Plant Sterols
Plant sterols are inherent compounds of many nutritional supplements and food additives. Sterols are chemical compounds based on 1,2-cyclopentaneperhydrophenantrene and are characterized by hydroxyl moiety at the 3C position and the side chain at the 17C position. The latter makes them structurally similar to pregnenolone, which is a fundamental molecule for all 17-ketosteroids generation. The major natural source of dietary plant sterols are vegetables, fruits, berries, and vegetable oil.

Dietary Iron
Iron (Fe) is a biochemical microelement important for the health of the population and Fe is necessary for the fetus and all stages of growth individuals. Fe is an essential mineral necessary for delivering oxygen to tissue throughout the body as well as serving important roles in metabolism, respiration, and immune function.  Due to the importance of maintaining Fe stores, even Fe intake meets the recommended daily allowance (RDA), Fe supplementation may be justified, in states of Fe deficiency, with or without anemia, female in particular. The recommended oral Fe supplements are the first line of treatment, however, the bioavailability oral galenic forms is very low and have side effects that reduce tolerance and adherence to treatment.  Thus, a pharmaceutics strategy is to improve the bioavailability of Fe with a bioavailability enhancer.  Some studies indicate that the concomitant use of vitamin C (ascorbic acid), vitamin A, vitamin E, vitamin B9 (folic acid), vitamin B12 (cobalamin) and vitamin D3 (cholecalciferol) increases the bioavailability and absorption of Fe in the intestinal tract.

Dietary Interventions in Attention Deficit Hyperactivity Disorder
Attention Deficit Hyperactivity Disorder (ADHD) is one of the most common neurodevelopmental disorders in childhood, affecting ~7% of children and adolescents. Specific dietary interventions have been proposed as coadjuvant treatments in this disorder. These include nutritional supplements with vitamins, minerals, and polyunsaturated fatty acids; microbiome-targeted interventions with pre-, pro-, and synbiotics; and specific diets such as restriction or elimination diets. Regarding nutritional supplements, only vitamin D and vitamin D + magnesium appear to improve ADHD symptoms when baseline levels of vitamin D are insufficient/deficient. As for biotics, evidence has only been found for Lactobacillus rhamnosus GG and for multi-species probiotic supplementation. Elimination diets have scarce evidence and lead to nutritional deficiencies, so caution is advised.

Resting Metabolic Rate
Resting metabolic rate (RMR) reflects the energy expended by the human body in a prolonged resting state in the absence of food digestion, physical or cognitive activities. RMR declines with age and has been related to changes in body composition and health status. In this study we aimed to assess whether having specific age-associated diseases, or the development thereof, correlate with RMR changes over time. Information on such associations is important to understand the energetic burden of specific diseases and whether early perturbation in energetic metabolism can inform impending health deterioration and future pathology.

Lactobacillus plantarum GKM3
In age-accelerated SAMP8 mouse model, GKM3 groups showed significantly increased latency in the passive avoidance test and time of successful avoidance in the active avoidance test. The TBARS and 8-OHdG from the aged mice brains also showed a significant reduction in the groups treated with GKM3. In addition, lower accumulation of the amyloid-β protein was found in SAMP8 mice brains with the supplement of GKM3. These results indicated that L. plantarum GKM3 delayed the process of aging, alleviated age-related cognitive impairment, and reduced oxidative stress.

Vitamin D Target Genes
The biologically active form of vitamin D3, 1α,25-dihydroxyvitamin D3 (1,25(OH)2D3), modulates innate and adaptive immunity via genes regulated by the transcription factor vitamin D receptor (VDR). In order to identify the key vitamin D target genes involved in these processes, transcriptome-wide datasets were compared, which were obtained from a human monocytic cell line (THP-1) and peripheral blood mononuclear cells (PBMCs) treated in vitro by 1,25(OH)2D3, filtered using different approaches, as well as from PBMCs of individuals supplemented with a vitamin D3 bolus. The led to the genes ACVRL1, CAMP, CD14, CD93, CEBPB, FN1, MAPK13, NINJ1, LILRB4, LRRC25, SEMA6B, SRGN, THBD, THEMIS2 and TREM1. Public epigenome- and transcriptome-wide data from THP-1 cells were used to characterize these genes based on the level of their VDR-driven enhancers as well as the level of the dynamics of their mRNA production.

