Brain function differs in obese children and mindfulness may help.

1 Feb

A paper in the journal Heliyon titled: “Imbalance in resting state functional connectivity is associated with eating behaviors and adiposity in children.”

The authors write:

“We hypothesized that unhealthy eating habits and adiposity among children are associated with functional connectivity between brain regions associated with impulsivity, response inhibition, and reward.”

You can find a good summary here.

One interesting note:

“Our results indicate the importance of identifying children at risk for obesity for earlier intervention. In addition to changing eating habits and physical activity, strategies that normalize neural functional connectivity imbalance are needed to maintain healthy weight. Mindfulness may be one such approach as it is associated with increased response inhibition and decreased impulsivity.”

Coffee enhances memory consolidation

16 Dec

Consistent with previous research, a study published in Nature Neuroscience reports that caffeine enhances memory consolidation.

“We used post-study caffeine administration to test its effect on memory consolidation using a behavioral discrimination task. Caffeine enhanced performance 24 h after administration according to an inverted U-shaped dose-response curve; this effect was specific to consolidation and not retrieval. We conclude that caffeine enhanced consolidation of long-term memories in humans.”

 

International differences Alzheimer’s disease

18 Nov

A post by Dr. Greger explores international differences in Alzheimer’s disease:

“The rates of dementia differ greatly around the world, from the lowest rates in Africa, India, and South Asia, to the highest rates in Western Europe and especially North America. Is it all just genetics? Well, the incidence of dementia and Alzheimer’s disease is significantly lower for Africans in Nigeria than for African Americans in Indianapolis, for example—up to five times lower.”

He notes that:

“Alzheimer’s rates of Japanese-Americans living in the U.S. are closer to that of Americans than to Japanese. When people move from their homeland to the United States, Alzheimer’s rates can increase dramatically. Therefore, when Africans or Asians live in the United States and adopt a Western diet, their increase in Alzheimer’s risk suggests that it’s not genetics.”

Can diets improve mood and productivity?

23 Sep

Dr. Greger reports:

“The most comprehensive controlled trial of diet and mood finds that a plant-based nutrition program in a workplace setting across ten corporate sites significantly improves depression, anxiety, and productivity.”
