According to a new research from Cornell University, caffeine may reduce people’s perception of sugar leading to eating more sweet treats.
For the research, a team of scientists analyzed data received from 107 volunteers that were randomly divided into two groups. The first group received a decaffeinated coffee with a 200 mg caffeine supplement. Another group was given decaffeinated a coffee with an added substance making its taste as bitter as the taste of regular coffee.
Professor Robin Dando says: “When you drink caffeinated coffee, it will change how you perceive taste — for however long that effect lasts. So if you eat food directly after drinking a caffeinated coffee or other caffeinated drinks, you will likely perceive food differently.”
According to a new study by the team at Huazhong University of Science and Technology, drinking coffee can really help in combating obesity by burning calories due to its ability to release oxytocin, a hormone that affects both appetite and metabolism.
For the study, the researchers followed overweight mice who were given high amounts of caffeine. It helped them eat less and be more active on a wheel running machine.
Lead author of the study Prof. Guo Zhang says: “We found caffeine significantly reduced the food intakes and increased the wheel-running activities of diet-induced obese mice. Together, the results demonstrate caffeine treatment ameliorates obesity through both the reduction of food intake and the promotion of energy expenditure.”
A recent research finds that eating a Mediterranean diet and drinking coffee may lower the risk of developing age-related eye disease (age-related macular degeneration, or AMD), one of the leading causes of blindness.
In the study, 883 people aged 55 and older participated in the study. The researchers assessed their diets with the help of questionnaires. 449 people had early stage of AMD and 434 didn’t have eye disease. Following Mediterranean diet was associated with a 35% lower risk of AMD.
Also, the researchers found that people who consumed high level of caffeine seemed to have a lower risk of AMD. Among those who consumed high levels of caffeine (around 78mg of coffee per day, or one shot of espresso), 54% did not have AMD and 45% had the disease.
A clinical study, recently published in the journal Parkinsonism and Related Disorders, presents that patients with Parkinson’s disease who were drinking coffee oftener showed a reduced need for standard medical treatment.
In this four-year study, the scientists from the United Kingdom and Italy investigated the clinical association of caffeine consumption among newly diagnosed Parkinson’s disease. They looked at the effects of a broad range of products which contain caffeine, including energy drinks and chocolate.
In the research, people who had an extra cup of coffee daily were more likely associated with less severe symptoms of the disease.
The study concluded that higher caffeine consumption was associated with a reduced accrual of both motor and non-motor disability.
