This study is investigating whether a new type of fish oil supplement, in the form of soft chews, leads to better absorption of omega-3s in the body compared to traditional fish oil capsules. Omega-3s, found in fish oil, are known to support heart health and reduce inflammation, but they may absorb better in certain forms. In this study, participants will take both types of supplements (soft chews and capsules) at different times to compare how well the omega-3s are absorbed. Researchers will measure the levels of omega-3s in the blood over several hours to determine if the soft chews offer a better option for people seeking the health benefits of omega-3s.

The long-chain polyunsaturated fatty acids (PUFA) of the n-3 or omega-3 series and, in particular, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), both derived from the essential fatty acid alpha-linolenic acid, are part of all cell membranes and from them derive numerous compounds such as prostaglandins, thromboxanes, leukotrienes, resolvins, protectins and maresins that play numerous biological roles, most notably in the control of body homeostasis, blood coagulation and inflammation. The omega-3 index is a biomarker that reflects the nutritional status of n-3 PUFA, as well as cardiometabolic risk and cardiovascular health. This index is determined as the sum of the percentages in weight of EPA and DHA over the total of fatty acids present in the erythrocyte membranes. Previous studies carried out in Spain, such as ANIBES, indicate that in adults, and especially in those over 60 years of age, the intake of n-3 PUFA is well below the international recommendations, which is directly related to a low intake of fish, since both EPA and DHA are abundant in oily fish. However, in Spain, the nutritional status of omega-3 PUFA and their possible association with a higher prevalence of cardiometabolic risk is unknown, as well as the relationships with food intake and the cultural and socioeconomic status of the population. Therefore, the main objective of the present study is to evaluate the omega-3 index in the Spanish population over 60 years of age and to establish whether there are differences by sex, as well as in the different Spanish communities. In addition, we will study the possible associations between the omega-3 index and food intake, particularly of fish and omega-3 PUFA-rich supplements, as well as their possible associations with cardiometabolic risk indicators and cultural and socioeconomic conditions of the population. Determination of the omega-3 index usually requires an invasive venous blood collection followed by processing for separation of erythrocytes and extraction and methylation of their membrane lipids followed by chromatographic analysis. But fatty acids can also be determined on whole blood using less invasive methods, such as obtaining drops of blood with a lancet and depositing them on chromatographic paper impregnated with an antioxidant (dried spots). All this makes sampling much easier, although the result of the omega-3 index has to be corrected because it is affected by the lipid composition present in the plasma. For this reason, this project aims to carry out a validation study between the results of the fatty acid profile obtained in erythrocytes and in whole blood in the Spanish population (medamediantedried spots). In short, the results obtained will be used to calculate regression lines that allow us to evaluate the omega-3 index in erythrocytes in the adult Spanish population from different regions of Spain by means of a minimally invasive methodology. For this purpose, 800 participants aged 60 years or more will be recruited from different regions of Spain, randomized by age and sex for each region; at least 100 of the total number of participants should be frequent consumers of omega-3 supplements; if this figure is not obtained, an active search will be carried out until this number is reached (booster). All of them will be interviewed to complete different questionnaires on cultural and socioeconomic status, history of metabolic disease and cardiovascular health, and questionnaires on frequency of consumption and food intake reminders as established by the European Union. With the help of health personnel from different pharmacies and in mutual agreement with the General Council of Pharmaceutical Associations of Spain, a whole blood sample will be taken by lancet, which will be used to quantify the omega-3 index. For the validation study it will be necessary to obtain whole venous blood extracted by venipuncture from a subsample of 200 participants. This sample will be processed and will be used to determine the fatty acid profile in whole blood and in erythrocytes, which will be related by means of multiple linear and bivariate regression models with the fatty acid profile obtained in the dried spots. Cardiometabolic risk markers will also be determined in these 200 subjects, which will be used to establish relationships with the calculated omega-3 status.

Data linking fish, polyunsaturated fatty acids intake and mortality are lacking and conflicting. We aim to use data from the China Health and Nutrition Survey (CHNS) and National Health and Nutrition Examination Survey (NHANES) to investigate the associations of fish and polyunsaturated fatty acids (PUFA) intake with mortality in Chinese and US populations. The study findings will be informative for addressing the role of fish and specific PUFA in human health and improve basis for dietary recommendations.

