People appear divided on the health benefits of coffee consumption. Some experts support its consumption, while others caution of its possible risks and health consequences. Some even question if this stimulant really lives up to its advertised benefits of increasing energy levels, improving mood or decreasing your risk for diseases like Parkinson’s, cancer and depression.

Research indicates that drinking two to three cups of coffee daily is healthy for most individuals depending on individual circumstances and diet, however researchers are discovering evidence suggesting moderate coffee intake could benefit several health conditions including Parkinson’s disease and depression. But moderation is key – any more than three cups per day could actually have negative repercussions for health.

Coffee’s best-known component is caffeine, a central nervous system stimulant that may make you more alert. But this drink also contains numerous beneficial compounds like polyphenols and chlorogenic acids which have been linked to decreased inflammation, improved insulin sensitivity, higher metabolism rates, lower cholesterol levels and better blood sugar control. Furthermore, caffeine combined with these other compounds may help combat oxidative stress by decreasing free radical levels that damage cells in your body.

Studies have demonstrated that regular coffee drinkers have lower risks of coronary heart disease, high blood pressure, Type 2 diabetes and cirrhosis (a late-stage liver condition caused by alcoholism). One 2022 study linked moderate caffeine consumption with reduced risks of death related to cardiovascular causes as well as other chronic illnesses.

Note that research on caffeine and its effects relies on observational data; other factors could have played a part in shaping results such as smoking or diet, for instance. Furthermore, not all coffee consumption studies were conducted using black coffee alone – some used milk and sugar-infused coffee beverages which added calories and fat that can negate its positive health impacts.

Coffee may help with certain health conditions such as Parkinson’s and depression; however, its consumption can lead to side effects including anxiety, jitters, headaches, stomach upset, insomnia, heartburn and diarrhea. People who already suffer from an acid reflux condition should consult with their physician prior to beginning to drink coffee regularly.

Rothschild, who enjoys two or three cups of coffee daily without sweeteners, states it is okay to continue enjoying your morning brew. However, he warns against replacing other healthy habits with coffee consumption alone such as eating well-balanced diet and regular physical activity. Furthermore, he suggests forgoing afternoon jolts as these may disrupt sleep; rather, having small protein snacks or glass of water instead may help the mind and body remain relaxed throughout the rest of your day.
