Coffee and heart health - a benefit or a risk?
If you enjoy a great cup of coffee, you may be wondering about its relationship with heart health. In recent decades, there have been many studies examining its possible links. Generally speaking, research shows that in moderation (a few cups a day) it's a safe beverage that may even offer some health benefits for the millions of North Americans who enjoy it.
Benefits
may reduce the risk of type 2 diabetesmay reduce the risk of gallstonesmay discourage the development of colon cancermay improve cognitive functionmay reduce the risk of liver damage in people at high risk for liver diseasemay reduce the risk of Parkinson's diseasemay improve performance in endurance athletesCoffee beans contain antioxidants, some of which become especially potent during the roasting process. Antioxidants are widely regarded as beneficial in helping prevent cancer, heart disease, diabetes, and stroke.
An interesting note - Italian researchers credit another compound called trigonelline, which accounts for its aroma and taste, for having antibacterial properties that can help prevent dental cavities.
Risks
The main ingredient, caffeine, is a mild addictive stimulant. Too much may cause nervousness, the jitters, or trembling in some people. And, caffeine does have modest cardiovascular effects such as increased heart rate, increased blood pressure, and occasional irregular heartbeat. Too much can even raise cholesterol levels, so experts stress moderation. But most recent large studies show no significant adverse effects for the majority of people, although some heart patients may be advised to limit or avoid its consumption.
Some considerations for smart heart living:
Enjoy in moderation!Caffeine raises your blood pressure, so if you are going to drink a lot of it, choose decaf. The antioxidant benefits are the same in regular and decaf.Choose filtered over percolated or boiled as there is some evidence that compounds in unfiltered coffee may raise cholesterol.My personal choice is to use fair trade, organic,
home roasted
beans to reduce my exposure to chemical fertilizers and pesticides (plus it tastes better!)If at all possible avoid adding sugar and cream - if you can't drink it black use skim or 1% milk.In choosing to drink caffeine, go by how your body reacts. If you have concerns, talk to your doctor.
