- The concept for categorization of eating episodes in dietary surveys was originally developed in studies of shift workers to compare 'meal patterns' between night and day work shifts. The concept has been further improved through experience from applications in dietary surveys in other populations. In this paper, results from categorization of eating episodes in shift workers, elderly women and men during life transition periods, elderly female leg ulcer patients and obese men and their lean controls are shown and discussed. The categorization concept is based on seven food categories with food items of similar nutrient characteristics within each category. Each eating event is categorized as any of four types of 'meals' or four types of 'snacks' due to its combination of food categories. Thus, categorization is based on visible properties (food types) but at the same time reflecting invisible properties (nutrients). Criteria is also established to sub-categorize the 'meal' types as being either 'prepared' or 'quick-prepared' from a behavioural perspective. Use of a defined and reliable concept for categorization is necessary to study eating episodes in dietary surveys, their determinants and also consequences on health and performance. Nocturnal eating during the circadian nadir might affect nutritional status. Since increasingly western populations appear to be moving from regular and planned meals to more episodic eating 'around the clock', such analyses are of increasing interest in a bio-social perspective.

- Background: Because of changing food habits that may influence nutritional status it is important, especially in children, reproducibly to describe and analyse the timing and frequency of eating and the composition of different types of eating episodes. Objective: To describe eating patterns of 3-5-year-old Swedish preschool children by analysing 7 day food records using the Food-Based Classification of Eating Episodes (FBCE) model. Design: Food intakes were categorized into four types of "meals" and four types of "snacks", according to their food profile. Complete 7 day weighed and estimated food records for 109 children were processed and analysed. Results: On weekdays the children ate significantly more frequently than on weekend days, having 5.6 and 5.2 eating episodes per day, respectively. More eating episodes were classified as "meals" on weekdays than on weekend days: 72% and 60%, respectively. On average for the whole week, 43% of the daily energy intake was derived from "complete meals" (CM) and 34% from "incomplete meals" (IM). CM contributed significantly more energy and more nutrients, except for calcium, than did IM. In low-quality snacks (LS), sucrose contributed with about one-third of the energy content and the nutrient density was low. Conclusions: The qualitative FBCE model verified nutritional characteristics of the children's diet previously found in the same cohort by the traditional dietary assessment methods. Processing of the dietary data by the model to show the prevalence and temporal distribution of eating episodes appears to be an applicable tool for nutritional screening of children's eating patterns

- The aim of this study was to examine possible causes of malnutrition in geriatric patients on admission to hospital by evaluation and comparison of their meal pattern between periods of working, retirement and hospitalization, respectively. Forty-five consecutive patients aged 60 years or older participated. By use of modified dietary history interviews, a retrospective assessment of food intake was carried out. A qualitative system for meal classification was then applied. In the retirement period there was a strong reduction in daily eating frequency when compared to working and hospital periods. Thus, the daily intake and also distribution of energy and nutrients seem to be reduced during retirement, which might lead to nutritional deficiency.

- The food selection and nutrient intake were investigated in women with anorexia nervosa, bulimia nervosa and controls. Methods Dietary data was obtained by 24-hour recall, and 7-day recording among eating disordered patients, and by 3-day registration among controls. Results: The intake of energy and nutrients differed from controls, as expected, while there were no differences between anorectics and bulimics in this respect, except for iron. There were only minor differences among the three groups studied with respect to nutrient density. Energy percentages of protein, fat, and carbohydrates, were similar in all groups, but a subdivision of the macronutrients into respective sources showed that bulimics had a lower relative and absolute intake of carbohydrates from bread and cereals than anorectics and controls. Conclusion: Eating disorder patients, despite their marginal food intake, still met the minimum requirement for most nutrients according to the Nordic Nutrient recommendations. Abbreviations: AN = anorexia nervosa, AN/BN = anorectic bulimics, BMI = body mass index, BN = bulimia nervosa, DSM-III-R = Diagnostic and Statistical Manual of Mental Disorders, ED = eating disorder, NNR = Nordic Nutrient Recommendation

- Nutritional assessment is the interpretation of information obtained from dietary, biochemical, anthropometric and clinical studies. In individuals, qualitative or quantitative food consumption data may be collected by food frequency questionnaires or interviews (retrospective methods), by use of food records (prospective methods); weighed food record, estimated food record or menu record, or by observations. Nutrient values derived from food composition data or direct chemical analysis represent the maximum available to the body and not the amount actually absorbed and utilized. The design of the study is crucial and the methods for carrying it out are aimed at minimizing bias to improve internal and external validity. This paper will focus on factors of importance to improve the internal validity of dietary assessment studies; selection of method; data collection, assessment of nutrient intakes from food consumption data and evaluation of data.

