New studies pursue the ‘perfect’ blend for coffee and health

In the morning, many individuals consume one or two cups of coffee, feeling refreshed and ready to tackle the day. Some may have an additional cup at work, while others prefer to include chicory in their brew. Coffee is prepared using a filter, often with milk and sugar added for flavor. In the United States and Europe, coffee consumption is prevalent, with people drinking more of it daily.

However, concerns arise regarding the impact of coffee consumption on health. Questions emerge about the ideal number of cups consumed per day, whether black coffee is preferable or if milk and sugar are acceptable additions, and how this affects overall well-being.

The American Heart Association recently published a statement on caffeine and cardiovascular disease, aiming to clarify existing ambiguities. Researchers examined numerous studies focusing on caffeine, the active compound in coffee, which energizes the brain and central nervous system and stimulates energy production and utilization in the body.

The statement suggests that moderate caffeine consumption, primarily through coffee, may reduce the risk of type-2 diabetes, stroke, heart failure, and atrial fibrillation. Conversely, excessive caffeine intake, particularly from energy drinks, may negatively impact cardiovascular health. Additionally, unfiltered coffee could increase LDL cholesterol levels.

Data from the Nurses' Health Study at Harvard T.H. Chan School of Public Health and Harvard Medical School, along with an analysis of 3 million people from the U.K. Biobank and Health Canada, indicate that consuming four cups daily may lower the likelihood of developing cancer, type-2 diabetes, heart diseases, and age-related disorders like dementia and Alzheimer's.

Nevertheless, pregnant and breastfeeding women are advised to limit their coffee intake to three cups per day. The Journal of Agricultural and Food Science published a 2023 analysis from Copenhagen, Denmark, recommending hot black coffee with minimal additives like sugar or milk. However, adding milk to black coffee is beneficial, as it provides antioxidants, minerals, and vitamins, mitigating the coffee's bitterness.

In South India, many prefer pure coffee, which contains no caffeine but the polysaccharide inulin, known for supporting digestion and blood sugar regulation. A review published in the Journal of Food Science and Technology by researcher Pushpa S. Murthy discusses the benefits of blending coffee with chicory. Chicory, a herb with colored flowers, contains no caffeine but inulin, which aids digestion and may help control blood sugar.

Incorporating chicory into coffee enhances its fragrance and taste. The ideal balance between coffee and chicory is suggested to be 70:30 or 60:40, coffee to chicory, to achieve a harmonious taste and health benefits. Most coffee vendors in India adhere to these ratios unless customers request 'pure' coffee. This writer, too, favored pure coffee until reading the review by the Mysuru group.
