Is coffee good for you? Continued here, Part II

I keep being “hammered” with questions about coffee: Is it good or bad for you? It is definitely good for you. Here is a deeper look into the science behind that conclusion: 1. Excellent source of “Antioxidants” Antioxidants are various compounds that inhibit “oxidation” which is chemical reaction in your body that may damage your cells. Antioxidants are very good for you and coffee is one of the best sources we have for antioxidants. Coffee is particularly rich in hydro-cinnamic acids and polyphenols, both very effective at preventing oxidative stress.


Many observational studies indicate that coffee drinkers have a lower risk of death, in fact up to a 20% reduced risk of death in men and a 26% decreased risk of death in women, over 18–24 years study. Observational studies cannot conclude as firmly on the correlation between coffee and longevity, but the correlation efficient is very strongly there. Maybe it is the antioxidants, or it is the social setting of sharing coffee with someone, or just feeling less stress, -it is hard to say. 2. Reduced risk of heart disease and stroke Especially for women there seems to be strong evidence that drinking coffee can reduce chance of heart diseases. A large study published in the International Journal of Cardiology found no support that coffee consumption increases the long-term risk of coronary heart disease, and quite on the contrary concluded that habitual moderate coffee drinking was associated with a lower risk of heart diseases in women.


3. Reduced risk of some types of cancer There is abundant evidence that coffee can protect you against certain types of cancer, especially liver and colorectal cancer. Several studies have shown that regular coffee drinking can significantly reduce the probability of liver cancer and similarly studies show that people drinking about 4–5 cups of coffee per day have much lower risk of colorectal cancer


4. Reduces stress and depression Coffee significantly reduces your stress levels, and several large scale studies showed that people who drink 3-5 cups of coffee every day have much lower risk of becoming depressed and more than 50% less likely to die by suicide .

5. Significantly reduces the risk of Alzheimer’s disease Drinking 4-5 cups of coffee every day will conclusively reduce your chance of having the world’s most common neurodegenerative disease as well as the leading cause of dementia worldwide. As you may know there is no known cure for Alzheimer’s, but coffee seems to be one of the key things that can prevent Alzheimer’s from occurring in the first place. Several studies have shown that coffee drinkers have up to a 65% lower risk of Alzheimer's disease .

6. Reduces risk of Parkinson disease A very encouraging scientific finding is that coffee has a 32–60% strong effect in reducing the chance of Parkinson's disease, the second most common neurodegenerative condition (behind Alzheimer's disease). Coffee keep dopamine neurons relatively high in your brain fighting off the chances of Parkinson. As there is no cure for Parkinson, the effect of coffee is extraordinary useful .

7. Reduces your risk of developing Diabetes 2 A global health problem is type 2 diabetes with millions of people affected worldwide. Type 2 diabetes essentially is elevated blood sugar levels caused by insulin resistance or a reduced ability to secrete insulin. Studies show that coffee drinkers have more than a 23–50% lower risk of getting type 2 diabetes disease . Notes
