Dietary Interventions for Complementing Celiac Disease and Beyond
Celiac Disease (CeD) is a chronic small intestinal immune-mediated enteropathy caused by ingesting dietary gluten proteins in genetically susceptible individuals. CeD is one of the most common autoimmune diseases, affecting around 1.4% of the population globally. The only acceptable treatment for CeD is strict, lifelong adherence to a gluten-free diet (GFD). However, in some cases, GFD does not alter gluten-induced symptoms. In addition, strict adherence to a GFD reduces patients’ quality of life and is often a socio-economic burden. Therefore, dietary and non-dietary interventions are investigated. This entry concentrates on the recent research on the degradation of gluten through enzymes, the modulation of the microbiome, and the different types of “biotics” strategies, from probiotics to the less explored “viromebiotics” as possible beneficial complementary interventions for CeD management and other less understood gluten-related disorders beyond the GFD.

IDA in Celiac Disease
The iron absorption process develops mainly in the proximal duodenum. This portion of the intestine is typically destroyed in celiac disease (CD), resulting in a reduction in absorption of iron and subsequent iron deficiency anemia (IDA). In fact, the most frequent extra-intestinal manifestation (EIM) of CD is IDA, with a prevalence between 12 and 82% (in relation with the various reports) in patients with new CD diagnosis. The primary treatment of CD is the gluten-free diet (GFD), which is associated with adequate management of IDA, if present. Iron replacement treatment historically has been based on oral products containing ferrous sulphate (FS). However, the absorption of FS is limited in patients with active CD and unpredictable in patients on a GFD. Furthermore, a poor tolerability of this kind of ferrous is particularly frequent in patients with CD or with other inflammatory bowel diseases. Normalization from anemic state typically occurs after at least 6 months of GFD, but the process can take up to 2 years for iron stores to replenish.

Preventing Obesity among Adolescents
Some authors do understand that the concept of obesity must be a combination of at least BMI over the second standard deviation for age and gender, with some body composition evaluation, as waist/height relation, neck circumference or physical methods to analyse fat deposition (absorciometry or pletismography, and in more debatable concerns impedanciometer (tetrapolar ), skin folder measurements or summ of perimeters.

Protein Intake and Single-Nephron GFR
High protein intake can increase glomerular filtration rate (GFR) in response to excretory overload, which may exacerbate the progression of kidney disease. However, the direct association between glomerular hemodynamic response at the single-nephron level and dietary protein intake has not been fully elucidated in humans. In the present study, we evaluated nutritional indices associated with single-nephron GFR (SNGFR) calculated based on corrected creatinine clearance (SNGFRCr). We retrospectively identified 43 living kidney donors who underwent enhanced computed tomography and kidney biopsy at the time of donation at Jikei University Hospital in Tokyo from 2007 to 2018. Total nephron number was estimated with imaging-derived cortical volume and morphometry-derived glomerular density. SNGFRCr was calculated by dividing the corrected creatinine clearance by the number of non-sclerosed glomeruli (NglomNSG). The mean (± standard deviation) NglomNSG/kidney and SNGFRCr were 685 000 ± 242 000 and 61.0 ± 23.9 nL/min, respectively. SNGFRCr was directly associated with estimated protein intake/ideal body weight (P = 0.005) but not with body mass index, mean arterial pressure, albumin, or sodium intake. These findings indicate that greater protein intake may increase SNGFR and lead to glomerular hyperfiltration.

Nutrients and Postmenopausal Osteoporosis
Osteoporosis is a debilitating disease that is worsened post-menopause due to oestrogen loss.  The objective of this review was to investigate nutrient and dietary patterns that have been reported to be beneficial for bone health in postmenopausal women. We found calcium, vitamin D, B-vitamins, potassium, phosphorus, magnesium, vitamin C, and vitamin K are important nutrient requirements for bone health while foods such as low-fat dairy (including milk, yoghurt, and cheese), fish (with bones), fortified and fruits and vegetables are important for bone health maintenance.

Nutrition-Based Interventions and Menstrual Cycle
Despite the steady increase in female participation in sport over the last two decades, comprehensive research on interventions attenuating the influence of female menstrual physiology on performance remains scarce. Studies involving eumenorrheic women often only test in one menstrual phase to limit sex hormone variance, which may restrict the application of these findings to the rest of the menstrual cycle. The impacts of nutrition-based interventions on athletic performance throughout the menstrual cycle have not been fully elucidated. We addressed this gap by conducting a focused critical review of clinical studies that reported athletic outcomes as well as menstrual status for healthy eumenorrheic female participants. In total, 1443 articles were identified, and 23 articles were included.

Nutriepigenomics in Environmental-Associated Oxidative Stress
Complex molecular mechanisms define our responses to environmental stimuli. Beyond the DNA sequence itself, epigenetic machinery orchestrates changes in gene expression induced by diet, physical activity, stress and pollution, among others. Importantly, nutrition has a strong impact on epigenetic players and, consequently, sustains a promising role in the regulation of cellular responses such as oxidative stress. As oxidative stress is a natural physiological process where the presence of reactive oxygen-derived species and nitrogen-derived species overcomes the uptake strategy of antioxidant defenses, it plays an essential role in epigenetic changes induced by environmental pollutants and culminates in signaling the disruption of redox control.

