Background: The gut microbiome as well as dietary habits have recently been established as environmental contributors to the pathogenesis of multiple sclerosis (MS), a T-cell-mediated autoimmune disease of the central nervous system (CNS). Objective: To summarize recent findings on the Janus-faced effects of dietary short-chain fatty acids (SCFAs) and long-chain fatty acids (LCFAs) on T-cell immunity with a special focus on the gut and the microbiome as an interface linking diet and T-cell responses during MS. Methods: Review article. Results: The autoimmune basis of MS most likely stems from an imbalance between pro-inflammatory T helper cell (Th)1 and Th17 cells and anti-inflammatory or regulatory mechanisms including regulatory T cells (Treg). Hence, the rationale of currently available therapeutic interventions is to either suppress pathogenic Th1/Th17 and/or to foster Treg responses. Dietary fatty acids are often discussed for their detrimental role in MS. However, recent studies investigating saturated fatty acids in animal models of MS revealed harmful as well as beneficial effects depending on their aliphatic chain length. Conclusion: Dietary SCFAs constitute interesting candidates as safe and potent add-on therapy in the immunomodulatory treatment armamentarium for relapsing-remitting MS.

Recent evidence has highlighted that fat accumulation, particularly abdominal fat distribution, is strongly associated with metabolic disturbance. It is also well-recognized that the metabolic responses to variations in macronutrients intake can affect body composition. Previous studies suggest that the quality of dietary fats can be considered as the main determinant of body-fat deposition, fat distribution, and body composition without altering the total body weight; however, the effects of dietary fats on body composition have controversial results. There is substantial evidence to suggest that saturated fatty acids are more obesogen than unsaturated fatty acids, and with the exception of some isomers like conjugate linoleic acid, most dietary trans fatty acids are adiposity enhancers, but there is no consensus on it yet. On the other hand, there is little evidence to indicate that higher intake of the n-3 and the n-6 polyunsaturated fatty acids can be beneficial in attenuating adiposity, and the effect of monounsaturated fatty acids on body composition is contradictory. Accordingly, the content of this review summarizes the current body of knowledge on the potential effects of the different types of dietary fatty acids on body composition and adiposity. It also refers to the putative mechanisms underlying this association and reflects on the controversy of this topic.

Improving dietary habits at a young age could prevent adverse health outcomes. The aim was to gain insight into the adequacy of the dietary intake of Dutch toddlers, which may provide valuable information for preventive measures. Data obtained from the Dutch National Food Consumption Survey 2012–2016 were used, which included 672 children aged one to three years. Habitual intakes of nutrients were evaluated according to recommendations set by the Dutch Health Council. Specific food groups were evaluated according to the Dutch food-based dietary guidelines. For most nutrients, intakes were estimated to be adequate. High intakes were found for saturated fatty acids, retinol, iodine, copper, zinc, and sodium. No statement could be provided on the adequacy of intakes of alpha-linoleic acids, N-3 fish fatty acids, fiber, and iron. 74% of the toddlers used dietary supplements, and 59% used vitamin D supplements specifically. Total median intakes of vegetables, bread, and milk products were sufficient. Consumption of bread, potatoes and cereals, milk products, fats, and drinks consisted largely of unhealthy products. Consumption of unfavorable products may have been the cause of the observed high and low intakes of several nutrients. Shifting towards a healthier diet that is more in line with the guidelines may positively affect the dietary intake of Dutch toddlers and prevent negative health impacts, also later in life.