Lactose Intolerance and Personalized Nutrition
Recent discoveries in the “omics” field and the growing focus on preventive health have opened new avenues for personalized nutrition (PN), which is becoming an important theme in the strategic plans of organizations that are active in healthcare, food, and nutrition research. PN holds great potential for individual health optimization, disease management, public health interventions, and product innovation. However, there are still multiple challenges to overcome before PN can be truly embraced by the public and healthcare stakeholders. The diagnosis and management of lactose intolerance (LI), a common condition with a strong inter-individual component, is explored as an interesting example for the potential role of these technologies and the challenges of PN. From the development of genetic and metabolomic LI diagnostic tests that can be carried out in the home, to advances in the understanding of LI pathology and individualized treatment optimization, PN in LI care has shown substantial progress. However, there are still many research gaps to address, including the understanding of epigenetic regulation of lactase expression and how lactose is metabolized by the gut microbiota, in order to achieve better LI detection and effective therapeutic interventions to reverse the potential health consequences of LI.

Deadly Helminthiasis
Helminthiasis is an expensive management problem in sheep and goat industry, because the gastrointestinal parasites develop resistance against all anthelmintic chemical products which are discovered and produced by the pharmaceutical industry. The use of natural tannin containing forages such as Sericea Lespedeza is highly promising. Helminthiasis is the invasion of internal parasites into the GI tract of domestic animals, even in humans, causing serious deadly consequences. Sheep and goats are more seriously afflicted than other farm animals. Helminthiasis results in high mortality rate, and poor growth rates, low reproductive performances and low quality products produced from infected animals, which increase high production costs. Anthelmintic drug has been used as the most common control method against gastrointestinal nematodes (GIN) infection. Overuse and misuse of these drugs caused significant GIN resistance against the drugs, especially in sheep and goat production.

Dietary Macronutrients That Prompt MetS via Mitochondria
Metabolic syndrome (MetS) is a cluster of metabolic risk factors for diabetes, coronary heart disease, non-alcoholic fatty liver disease, and some tumors. It includes insulin resistance, visceral adiposity, hypertension, and dyslipidemia. MetS is primarily linked to lipotoxicity, with ectopic fat deposition from fat storage exhaustion, more than obesity per se. Excessive intake of long-chain saturated fatty acid and sugar closely relates to lipotoxicity and MetS through several pathways, including toll-like receptor 4 activation, peroxisome proliferator-activated receptor-gamma regulation (PPARγ), sphingolipids remodeling, and protein kinase C activation. These mechanisms prompt mitochondrial dysfunction, which plays a key role in disrupting the metabolism of fatty acids and proteins and in developing insulin resistance.

Cyrcadian Rhythm, Mood, and Temporal Patterns of Chocolate
Taking small amounts of chocolate, in the morning at breakfast at the onset of the active phase, helps speed up resynchronization time. The high flavonoid contents in chocolate promote cardioprotection, metabolic regulation, neuroprotection, and neuromodulation with direct actions on brain function, neurogenesis, angiogenesis, and mood. Cocoa products and especially chocolate are foodstuffs originating from South America. Cocoa is obtained from the seeds of the Theobroma cacao tree, which are then dried, shelled, fermented, and ground with other substances such as sugar, fat, and other flavorings to produce the wide variety of chocolate available on the market, from dark to milk variations.

