Decoding diets: insights on ultra-processed food consumption among Lebanese adults from the updated LEBANese natiONal food consumption survey (LEBANON-FCS).
Ultra-processed foods are evident to play a role in the development of nutrition-related non-communicable diseases (NR-NCDs). There's a scarcity of data in the Eastern Mediterranean Region (EMR) regarding ultra-processed food consumption, which highlights the need for such data in this region that is witnessing a nutrition transition. This study was conducted to assess the dietary pattern of Lebanese adults according to different degrees of food processing.
A cross-sectional study involving a nationally representative sample (n = 444) of Lebanese adults (18-64 years) was conducted over the course of 5 months. A validated food frequency questionnaire and two non-consecutive 24-h recalls were used to collect the dietary intake. Sociodemographic and medical characteristics were collected using a validated questionnaire. Anthropometric measurements were taken by trained dietitians. Food items were classified according to the NOVA food classification system, and the percent contribution of every type of processing to the energy intake was calculated.
Ultra-processed foods contributed to the highest percent of energy intake in the sample (46.7%), followed by unprocessed and minimally processed foods (39.6%). Being male, and younger increased the odds of higher ultra-processed food intake; being employed and food secure increased the odds of a higher NOVA-UPF score. Compared with participants in Beirut, participants residing in North Lebanon and Akkar had higher odds of having a high UPF intake and lower odds of having a high NOVA-UPF score. The three most contributing food items to energy intake were ultra-processed (breads and breakfast cereals, fast foods, sweets and desserts). Compared to the unprocessed and minimally processed food diet fraction, the ultra-processed food diet fraction was significantly higher in sodium and thiamin and lower in proteins, fiber, and essential vitamins and minerals such as vitamins A, D, B12, folate, iron, calcium, and magnesium.
UPF intake was the main contributor to TEI, and the intake was considerably higher among those who reported having renal disease, younger adults, and males. In comparison to the minimally processed diet fraction, the UPF diet fraction was found to have considerably greater levels of sodium and thiamin and lower levels of proteins, fiber, and essential vitamins and minerals. The study findings call for public health policies and interventions to encourage the consumption of minimally processed foods and decrease the consumption of ultra-processed foods, especially sweets and sweetened beverages, which are especially problematic.

Characterization of the degree of food processing in the European Prospective Investigation into Cancer and Nutrition: Application of the Nova classification and validation using selected biomarkers of food processing.
Epidemiological studies have demonstrated an association between the degree of food processing in our diet and the risk of various chronic diseases. Much of this evidence is based on the international Nova classification system, which classifies food into four groups based on the type of processing: (1) Unprocessed and minimally processed foods, (2) Processed culinary ingredients, (3) Processed foods, and (4) "Ultra-processed" foods (UPF). The ability of the Nova classification to accurately characterise the degree of food processing across consumption patterns in various European populations has not been investigated so far. Therefore, we applied the Nova coding to data from the European Prospective Investigation into Cancer and Nutrition (EPIC) in order to characterize the degree of food processing in our diet across European populations with diverse cultural and socio-economic backgrounds and to validate this Nova classification through comparison with objective biomarker measurements.
After grouping foods in the EPIC dataset according to the Nova classification, a total of 476,768 participants in the EPIC cohort (71.5% women; mean age 51 [standard deviation (SD) 9.93]; median age 52 [percentile (p)25-p75: 58-66] years) were included in the cross-sectional analysis that characterised consumption patterns based on the Nova classification. The consumption of food products classified as different Nova categories were compared to relevant circulating biomarkers denoting food processing, measured in various subsamples (N between 417 and 9,460) within the EPIC cohort via (partial) correlation analyses (unadjusted and adjusted by sex, age, BMI and country). These biomarkers included an industrial transfatty acid (ITFA) isomer (elaidic acid; exogenous fatty acid generated during oil hydrogenation and heating) and urinary 4-methyl syringol sulfate (an indicator for the consumption of smoked food and a component of liquid smoke used in UPF).
Contributions of UPF intake to the overall diet in % grams/day varied across countries from 7% (France) to 23% (Norway) and their contributions to overall % energy intake from 16% (Spain and Italy) to >45% (in the UK and Norway). Differences were also found between sociodemographic groups; participants in the highest fourth of UPF consumption tended to be younger, taller, less educated, current smokers, more physically active, have a higher reported intake of energy and lower reported intake of alcohol. The UPF pattern as defined based on the Nova classification (group 4;% kcal/day) was positively associated with blood levels of industrial elaidic acid (r = 0.54) and 4-methyl syringol sulfate (r = 0.43). Associations for the other 3 Nova groups with these food processing biomarkers were either inverse or non-significant (e.g., for unprocessed and minimally processed foods these correlations were -0.07 and -0.37 for elaidic acid and 4-methyl syringol sulfate, respectively).
These results, based on a large pan-European cohort, demonstrate sociodemographic and geographical differences in the consumption of UPF. Furthermore, these results suggest that the Nova classification can accurately capture consumption of UPF, reflected by stronger correlations with circulating levels of industrial elaidic acid and a syringol metabolite compared to diets high in minimally processed foods.

