Sunscreen with Zinc Oxide May Become Toxic with Sunlight
Razi Berry Sunscreen that includes zinc oxide, a common ingredient, loses much of its effectiveness and becomes toxic after two hours of exposure to ultraviolet radiation, according to a collaboration that included Oregon State University scientists. The toxicity analysis involved zebrafish, which share a remarkable similarity to humans at the molecular, genetic and cellular levels, […]
Shape of Nanomaterials Impact Ability to Cross Blood Brain Barrier
Razi Berry Nanomaterials found in consumer and health-care products can pass from the bloodstream to the brain side of a blood-brain barrier model with varying ease depending on their shape — creating potential neurological impacts that could be both positive and negative, a new study reveals. Scientists found that metal-based nanomaterials such as silver and […]
Food Packaging May Inhibit Nutrient Absorption
Node Smith, ND A recent article was published that supports staying away from processed foods – and even canned foods.1 Apparently, a common substance used in the lining of certain canned foods may be negatively affecting the absorption of nutrients in the intestine. The chemical compound may be surprising: Zinc Oxide. Zinc Oxide (ZnO) Zinc […]
