Plant seeds have gained interest for their health benefits due to their fatty acid content. The objective of this study was to determine the effects of dietary consumption of milled sesame/pumpkin/flax seed mixture on glycemic control, serum lipids, phospholipid fatty acid status, and inflammatory factors in patients on hemodialysis.
Thirty patients with well nutrition status (18 male, 12 female) were enrolled in the study. Participants consumed 30â€‰g of milled sesame/pumpkin/flax (6â€‰g/6â€‰g/18â€‰g, resp.) seeds mixture added to their habitual diet.
Total n-6 and n-3 polyunsaturated fatty acids and levels of linoleic, dihomo-gamma-linolenic (DGLA), arachidonic, alpha-linolenic (ALA), eicosapentaenoic, docosapentaenoic, and docosahexaenoic (DHA) acid were increased after 12 weeks of supplementation. A significant decrease of the serum triglyceride level (P < 0.001), glucose, insulin, calculated IR HOMA (P < 0.05), and inflammatory markers (TNF-alpha, IL-6, and hs-CRP, P < 0.001) was observed after seed mixture treatment. The serum levels of CRP and TNF-alpha negative correlate with ALA, DHA, and DGLA.
Results of this study indicated that dietary milled sesame/pumpkin/flax seed mixture added to a habitual diet lowered triglyceride and CRP, TNF-alpha, IL-6 levels, affect glycemic control and improved fatty acid profile and pruritus symptoms in hemodialysis patients.
Hempseed oil is a rich and balanced source of omega-6 and omega-3 polyunsaturated fatty acids (PUFAs). Anecdotal evidence indicated that dietary hempseed oil might be useful in treating symptoms of atopic dermatitis.
PATIENTS AND METHODS:
Dietary hempseed oil and olive oil were compared in a 20-week randomized, single-blind crossover study with atopic patients. Fatty acid profiles were measured in plasma triglyceride, cholesteryl and phospholipid fractions. A patient questionnaire provided additional information on skin dryness, itchiness and usage of dermal medications. Skin transepidermal water loss (TEWL) was also measured.
Levels of both essential fatty acids (EFAs), linoleic acid (18:2n6) and alpha-linolenic acid (18:3n3), and gamma-linolenic acid (GLA; 18:3n6) increased in all lipid fractions after hempseed oil, with no significant increases of arachidonic acid (20:4n6) in any lipid fractions after either oil. Intra-group TEWL values decreased (p=0.074), qualities of both skin dryness and itchiness improved (p=0.027) and dermal medication usage decreased (p=0.024) after hempseed oil intervention.
Dietary hempseed oil caused significant changes in plasma fatty acid profiles and improved clinical symptoms of atopic dermatitis. It is suggested that these improvements resulted from the balanced and abundant supply of PUFAs in this hempseed oil.
Background: Multiple sclerosis (MS) is the most chronic and inflammatory disorder. Because of limited efficacy and adverse side effects, identifying novel therapeutic and protective agents is important. This study was aimed to assess the potential therapeutic effects of hemp seed and evening primrose oils as well as Hot-nature dietary intervention on RRMS patients.
METHODS AND MATERIALS:
In this double blind, randomized trial, 100 MS patients with EDSS<6 were allocated into 3 groups: "Group A" who received co-supplemented hemp seed and evening primrose oils with advised Hot-nature diet, "Group B" who received olive oil, "Group C" who received the co-supplemented oils. Mizadj, clinically EDSS and relapse rate as well as immunological factors (IL-4, IFN-Îł and IL-17) were assessed at baseline and after 6 months.
Mean follow-up was 180Â±2.9 SD days (N=65, 23 M and 42 F aged 34.25Â±8.07 years with disease duration 6.80Â±4.33 years). There was no significant difference in studies parameters at baseline. After 6 months, significant improvements in Mizadj, EDSS and relapse rate were found in the groups A and C, while the group B showed a border significant decrease in relapse rate. Immunological parameters showed improvement in groups A and C, whereas there was worsening condition for group B after the intervention.
The co-supplemented hemp seed and evening primrose oils with Hot-nature diet have beneficial effects in improving of clinical score in RRMS patients which were confirmed by immunological findings.

Resveratrol in high doses has been shown to extend lifespan in some studies in invertebrates and to prevent early mortality in mice fed a high-fat diet. We fed mice from middle age (14-months) to old age (30-months) either a control diet, a low dose of resveratrol (4.9 mg kg(-1) day(-1)), or a calorie restricted (CR) diet and examined genome-wide transcriptional profiles. We report a striking transcriptional overlap of CR and resveratrol in heart, skeletal muscle and brain. Both dietary interventions inhibit gene expression profiles associated with cardiac and skeletal muscle aging, and prevent age-related cardiac dysfunction. Dietary resveratrol also mimics the effects of CR in insulin mediated glucose uptake in muscle. Gene expression profiling suggests that both CR and resveratrol may retard some aspects of aging through alterations in chromatin structure and transcription. Resveratrol, at doses that can be readily achieved in humans, fulfills the definition of a dietary compound that mimics some aspects of CR.
Caloric restriction (CR) without malnutrition increases longevity and delays the onset of age-associated disorders in short-lived species, from unicellular organisms to laboratory mice and rats. The value of CR as a tool to understand human ageing relies on translatability of CR's effects in primates. Here we show that CR significantly improves age-related and all-cause survival in monkeys on a long-term ~30% restricted diet since young adulthood. These data contrast with observations in the 2012 NIA intramural study report, where a difference in survival was not detected between control-fed and CR monkeys. A comparison of body weight of control animals from both studies with each other, and against data collected in a multi-centred relational database of primate ageing, suggests that the NIA control monkeys were effectively undergoing CR. Our data indicate that the benefits of CR on ageing are conserved in primates.