Consumption of ultra-processed foods is associated with dietary iron availability, anemia, and excess weight in socially vulnerable children.
Eating habits during childhood have undergone significant changes, with a notable increase in the consumption of ultra-processed foods (UPF). This situation deserves attention, given the close relationship between UPF and adverse health outcomes. This is due to the nutritional composition of UPF, which has high levels of health-critical nutrients such as sugar, fat, and sodium, thus compromising the overall quality of the diet. An excess of these nutrients can increase the risk of developing excess weight, nutritional deficiencies, and chronic diseases during childhood. Among the nutritional deficiencies is iron. This is due to the fact that UPF are not good sources of iron. This, combined with the fact that UPF is low in nutrients that help make iron more available, such as vitamin C, increases the risk of developing anemia. Therefore, this study aimed to assess the availability of iron, as well as the presence of anemia and excess weight in children living in situations of social vulnerability, and to determine their association with the consumption of UPF.
This is a population-based cross-sectional study. Children aged between 6 and 59 months living in slums were included. The presence of excess weight was assessed by measuring weight and height, and the presence of anemia was determined by hemoglobin concentration, assessed using the HemoCue portable hemoglobinometer. A 24-h food recall was also used to assess the relative calorie intake of UFP and the dietary availability of iron using an algorithm. All statistical analyses were carried out using the statistical software Jamovi.
In this study, 443 children were included; 19.2 % were classified as with excess weight, and 55.6 % were anemic; the average absorbable iron content was 0.54 (SD ± 0.42) mg, and 39.2 % of the calories consumed came from UPF. The association analysis showed that children with calorie share relative to UPF had a decrease of -0.12 mg of bioavailable iron (β: -0.12; 95 % CI: -0.23; -0.01). It was also possible to identify that the higher calorie share of UPF increased their chances of being classified as with excess weight and anemic by up to 116 % (OR: 2.16; 95 % CI 1.05; 4.46) and 145 % (OR: 2.45; 95 % CI: 1.26; 4.78), respectively.
The relationship found between UPF consumption and the availability of iron in the diet, excess weight, and anemia calls for attention, especially in contexts of social vulnerability. These findings demonstrate the need for greater attention to nutrition in childhood to promote an adequate and healthy diet. This can help to change the nutritional and epidemiological panorama of the population, contributing to a better general state of health for future generations of adults.

Plant-based dietary patterns and ultra-processed food consumption: a cross-sectional analysis of the UK Biobank.
Dietary shift towards more plant-based options is increasingly popular, but the quantity of ultra-processed foods (UPFs) they contain is largely unknown. This study assessed the level of UPF and minimally processed food consumption among regular and low red meat eaters, flexitarians, pescatarians, vegetarians and vegans in a large dataset of United Kingdom (UK) adults.
This is a cross-sectional analysis of the UK Biobank participants recruited between December 19, 2006, and October 1, 2010. Responses to food frequency questions were used to identify diet types for vegans (never eating any animal-based foods); vegetarians (never eating meat/fish); pescatarians (never eating meat); flexitarians (consumed fish/meat under twice a week); low red meat eaters (consumed fish/poultry more than once a week but red/processed meat under twice a week); and regular red meat eaters (consumed red/processed meat more than once a week). Consumption of all food and drinks collected in 24-h recalls between April 29, 2009, and June 28, 2012, were categorised using the Nova classification. The primary outcomes are the consumption of UPFs and minimally processed foods, expressed as a percentage of daily food intake (grams/day). Multivariable linear regression assessed the mean percentage point difference in UPF and minimally processed food consumption between diet types.
This study included 199,502 UK Biobank participants (mean age 58.2 [standard deviation 7.9] years; 55.1% women). The mean UPF consumption was 24.2%, 21.9%, 22.0%, 20.4%, 23.8%, and 22.7% among 75,091 regular red meat eaters, 70,144 low red meat eaters, 45,057 flexitarians, 4932 pescatarians, 4119 vegetarians and 159 vegans, respectively. The adjusted results suggested that compared with regular red meat eaters, UPF consumption was 1.3 percentage points higher among vegetarians (95% confidence interval [CI]: 0.9, 1.7) and lower among low red meat eaters (-1.3, 95% CI: -1.4, -1.1), flexitarians (-0.8, 95% CI: -1.0, -0.7), and pescatarians (-1.6, 95% CI: -1.9, -1.2). The UPF consumption in vegans were not significantly different from regular red meat eaters (1.2 percentage points, 95% CI: -0.7, 3.2). Minimally processed food consumption was higher in all other types of diet than regular red meat eaters, with an adjusted percentage point difference ranged from 0.4 (95% CI: 0.005, 0.9) for vegetarians to 3.2 (95% CI: 1.0, 5.5) for vegans compared with regular red meat eaters.
This UK-based study found higher UPF consumption in vegetarian diets and lower in diets with a modest amount of meat or fish. It is important that policies which encourage the urgently needed transition to more sustainable dietary patterns also promote rebalancing diets towards minimally processed foods.