Modified Citrus Pectin Pleiotropic Effects
Modified citrus pectin (MCP) has a low-molecular-weight degree of esterification to allow absorption from the small intestinal epithelium into the circulation. MCP produces pleiotropic effects, including but not limited to its antagonism of galectin-3, which have shown benefit in preclinical and clinical models. Regarding cancer, MCP modulates several rate-limiting steps of the metastatic cascade. MCP can also affect cancer cell resistance to chemotherapy. Regarding fibrotic diseases, MCP modulates many of the steps involved in the pathogenesis of aortic stenosis. MCP also reduces fibrosis to the kidney, liver, and adipose tissue. Other benefits of MCP include detoxification and improved immune function.

Polyphenols and Muscle Atrophy
Skeletal muscle atrophy is the decrease in muscle mass and strength caused by reduced protein synthesis/accelerated protein degradation. Various conditions, such as denervation, disuse, ageing, chronic diseases, heart disease, obstructive lung disease, diabetes, renal failure, AIDS, sepsis, cancer, and steroidal medications, can cause muscle atrophy. Mechanistically, inflammation, oxidative stress, and mitochondrial dysfunction are among the major contributors to muscle atrophy, by modulating signalling pathways that regulate muscle homeostasis. To prevent muscle catabolism and enhance muscle anabolism, several natural and synthetic compounds have been investigated. Recently, polyphenols (i.e., natural phytochemicals) have received extensive attention regarding their effect on muscle atrophy because of their potent antioxidant and anti-inflammatory properties. Numerous in vitro and in vivo studies have reported polyphenols as strongly effective bioactive molecules that attenuate muscle atrophy and enhance muscle health.

Krill Oil
Krill (Euphausia superba) is a small marine crustacean from the Antarctic Ocean that plays an important role in the marine ecosystem, serving as feed for most fish. It is a known source of highly bioavailable omega-3 polyunsaturated fatty acids (eicosapentaenoic acid and docosahexaenoic acid). In preclinical studies, krill oil showed metabolic, anti-inflammatory, neuroprotective and chemo preventive effects, while in clinical trials it showed significant metabolic, vascular and ergogenic actions. Solvent extraction is the most conventional method to obtain krill oil. However, different solvents must be used to extract all lipids from krill because of the diversity of the polarities of the lipid compounds in the biomass.

Anthocyanins in Whole Grain Cereals
Anthocyanins are water-soluble phenolic pigments responsible for red, purple, blue, or even black colours in fruits, vegetables, grains, flowers, and other pigmented plant tissues. All anthocyanins share the same core structure, a flavylium ion, consisting of two aromatic ring structures linked by a three-carbon heterocyclic ring that contains oxygen. The anthocyanidin (aglycone form) is the core structure of the anthocyanin. The addition of a sugar side chain results in the glycosidic form of the anthocyanidin molecule, called an anthocyanin.

Dietary Nitrates in Sports Nutrition
Higher intake of nitrates from the diet can increase the bioavailability of nitric oxide (NO) via the nitrate–nitrite–NO pathway. Increased production of NO (e.g., in mitochondria, blood vessel cells, muscle cells) may improve physical performance. Nevertheless, the increased availability of NO via daily diet or supplementation does not always lead to improved performance in some individuals. Research observations suggest there might be fibre-type specific effects of dietary nitrates (DN) intake. It seems that ergogenicity is somehow related to the fibre-type ratio in muscles, augmenting the exercise economy and performance more likely via type II muscle fibres than type I. Therefore, more consistent and positive improvements in physical performance are usually observed in less-trained athletes (VO2max <65 mL/min/kg) or untrained. Statistically non-significant effects on performance are less likely observed in well-trained and elite endurance-trained athletes (VO2max >65 mL/min/kg). It is also essential to follow the correct supplementation plan (acute/chronic use) to enhance exercise economy or performance, whereas the chronic use of DN brings more consistent results. Nevertheless, DN offer easily available, safe and efficient ergogenic aid for some athletes who seek to improve their performance.
