TL;DR: Krill oil has a slight edge for inflammation due to astaxanthin, but fish oil wins for raising blood omega-3 levels and long-term cardiovascular outcomes. Fish oil has dominated the omega-3 supplement market for decades. But a smaller crustacean from Antarctic waters is making a quiet challenge: krill oil. Marketing claims abound—krill oil is more …
TL;DR: A comprehensive review of the UK Biobank found that fish oil supplements show favorable associations with health outcomes—not harmful ones—contradicting recent alarming headlines about atrial fibrillation risk. When a major study claims fish oil supplements increase heart arrhythmia risk, the headlines scream. But what happens when researchers dig deeper into the same dataset and …
TL;DR: Obesity and depression form a pathophysiological trap: inflammatory cytokines and dysbiotic bacteria from obesity trigger neuroinflammation and mood disruption, while depression’s behavioral changes and HPA axis dysfunction worsen obesity. Obesity and depression are twin epidemics in the modern world, and they’re not independent. People with obesity are 1.5 to 2 times more likely to …
TL;DR: Dysbiotic bacteria in depressed adolescents cannot synthesize lysine and tryptophan, starving the brain of amino acids needed for glutamate transport and serotonin production—a causative link proven by transplanting dysbiotic bacteria into healthy rats. Depression in adolescents has tripled in the past two decades. Most treatments target a single neurotransmitter—serotonin. But a landmark multi-omics study …
TLDR: Lower serum vitamin D levels are associated with an increased risk of stroke, particularly ischemic stroke, and are linked to poorer stroke outcomes. Highlights: The meta-analysis included 27 studies with 45,302 participants, finding a combined relative risk (RR) of 1.28 for stroke risk associated with low vitamin D levels. A lower level of serum …
TLDR: This study provides evidence that high salt intake is causally associated with an increased risk of developing dementia, including Alzheimer’s disease (AD) and undefined dementia. Highlights: Causal Association: High salt intake is significantly associated with an increased risk of any dementia (OR = 1.73) and specifically Alzheimer’s disease (OR = 2.10). Cognitive Performance: Higher …
Eating foods rich in certain flavonoids may help lower the risk of experiencing depressive symptoms, suggests new research based on U.S. national health data. Key facts: Higher intakes of anthocyanidins, flavanones, flavones, and isoflavones were associated with lower odds of depressive symptoms after adjusting for confounders. There was an inverse association between total flavonoid intake …
Food provides the building blocks for our mental and physical health. New research reveals that many common foods supply key neurotransmitters that regulate brain and nervous system function. Understanding how our diet provides these crucial molecules opens up possibilities for supporting brain health through food. Key Facts: Foods contain the same neurotransmitters used by the …
Researchers have uncovered new insights into how fasting alters dopamine signaling in the brain’s reward circuitry. Their findings, published in the Journal of Neurophysiology, suggest that fasted mice exhibit enhanced dopamine release in the ventral tegmental area (VTA) of the brain compared to fed mice. This may help explain fasting’s impact on motivation and reward-seeking …
Insects are increasingly being recognized as a nutritious and eco-friendly alternative protein source that could help feed the world’s growing population. Recent research highlights the nutritional benefits of insects, their potential use as food ingredients, health-promoting bioactive compounds, impact of processing, barriers to adoption, and considerations around safety and regulation. Key Facts: Over 2,000 insect …