The objective of the present study was to describe the intake of dietary fatty acids among healthy 15-year-old boys and girls and to relate the intake of specific fatty acids and the fatty acid composition of the serum cholesterol esters to serum lipid, apolipoprotein (Apo) and insulin concentrations respectively. Fifty-two girls and forty-two boys were randomly selected from the official population register. Unexpectedly, significant inverse associations were found between the dietary content of saturated fatty acids with a chain length of four to fifteen C atoms, mainly derived from milk fat, as well as the corresponding fatty acids in the serum cholesterol esters, on the one hand and the serum concentrations of cholesterol and ApoB on the other. The estimated dietary intake of 4:0–10:0, 12:0 and 14:0 respectively, were all significantly inversely related to the serum cholesterol (r-0.32,r-0.31,r-0.30, all P<0.05) and ApoB (r-0.42,r-0.42, andr-0.40, all P<0.05) concentrations in girls and 12:0 to the ApoB concentration (r-0.55, P<0.01) in boys. The proportions of 12:0 and 15:0 in the serum cholesterol esters were negatively correlated with the serum cholesterol concentrations in both girls (r-0.34,r-0.32, P<0.05) and boys (r-0.53, P<0.01;r-0.32, P<0.05) and with the ApoB concentrations among boys (r-0.61, P<0.01;r-0.43, P<0.05). It is conceivable that milk fat contains or is associated with some component in the diet, or some other characteristics of the food intake, which counterbalances the expected positive relationships between saturated fat intake and lipid levels.

Eight Holstein cows with body weight 570 ± 43 kg and 60 ± 20 lactation days were distributed in a double Latin square design with four 21-day periods to determine the effects of feeding ground or whole flaxseed with or without monensin supplementation (0.02% on a dry matter basis) on fatty acid profile of butter stored for 15 and 45 days. Ground flaxseed supply, in comparison to whole flaxseed, reduced relative percentages of 16:0, cis7-16:1, 17:0, and cis10-17:1 but it increased those of cis9,trans11-18:2, cis3-18:3, and omega 3 fatty acids in butter fat, reducing relative percentage of medium-chain fatty acids and increasing the content of polyunsaturated fatty acids. Supplementation with monensin increased relative percentages of cis9,trans11-18:2 and tended to increase relative percentage of 17:0 and decrease that of saturated fatty acids in butter. Butter from cows fed diet with monensin presented lower relative percentages of cis 6-20:4. Relative percentages of cis 9-16:1, cis10-17:1, 18:0, trans11-18:1, cis9-18:1, cis3-18:3, cis6-20:4 in butter stored for 15 days were higher than those stored for 45 days and the relative percentages of cis3-20:5 tended to decrease with the increase of storage period. As a result, relative percentages of saturated fatty acids and medium-chain fatty acids increased with storage time, while those of monounsaturated and long-chain fatty acids decreased. Butter enriched with polyunsaturated fatty acids may have a shorter shelf life due to the negative effect of storage on fatty acid profile which may cause oxidation and rancidity.

The aging population is a significant social, medical and economic problem due to increasing prevalence of chronic diseases in elderly population. Alzheimer's disease (AD) is the most common form of dementia and the most common neurodegenerative disease. It is characterized by a progressive deterioration of memory and cognitive function. So far, there is neither an effective prevention nor cure for dementia, so more and more attention is paid to the prevention of this group of diseases, particularly to the appropriate diet. Preventive intervention gives the best results if introduced before the first symptoms of dementia, i.e., around the age of 50. This is when the nutritional status, number of synapses, cognition, and neuropathological changes in the nervous system compensate each other, which increases the chances of staying healthy for a longer period of time. It has been proven that dietary habits, which lead to the development of cardiovascular and metabolic diseases, significantly increase the risk of dementia. On the other hand, a Mediterranean diet rich in antioxidants, fiber and omega-3 polyunsaturated fatty acids may have a protective effect on the neurodegenerative process. The beneficial effect of many nutrients on the course of AD has been demonstrated. These include: glutathione, polyphenols, curcumin, coenzyme Q10, vitamins B6, B12, folic acid, unsaturated fatty acids, lecithin, UA, caffeine and some probiotic bacteria. A diet rich in saturated fatty acids and branched-chain amino acids (BCAA) promotes the progression of dementia. Dietary intervention should be introduced as early as possible to minimize the risk of developing dementia. The Mediterranean and DASH diets have been documented to protect against AD. However, the MIND diet is reported to be much more effective in preventing cognitive decline/dementia than either the Mediterranean or DASH diets alone.

