The health impact of coffee has long been a controversial topic, with advocates touting its antioxidant activity and brain-boosting ability, and detractors detailing downsides such as insomnia, indigestion and an increased heart rate and blood pressure. But the latest wave of scientific evidence brings a wealth of good news for coffee lovers. Here are reasons drinking coffee may be healthier for you than you thought.
Coffee is a potent source of healthful antioxidants.
In fact, coffee shows more antioxidant activity than green tea and cocoa, two antioxidant superstars. Scientists have identified approximately 1,000 antioxidants in unprocessed coffee beans, and hundreds more develop during the roasting process.Antioxidants fight inflammation, an underlying cause of many chronic conditions, including arthritis, atherosclerosis and many types of cancer.
. Caffeine provides a short-term memory boost.
When a group of volunteers received a dose of 100 milligrams (mg) of caffeine, about as much contained in a single cup of coffee, Austrian researchers found a surge in the volunteers’ brain activity, measured by functional magnetic resonance imagery (fMRI), as they performed a memory task. The researchers noted that the memory skills and reaction times of the caffeinated volunteers were also improved when compared to the control group who received a placebo and showed no increase in brain activity.
Caffeine appears to affect the particular areas of the brain responsible for memory and concentration, providing a boost to short-term memory, although it’s not clear how long the effect lasts or how it may vary from person to person.
Coffee may help protect against cognitive decline.
In addition to providing a temporary boost in brain activity and memory, regular coffee consumption may help prevent cognitive decline associated with Alzheimer’s disease and other types of dementia. In one promising Finnish study, researchers found that drinking three to five cups of coffee daily at midlife was associated with a 65 percent decreased risk of Alzheimer’s and dementia in later life. Interestingly, the study authors also measured the effect of tea drinking on cognitive decline, but found no association.
Coffee is healthy for your heart.
A landmark Dutch study, which analyzed data from more than 37,000 people over a period of 13 years, found that moderate coffee drinkers (who consumed between two to four cups daily) had a 20 percent lower risk of heart disease as compared to heavy or light coffee drinkers, and nondrinkers.
Coffee may help curb certain cancers.
Men who drink coffee may be at a lower risk of developing aggressive prostate cancer. In addition, new research from the Harvard School of Public Health suggests that drinking four or more cups of coffee daily decreased the risk of endometrial cancer in women by 25 percent as compared to women who drank less than one cup a day. Researchers have also found ties between regular coffee drinking and lower rates of liver, colon, breast, and rectal cancers.
Coffee may lessen your risk of developing type 2 diabetes.
A growing body of research suggests an association between coffee drinking and a reduced risk of diabetes. A 2009 study found that the risk of developing diabetes dropped by 7 percent for each daily cup of coffee.
Your liver loves coffee.
It’s true: In addition to lowering the risk of liver cancer, coffee consumption has been linked to a lower incidence of cirrhosis, especially alcoholic cirrhosis.
Coffee can enhance exercise performance.
We’ve been conditioned to believe that caffeine is dehydrating, one of the primary reasons why fitness experts recommend nixing coffee pre- and post-workout. However, recent research suggests that moderate caffeine consumption — up to about 500 mg, or about five cups per day — doesn’t dehydrate exercisers enough to interfere with their workout. In addition, coffee helps battle fatigue, enabling you to exercise longer.
Coffee curbs depression.
Multiple studies have linked coffee drinking to lower rates of depression in both men and women. In several studies, the data suggested an inverse relationship between coffee consumption and depression: in other words, heavy coffee drinkers seemed to have the lowest risk (up to 20 percent) of depression.
In order to take advantage of the beneficial properties of coffee, it is advisable to consider the following tips:
Choose healthy, organic coffee beans with a rich aroma. Avoid all kinds of refined, aromatic, instant coffee and pre-ground coffee.
Coffee beans before grinding and under no circumstances boil. Antioxidants are retained at such times.
Avoid drinking coffee on an empty stomach, especially in the morning. It will cause dehydration and increase acidity. If you drink coffee after meals and proper hydration, it will help digestion and increase your energy.
For maximum healthy effect, enjoy coffee without sugar. Avoid synthetic sweeteners and refined milk cream. You can enjoy 4 cups (1 cup per 100 g) of coffee daily.
