The Relationship Between Coffee and Heart Health: It’s Good Or Bad

The Relationship Between Coffee and Heart Health: It's Good Or Bad

The relationship between Coffee and Heart Health was once considered “harmful”. Coffee is thought to increase the risk of heart attacks and arrhythmias as well as blood pressure and cholesterol. These notions have been disproved by recent research, which raises the possibility that coffee may benefit heart health.

Previous research often overlooked other Coffee and Heart Health risk factors, like obesity and smoking. Regular moderate coffee consumption had little or no effect on a person’s risk of heart disease when these variables were considered. Coffee consumption in some cases significantly reduces the risk.

This article examines the most recent research on the effects of coffee consumption on cardiovascular health, including instances in which it may lower the chance of developing specific heart conditions. Let’s find out with tiyug!

Coffee and Heart Health: Blood Pressure

Depending on the user, coffee can have different effects on blood pressure. When non-coffee users are suddenly exposed to caffeine, their blood pressure can rise by as much as 10 mm Hg. However, the same amount of caffeine doesn’t seem to have an impact on regular coffee drinkers.

When you regularly drink coffee, according to research in the American Journal of Clinical Nutrition, your body will quickly get used to the effects of caffeine. Coffee will eventually lose its blood pressure-raising effect and be less likely to make you jittery.

The results are supported by a 2021 review published in Current Hypertension Reports, which concluded that a person’s blood pressure was not significantly affected by moderate and regular coffee consumption (one to three years). three cups). People with a diagnosis of hypertension are included in this (high blood pressure).

Coffee and Heart Health: Arrhythmias

Consumers and health professionals have long believed that coffee can cause arrhythmias (irregular heartbeats) in people with this chronic heart condition. This idea is based on the fact that drinking coffee is associated with palpitations (skipped heartbeats).

So far there hasn’t been much evidence that caffeine can cause cardiac arrhythmias In fact, a Kaiser Permanente study found that consuming four cups of coffee daily was associated with a significant reduction in heart rate. rates of atrial fibrillation and arrhythmias. (irregular, fast heartbeat).

Coffee and Heart Health

Coffee and Heart Health: Heart Failure

People with heart failure, a condition in which the heart is less able to efficiently pump blood throughout the body, may also profit from coffee.

The more coffee people drank, the lower their chance of heart failure, according to a 2021 review of three well-known trials. One 8-ounce cup of coffee reduced the chance of heart failure by 5% to 12% in comparison to those who didn’t drink any. Two cups reduced the chance by 30%.

Drinking decaffeinated coffee had the opposite impact, increasing the risk of heart disease overall, according to the study, which was published in the journal Circulation: Heart Failure.

Coffee and Heart Health: Stroke

People who are at risk of stroke have long been urged to stay away from coffee due to the antiquated notion that coffee raises blood pressure. That guidance might also be out of date.

A review from 2014 that was included in the analysis of nearly 500,000 coffee drinkers failed to demonstrate any rise in the risk of stroke. Compared to those who drank no coffee, those who drank three cups per day had a slightly reduced risk of stroke.6

A 2013 Japanese research discovered a similar result: Over 13 years, people who drank at least one cup of coffee per day had a 20% lower risk of stroke.

Coffee and Heart Health: Coronary Artery Disease

A type of heart illness called coronary artery disease (CAD) is brought on by the accumulation of fatty deposits on the walls of arteries. These buildups, known as plaque, are made of cholesterol and other compounds that can cause atherosclerosis. (“hardening of the arteries”). Atherosclerosis and CAD are both exacerbated by hypertension and elevated cholesterol.

Coffee is believed to increase the chance of CAD because it can raise cholesterol levels. There isn’t much proof of this so far.

Higher coffee intakes were linked to a reduced risk of coronary artery disease, according to a 2014 review that was published in Circulation. A 5% lower risk of CAD was found in those who drank one to three cups of coffee per day compared to non-drinkers, according to the research, which involved over 1,275,000 participants. The risk of CAD decreased by 15% when consumption was raised to three to five cups per day.

In terms of coffee’s impact on blood cholesterol, heavy coffee drinkers may experience a rise in “bad” LDL cholesterol when consuming unfiltered coffees (such as French press and Turkish coffee). Contrarily, coffee also lowers triglyceride levels and raises “good” HDL cholesterol levels, both of which correlate to a reduced risk of heart disease.

Blood lipid levels are unaffected by coffee with a paper filter. However, if you add milk or sugar to your coffee, those advantages may be lost.

Conclusion

For a very long time, coffee has been vilified as being “bad” for your heart. Recent research suggests that this may not be the case and that coffee may lower the risk of some kinds of heart disease, including coronary artery disease and heart failure.

Contrary to popular belief, caffeine does not raise blood pressure or result in cardiac arrhythmias. (irregular heartbeats). In reality, coffee may offer protection from conditions like atherosclerosis, atrial fibrillation, and stroke.

Studies differ on the optimal amount of coffee intake, but the majority support moderate consumption. (one to three cups per day).
