A new study from the National University of Singapore (NUS) and Fudan University in Shanghai finds a statistically significant link between drinking tea on a regular basis and lower levels of depression in older adults.
For the study, a team of researchers analyzed data provided by 13,000 people who participated in the Chinese Longitudinal Healthy Longevity Survey (CLHLS) from 2005 to 2014 and found that the benefits of tea drinking are the strongest for male participants aged 65 to 79 who live in cities and are educated, married, and receiving pensions.
Lead researcher of the study Feng Qiushi suggests an explanation: “It is likely that the benefit of tea drinking is more evident for the early stage of health deterioration. More studies are surely needed in regard to this issue.”
According to a new study from the University of Kansas, eating holiday treats that are full of added sugar can lead to metabolic, inflammatory and neurobiological processes that are associated with depressive illness.
For their study, a team of researchers analyzed a wide range of research on the physiological and psychological effects of consuming added sugar such as the Women’s Health Initiative Observational Study, the NIH-AARP Diet and Health Study, a study of Spanish university graduates, and studies of Australian and Chinese soda-drinker.
Stephen Ilardi, KU associate professor of clinical psychology, says: “When we consume sweets, they act like a drug. They have an immediate mood-elevating effect, but in high doses, they can also have a paradoxical, pernicious longer-term consequence of making mood worse, reducing well-being, elevating inflammation and causing weight gain.”
A new study in mice, conducted by the researchers from Xuzhou Medical University in China, suggests that resveratrol, a red wine compound, can be used for the treatment of depression and anxiety in the future.
In this study, the scientists used animal models and cultured mouse neurons (similar to those in the human hippocampus) to help explain the effect of the compound on rodent behaviors.
Resveratrol, which appears to reduce anxiety and depression in mice, seems to work by inhibiting PDE4D (a member of the PDE4 family that believed to be particularly important in cognition and depression) and activating cAMP (cyclic adenosine monophosphate) signaling.
Co-lead author Dr. Ying Xu, Ph.D. says: “Resveratrol may be an effective alternative to drugs for treating patients suffering from depression and anxiety disorders.”
A new study from Taiwan suggests that the use of antidepressant therapies may decrease the number of deaths by 35% in patients suffering from diabetes and depression.
For their research, the scientists used the Taiwan National Health Insurance Research Database, where they identified 53,412 individuals, of which 50,532 were taking antidepressants and 2880 people took no antidepressants.
The data showed that among the patients in the non-antidepressant group the rate of heart failure, the rate of heart failure was higher but no significant differences were detected between groups in regard to the other 3 comorbid chronic diseases.
The incidence rate of deaths events ranged from 1113.7 (95 %CI: 1078.4-1150.3) per 100,000 person-years in the highest group to 1963.7 (95%CI: 1876.8-2054.7) per 100,000 person-years in the lowest group. Researchers noted that the rates of death decreased as the total cumulative dose increased.
A new study from the Hellenic Open University in Patra, Greece, finds a link between consuming products of the Mediterranean diet and lower risk of depression.
For the study, a team of researchers used data received from members of day-care centers for senior people in the East Attica region in Greece. Among the participants, 64 percent moderately adhered to the mentioned diet and 34 percent highly adhered to the diet.
Having analyzed the received data, the scientists found that participants with higher adherence to the Mediterranean-type diets, especially those who ate more vegetables, less poultry, and drank less alcohol, showed a lower probability of developing depression or depression symptoms.
Study authors note in their paper: “Our results support that depression in older adults is common and strongly associated with several risk factors.”
