ABSTRACT Background Diet affects the human gastrointestinal microbiota. Blood and urine samples have been used to determine nutritional biomarkers. However, there is a dearth of knowledge on the utility of fecal biomarkers, including microbes, as biomarkers of food intake. Objectives This study aimed to identify a compact set of fecal microbial biomarkers of food intake with high predictive accuracy. Methods Data were aggregated from 5 controlled feeding studies in metabolically healthy adults (n = 285; 21–75 y; BMI 19–59 kg/m2; 340 data observations) that studied the impact of specific foods (almonds, avocados, broccoli, walnuts, and whole-grain barley and whole-grain oats) on the human gastrointestinal microbiota. Fecal DNA was sequenced using 16S ribosomal RNA gene sequencing. Marginal screening was performed on all species-level taxa to examine the differences between the 6 foods and their respective controls. The top 20 species were selected and pooled together to predict study food consumption using a random forest model and out-of-bag estimation. The number of taxa was further decreased based on variable importance scores to determine the most compact, yet accurate feature set. Results Using the change in relative abundance of the 22 taxa remaining after feature selection, the overall model classification accuracy of all 6 foods was 70%. Collapsing barley and oats into 1 grains category increased the model accuracy to 77% with 23 unique taxa. Overall model accuracy was 85% using 15 unique taxa when classifying almonds (76% accurate), avocados (88% accurate), walnuts (72% accurate), and whole grains (96% accurate). Additional statistical validation was conducted to confirm that the model was predictive of specific food intake and not the studies themselves. Conclusions Food consumption by healthy adults can be predicted using fecal bacteria as biomarkers. The fecal microbiota may provide useful fidelity measures to ascertain nutrition study compliance.

AbstractIntroductionThere is a long history of use for whole grain cereals as part of human dietary intakes with records of dietary grain consumption from the Middle Stone Ages. Whole grains are nutrient dense and research demonstrates that the healthiest diets (those associated with reduced risk of non-communicable diseases e.g. cardiovascular disease or cancer) are characterised by higher intake of fruit, vegetables, nuts and legumes and whole grains and lower intakes of red and processed meats. Currently, grains are a main energy and carbohydrate source and as such form a cornerstone of food based dietary guidelines and dietary guidance globally. However, grains also naturally contain contaminants and as a food category can represent a significant dietary source of foodborne contaminants.Materials and MethodsThe outcomes of a narrative review on the major contaminants present in whole grains, their potential health risks and suggested strategies to mitigate any risk are described. Contaminants are limited to mycotoxins (aflatoxinB1, ochratoxin A, Fumonisin B1, deoxynivalenol, zearalenone), heavy metals (e.g. arsenic, cadmium, lead) and the process contaminant acrylamide.ResultsWhole grains can contain more contaminants than refined versions e.g. whole grain rice with bran intact can have up to 80% more arsenic than white rice. However, whole grains also provide more nutrients which may mitigate against the impact of these contaminants. For example, for heavy metals, there is some evidence that dietary fibres (e.g. wheat bran) may bind to them and reduce their absorption, as can nutrients naturally found in whole grains e.g. zinc, magnesium or copper. Minerals such as iron, calcium, magnesium and zinc may also impede heavy metal absorption by down-regulating or competing for attachment to transporters that facilitate intestinal absorption. Although, strict regulatory thresholds and monitoring processes by competent authorities minimise any risk to public health, the consumer may further lessen any risk through their own dietary choices and food storage and preparation practicesDiscussionThere are a number of potential health-protective properties inherent to whole grains. Given that complete elimination of contaminants from grains is unlikely to be achieved, their presence merits continued monitoring with evidence to date suggesting any such risk does not outweigh the known benefits of wholegrain consumption.

Feeding grain whole to cattle generally results in a lower digestibility than that obtained with processed grain. If this problem could be overcome, feeding with whole grain would reduce processing costs, and the slower rate of starch digestion in the rumen could improve fibre digestion with potential beneficial effects on intake and animal production. Two strategies are available to increase the digestibility of whole grain. The first, longer term strategy relies on the selection or breeding of feed grains that are efficiently digested by cattle when fed whole. The review considers the chemical and physical properties of grains likely to increase the degree of grain damage during mastication, and increase the digestibility of the seed coat fraction. Research is required to determine the feasibility of selecting feed grains with these characteristics. The second strategy is to treat whole grain with chemicals or enzymes to increase digestibility of the seed coat and consequently whole grain digestion within the rumen. Considerable research has been conducted on the sodium hydroxide (NaOH) treatment of grain, and there is sufficient evidence from cattle experiments to indicate that digestibility, liveweight gain, and milk production on NaOH-treated whole grain can be similar to that on rolled grain, provided sufficient NaOH is applied. However, a number of practical and commercial considerations have limited the more widespread adoption of this technology on farms. Although ammonia treatment offers a more practical alternative to NaOH, digestibility and animal production responses have been highly variable, and research is required to identify effective ammoniation procedures. The increased availability of enzymes for livestock feeding has potentially provided another grain treatment option. The application of fibrolytic enzymes to whole grain prior to high-moisture storage or feeding, and their subsequent effect on grain digestibility, require research. The impact of grain characteristics, both physical and chemical, on the response to alkali or enzyme treatment also requires research.

