Coffee is undoubtedly one of the most popular beverages in the world. Some people find the smell and taste of coffee addictive. Research reveals that there are around 1,000 antioxidants in unprocessed coffee beans, which is way more than what is present in cocoa and green tea. The caffeine present in coffee stimulates the central nervous system, making people more alert.
Equally, there has been a constant debate over the effects of coffee on heart health. While some research suggests that coffee helps in maintaining the health of the heart and blood vessels, others indicate that excess coffee consumption can increase the risk of cardiovascular events such as a heart attack or stroke.

Several sources, like the FDA, Mayoclinic and others have said that for healthy adults, up to 400 milligrams (mg) per day is a safe amount which will not cause side effects. This translates to roughly 4 cups of brewed coffee. However, it must be noted that this dose may vary for pregnant and lactating women or those with existing heart conditions.
Coffee must not be consumed before bedtime as caffeine can stay in the bloodstream for 6 hours after drinking and can hinder a sound sleep. It is also advised that pure and highly concentrated caffeine products must be avoided to maintain better heart health.
Excess consumption of coffee can make one feel jittery, anxious and dizzy. The other side effects of drinking too much coffee include:
Studies have found a direct link between drinking coffee and coronary heart disease. However, various other studies claim that coffee is healthy for the heart. To avoid any negative effects of coffee, it must be consumed in the right amount. People with previously diagnosed heart condition must consider reducing their coffee consumption or switching to decaffeinated coffee.
