On his nutrition-focused website, Nutritionfacts.org, physician and New York Times bestselling author, Michael Greger, cites growing evidence that supports the many health benefits of coffee consumption. For instance, an analysis performed earlier this year, of the best studies published to date, indicates that coffee consumption may lead to a modest reduction in overall cancer incidences.
Coffee is loaded with all kinds of beneficial nutrients and antioxidants that can contribute toward improving one’s overall health. It also contains caffeine, which can impart energy and improve one’s mood.
When people consume coffee, the caffeine blocks the adenosine, which is an inhibitory neurotransmitter. When this happens, other neurotransmitters, such as dopamine and norepinephrine increase, and enhances the brain’s firing of neurons. This can lead to marked improvements in memory, energy levels, mood and general cognitive function.
Coffee can also be useful for weight loss. A number of recent studies suggest that caffeine can help burn fat in the body. The beverage has also been shown to boost the body’s metabolic rate. Coffee has also been shown to increase the body’s adrenaline levels by releasing the fatty acids found in fat tissues. This can lead to improvements in physical performance.
Many people are unaware of the fact that coffee contains many beneficial nutrients. A single cup of the beverage contains 2% of the recommended daily allowance of Magnesium and Niacin and 3% of the daily recommended dosage of Manganese and Potassium. It also contains Pantothenic Acid, which is used to metabolize fats, carbohydrates and proteins in the body. Coffee also contains as much as 11% of the recommended daily allowance of Vitamin B2 or Riboflavin.
Type II. Diabetes
Recent observational studies suggest that people who consume coffee regularly have less chances of contracting type II. diabetes. Currently, approximately 300 million people are afflicted with this serious disease worldwide.
Overall, coffee is a healthful beverage for the general population. However, like any other food or beverage, the consumption of coffee has some caveats for certain individuals. People with insomnia, heartburn, anxiety, high blood pressure and specific heart-related rhythm irregularities should consult with their physicians to determine the safest levels to drink. Certain compounds found in coffee have been shown, in some cases, to increase cholesterol levels. However, Dr. Greger cites evidence suggesting that these compounds can be effectively removed when the coffee is filtered through paper filters. Therefore, drip coffee is the preferred brewing method over French press, boiled or espresso. Coffee should be limited to two cups per day for women who are pregnant.