Randomized Crossover Study

Consumption of whole-grain and sourdough breads is associated with improved glucose homeostasis. We examined the impact of commercial breads on biomarkers of glucose homeostasis in subjects at risk for glucose intolerance. In a randomized, crossover study, overweight or obese males ingested 11-grain, sprouted-grain, 12-grain, sourdough, or white bread on different occasions, matched for available carbohydrate (50 g) in part 1 (n=12) and bread mass (107 g) in part 2 (n=11), and blood glucose, insulin and glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) were determined for 3 h. In part 1, glucose response for sprouted-grain was lower than 11-grain, sourdough, and white breads. Insulin area under the curve (AUC) for sourdough and white was lower than 11-grain and sprouted-grain breads. GLP-1 response to sourdough was lower than all breads. In part 2, glucose and insulin AUC for sourdough was greater than 11-grain, sprouted-grain, and 12-grain breads. Sprouted-grain bread improved glycemia by lowering glucose response and increasing GLP-1 response. In overweight and obese men, the glycemic response to sprouted grain bread was reduced in both parts 1 and 2 while the other whole-grain test breads did not improve metabolic responses in the acute postprandial state.

The Impact

Background and context: Dietary whole grain (WG) intake helps prevent noncommunicable diseases (NCDs) such as cancers. However, 92.4% of the global adult population does not meet WG recommendations, and WG intake even decreased between 1990 and 2010. In Denmark, WG intake was similarly decreasing during the 1990s and 2000s, and the Whole Grain Partnership (WGP) was established in 2009 to counteract this development. Aim: To describe the development of this public-private partnership (PPP), the results achieved so far, lessons learned and implications for future initiatives. Strategy/Tactics: The strategy is twofold: increasing availability of WG and campaigning about the health benefits of WG. Program/Policy process: · Research and documentation of WG health benefits · Initiate partnership and functioning of organization and secretariat · Ensure clear WG definitions and dietary guidelines · Set targets and success criteria and monitor progress · Create incentives for industry to reformulate and develop new WG products and make it easy for consumers to identify WG product by developing and endorsing a WG logo · Gradually enriching all bread and flour with WG · Develop education materials for chefs, waiters, bakers, in-store personnel and health professionals · Yearly consumer campaigns. Outcomes: Mean WG intake has near doubled in less than 10 years (from 32 in 2009 to 61 g/day 2017). The increment in intake were also significant among the population groups eating the least WG. The number of WG products increased in this period from 150 to currently 800. Continuous monitoring of consumer behavior show a high knowledge, trust and use of the WG logo has increased during the period. What was learned: · To make the PPP work effectively it is crucial to work evidence based, set realistic targets, reinforce the reasons and advantages for partnering, measure and celebrate progress · The impact on population dietary habits is primarily due to the increased availability of WG product combined with a long-term campaigning activity promoting WG health benefits.

AbstractIncreased whole-grain (WG) consumption reduces the risk of CVD, type 2 diabetes and some cancers, is related to reduced body weight and weight gain and is related to improved intestinal health. Definitions of ‘WG’ and ‘WG food’ are proposed and used in some countries but are not consistent. Many countries promote WG consumption, but the emphasis given and the messages used vary. We surveyed dietary recommendations of fifty-three countries for mentions of WG to assess the extent, rationale and diversity in emphasis and wording of any recommendations. If present, recommendations were classified as either ‘primary’, where the recommendation was specific for WG, or ‘secondary’, where recommendations were made in order to achieve another (primary) target, most often dietary fibre intake. In total, 127 organisations were screened, including government, non-governmental organisations, charities and professional bodies, the WHO and European Food Safety Authority, of which forty-nine including WHO provide a WG intake recommendation. Recommendations ranged from ‘specific’ with specified target amounts (e.g. x g WG/d), ‘semi-quantitative’ where intake was linked to intake of cereal/carbohydrate foods with proportions of WG suggested (e.g. x servings of cereals of which y servings should be WG) to ‘non-specific’ based on ‘eating more’ WG or ‘choosing WG where possible’. This lack of a harmonised message may result in confusion for the consumer, lessen the impact of public health messages and pose barriers to trade in the food industry. A science-based consensus or expert opinion on WG recommendations is needed, with a global reach to guide public health decision making and increase WG consumption globally.
