After years of research looking at the health effects of drinking coffee, you’d be forgiven if you were not clear whether this is good or bad for you. Scientists have known for some time that coffee affects different people in different ways. A recent study published in the journal Molecular Psychiatry brings us closer than ever to know why. The researchers analyzed the complete DNA sequence of 120 thousand drinkers of European and African-American coffee and found at least eight places on our genes that are associated with the consumption of coffee, six were never related coffee before. Although there are many other compounds in coffee that have biological effects, the study reinforces the idea that caffeine motivates regular consumption of coffee. The study could explain why a java drinker will be wired all day after one cup, and one is able to have an espresso before going to bed and fall asleep quickly. If you feel like you want constant caffeine and cannot function without your six cups a day, blame it on your genes.
You and Coffee – The Relationship with Dos and Don’ts
Reasons to How Coffee is good for you:
Coffee stimulates your mood. Many studies show that caffeine increases alertness and reduced fatigue. This effect has been demonstrated in people who a jolt of morning need should stay up late, needed to fight against the loss of sleep or fight the cold. It works even in people who are already in a state of alert. The caffeine is in blocking the effects of adenosine receptors in the heart and the brain, causing a stimulation of the growth of the central nervous system and heart rate.
Coffee perks up cognitive performance. The science shows that caffeine has beneficial effects on psychomotor speed and alertness. It improves performance in tasks requiring working memory, especially when you are tired or fatigued. It has not; however, appear to affect the long-term memory. Most studies have also found an improvement in simple reaction time and choice, expressed in real life tasks like driving.
Coffee improves athletic performance. Coffee improves physical performance, whether endurance sports, stop-and-go sports (team and racquet sports), or high intensity sports (swimming, rowing, and middle distance). The effects of caffeine on single events involving strength and power such as lifts- throws and sprints are not clear. However if the coffee gets you out of bed and into the gym at 6am, consider a boost physical performance. You are reading You and Coffee – The Relationship with Dos and Don’ts.
Coffee prevents diabetes type 2 The first study suggest that regular coffee drinking reduces levels of blood sugar and may protect against the development of diabetes was published in 1970 Since then, many studies and meta-analyzes corroborated the findings in several parts of the world in different ethnic groups. Based on observational studies, more coffee you drink, and the lower risk of diabetes. This effect, however, is not solely due to caffeine as decaffeinated coffee has a stronger association.
Coffee prevents liver cancer. In a large multi-ethnic study involving more than 162,000 participants, those who drank 2-3 cups of coffee per day had a 40% lower risk of liver cancer and chronic liver disease. Caffeine and other compounds of coffee seem to affect liver enzymes and the development of cirrhosis, regardless of gender, alcohol consumption, or a history of hepatitis or liver disease. Drinking coffee can actually protect you against the harmful effects of excessive alcohol and even help to overcome the hangover consumption. There is also evidence to suggest coffee can help protect against other cancers, including skin cancer and cancer of the prostate aggressive.
The Dark Side:
For many of us coffee can be a real pick-me. But ask yourself why you reach for the cup first. Is it really just to get a boost or is it a band-aid for a larger problem? Chronic sleep deprivation- poor stress management-poor diet-hormonal imbalances-lack of physical activity-lack of adequate sunlight or any other number of lifestyle factors need to be addressed before you can hope reap the health benefits of coffee. Caffeine is there to help us pass the course of daily life but for some people it can lead to health problems. You are reading You and Coffee – The Relationship with Dos and Don’ts.
Coffee causes heart attack. The risk of a heart attack possibilities induced by coffee or caffeine actually depends on your genes. People metabolize caffeine at different rates depending on the activity of liver enzymes. If you’re the type who gets the jitters after a cup of Joe, you’re probably slower metabolizing. Studies suggest that if you’re a slow metabolize you are more likely to have a nonfatal heart attack. On the other hand if you are a fast metabolizer coffee will actually defend you against heart attacks. The difference in your genetics is probably why it was so much conflicting research on the cardiovascular effects of coffee. Some studies report an increased risk of cardiovascular disease of moderate coffee consumption high, and others report no effect at all – even if you have up to six cups a day. Keep in mind that it is difficult to separate from other factors that generally surround the consumption of coffee.
Coffee causes intestinal disorders. Coffee stimulates the secretion of gastric juice (hydrochloric acid). Increasing the production of acid in the stomach and the ability of coffee to relax the lower esophageal sphincter may contribute to acid reflux and heartburn. The coffee can also irritate the lining of the small intestine and can exacerbate the symptoms of the ulcer, gastritis, irritable bowel syndrome and Crohn’s disease.
Coffee gives insomnia. Recall the stimulant activity of this coffee is due to the ability of caffeine to block adenosine receptors in the body. There is a common genetic variant of the receptor gene that appears to be very sensitive to caffeine affects. People who are classified as Sensitive to Caffeine probably have this gene variant and generally reduce caffeine consumption voluntarily because it affects the quality of their sleep. When they try to sleep after a cut, the changes induced by caffeine in their brain electrical activity during sleep the brain looks like insomniacs. Another genetic variant of adenosine receptor causes feelings of anxiety and panic induced by caffeine. This does not mean that anxious people are necessarily subject insomniacs should avoid coffee.
In researchers’ conclusion, our results support the hypothesis that metabolic and neurological mechanisms contribute to caffeine consumption habits of coffee. It’s pretty obvious now that our thirst for caffeine is in our genes and can be hereditary but there are still many questions surrounding the coffee that must be answered. What kind of coffee is healthier? What is the method of preparation is healthier? Do cream and sugar by adding make a difference?
If You go Black:
Coffee purists are not the only ones campaigning to keep the black coffee. Almost all research on coffee was done without additional ingredients. While the cream and sugar are common additions, add some cinnamon – vanilla – cardamom & even butter. Ever heard of Dave Asprey Bulletproof coffee made with unsalted grass-fed butter and coconut oil…? Little is known about how these ingredients interact with the chemistry of coffee and how they affect the metabolism of caffeine. We know that sugar in all its forms is not a healthy substance. Gourmet coffees with sweet syrups and whipped cream are extremely popular and help as many calories as soft drinks. The milk and cream could play a role in reducing the risk of cardiovascular disease or diabetes.
Being Aggressive in anything is bad for you
Actually, too much of anything is bad for you. The lethal dose of caffeine is about 10 grams. People usually drink only 1-2 mg / kg of caffeine per drink and it would take about 50 gallons of coffee to die from an overdose of caffeine. The handful of deaths attributed to Caffeine Toxicity from the ingestion of too much energy drinks is usually due to more adverse factors working together with caffeine such as alcohol or a heart condition preexisting. Keeping this in mind how do we know that enough is enough? Rest assured that the research did not find any relationship between coffee consumption and increased risk of death from all causes, death a cancer or death from cardiovascular disease even in people who drank up to six cups of coffee per day.