Dietary Fibers in Inflammatory Bowel Diseases
Inflammatory bowel diseases (IBDs) are chronic, progressive, immune-mediated diseases of the intestinal tract. The main subtypes of IBDs are Chron’s disease (CD) and ulcerative colitis (UC). The etiology is still unclear, but there are genetic, environmental and host-related factors that contribute to the development of these diseases. Literature has shown that dietary therapy is the cornerstone of IBD treatment in terms of management of symptoms, relapse and care of the pathology. IBD patients show that microbiota dysbiosis and diet, especially dietary fiber, can modulate its composition. These patients are more at risk of energy protein malnutrition than the general population and are deficient in micronutrients. So far, no dietary component is considered responsible for IBD and there is not a specific therapeutic diet for it.

Dietary Polyphenols and NAFLD
Non-Alcoholic Fatty Liver Disease (NAFLD) is a clinical condition primarily characterized by fat accumulation in liver parenchyma (>5% of hepatocytes). Its clinical burden is encompassed in its pathologic spectrum, which ranges from simple fatty liver (Simple Fatty Liver – SFL) to steato-hepatitis (Non-Alcoholic Steatohepatitis – NASH), ending with hepatic cirrhosis and hepatocarcinoma, through a progressive fibrosis of the organ. These advanced stages are associated with higher mortality, but all stages of NAFLD can significantly increase the risk of cardiovascular diseases since these are the most prevalent clinical features in NAFLD.

Functional Food Ingredients for Viral Diseases
A complex network of processes within the human immune system provides resistance to a variety of disease states. This defense forms innate and adaptive immunity, with specific immune components working together to combat infection. In addition to genetic variables, susceptibility to disease can be influenced by factors such as lifestyle, age and environmental factors. Certain food chemicals have been shown to modulate signaling and cell morphology. This has implications for pathophysiology. Eating some functional foods can increase the activity of immune cells and protect us from various diseases, including those caused by viruses as discussed below.

DHA Supplementation during Pregnancy
Docosahexaenoic acid (DHA) supplementation during pregnancy has been recommended by several health organizations due to its role in neural, visual, and cognitive development. There are several fat sources available on the market for the manufacture of these dietary supplements with DHA. These fat sources differ in the lipid structure in which DHA is esterified, mainly phospholipids (PL) and triglycerides (TG) molecules. The supplementation of DHA in the form of PL or TG during pregnancy can lead to controversial results depending on the animal model, physiological status and the fat sources utilized. The intestinal digestion, placental uptake, and fetal accretion of DHA may vary depending on the lipid source of DHA ingested by the mother. The form of DHA used in maternal supplementation that would provide an optimal DHA accretion for fetal brain development, based on the available data obtained most of them from different animal models, indicates no consistent differences in fetal accretion when DHA is provided as TG or PL. Other related lipid species are under evaluation, e.g., lyso-phospholipids, with promising results to improve DHA bioavailability although more studies are needed. In this review, the evidence on DHA bioavailability and accumulation in both maternal and fetal tissues after the administration of DHA supplementation during pregnancy in the form of PL or TG in different models is summarized.

Human and Donkey Milk
Whole milk is a good source of all the nutrients, and it also contains a sufficient number of vitamins to permit the regular growth of the neonate. Dairy cow milk can create allergy in infants less than 12 months old because of the high caseins and β-lactoglobulin content. In these circumstances, donkey milk can represent a good replacement for dairy cows’ milk in children affected by Cow Milk Protein Allergy (CMPA) because of its close chemical composition with human milk, mainly due to its low protein and low mineral content.

Vitamin K2 in “Bone-Vascular Crosstalk”
Osteoporosis (OP) and vascular calcification (VC) represent relevant health problems that frequently coexist in the elderly population. Traditionally, they have been considered independent processes, and mainly age-related. However, an increasing number of studies have reported their possible direct correlation, commonly defined as “bone-vascular crosstalk”. Vitamin K2 (VitK2), a family of several natural isoforms also known as menaquinones (MK), has recently received particular attention for its role in maintaining calcium homeostasis.

VitD and Autoimmune Thyroid Disease
Vitamin D is a steroid hormone traditionally connected to phosphocalcium metabolism. The discovery of pleiotropic expression of its receptor and of the enzymes involved in its metabolism have led to exploration of the other roles of this vitamin, namely on autoimmune thyroid disease. Most of the existing data support a relationship between vitamin D deficiency and a greater tendency for development and/or higher titers of antibodies linked to Hashimoto's thyroiditis, Graves' disease, and/or postpartum thyroiditis. The nature of this relationship is yet unknown, it may be due to vitamin D's immunoregulatory role, emerge as a consequence of the autoimmune disease, or be a result physiopathological process underlying the autoimmune disease. Our thesis is that, due to its immunoregulatory role, vitamin D plays a minor role in conjunction with myriad other factors. In some cases, a vicious cycle is generated, thus contributing to the deficiency and aggravating the autoimmune process.

Legume Consumption
Legumes are nutrient-dense crops with health-promoting benefits. However, several barriers are associated with their consumption. Emerging issues including food neophobic tendencies or taboos, unclear dietary guidelines on legume consumption, health concerns, and socio-economic reasons, as well as long cooking procedures, adversely affect legume consumption frequency. Pre-treatment methods, including soaking, sprouting, and pulse electric field technology, are effective in reducing the alpha-oligosaccharides and other anti-nutritional factors, eventually lowering cooking time for legumes.
