Caffeine

TUESDAY, Sept. 17, 2024 -- A few cups of coffee each morning can help protect a person against heart disease, stroke and type 2 diabetes, a new study says. Drinking three cups of coffee a day -- or about 200 to 300 milligrams of caffeine -- lowered the risk of health problems linked to the heart or metabolism, researchers found. “The findings highlight that promoting moderate amounts of coffee or caffeine intake as a dietary habit to healthy people might have far-reaching benefits,” said lead researcher Dr. Chaofu Ke , a medical statistician with Suzhou Medical College of Soochow University in China. For the study, researchers analyzed data on more than 500,000 people ages 37 to 73 participating in the long-term U.K. Biobank research project. Out of that group, they identified more than 172,000 people who’d reported their caffeine intake, and another 188,000 who’d reported their coffee or tea consumption. The researchers compared people’s caffeine intake to whether they had developed two or more signs of cardiometabolic disease . That term relates to risk factors that can harm heart health, such as diabetes, high cholesterol, high blood pressure and excess body weight. Results showed that any level of coffee or caffeine intake lowered a person’s risk of suffering multiple health problems related to heart or metabolism. But the best results came with moderate intake of coffee or caffeine, they found. People who drank three cups of coffee a day had a 48% lower risk of heart or metabolic disease, compared to those who drank no coffee. And those who got 200 to 300 milligrams of caffeine daily had a 41% reduced risk compared to those who consumed none or less than 100 milligrams, researchers found. The new study was published Sept. 17 in the Journal of Clinical Endocrinology & Metabolism . Any lower risk would help protect a person’s health, as people with heart or metabolic diseases are four to seven times more likely to die from any cause, researchers said in a journal news release. They also have higher risk of disability and mental stress. Whatever your topic of interest, subscribe to our newsletters to get the best of Drugs.com in your inbox.

FRIDAY, Aug. 30, 2024 -- Long-term, daily intake of high levels of caffeine impacts recovery of heart rate and blood pressure following physical exertion, according to a study presented at ACC Asia 2024, the joint meeting of the American College of Cardiology and the Cardiological Society of India, held from Aug. 16 to 18 in Delhi, India. Nency Kagathara, M.B.B.S., from Zydus Medical College and Hospital in Dahod, India, and colleagues assessed the effects of long-term caffeine consumption on recovery of heart rate and blood pressure. The analysis included 92 normotensive, healthy individuals aged 18 to 45 years. The researchers found that 19.6 percent of participants consumed >400 mg of caffeine daily. Higher daily caffeine intake (>400 mg) was more common among women, individuals employed in business and management roles, and those living in urban areas. Following the three-minute step test, significantly elevated heart rates (100/minute) and blood pressures (>140/90 mm Hg) were seen after five minutes of rest in participants who consumed >600 mg of caffeine daily. "Due to its effect on the autonomic nervous system, regular caffeine consumption could put otherwise healthy individuals at risk of hypertension and other cardiovascular events," Kagathara said in a statement. "Increasing awareness of these risks is vital to improve heart health for all."
