Coffee is a brewed drink prepared from roasted coffee beans, which are the seeds of berries from the Coffea plant. This slightly acidic beverage has a stimulating effects on us caused by its caffeine content. In fact, drinking coffee in the morning is the most obvious drinking hobby of every one, even in the afternoon. Besides its irresistible aroma and taste, it's been proven to boost our performance towards our daily routines at home or in the office. However, the scientific facts uncovered pertaining to its number of health benefits come with limitations too.
The major risk factor for heart disease is atherosclerosis, the clogged arteries. But according to new study's findings, it can be reduced by drinking more than three cups of coffee everyday. Furthermore, it is found out that there is around 70 percent reduction of liver disease, and lower risks of heart attack and stroke. Indeed, the new study — which was recently published in the Journal of the American Heart Association — further suggests that coffee may protect our heart health.
The researchers from the University of São Paulo in Brazil conducted this study and it reveals that drinking at least three cups of coffee every day may lower the risk of clogged arteries, or atherosclerosis. But to clarify with, this result was in direct association with people who never smoked. According to them, never-smokers who consumed at least three cups of coffee daily had a 63 percent lower risk of coronary calcification.
"It is possible that deleterious effects of smoking overwhelm the benefits of coffee intake on early cardiovascular disease injury," the team speculates, "so this impact of coffee may occur only in people who have never smoked."
Coffee is a complex substance and — as a new study finds — its metabolic interactions are equally complex. Surprisingly, coffee influences the same regions of the brain as cannabis.
A recent finding on the study of coffee's impact in our internal chemistry is published in the Journal of Internal Medicine. The group of researchers conducted this study is fromRecently Northwestern University in Chicago, IL. They found out that the increased coffee consumption caused the metabolites involved in the endocannabinoid system to drop off. Endocannabinoid system facilitates the modulation of a whole host of metabolic activities. It includes blood pressure, cognition, addiction, immunity, appetite, csleep, and glucose metabolism.
"These are entirely new pathways by which coffee might affect health," notes Cornelis. "Now, we want to delve deeper and study how these changes affect the body." Since endocannabinoid system influences the eating behavior, it has potential way of explaining the "the link between cannabis use and the munchies." Also, as coffee seems to have a link with endocannabinoids system, she said Our new findings linking coffee to endocannabinoids," she adds, "offer alternative explanations worthy of further study." Moreover, it is discovered that coffee has the ablity to help achieve weight loss and reduce type 2 diabetes risk.
However, there is a precaution in drinking coffee.
"Drinking more coffee was also found to increase metabolites from the androsteroid system. This infers that coffee speeds up the excretion of steroids. And, because steroids are involved in a number of conditions — notably cancers — coffee could, potentially, play a part here, too.
We love a caffeine kick in the morning or anytime of the day, especially the athletes. Caffeine stimulates our nervous system as manifested in a reduced fatigue and drowsiness. It can even improve endurance and increase muscular strenth. Hence, they believe that it boosts their sports performance. However, new research suggests that it is better that they lay off drinking coffee and energy drinks in their free time. Regular drinking of coffee may desensitize desensitize athletes to the performance-enhancing effects of the caffeine.
Dr. Brendan Egan, of the School of Health and Human Performance at Dublin City University in Ireland, and colleagues recently reported their findings in the International Journal of Sport Nutrition and Exercise Metabolism. They found out that three or more cups of coffee every day tends to decrease the athletic performance. So, they recommend to cut down drinking coffee to reap the rewards of caffeine supplements.
Drinking coffee has two separate impacts on our health. While it is known to boost performance, facilitate weight loss, and reduced risk of developing diabetes, it has adarker side also. A long-term intake of it can exacerbate the symptoms of Alzheimer's disease.
Lead researcher Dr. Lydia Giménez-Llort — from the Universitat Autònoma de Barcelona in Spain — and colleagues recently reported their results in the journal Frontiers in Pharmacology.
The study revealed that rodents that drank the caffeinated water had greater BPSD — including anxiety and neophobia, or a fear of unfamiliar objects or situations — compared with those that consumed plain water. Furthermore, they found that caffeine had little benefit for learning and memory in the rodents.
Hence, it is best to exercise precaution in drinking coffee according to Dr. Gimenez-Llort and colleagues.
"These results confirm that caffeine, despite its everyday use and relative lack of government regulation, is a potent compound with multifaceted effects," say the authors, adding:
"We speculate that over a chronic treatment with caffeine, the exacerbation of anxiety-like BPSD symptoms may partially interfere with the beneficial cognitive effects to the extent that they can be in the opposite direction."
In the previous study (2012) by Canadian researchers, there was a hopeful insight of drinking coffee in relation with Parkinsons. They believed that it can ease the symptoms of Alzheimer's disease. However, 5 years after they revealed different finding, coffee compound is not actually beneficial at all.
Dr. Ronald B. Postuma, of McGill University in Canada, and colleagues recently reported their results in the journal Neurology. "Regardless, our core finding is that caffeine cannot be recommended as therapy for movement symptoms of Parkinson's disease."
Nevertheless, coffee has another benefits to patients with HIV, hepatitis C.
A wealth of studies have hailed coffee for its potential health benefits, but for patients infected with both HIV and hepatitis C virus, the rewards could be even greater; a new study suggests that drinking at least three cups of coffee per day could halve their risk of all-cause mortality.
Lead investigator Dominique Salmon-Céron, Ph.D. - of the Service des Maladies Infectieuses et Tropicales, Hôpital Cochin, and Université Paris Descartes in France - and colleagues recently reported their findings in the Journal of Hepatology. They found out that coffee compounds called polyphenols can reduce the inflammation and protect liver health. But Dr. Salmon-Céron and colleagues note that researchers have not investigated how coffee intake affects the mortality risk of people co-infected with HIV and HCV - until now.
Its been recommended to drink tea for its health benefits but coffee is not behind it. Caffeine consumption has positive impact on women with diabetes. Just for one cup of coffee everyday, there is 50 percent significant reduction of mortality risk. This finding is made by new research presented by the European Association for the Study of Diabetes annual meeting, held in Lisbon, Portugal.
The study - which was jointly led by Dr. João Sérgio Neves and Prof. Davide Carvalho, both from the University of Porto in Portugal - examined the link between consuming different amounts of caffeine and mortality risk among men and women with diabetes.
"Previous studies have shown that consumption of coffee or tea is associated with improved insulin sensitivity and better control of postprandial glycemia in patients with diabetes."
"Furthermore," Dr. Neves added, "the minerals, phytochemicals, and antioxidants present in the caffeine-containing beverages may also contribute to the benefit seen in women's mortality."
Researchers have found that cafestol - a bioactive compound present in coffee - increased insulin secretion, reduced fasting glucose levels, and improved insulin sensitivity in mice. Study co-author Fredrik Brustad Mellbye, of the Department of Endocrinology and Internal Medicine at Aarhus University Hospital in Denmark, and colleagues recently reported their results in the Journal of Natural Products
