Here are the top 12 evidence- based health benefits of coffee, as confirmed in medical studies:
- Improve Energy and Make You Smarter – This is because it contains a stimulant called caffeine, which is the most commonly consumed psychoactive substance in the world. Many controlled trials in humans show that coffee improves various aspects of brain function. This includes memory, mood, vigilance, energy levels, reaction times and general cognitive function.
- Help You Burn Fat – Caffeine is one of the very few natural substances that have actually been proven to aid fat burning. Several studies show that caffeine can boost the metabolic rate by 3-11%. Other studies show that caffeine can specifically increase the burning of fat, by as much as 10%.
- Drastnaline) levels in the blood. This is the “fight or flight” hormone, designed to make our ically Improve Physical Performance – Caffeine also increases Epinephrine (Adrebodies ready for intense physical exertion. Caffeine can improve physical performance by 11-12%, on average. Because of this, it makes sense to have a strong cup of coffee about a half an hour before you head to the gym.
- Essential Nutrients – A single cup of coffee contains: Riboflavin (Vitamin B2): 11% of the RDA, Pantothenic Acid (Vitamin B5): 6% of the RDA, Manganese and Potassium: 3% of the RDA, Magnesium and Niacin (B3): 2% of the RDA.
- Lower Your Risk of Type II Diabetes – For some reason, coffee drinkers have a significantly reduced risk of developing type 2 diabetes. The studies show that people who drink the most coffee have a 23-50% lower risk of getting this disease, one study showing a reduction as high as 67%.
- Protect You From Alzheimer’s Disease and Dementia – Several studies show that coffee drinkers have up to a 65% lower risk of getting Alzheimer’s disease.
- Lower The Risk of Parkinson’s – In studies, coffee drinkers have a much lower risk of developing Parkinson’s disease, with a reduction in risk ranging from 32-60%.
- Appears to Have Protective Effects on The Liver – It turns out that coffee may protect against cirrhosis. People who drink 4 or more cups per day have up to an 80% lower risk.
- Fight Depression and Make You Happier – In a Harvard study published in 2011, women who drank 4 or more cups per day had a 20% lower risk of becoming depressed.
- Lower Risk of Some Types of Cancer – Studies show that coffee drinkers have up to a 40% lower risk of liver cancer. One study of 489,706 individuals found that those who drank 4-5 cups of coffee per day had a 15% lower risk of colorectal cancer.
- May Lower The Risk of Stroke
– It is often claimed that caffeine can increase blood pressure. This is true, but the effect is small (3-4 mm/Hg) and usually goes away if you drink coffee regularly. However, studies do NOT support the myth that coffee raises the risk of heart disease. In fact, there is some evidence that women who drink coffee have a reduced risk of heart disease. Some studies also show that coffee drinkers have a 20% lower risk of stroke.
- May Help You Live Longer – Given that coffee drinkers are less likely to get many diseases, it makes sense that coffee could help you live longer. In two very large studies, drinking coffee was associated with a 20% lower risk of death in men and a 26% lower risk of death in women, over a period of 18-24 years.