Introduction: The associations of dietary total fatty acids and the classes saturated, monounsaturated, and polyunsaturated fatty acids (SFAs, MUFAs, and PUFAs) with coronary heart disease (CHD) remain contentious. Moreover, the role of isocaloric macronutrient substitutions and specific food sources of SFAs, particularly in European context, is unclear. Hypothesis: We evaluated the hypothesis that associations of dietary fatty acids vary depending on specific macronutrient substitutions and food sources of SFAs. Methods: We conducted case-cohort analyses including 10,529 incident CHD cases and a random subcohort of 16,730 men and women selected from 385,747 eligible participants in nine countries of the European Prospective Investigation into Cancer and Nutrition Study. Habitual diet was assessed using country-specific dietary questionnaires, and macronutrient intakes were estimated using standardised nutrient databases. Country-specific HRs (95% CIs) per 5% energy intake from dietary total fatty acids, SFAs, MUFAs, and PUFAs were estimated using Prentice-weighted Cox regression models and pooled using random-effects meta-analyses, with and without considering isocaloric macronutrient substitutions. The associations of dietary SFAs from different food sources, including specific macronutrient substitutions, with CHD were also investigated. Results: There was no evidence of associations of dietary total fatty acids, SFAs, MUFAs, or PUFAs with incident CHD, regardless of the substitution macronutrient. Each 1% higher energy intake of SFAs from yoghurt, cheese, and fish were associated with a 7% (95% CI 1-12%), 2% (0-4%) and 13% (0-25%) lower CHD incidence, while SFAs from red meat and butter were associated with a 7% (2-12%) and 2% (0-4%) higher CHD incidence, respectively. Conclusions: There was no evidence of associations of dietary total fatty acids, SFAs, MUFAs, and PUFAs, with CHD incidence, regardless of the substitution nutrients, within the range of intakes in this European population. The opposite direction of associations of SFAs from different food sources such as red meat versus fermented dairy products suggests that public health recommendations should consider foods and overall diets, alongside the macronutrients they contain.

Background: Multiple sclerosis (MS) is a multifactorial disease with unknown etiology. It is assumed to result from interplay between genetic and environmental factors, including nutrition. We hypothesized that there are differences in nutritional parameters between MS patients and healthy controls. Methods: We examined 63 MS patients and 83 healthy controls. Nutritional status was determined by a dietary questionnaire, blood tests, quantification of cell membrane fatty acids, and serum antioxidant capacity. Results: We found that MS patients consumed a more limited diet compared with the healthy group, indicated by a lower average of 31 nutrients and by consumption levels of zinc and thiamine below the recommended daily intake. Both consumption and measured iron values were significantly lower in MS patients, with the lowest measures in the severe MS group. Long saturated fatty acids (>C16) were significantly lower in MS patients, while palmitic and palmitoleic acids were both higher. Serum total antioxidant capacity was significantly lower in the MS group compared with healthy controls, with the lowest measures in patients with severe MS. Conclusions: This study points to a possible correlation between nutritional status and MS. Understanding the clinical meaning of these findings will potentially allow for the development of future personalized dietary interventions as part of MS treatment.

The cAMP dependent protein kinase (PKA) inhibition, haemolytic activity, and cytoxicity of 21 extracts obtained from North Western Australian sponges collected from depths of 84-135 m were investigated. Hexane extracts from Ircinia/Sarcotragus sp. and Geodia sp. displayed PKA inhibitory activities of 100 and 97% respectively (at 100 μg/mL), while aq. methanol extracts from Haliclona sp. exhibited potent haemolytic activity (75%) and hexane extracts from Geodia sp. were highly toxic (88%) to the brine shrimp Artemia franciscana. As the non-polar extracts gave the greatest PKA inhibition, these were further analysed by GCMS and 29 fatty acids were identified in the highest proportions in Ircinia/Sarcotragus sp. > Haliclona sp. > Geodia sp. In contrast to shallow-water sponges that are dominated by polyunsaturated fatty acids with a high percentage of long chain fatty acids, LCFAs (C24-C30), the deep-sea sponges investigated herein were all found to be rich in saturated fatty acids, in particular C14-C20 fatty acids, including odd and branched chain fatty acids, with only low levels (0-10%) of LCFAs. Screening of the PKA inhibitory activity of a series of commercially available fatty acids identified C14-C18 fatty acids as possessing significant PKA inhibitory activity that may contribute to the activity observed in the sponges studied.

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.
