Coffee is enjoyed by millions of people around the world, yet few completely understand the positive health effects this strong brew can provide. Coffee has some fantastic benefits if drank in moderation, quantity that, for most healthy adults, appears to be up to 400 milligrams a day. However, caffeine is also a stimulant that can cause problems for some people and disrupt sleep.


This article takes a detailed look at coffee’s health benefits, both at the positive and negatives ones, according to science.



  • Potent source of antioxidants – Coffee is a great source of antioxidants which are good for your heart health and may also help to lower your risk of infections and some forms of cancer. Coffee shows more antioxidant activity than green tea and cocoa, two antioxidant superstars.
  • Reduce your risk of developing diabetes – According to a study in a diabetic journal, those who drink coffee tend to have a lower risk of developing type 2 diabetes and cardiovascular disease.
  • Increases physical performance – When caffeine enters your bloodstream, it behaves like a fuel. An easy way to improve physical performance is to drink a cup of coffee roughly an hour before physically demanding exercise.
  • Improves your brain function – In addition to boosting energy levels, caffeine also assists brain function: it improves your reaction time, short term memory, and cognitive function.
  • Coffee helps you burn fat – Many fat burning supplements contain caffeine due to its fat-burning properties that are known to boost your metabolic rate by 3-11%.
  • Reduce your Alzheimer’s and Parkinson’s risk – According to a study by Scientific American, they found coffee drinkers are less likely to be affected by Alzheimer’s and Parkinson’s disease later in life.
  • Coffee can make you feel happier – Coffee’s famous for its mood-lifting effect, although its protection from depression may not be attributed to caffeine. According to research, coffee’s mood-lifting effect can be traced to its antioxidants.
  • Coffee drinkers have longer life spans – According to a recent medical study, people who drink coffee have a longer life span, as they are less susceptible to health issues such as heart disease, high cholesterol and, blood pressure.



  • Coffee Can Increase Osteoporosis – It’s true that coffee can cause the body to excrete calcium in the urine. We don’t want the body to rid itself of calcium because this can lead to osteoporosis. According to The Diet Channel, about five milligrams of calcium is lost per every six ounces of coffee consumed. But these calcium losses can be counterbalanced with two tablespoons of milk or yogurt, which they can of course be dairy-free, per cup of coffee.
  • Coffee Causes Wrinkles – Even though coffee has antioxidants, if you drink too much of it, it can cause wrinkling of the skin. This is a result of dehydration which is the worst thing for your skin. So when you’re drinking that morning cup or two, make sure that you’re pairing it with water. Even better, add 1 tablespoon of chia seeds to your water and let them sit for 30 minutes. The chia seeds keep you even more hydrated than regular water.
  • Conventional Coffee Is Laden with Pesticides – The coffee plant is one of the most heavily sprayed crops. It’s coated with chemicals, pesticides, and herbicides, nothing you’d want to be ingesting. If you do drink coffee, make sure that it’s the organic variety, free from assorted chemicals that leach into our groundwater and can make us sick down the road.

If you switch to decaffeinated coffee, make sure the caffeine is removed in a natural way without the use of chemicals to do it. Often times, conventional decaffeinated coffee has more chemicals than regular.

  • Too much coffee can make you anxious. According to the University of Oklahoma, caffeine can trigger symptoms of anxiety—especially if you have pre-existing anxiety disorders.
  • Coffee can increase blood pressure. Over time, it’s possible to develop a tolerance to the caffeine in coffee, which means you’ll need to drink more to feel the same effect. Since caffeine causes the release of adrenaline, more coffee can result in an elevated heart rate and blood pressure.