Current research on the pathogenesis of depression shows that imbalanced inflammatory factors are closely related to Major Depressive Disorder(MDD). As reported, physical exercise, Ω-3 fatty acids, and sulforaphane can be complementary therapies for moderate-to-severe depression. In addition, imaging studies have found changes in the structure and functional connectivity of the brain. Therefore, this study intends to collect clinical and biological information from patients with depression and healthy controls to establish a multi-factor model for early warning and diagnosis of major depressive disorder

Essential polyunsaturated fatty acids (EFAs) have a significant impact on human health, even before birth. Their supplementation is recommended at all ages, especially in people with cardiolovascular risks. The most valuable proven action of EFAs is the improvement of the lipid profile (including increase in HDL, the so-called "good cholesterol" and lowering LDL, the so-called "bad cholesterol"), preventing the development of atherosclerosis, strokes and heart attacks. We distinguish three fractions of EFAs: EPA, DHA and ALA. The best known are EPA and DHA, but in recent years the interest in ALA fraction has increased, as it is the only fraction that has pronounced anti-inflammatory properties, but also only ALA is not produced by the human body and must be supplied with food. We believe that the supplementation of the ALA fraction is as important as the supplementation of the well-known and recommended EPA and DHA fractions, moreover it also brings unique benefits. The aim of the study is to demonstrate the benefits of EFAs in the prevention of cardiovascular diseases in the group of adults. In the project, we also want to compare the benefits of supplementing various fractions. Each volunteer will be randomly assigned to one of 4 groups. Group No. 1 will be a group without the supplementation of essential fatty acids (EFAs), group No. 2 will receive supplementation with pure ALA fraction, group No. 3 will receive supplementation with EPA and DHA fractions, and group No. 4 will receive supplementation with all fractions, i.e. ALA, EPA and DHA. All persons from groups 1-4 will be examined three times: at the beginning, after three months and after six months (at the end of the project). The tests will include: blood pressure measurements, non-invasive measurements of body mass and composition, and laboratory tests: CRP, fasting glucose, lipid profile, and blood count. Both preparations for acid supplementation and tests are completely free for participants. Participation in the study is voluntary and is not associated with any health risk.

The epidemic of pediatric obesity has become a public health burden in both developed and developing countries, due to its serious health consequences, including an increased risk of type 2 Diabetes Mellitus and heart disease. Currently, dietary and exercise changes are still the center of preventive and treatment measures of obesity. Recently, the omega-3 group, one of the groups of polyunsaturated fatty acids (PUFAs), has been associated with many positive effects leading to the improvement of many diseases related to obesity. Nevertheless, the consumption of this essential nutrient requires certain ration to optimize its favorable result. Although previous studies have examined the efficacy of dietary counseling approach as treatment for obesity, none of them as explicitly explore the use of linear programming to create a tailored diet containing high omega-3 fatty acid food as a part of dietary counseling in obesity management program among children. Thus, this study is intended to contribute the clinical evidence regarding this area of knowledge, specifically the effects of enhanced counseling containing complementary feeding recommendation on nutritional status, omega-3 fatty acid, malondialdehyde, and alpha Tocopherol among children with risk of overweight aged 12 -23 months in East Jakarta.

Previous studies have shown that omega-3 fatty acid pills intake have beneficial effect on vascular health in overweight and/or hypertensive patients. However, there is a lack of studies showing the effect of everyday consumption of omega-3 fatty acids enriched food (not pills) on lipid profile and microvascular reactivity in healthy population. This study aimed to determine the effect of omega-3 enriched chicken eggs consumption on microvascular reactivity and lipid profile in young healthy subjects.

Many studies in the past three decades have examined the beneficial effects of omega-3 polyunsaturated fatty acids in diet and supplementation. The effect of polyunsaturated fatty acids, specifically omega-3 and omega-6, on health have been well-studied but most of the study to date has been on animal not plant sources and much less is know about their effects on exercise performance. Additionally, while positive effects have been detected for sedentary populations or those that are at risk, well-trained athletes generally have not had established advantages in taking supplements for omega-3 and omega-6 oils. There is evidence that a specific ratio of omega-6 to omega-3 is most beneficial for the human body with regards to cardiovascular and mental health. In this study, participants randomized to either a plant supplement group (pureform omega; containing Flax, Evening Primrose, Sunflower, Coconut \& Pumpkin oils; Natural Product Number = 80050660) or placebo (isoenergetic sugar pills) will be subjected to both a time trial and a high intensity interval bout, where their performance and power output will be analyzed. Blood lactate and glucose concentration, as well as oxygen consumption and carbon dioxide production will also be examined to determine if there is a change in on fat oxidation after supplementation.

