“Intake of Raw Fruits and Vegetables Is Associated With Better Mental Health Than Intake of Processed Fruits and Vegetables” reports on a study using an online survey of 422 young adults in New Zealand and the US. Raw Fruit and Vegetable Intake (RVI) was compared to processed (cooked and canned veggies) FVI using several mental health-related measures. Raw FVI was found to significantly predict higher mental health outcomes. The authors review studies of diet and mood, and theorize that their findings fit with evidence that cooking reduces some important nutrients in veggies, and these nutrients contribute to positive mental health.
“Evaluation and Treatment of Depression May Reverse Memory and Cognitive Difficulties in Older Adults with Mild Cognitive Impairment” reviews interesting research which found that older individuals with worse depression and mood symptoms are more likely to develop mild cognitive impairment (MCI), and to progress from MCI to dementia. The worse the symptoms of depression and mood disorder, the more likely the progression from MCI to dementia.
No ‘far transfer’ – chess, memory training and music does make you better at chess, memory training and music” discusses a review of several meta-analytic studies assessing the evidence for “far transfer” learning – the theory that training in one brain domain transfers to another domain. Or, does learning to ride a BMX bicycle result in better skills are riding a unicycle, or piloting a helicopter? The article concludes: “Limiting the analysis to the best-designed studies, they found little or no evidence of far-transfer. The only exception was a robust effect of working memory training on other memory tasks, which
“Brain activity can predict success of depression treatment”reports on a study to be published by JAMA Psychiatry in the June 28 edition. The study builds on previous studies, which have identified neurological markers that predict how patients will respond to antidepressant medication. The study identified more specific markers. The authors conclude that for patients with the marker of low response, “clinicians could decide to start with more aggressive treatment at the outset, such as a combination of pharmacology and psychotherapy, and importantly, monitor these patients more closely.” From ScienceDaily, read the original article.
Associations of Bariatric Surgery with Changes in Interpersonal Relationship Status: Results From 2 Swedish Cohort Studies finds it bariatric surgery is associated with both increased incidence of divorce/separation and marriage/new relationship. The study had 2,010 participants, and a matched (obesity) control group. The surgery group had twice the incidence of marriage/new relationship after surgery compared with controls. Those with the best outcome from surgery had a higher incidence of marriage/new relationship outcomes. After four years, the cumulative incidence of divorce/separation was almost twice as high for the surgery group as for the control group. The authors theorize that the incidence
