchers made another test with higher and lower doses of caffeine, but the effects showed that two espressos are the perfect dose.
We are reminded by other scientists in the same or related fields of research that this study needs to be done in a larger number of participants, which will in the future probably. Until then, it does not depend on us, which, in my opinion, is the best choice.
Therefore, drinking two espressos a day to boost your memory! Or not do, depending on what you believe.
