Is coffee good or bad for the heart?

Yeah only excess drinking of coffee increase risk of heart disease but limited drinks do not. Coffee has many usefulness in other disease too. But excess coffee consumption may lead to a magnesium deficiency or hypomagnesaemia, and may be a risk factor for coronary heart disease. It may have a mixed effect on short-term memory, by improving it when the information to be recalled is related to the current train of thought, but making it more difficult to recall unrelated information. Nevertheless, the mainstream view of medical experts is that drinking three 8-ounce (236 ml) cups of coffee per day (considered average or moderate consumption) does not have significant health risks for adults. Such as Coffee appears to reduce the risk of Alzheimer's disease, Parkinson's disease, heart disease, diabetes mellitus type 2, cirrhosis of the liver, and gout. Some health effects are due to the caffeine content of coffee, as the benefits are only observed in those who drink caffeinated coffee, while others appear to be due to other components. For example, the antioxidants in coffee prevent free radicals from causing cell damage. Coffee's negative health effects are mostly due to its caffeine content. Research suggests that drinking caffeinated coffee can cause a temporary increase in the stiffening of arterial walls. Coffee beans can restore the appetite after cooking and refresh olfactory receptors. People can regain their appetite by smelling coffee beans.

When I was in the hospital following heart surgery, I could not get a cup of coffee to save my soul! Based on that, I'd say the medical profession is against coffee for heart health. However, a caveat against drinking coffee was not part of the instructions I received when I left the hospital. In addition, I'd like to comment that the rules keep changing!

A cup or two per day should not cause any problem. That way, there are so many things (some liquids and some solids) which we consume are also harmful. But then it depends on the level one maintains. If it is within limits, then it is ok.

the first and the last time I drank coffee was during my finals back in my student nurse days just to keep me awake for studying but it only caused me palpitations.... so i guest it's bad for the heart based on experience.
