Caffeine can boost energy, improve alertness and produce a general feeling of well-being - when used in moderation. Go past the sweet spot though, and that same elixir can cause insomnia, jitteriness and feelings of nervousness.
Anxious behaviour in mice was reduced after consuming Matcha powder or Matcha extract, in this study. The calming effects appear to be due to mechanisms that activate dopamine D1 receptors and serotonin 5-HT1A receptors, both of which are closely related to anxious behavior.
How does the brain process rewards? Researchers are investigating how the brain responds differently to two commonly ingested rewards - food and alcohol - to understand how they alter neural activity and behaviour.
Atypical eating behaviors may be a sign a child should be screened for autism, according to a new study.
Research finds several health warning signs that point to a person developing an eating disorder - signs that may help GPs diagnose and treat people with one of these conditions much earlier.
Once smoking was the killer health problem in Scotland. Now comes the news from Cancer Research that around 29% of adults in Scotland are obese whereas 18% of the population continues to smoke.

Micronutrient deficiencies, including vitamins B12 and D, as well as folate, iron, zinc and copper, are common in adults with celiac disease and must be addressed at that time of diagnosis, according to a new study.
In a 2018 survey, 61 percent of physicians reported having little or no training in nutrition.
Humans consuming omega-3 supplements can convert EPA (eicosapentaenoic acid) to DHA (docosahexaenoic acid), but this is only a one-way street, and no retroconversion occurs, says a new study that extends our knowledge of how we respond to supplementation.
Behaviourally defined diagnostic labels such as attention-deficit hyperactivity disorder (ADHD) seem to rarely exist in some sort of clinical vacuum. Part of that vacuum also potentially encompasses a range of somatic symptoms and/or diagnostic labels.
Mouse-based study suggests that brain cells involved in curbing overeating become less active in individuals following a high-fat diet.
Study suggests a high-fat, low-carbohydrate diet may improve brain function and memory.
Foods that have comparable nutritional profiles can have very different effects on the microbiome.
"Goat milk formula may have strong prebiotic and anti-infection properties, that could protect infants against gastrointestinal infections", researchers claim.
Fish oil supplements may ease depression in some people. Some studies in adults suggest that omega-3 fatty acids may help treat mild to moderate depression, but more research is needed.
Study suggests that certain problem behaviours in children and adolescents with autism might indicate gastrointestinal distress.
Research shows key proteins in disease can spread from gastrointestinal tract to brain
In experiments in mice, Johns Hopkins Medicine researchers say they have found additional evidence that Parkinson's disease originates among cells in the gut and travels up the body's neurons to the brain.
Study suggests that drinking coffee can stimulate 'brown fat', the body's own fat-fighting defence, which could be the key to tackling obesity and diabetes.
