The DONALD study (Dortmund Nutritional and Anthropometric Longitudinally Designed study) gives the opportunity to evaluate long-term food and nutrient intake data on the basis of 3 d weighed dietary records of infants, children and adolescents since 1985. In this paper, we examine changes in energy and macronutrient intakes (protein, fat, saturated, mono- and polyunsaturated fatty acids, carbohydrates and added sugars) of 795 2–18-year-old subjects between 1985 and 2000 (4483 records). No significant changes in intakes of energy and of protein, polyunsaturated fatty acids and added sugars (as % energy intake, E %) were found. Fat intake decreased significantly in all age groups (between -0·20 and -0·26 E %/year), as well as intake of saturated fatty acids (between -0·11 and -0·14 E %/year) and monounsaturated fatty acids (between -0·07 and -0·014 E %/year). This decline was compensated for by a significant increase in carbohydrate intake (between +0·18 and +0·27 E %/year). The changes in macronutrient intake were mainly due to a decreased consumption of fats–oils (between -0·29 and -1·26 g/year) and meat–fish–eggs (between -0·21 and -2·92 g/year), whereas consumption of bread–cereals (between +0·12 and +2·42 g/year) and potatoes–pasta–rice (between +0·15 and +2·26 g/year) increased slightly. However, since recommended fat intake and fatty acid composition was not reached at the end of the study period by far, further efforts will be necessary to improve macronutrient composition and to stabilize favourable dietary habits.

AbstractThe strain SARS-CoV-2, newly emerged in late 2019, has been identified as the cause of COVID-19 and the pandemic declared by WHO in early 2020. Although lipids have been shown to possess antiviral efficacy, little is currently known about lipid compounds with anti-SARS-CoV-2 binding and entry properties. To address this issue, we screened, overall, 17 polyunsaturated fatty acids, monounsaturated fatty acids and saturated fatty acids, as wells as lipid-soluble vitamins. In performing target-based ligand screening utilizing the RBD-SARS-CoV-2 sequence, we observed that polyunsaturated fatty acids most effectively interfere with binding to hACE2, the receptor for SARS-CoV-2. Using a spike protein pseudo-virus, we also found that linolenic acid and eicosapentaenoic acid significantly block the entry of SARS-CoV-2. In addition, eicosapentaenoic acid showed higher efficacy than linolenic acid in reducing activity of TMPRSS2 and cathepsin L proteases, but neither of the fatty acids affected their expression at the protein level. Also, neither reduction of hACE2 activity nor binding to the hACE2 receptor upon treatment with these two fatty acids was observed. Although further in vivo experiments are warranted to validate the current findings, our study provides a new insight into the role of lipids as antiviral compounds against the SARS-CoV-2 strain.

The aim of this study was to determine the effect of the addition of spices (garlic, rosemary, thyme, sage or clove) on the chemical and sensory characteristics of burgers elaborated with lamb meat from different locations (L: only leg; LNB 2/3 leg + 1/3 neck and breast). Formulation type (L vs. LNB) modified the chemical composition. L burgers showed lower values of fat, saturated fatty acids, monounsaturated fatty acids and higher moisture and polyunsaturated fatty acids content than LNB samples, with both types of burgers maintaining the nutritional indexes (P/S and n6/n3) within the recommended amounts. Nevertheless, the type of formula did not influence the sensory properties of lamb burgers. By contrast, the spice addition affected these characteristics over the period of time considered in this study. At the end of storage their global quality could be listed in the following order, from major to minor rate: Sage > Rosemary > Garlic > Thyme > Clove burgers.

The transformations of cheese components during ripening, especially the evolution of free fatty acids were studied using the gas-chromatographic method. The proteolitic and lypolitic enzymes were added in semi-hard cheese assortment for cheese quality improvment. Three types of semi-hard cheese were taken into study: blank (M), cheese with lypolitic enzymes (Bl) and cheese with proteolytic enzymes (Bp). Samples from these cheeses were collected at three different moment of times: at obtaining, at 25 day of ripening and at 50 day of ripening. The content of saturated fatty acids (SFA), monounsaturated fatty acids (MUFA) and polyunsaturated fatty acids (PUFA) was determined for each sample.

Fat Intake

Obesity is defi ned as excessive fat accumulation fat that causes excess weight. Diseases that related with obesity are diabetes, dyslipidemia, hypertension and other degenerative diseases. Factors that affect obesity are dietary factors,history of hereditary, lifestyle, psychological factors, environment, individual, and biological which may infl uence energy intake and expenditure. Consumption of high fat in a long period without any activity for energy expenditure can increase the risk of obesity. This study was aimed to analyse the correlation between fat intake and physical activity with obesity among adolescent girls in SMP Bina Insani junior high school Surabaya. This study employed a case control study design with a retrospective approach. The research participants were 32 female students in Bina Insani junior high school Surabaya (16 control and 16 case samples). Total fat intake was relatively low. The intake of Monounsaturated Fatty Acids (MUFA) and Polyunsaturated Fatty Acids (PUFA) were low while Saturated Fatty Acids (SFA) were high. There was no correlation between fat intake and obesity (ρ=0.240), but there was a signifi cant correlation between physical activity ρ=0.006 (OR= 9.533, 95% CI: 1.847-49.204) with adolescent obesity. The very mild physical activity give a risk as much as 9.533 times greater for developing obesity than the mild physical.Therefore, it is necessary to increase physical activity among adolescent girls by doing sports to reduce the risk of obesity.

