Coffee isn't healthy. I mean, I don't think it will kill you, but it isn't going to benefit your health in any way.
Sorry I cannot help more. I just know that caffeine is very bad for you. In many different ways too. Plus, coffee stains your teeth. Those are the only things I know of! But good luck to ya on this one!

Actually coffee does have benefits which come from its antioxidants.

is drinking coffee a healthy habit?
By: peinie p. Tsai pharmd

recently the media has been brewing over coffee as a new potential health food. Along with an extensive list of possible benefits, the most notable claim is that coffee may prevent type 2 diabetes! However, before you rush out and treat yourself to a venti espresso macchiato with the excuse that you're doing something healthy, there are some things you should consider.

First the news:

a very large study of over 120,000 men and women, who were followed for almost twenty years, indicates that there is a significantly lower incidence of type 2 diabetes (also known as, adult-onset diabetes) in coffee-drinkers versus non-drinkers. 1 similar conclusions were found in two other studies published in lancet and the journal of internal medicine. 2,3 all studies found a dose relationship between coffee and the frequency of diabetes. This means that people who drink more coffee have a decreased probability of developing type 2 diabetes compared to those who drink less coffee. 3 however, drinking decaffeinated coffee does not seem to have any effect on type 2 diabetes incidence. Other caffeine containing beverages, such as cola, were not studied.

What this means:

the relationship concluded by multiple studies indicates that high coffee consumption, of six or more cups of coffee per day, appears to be beneficial in preventing the onset of type 2 diabetes.

Why this might be:

it is unclear whether long-term coffee drinking somehow increases sugar metabolism in the body, thereby decreasing risk of type 2 diabetes. It is possible that coffee beans contain antioxidants or compounds that alter insulin sensitivity. Another thought is that caffeine increases metabolism and suppresses hunger. Excessive coffee drinkers are less likely to be overweight or over-eaters and therefore are usually not obese, which is itself a predominant risk factor for developing type 2 diabetes.

Things to remember:

there are no studies to explain the mechanism behind the current findings of an inverse relationship between coffee intake and type 2 diabetes incidence. If you are currently a heavy coffee-drinker, then there is some promise that this habit may be beneficial. However, currently there is not enough understanding or specific evidence to support drinking coffee as a means of type 2 diabetes prevention or for people to otherwise increase their java intake.
Excessive coffee should be avoided in pregnant women, and patients with heart disease, high cholesterol, or osteoporosis. Furthermore, adding excessive amounts of cream or sugar to your morning cup can potentially turn drinking coffee into an unhealthy habit.

Weird.....
But caffeine is still bad for you, and coffee will stain your teeth!!!Lol.
I dunno. I personally cannot have caffeine, so I never got into the whole coffee thing. Every once in a while I do crave a cup, so I brew some decaff and fill it with french vanilla cream, yummmm.

There is still some debate going on but the general opinion is that it is best avoided. Try moving over to herbal teas for maximum health benefit.


However, for the amount that you drink it, it will hardly do any harm whatsoever and if you enjoy it why not drink it in small quantities? The first rule you get taught on a nutrition degree is no food is bad in small quantities, it means that as long as your diet in general is healty you can afford the odd 'bad' thing here and there.

Hi, My reviews say that Coffee is not at all a cause for ill health...but it should not be taken in full doses...anything if taken more than the limit, it causes damage....coffee can be taken twice per day...which is not harm but gives health also..

cheers,

IMHO caffine in any form is not good for you. Alot of health risks go along with heavy amounts of caffine.
I have high blood pressure and caffine is a real "no,no" in my diet. Caffine can cause the heart to palpatate and get really fast "tacky". But, if your a morning coffee drinker, that should be alright.

Just my opinion.

The biggest problem with coffee is it's acidity. If you don't balance the acid with alkaline food and drinks, coffee will wear down your body over time. It will migrate to the weakest area of your body and worsen it like a rotten apple in a barrel. To prevent this eat plenty of alkaline foods like cucumber, celery and plenty of green vegetables, preferably raw. Juice them to make them more palatable. For a quick fix, place a teaspoon or 2 of bicarbinate of soda in a glass of water and drink it down. Stay alkaline and you will never suffer from acid reflux as you get older.
