Mayo Clinic Article

Anyways here are some interesting findings in Mayo Clinic article:

• Coffee no longer shows any link to cancer / heart disease:

Recent studies have generally found no connection between coffee and an increased risk of cancer or heart disease. Why the apparent reversal in the thinking about coffee? Earlier studies didn't always take into account that known high-risk behaviors, such as smoking and physical inactivity, tended to be more common among heavy coffee drinkers at that time.

• Studies show coffee is linked with protecting against Parkinson's, type 2 diabetes and liver cancer because of it's high content of antioxidants:

Newer studies have also shown that coffee may have benefits, such as protecting against Parkinson's disease, type 2 diabetes and liver cancer. And it has a high content of antioxidants.

• The doctor, Donald Hensrud, in this article indicates that the only downside to coffee is that it doesn't contain any nutrients compared to its counterparts and that you should use coffee in moderation:

But this doesn't mean you should disregard the old maxim "Everything in moderation." Although coffee may not be very harmful, other beverages such as milk and juice contain nutrients that coffee does not. Also, keep in mind that coffee accompaniments such as cream and sugar add fat and calories to your diet. Finally, heavy caffeine use — on the order of four to seven cups of coffee a day — can cause problems such as restlessness, anxiety, irritability and sleeplessness, particularly in susceptible individuals.

The Good:

• Coffee decreases instances of MRSA in a persons nose. A most recent study shows that coffee / tea drinkers are less likely to carry methicillin-resistant Staphylococcus aureus (MRSA) in their noses. This means coffee / tea have anti-microbiological impacts. However, the link between MRSA and systemic infection have not been linked.

• Coffee Decreases ones risk in Prostate Cancer* In may, Journal of National Cancer Institute found that coffee contains biologically active compounds that can be associated with reduced risk of cancer.

• Long term coffee consumption reduces risk of type-2 diabetes; Indicating Coffee seems to improve insulin sensitivity

Overall, so far the jury is out that coffee can be substantially important in reducing risks of cancer, and various other diseases; just limit your intake.

The bad:

• Coffee Drinkers have 20% increased risk of urinary tract cancer
• Excessive drinking of coffee can increase chances of lung cancer Unfortunately, the abstract indicates that results were inconsistent

Overall:

I would just stick to your guns and do what you feel is right. I would continue to consume coffee. It seems as there are a lot of perks of coffee. I would of course, as stated previously, enjoy coffee in moderate amounts.
