“Personal-care and cleaning products can be potential sources of phthalates and other plastic-associated chemicals through skin contact or inhalation, but these chemical exposures are not the same as exposure to microplastic particles.”

“Multivitamins appear to have no effect on total cancer incidence or several types of cancers including breast, colorectal, prostate, or skin (melanoma), although the risk of lung cancer was 38% *lower for participants taking a multivitamin.”

“In contrast to subcutaneous fat, located under the skin, visceral fat plays a central role in the interrelationship between obesity and systemic inflammation through its secretion of proinflammatory cytokines.”

“Urine collection is often incomplete, undercounting nitrogen losses. We lose nitrogen through sweat, feces, skin, and breath—which aren't fully captured. Different foods have different nitrogen to protein ratios, adding noise to the system.”

“The body can make vitamin D3 in skin exposed to UVB light, but synthesis varies with season, latitude, time of day, skin pigmentation, sunscreen use, and age. Serum 25-hydroxyvitamin D is the standard marker used to assess vitamin D status.”

“However, when insulin levels fall after weight loss, better nutrition, and exercise, these skin conditions regress or reverse completely. The Connection Between Insulin Resistance and Chronic Disease Because insulin affects nearly every organ and tissue, imbalances can have widespread effects.”

“As other cell types (e.g., skin cells, muscle cells, nerves) regenerate, fibroblasts must be cleared away to allow space for them to grow. This process of rapid expansion followed by programmed senescence and clearance is necessary for quick healing without increasing cancer risk.”

“Since ultraviolet light is required for vitamin D synthesis, reduced exposure to the sun or having dark-colored skin impairs vitamin D production. Approximately 70 percent of people living in the United States are vitamin D insufficient and ~30 percent are deficient.”

“Resveratrol is a natural compound found primarily in the skin of red grapes and the root of Polygonum cuspidatum (also known as Japanese knotweed). It is also present to a lesser degree in peanuts and blueberries.”
