20 May 2019 --- A new study shows that 61 percent of US consumers are concerned about the products they put in and on their bodies, but 34 percent say they rarely or never research product claims. Almost half (46 percent) of participants say they have purchased a product despite being unsure of the validity of its claims, while the majority of millennials are concerned about potentially harmful food. These are the main findings of an online survey conducted on behalf of NSF International, an independent public health and safety organization in the US. The organization says the findings underscore the need for independent third-party certification of food, dietary supplements and personal care products.