The incidence of acute pancreatitis in UK has risen sharply over the past 40 years. Recent reports suggest that 56.5 per 100 000 of the population will suffer from AP annually; this figure is more than double the highest previous estimated incidence. In the majority of patients the condition is mild, but about 25% of patients suffer a severe attack and between 30 and 50% of these patients dies. The usual cause of death is multiple organ failure secondary to systemic leukocyte activation (mainly neutrophils), accompanied by the systemic inflammatory response syndrome (SIRS). Studies with omega-3 fish oil have shown to control inflammatory process and improve the outcome especially in hyperinflammatory conditions. This research will look at the effects of supplementing omega-3 fish oil to patients with severe acute pancreatitis (severe inflammation of the pancreas). Patients with severe acute pancreatitis will be prospectively and blindly randomised into either a study group who will receive (Lipidem, lipid emulsion contains essential fatty acids and omega-3 fish oil) or a control group that will receive (Lipofundin, lipid emulsion contains only essential fatty acids and no omega-3 fish oil). Normal and standard clinical care will be provided to all patients as per the national management guidelines. Each patient will receive either Lipidem or Lipofundin emulsions daily until they are deemed fit for discharge by their own medical team or for a maximum of SEVEN days. The main aim of this study is to examine whether lipid emulsions enriched with omega-3 fish oil could improve the clinical outcome in patients with severe acute pancreatitis.

The biological membranes that surround a cell and its organelles are important to the overall function of the cell. Fatty acids are the main structural components of a membrane, and the presence of certain fatty acids can alter a membrane's characteristics, which subsequently alters its function. Two fatty acids that are of particular interest to researchers are eicosapentanoic acid (EPA) and docosahexanoic acid (DHA). These omega-3 fatty acids have unique unsaturated structures, and their incorporation into biological membranes appears to elicit potent physiological effects. The body is unable to intrinsically synthesize these important fatty acids, so they must be obtained from the diet or through supplementation. EPA and DHA supplementation has been reported to provide numerous positive health benefits, including decreased blood pressure and an improved blood lipid profile. Recent research in our laboratory has demonstrated in young men that resting metabolic rate was increased following a 12 week period of omega fatty acid supplementation of 3 g/day. Fat utilization was also increased and carbohydrate use was decreased both at rest and during a 1 hr moderate exercise challenge. These findings have positive implications for people who are interested in losing weight, but it not known whether these effects occur in older adults. With age, body composition changes (increase in fat mass and decrease in lean mass) occur which may negatively affect general health, particularly normal physical functioning and quality of living of the older adult. The potential role of omega 3 fatty acids to increase fat oxidation and increase resting metabolic rate may be a therapy for decreasing fat mass in the older adult. Research has suggested that omega 3 fatty acids may elicit an additional therapeutic role by reducing joint pain. Another aspect of aging is a loss in lean body mass, which is associated with an attenuation of skeletal muscle protein synthesis in response to nutritional stimuli (amino acids and insulin). The weakened anabolic response is considered to be partly due to defects in the anabolic signaling cascade in the muscle. Research in older adults has reported an increase in muscle protein signaling with EPA and DHA supplementation in response to a nutritional challenge. However it is unknown whether the increase in protein signaling results in an eventual increase in lean body mass. The physical functioning of older adults is not only influenced by body composition changes, but also age-related neuronal changes that affect the velocity of axonal conduction and influence the ability of the muscle to generate torque and the rate at which the torque is developed. Muscular strength and functional capacity increases have been reported with chronic resistance exercise in a cohort of older women supplemented with EPA and DHA. However, the effect of EPA and DHA intake on physical strength in older adults with previously low EPA and DHA consumption, independent of exercise, is currently unknown. Therefore, the purpose of this study is to determine the effects of 12 weeks of omega-3 supplementation at 3 g/day on metabolic and physical health parameters in community-dwelling older adults. We hypothesize that EPA and DHA supplementation will result in 1) a decrease in resting heart rate and blood pressure; 2) a more healthy blood profile; 3) an increase in resting metabolic rate; 4) a greater reliance on fat oxidation for energy both at rest and during exercise; and 5) a decrease in fat mass; and 6) an increase in lean mass, strength and physical function.

This is a randomized, double-blind, placebo controlled, cross-over, single centre, 14 week clinical trial on healthy volunteers. Following a two week run-in-period, subjects were randomized, and treatment with synbiotic or placebo for 21 days was given, followed by a 3-week wash-out period before the second treatment period, followed by a another wash-out period. Volunteers completed questionnaires for each period on overall health and well being, stool frequency and consistency and gastrointestinal symptoms. The subjects were asked to collect fecal samples for investigation of microbiological and microbial metabolites before and after three treatment periods. The primary objective of the study is tan increase in fecal butyrate concentration. Secondary objectives are changes in microbiota composition and short-chain fatty acids.
