Book excerpt: Policy and practice in nutrition and dietetics is based on current available scientific evidence. However, the discipline faces an increasing volume of misinformation and pseudo-science relating to nutrition. This presents a challenge to the nutrition research community and practitioners alike, as well as consumers. It highlights the need to critically examine the current evidence-based framework in nutrition, and identify strategies for future improvements. We describe the use of systematic reviews as part of the current evidence-based framework in the nutrition field, and discuss challenges and opportunities relating to policy and guideline development. Undertaking systematic reviews is part of the methodology underpinning the evidence-based framework. These reviews form the basis for implementation documents in public health such as dietary guidelines and nutrient reference values. Assuring the quality of systematic reviews is an important priority. Recommendations for practitioners and consumers emerge following these reviews on consumption of nutrients, foods, and whole diets; however an ongoing challenge is ensuring these resources are updated regularly to remain timely and accurate. Another application of systematic reviews is for substantiation of health claims made on food packaging and other forms of nutrition related messaging. These may support the marketing of food products, so it is important to evaluate the strength and quality of the evidence that supports these claims. In this case, a lack of external oversight of self-substantiation of claims may increase the risk that claims are misused or are inaccurate. Collecting, synthesizing, and translating the evidence base in nutrition remains an imperative task for those working in the food and nutrition domain. This is particularly seen in light of the increasing volume of misinformation encountered by consumers and the growing problem of lifestyle related disease associated with poor diet. Nutrition researchers, policy makers and practitioners need to work together effectively to ensure timely, efficient, and relevant collection, synthesis, and implementation of the evidence base. To ensure informed and robust nutrition policy, research, and practice into the future, consistent and rigorous approaches to systematic review, regular updates and effective oversight is required.Conflict of interest:There is no conflict of interest.