Age-related alterations of fatty acid composition in liver and brain of AKR mice was investigated. The effect of savory essential oil (Satureja hortensis L.), added with drinking water on fatty acid composition in these organs and the processes of lipid peroxidation in erythrocytes were estimated. It was found that during aging the percentage of saturated fatty acids and polyunsaturated fatty acids decreased while monounsaturated fatty acids increased. The development of leukemia was accompanied by the increase of saturated and polyunsaturated fatty acids percentage and a decrease of monounsaturated fatty acids amount. In the liver aging caused the increase in the percentage of saturated fatty acids, the decrease of monounsaturated fatty acids, while the amount of polyunsaturated fatty acids was not changed. Leukemia (after 8 month) was accompanied by the increase of percentage of monounsaturated fatty acids and the decrease in the amount of oleinic and docosohexaenic acids. The intake of savory essential oil was accompanied by intensification of polyunsaturated fatty acids synthesis in mice liver and reduction of lipid peroxidation products content.

Weight Changes

A moderately high-fat Mediterranean diet does not promote weight gain. This study aimed to investigate the association between dietary intake of specific types of fat and obesity and body weight. A prospective cohort study was performed using data of 6942 participants in the PREDIMED trial, with yearly repeated validated food-frequency questionnaires, and anthropometric outcomes (median follow-up: 4.8 years). The effects of replacing dietary fat subtypes for one another, proteins or carbohydrates were estimated using generalized estimating equations substitution models. Replacement of 5% energy from saturated fatty acids (SFA) with monounsaturated fatty acids (MUFA) or polyunsaturated fatty acids (PUFA) resulted in weight changes of −0.38 kg (95% Confidece Iinterval (CI): −0.69, −0.07), and −0.51 kg (95% CI: −0.81, −0.20), respectively. Replacing proteins with MUFA or PUFA decreased the odds of becoming obese. Estimates for the daily substitution of one portion of red meat with white meat, oily fish or white fish showed weight changes up to −0.87 kg. Increasing the intake of unsaturated fatty acids at the expense of SFA, proteins, and carbohydrates showed beneficial effects on body weight and obesity. It may therefore be desirable to encourage high-quality fat diets like the Mediterranean diet instead of restricting total fat intake.

The effects of adding flaxseed or fish oil to the diet of dairy cows on the chemical and physical profile of Mozzarella cheese production were studied. The experiment involved 24 Friesian cows, divided into 3 groups accordingly fat supplementation: basal diet (CT), diet supplemented with flaxseed (FS) or fish oil (FO). Mozzarella cheeses were manufactured from bulk milk of each group. Bulk milk was analysed for chemical composition and renneting parameters. Mozzarella cheeses were analysed for chemical composition, fatty acid profile, and textural properties. Results suggest that Mozzarella cheese from cows receiving flaxseed supplementation showed a decrease in saturated fatty acids (SFA), an increase in monounsaturated fatty acids (MUFA), and in polyunsaturated fatty acids (PUFA) compared with control Mozzarella cheese. The increased dietary intake of C18:3 in flaxseed supplemented cows resulted in increased levels of trans-11 C18:1, and of CLA cis-9 trans-11 C18:2, and in low Atherogenic and Trombogenic Indexes. FO Mozzarella cheese showed compositional and textural properties quite similar to CT Mozzarella cheese; however, increased levels of n-3 polyunsaturated fatty acids in FO Mozzarella were found.

While high levels of saturated fatty acids are associated with impairment of cardiovascular functions, n-3 polyunsaturated fatty acids (PUFAs) have been shown to exert protective effects. However the molecular mechanisms underlying this evidence are not completely understood. In the present study we have used rat H9c2 ventricular cardiomyoblasts as a cellular model of lipotoxicity to highlight the effects of palmitate, a saturated fatty acid, on genetic and epigenetic modulation of fatty acid metabolism and fate, and the ability of PUFAs, eicosapentaenoic acid, and docosahexaenoic acid, to contrast the actions that may contribute to cardiac dysfunction and remodeling. Treatment with a high dose of palmitate provoked mitochondrial depolarization, apoptosis, and hypertrophy of cardiomyoblasts. Palmitate also enhanced the mRNA levels of sterol regulatory element-binding proteins (SREBPs), a family of master transcription factors for lipogenesis, and it favored the expression of genes encoding key enzymes that metabolically activate palmitate and commit it to biosynthetic pathways. Moreover, miR-33a, a highly conserved microRNA embedded in an intronic sequence of the SREBP2 gene, was co-expressed with the SREBP2 messenger, while its target carnitine palmitoyltransferase-1b was down-regulated. Manipulation of the levels of miR-33a and SREBPs allowed us to understand their involvement in cell death and hypertrophy. The simultaneous addition of PUFAs prevented the effects of palmitate and protected H9c2 cells. These results may have implications for the control of cardiac metabolism and dysfunction, particularly in relation to dietary habits and the quality of fatty acid intake.

The UK Food Standards Agency convened a group of expert scientists to review current research investigating the optimal dietary intake forn-9cis-monounsaturated fatty acids (MUFA). The aim was to review the mechanisms underlying the reported beneficial effects of MUFA on CHD risk, and to establish priorities for future research. The issue of optimal MUFA intake is contingent upon optimal total fat intake; however, there is no consensus of opinion on what the optimal total fat intake should be. Thus, it was recommended that a large multi-centre study should look at the effects on CHD risk of MUFA replacement of saturated fatty acids in relation to varying total fat intakes; this study should be of sufficient size to take account of genetic variation, sex, physical activity and stage of life factors, as well as being of sufficient duration to account for adaptation to diets. Recommendations for studies investigating the mechanistic effects of MUFA were also made. Methods of manipulating the food chain to increase MUFA at the expense of saturated fatty acids were also discussed.
