Dietary Guidelines Released

Yesterday, the Department of Health and Human Services released the 2015-2020 Dietary Guidelines which are utilized to encourage Americans to eat a healthier diet. Importantly, the guidelines encourage Americans to consume less than 10% of calories per day from added sugars. The report states:

“Although the evidence for added sugars and health outcomes is still developing, the recommendation to limit calories from added sugars is consistent with research examining eating patterns and health. Strong evidence from mostly prospective cohort studies but also randomized controlled trials has shown that eating patterns that include lower intake of sources of added sugars are associated with reduced risk of CVD in adults, and moderate evidence indicates that these eating patterns are associated with reduced risk of obesity, type 2 diabetes, and some types of cancer in adults. As described earlier, eating patterns consist of multiple, interacting food components, and the relationships to health exist for the overall eating pattern, not necessarily to an isolated aspect of the diet. Moderate evidence indicates a relationship between added sugars and dental caries in children and adults.”
The American Association for Dental Research submitted comments to the Advisory Committee last spring supportive of reducing the intake of free sugars and drawing attention to the relationship between sugar intake and dental caries. AADR is pleased this focus has remained in the final Dietary Guidelines.

AADR Submits Comments on the Common Rule

Earlier this week, AADR submitted comments Notice of Proposed Rulemaking (NPRM), “Federal Policy for the Protection of Human Subjects,” better known as the Common Rule. The NPRM proposes to extend the definition of human subject research to include: obtaining, use, study or analysis of biospecimens regardless of identifiability. The NPRM also specifies that broad consent should be obtained for future unspecified research as opposed to obtaining consent for each specific study. AADR strongly encouraged the Department of Health and Human Services to include a definition for biospecimens and under what circumstances certain types of secondary use research would be exempt. We expressed our concern about the impact this rule would have on research involving samples collected for clinical purposes, either surgical waste or for diagnostic purposes and strongly encouraged the exemption of extracted teeth and mineralized tissues of the teeth from the definition of biospecimen and human subject research. AADR also weighed in on other topic areas including the costs, ten year time limit for biospecimens and how to obtain broad consent.

AADR Submits Comments on NTP Review of Fluoride and Developmental Toxicity

Last month, AADR submitted comments on the National Toxicology Program Board of Scientific Counselors proposed systematic review of fluoride and developmental toxicity. AADR encouraged NTP to focus on the therapeutic range of water fluoridation up to limits set by the Environmental Protection Agency. We also stated that, “Authoritative reviews confirm the safety and efficacy of water fluoridation to improve population oral health and clearly demonstrate that the best available science-based evidence does not establish a causal relationship between lowered intelligence (IQ) in children, behavioral disorders, or central nervous system disorders and consumption of water fluoridated at recommended levels and use of fluoride dental products.” AADR also indicated that we do not believe quality systematic reviews on the neurotoxicity of fluoride at therapeutic levels exists. Thus, we encouraged the National Toxicology Program to affirm the safety and effectiveness of fluoride and acknowledge the longstanding and significant role fluoride has played in improving the oral health of Americans for seven decades.
