Coffee contains the antioxidants chlorogenic acid and cafestol, which reduce inflammation and help prevent cardiovascular diseases and cancer. Dr. Chang Chin-Chien, a renowned Taiwanese breast cancer specialist and author of “A Cup of Coffee Fights All Diseases,” outlined the health benefits of coffee and shared the best ways to drink it.
Coffee Benefits 11 Health Conditions
Coffee improves or fights the following 11 conditions.
1. Type 2 Diabetes
Research has found a strong correlation between habitual coffee consumption and a lower risk of Type 2 diabetes. Researchers explain that regularly drinking coffee can help protect liver and beta-cell function during the chronic metabolic stress phase that occurs before the onset of overt diabetes, thereby lowering the risk of developing it.
2. High Blood Pressure
Dr. Chang noted that initially, drinking coffee may lead to higher blood pressure. However, with habitual consumption, it can actually lower it.
A meta-analysis published in 2023 involving 25 studies with 463,973 participants found a negative association between coffee consumption and the risk of high blood pressure. One of the studies indicated that nonsmoking men and women who drank three to four cups of coffee per day had a lower risk of developing high blood pressure, while no significant association was found among smokers.
3. Cardiovascular Diseases
Coffee is beneficial for cardiovascular health. A study published in the European Journal of Preventive Cardiology conducted a 12 1/2-year follow-up on 449,563 participants with a median age of 58. The results showed that compared to noncoffee drinkers, individuals who consumed ground, instant, or decaffeinated coffee had a reduced risk of cardiovascular events and all-cause mortality, with the greatest effects seen in those who drank two to three cups of coffee per day. Additionally, the researchers found that both ground coffee and instant coffee were associated with a reduced risk of arrhythmias, while decaffeinated coffee showed no such association.
4. Periodontal Disease
Chronic inflammation of the periodontal tissues can lead to gum recession, alveolar bone loss and, eventually, tooth loss. A systematic review highlighted that daily coffee consumption may help prevent alveolar bone loss. Coffee contains various components with antioxidant and anti-inflammatory properties, including caffeine, chlorogenic acid, and caffeic acid. Furthermore, chlorogenic acid acts as an antimicrobial agent, which plays a role in combating periodontal disease. However, some studies have indicated a negative correlation between coffee consumption and periodontal health.