- The aim of the study was to describe the nutritional intake, meal patterns, physical activity and need for help in nine women living in their own homes and being treated for venous leg ulcers. Food habits were identified by use of interviews and food diaries completed by the women during a period of seven days. The intake of energy and nutrients from 304 eating events during seven days was calculated and meal patterns were evaluated using a qualitative system for meal classification. Physical activity and the degree of need were identified with the help of interviews. The intakes of energy and key nutrients for wound healing, such as protein, vitamin C and zinc, were not optimal according to the Swedish nutrition recommendations, although food habits were well organized. Most of the women had hardly any physical activities and the need of help and support varied, from daily visits to visits every second week.

- Little is known about the precise mechanism that relates skeletal muscle glycogen to muscle fatigue. The aim of the present study was to examine the effect of glycogen on sarcoplasmic reticulum (SR) function in the arm and leg muscles of elite cross-country skiers (n = 10, (V) over dot(O2 max) 72 +/- 2 ml kg(-1) min(-1)) before, immediately after, and 4 h and 22 h after a fatiguing 1 h ski race. During the first 4 h recovery, skiers received either water or carbohydrate (CHO) and thereafter all received CHO-enriched food. Immediately after the race, arm glycogen was reduced to 31 +/- 4% and SR Ca2+ release rate decreased to 85 +/- 2% of initial levels. Glycogen noticeably recovered after 4 h recovery with CHO (59 +/- 5% initial) and the SR Ca2+ release rate returned to pre-exercise levels. However, in the absence of CHO during the first 4 h recovery, glycogen and the SR Ca2+ release rate remained unchanged (29 +/- 2% and 77 +/- 8%, respectively), with both parameters becoming normal after the remaining 18 h recovery with CHO. Leg muscle glycogen decreased to a lesser extent (71 +/- 10% initial), with no effects on the SR Ca2+ release rate. Interestingly, transmission electron microscopy (TEM) analysis revealed that the specific pool of intramyofibrillar glycogen, representing 10-15% of total glycogen, was highly significantly correlated with the SR Ca2+ release rate. These observations strongly indicate that low glycogen and especially intramyofibrillar glycogen, as suggested by TEM, modulate the SR Ca2+ release rate in highly trained subjects. Thus, low glycogen during exercise may contribute to fatigue by causing a decreased SR Ca2+ release rate.

Tidskriftsartikel (refereegranskat)abstract
- As the use of food supplements increases, voices are being raised questioning the safety of these products. As a contribution to understanding the trace and major elemental composition of food supplements and their potential health risks, this study presents concentrations of 71 elements in 138 supplements, categorised into synthetic products and three groups of products with natural ingredients. Concentrations were converted into average daily doses (ADDs) and compared to tolerable daily intakes (TDIs). For elements where we found significant ADDs relative to the TDI a comparison was also made to the normal dietary intake. Our main findings are that: 1) Most elements display highly variable concentrations in food supplements; more so than in normal foodstuff; 2) For ten of the analysed elements some products rendered ADDs > 50% of the TDI. Half of the elements were essential (Fe, Mn, Se, Mo, Zn), and as such motivated in food supplements. The other half (As, Pb, Cd, Al, Ni) represent non-essential and highly toxic elements, where the occurrence in food supplements ought to be viewed as contamination. Although none of these toxic metals were declared on any product’s table of content, several products gave high ADDs - in several cases even exceeding the TDIs; 3) The risk of reaching high ADDs for the toxic elements is strongly associated with products that contain marine ingredients (e.g. algae, mussels etc), and to some degree products of terrestrial plant-based origin. The health of consumers would benefit if food regulatory frameworks were updated to better address the risks of food supplements occasionally being contaminated with different toxic metals, for example by setting maximum permissible concentrations for a longer list of elements.

- BackgroundGrowing evidence points to a link between specific fatty acids ingested through the diet and human health. Chain length, saturation degree, and position of double bonds in fatty acids determine their effect in humans. Omega-3 and omega-6 fatty acids have been recognized for their contribution to the prevention and/or treatment of diabetes, cancer, visual impairment, cardiovascular diseases, as well as neurological and musculoskeletal disorders.Scope and approachHumans cannot synthesize these fatty acids in sufficient amounts and need to absorb them through the diet. Oleaginous microalgae constitute a promising, sustainable source of such fatty acids, as they can accumulate up to 85% of lipids on a cell dry weight basis.Key findings and conclusionsThe present review summarizes the potential of oleaginous microalgae as a convenient, economical, and sustainable source of polyunsaturated fatty acids, and explores their beneficial role in human health. The growing prevalence of cardiovascular diseases and changing dietary preferences are driving the increasing demand for microbial omega-3 fatty acids. Following the COVID-19 pandemic, the importance of a healthy immune system has further strengthened the market for omega-3 fatty acids.
