Well that sounds boring! But really, I think we all know that almost anything in moderation is good for us. The good news is that Coffee falls into this category too!! Research has shown that the benefits of coffee outweigh the risks for the majority of adult consumers. Let's review some of the facts, shall we?
Coffee has a relatively high level of antioxidantsregardless of roast type, and has even been found to be the number one source of antioxidants in the US diet (mainly due to the amount of coffee drank in the US, compared to the amount of vegetables and other super-oxidant foods). Antioxidants are key fighters of inflammation which is linked to cancer, cardiovascular diseases, and more.
Coffee can help reduce fat: caffeine triggers production of epinephrine, or adrenaline, which searches out fat tissue and sends signals tobreak it down. Caffeine also increases your resting metabolic rate, which causes fat to burn!
In a lengthy study following '48,464 women in the Nurses' Health Study (NHS; 1986-2006), 47,510 women in NHS II (1991-2007) and 27,759 men in the Health Professionals Follow-up Study (HPFS; 1986-2006), coffee has shown to decrease your riskof developing Type 2 Diabetes
Chronic liver disease and cirrhosis is the 11th cause of death in the US. Multiple studies have indicated the caffeine and chlorogenic compounds in coffee have been responsible in reducing liver fibrosis and carcinogenesis, highlighting the hepatoprotective qualities of coffee overall.
The list of coffee goodness goes on, and on, and on...
So what does all this mean? There are an incredible number of ongoing experiments and clinical studies occurring right now that are looking into the pros and cons of coffee and its chemical compounds (see references below to get into more of the details). Just like anything else, we don't know every piece to the puzzle, but what we do know so far helps me to rationalize my 2-3 cups/day routine! :-)
Please note: I'm not a doctor, I'm a scientist! Always ask your doctor if you're not sure what the impact of coffee and caffeine will have on your system.
