Some nutrition scientists and much of the public often consider epidemiologic associations of nutritional factors to represent causal effects that can inform public health policy and guidelines. However, the emerging picture of nutritional epidemiology is difficult to reconcile with good scientific principles. The field needs radical reform. In recent updated meta-analyses of prospective cohort studies, almost all foods revealed statistically significant associations with mortality risk.1… 
Nutritional epidemiology and cancer: A Tale of Two Cities
Though important questions remain, the understanding of nutrition and cancer over the life course is coherent and has been informed by nutritional epidemiology and other data.

Challenges of human nutrition research
Facilities to house and feed subjects could increase rigor and advance nutrition science Nutrition is fundamentally important for human health (1), but there is widespread public confusion about what
Dietary Adherence in a Clinical Trial of a Nutritional and Behavioral Intervention.
In this issue of JAMA, a large-scale clinical trial from Spain, conducted by a collaborative group known as the PREDIMEDPlus consortium, reports interim results of a long-term study of patients with metabolic syndrome, with primary outcome the reported adherence to an energy-restricted Mediterranean diet.
Nutritional epidemiology, extinction or evolution? It is all about balance and moderation
In this issue of the European Journal of Epidemiology, Giovannucci contradicts the arguments of Ioannidis by stating that current methodologies such as food frequency questionnaires and hypothesis-based approaches are sufficient to overcome the complexity of diet and deal sufficiently with confounding, and that considerable RCT data link common dietary factors to risk factors for major diseases.
Children and adults should avoid consuming animal products to reduce the risk for chronic disease: Debate Consensus.
Opposition views regarding the role of animal products in human diets were outlined and points of agreement and controversy were identified, as well as opportunities for further studies.
Food for Thought or Feeding a Dogma? Diet and Coronary Artery Disease: a Clinician’s Perspective
An overview of nutrition studies evaluating the association of dietary saturated fat and meat intake with the development of coronary artery disease (CAD) and implications of recent data are provided and the challenges with RCTs are considered.
A Systematic Review of Ecological Momentary Assessment of Diet: Implications and Perspectives for Nutritional Epidemiology
A systematic review of EMA methods for the assessment of dietary intake in epidemiological studies pointed out that EMA can be applied in various fields of nutritional epidemiology, from the identification of determinants of dietary habits in healthy people to the management of patients with eating or metabolic disorders.
Estimating the effect of nutritional interventions using observational data: the American Heart Association's 2020 Dietary Goals and mortality.
It is estimated that adherence to the food-based AHA 2020 Dietary Goals starting in midlife may reduce the 20-y risk of mortality.


Food groups and risk of all-cause mortality: a systematic review and meta-analysis of prospective studies.
Selecting specific optimal intakes of the investigated food groups can lead to a considerable change in the risk of premature death, whereas consumption of risk-increasing foods is associated with a 2-fold increased risk of all-cause mortality.
Dietary, circulating beta-carotene and risk of all-cause mortality: a meta-analysis from prospective studies
Dietary or circulating beta-carotene was inversely associated with risk of all-cause mortality, according to a comprehensive search on publications of PubMed and EMBASE up to 31 March 2016.
Perspective: Limiting Dependence on Nonrandomized Studies and Improving Randomized Trials in Human Nutrition Research: Why and How.
An improved randomized agenda may clarify many things in nutrition science that might never be answered credibly with nonrandomized observational designs, such as dietary measurement error and selective reporting.
Primary Prevention of Cardiovascular Disease with a Mediterranean Diet Supplemented with Extra‐Virgin Olive Oil or Nuts
In this study involving persons at high cardiovascular risk, the incidence of major cardiovascular events was lower among those assigned to a Mediterranean diet supplemented with extra‐virgin olive oil or nuts than among those assign to a reduced‐fat diet.
Validity of U.S. Nutritional Surveillance: National Health and Nutrition Examination Survey Caloric Energy Intake Data, 1971–2010
The confluence of results and other methodological limitations suggest that the ability to estimate population trends in caloric intake and generate empirically supported public policy relevant to diet-health relationships from U.S. nutritional surveillance is extremely limited.
Coffee Drinking and Mortality in 10 European Countries: A Multinational Cohort Study.
Coffee drinking was associated with reduced risk for death from various causes and this relationship did not vary by country.
Coffee consumption and health: umbrella review of meta-analyses of multiple health outcomes
Coffee consumption seems generally safe within usual levels of intake, with summary estimates indicating largest risk reduction for various health outcomes at three to four cups a day, and more likely to benefit health than harm.
Implausible results in human nutrition research
Definitive solutions won’t come from another million observational papers or small randomized trials, but they can come from a handful of simple experiments.
