Brain serotonin is crucially involved in regulating mood, social behavior, and physical health. While medications that alter serotonin levels have revolutionized psychiatry, non-drug approaches may provide safer, sustainable ways to optimize serotonin and promote wellbeing. Key Facts: Brain serotonin influences mood, sociability, and health in animals and humans. Higher serotonin is linked to positive mood, …
A systematic review and meta-analysis published in Scientific Reports evaluated the potential association between chronic fluoride exposure and neurological damage. The study aimed to analyze the impact of fluoride from different sources on neurological disorders in humans. After a thorough literature search, the authors included 27 observational studies in the qualitative analysis. The results showed …
Suicide is a major global public health problem, accounting for over 800,000 deaths worldwide each year. Lithium, a mood stabilizing medication, has been proposed as a novel population-level suicide prevention strategy through supplementation of trace doses into the public drinking water supply. This controversial idea has sparked much debate around its ethics, risks, benefits and …
A new review of research finds strong evidence that fluoride exposure, especially during fetal development and infancy, can lead to decreased IQ and other neurotoxic effects. While fluoride may help prevent dental cavities when applied topically, ingesting elevated levels early in life appears to pose risks to long-term brain health. Key facts: Multiple recent studies …
Microplastics, the tiny plastic fragments less than 5mm in size, are increasingly being found everywhere – in the oceans, freshwater systems, soil, air, and even in our food. As these tiny plastic pieces spread unabated into the environment, scientists are concerned about their effects on human health. Key facts: Over 6,000,000 tons of microplastics are …
A new systematic review published in BMC Geriatrics suggests that supplementing with medium-chain triglycerides (MCTs) may provide cognitive benefits for older adults without dementia. MCTs are a type of fatty acid found in foods like coconut oil and palm kernel oil that may help provide the brain with an alternative energy source. Key Facts: MCT …
Aspartame is one of the most widely used artificial sweeteners in the world, but there are conflicting views on its safety and health effects. Key Facts: Aspartame is about 200 times sweeter than sugar but contains minimal calories. It is commonly used in diet sodas and other sugar-free products. When digested, aspartame breaks down into …
Aspartame is an artificial sweetener found in over 6,000 food products. While it provides a sweet taste without calories, emerging research suggests aspartame may negatively impact brain health and function. Key Facts: Aspartame is made up of phenylalanine, aspartic acid, and methanol. High levels of these metabolites may cause neurophysiological issues. Studies link aspartame to …
A new study published in PLOS Medicine has found associations between consumption of artificial sweeteners, particularly aspartame and acesulfame potassium, and increased risk of overall cancer as well as breast and obesity-related cancers. Key findings: Higher consumers of artificial sweeteners had a 13% increased risk of overall cancer compared to non-consumers. Aspartame intake was associated …
