“Bottled water can contain very small plastic particles. Using stimulated Raman scattering microscopy, researchers identified roughly 240,000 detectable plastic particles per liter on average across three popular bottled-water brands, most of them nanoplastics.”

“If your magnesium levels are inadequate, then your ability to boost mitochondrial number during HIT will be dampened, thus, compromising performance and the mitochondrial mass you would have otherwise gained as a consequence of your hard work and effort.”

“Rumination, the practice of dwelling on external stressors to excess, can set in motion a cascade of hormonal and physiological responses that harm mental and physical health. Meditation has been shown to reduce rumination and its negative effects, however, and influences the gene expression of as many as 500 genes, many of which are in the brain.”

“Using a Mendelian randomization analysis, scientists determined that people carrying genetic variants associated with low vitamin D levels have higher mortality from respiratory tract infections and higher all-cause mortality.”

“The gut-brain axis, the bidirectional signaling pathway between the gastrointestinal tract and the nervous system, modulates the body's stress response. A key player in this pathway is the gut microbiome, the collection of genomes of the microorganisms that exist in the gastrointestinal tract.”

“A pooled analysis estimated effects of about 0.07 standard deviation for global cognition and 0.06 for episodic memory, providing evidence that a standard multivitamin can support selected cognitive outcomes in some older adults.”

“More than a century of research has demonstrated that nicotinamide adenine dinucleotide (NAD+) is an indispensable mediator of vital metabolic and physiological processes, including energy production, DNA synthesis and repair, and regulation of gene expression – across multiple species.”

“Omega-6 fatty acids are found in vegetable oils and nuts, whereas omega-3 fatty acids are primarily found in fatty fish. Although older studies showed that the ratio of omega-6s to omega-3s in blood were cause for concern, Dr. Harris explains that those concerns are likely unfounded.”

“Protein blending is another practical strategy. A trial comparing an equivalent dose of a corn, pea, and canola blend with milk protein found no difference in post-meal muscle protein synthesis in healthy young men.”

“In a controlled crossover study of eight healthy men, a high-PPO banana smoothie produced an 84% lower peak concentration of circulating flavan-3-ol metabolites than a flavan-3-ol capsule.”
