Background: Diarrhea and malnutrition are major health problems in developing countries. Inflammation, high oxidative stress, poor nutritional status, and fatty liver were encountered during such diseases. Patents for diarrhea and malnutrition management (WO2007/130882A2, WO00/37106A1, WO2014/152420, and CA2987364A1) were published. Objective: The objective was to introduce anti-diarrhea functional foods with a preventive effect on malnutrition. Methods: Two processing techniques were applied for preparing functional foods (formula 1 ingredients were made into cookies followed by grinding; formula 2 ingredients were pre-cooked, dried, and mixed in powder form) that were evaluated in a rat model of diarrhea with malnutrition (DM). Formula 2 was also assessed when mixed with nucleotides. The ingredients were edible plants that possess an anti-diarrheal effect with high protein sources (legumes and casein). Results: Induction of diarrhea with malnutrition, high oxidative stress, inflammation, accumulation of liver fat, and histopathological changes were demonstrated in DM control compared to normal control. The functional foods produced variable improvement in growth curves, food efficiency ratio, hemoglobin, hematocrit and plasma zinc, protein, albumin, globulin, lipase activity, and MDA. Formula 1 was superior in improving intestinal histopathology while formula 2 was more efficient in elevating plasma iron. Formula 2 with nucleotides was the best in improving growth curves, alkaline phosphatase, and reducing liver fat. Intestinal mucosa reduced glutathione and nitrite showed an efficient significant reduction on treatment with formula 2 with or without nucleotides. The formulas showed an anti-diarrheal effect by improving feces weight and moisture content. Conclusion: Studied functional foods showed an anti-diarrheal effect and malnutrition improvement with different degrees.

Chronic excessive alcohol consumption is associated with multiple liver defects, such as steatosis and cirrhosis, mainly attributable to excessive reactive oxygen species (ROS) production. Barley sprouts (Hordeum vulgare L.) contain high levels of polyphenols that may serve as potential antioxidants. This study aimed to investigate whether barley sprouts extract powder (BSE) relieves alcohol-induced oxidative stress and related hepatic damages in habitual alcohol drinkers with fatty liver. In a 12-week randomized controlled trial with two arms (placebo or 480 mg/day BSE; n = 76), we measured clinical markers and metabolites at the baseline and endpoint to understand the complex molecular mechanisms. BSE supplementation reduced the magnitude of ROS generation and lipid peroxidation and improved the glutathione antioxidant system. Subsequent metabolomic analysis identified alterations in glutathione metabolism, amino acid metabolism, and fatty acid synthesis pathways, confirming the role of BSE in glutathione-related lipid metabolism. Finally, the unsupervised machine learning algorithm indicated that subjects with lower glutathione reductase at the baseline were responders for liver fat content, and those with higher fatigue and lipid oxidation were responders for γ-glutamyl transferase. These findings suggest that BSE administration may protect against hepatic injury by reducing oxidative stress and changing the metabolism in habitual alcohol drinkers with fatty liver.

Oxidative stress is inevitable in poultry production, and it affects the physiological, behavioral and biochemical status of growing chicken which ultimately deteriorates meat quality. Appearance, texture, juiciness, tenderness and odor are responsible for the overall meat quality as they are essential perceptible features, which determine the consumer’s judgment. Overproduction of free radicals including reactive oxygen species (ROS) disturbs the mitochondrial function in living cells. During high-temperature mitochondrial substrate oxidation and electron transport chain (ETC) activity increases. This increased activity results in excessive production of superoxide that oxidizes protein and lipid contents in muscle tissues. By oxidizing protein and lipid, ROS spoils the nutritive quality of chicken meat. High ambient temperature is one of the major contributing factors that enhance oxidative stress. Poultry feed with anti-oxidant supplementation and innovative processing techniques can help the poultry industry to overcome oxidative stress.

In the recent years, there has been a great deal of attention in investigating the disease preventive properties of functional foods. Particularly, impact of the antioxidant property of functional foods in reducing the risk or progression of chronic diseases has gained considerable interest amongst researchers and practitioners. Free radicals such as reactive oxygen species are generated in the body by exposure to a number of physiochemical or pathological mechanisms. It is imperative to preserve a balance between the levels of free radicals and antioxidants for routine physiological function, a disparity of which would accelerate oxidative stress. Increased oxidative stress and associated consequences in metabolic disorders such as obesity, cardiovascular diseases and diabetes has warranted the need for exogenous antioxidant concentrates derived from natural foods to alleviate the adverse effects. This chapter provides an overview on the efficacy of functional foods in reducing free radical-mediated damage in metabolic syndrome.

Milk Fat Globule

Milk contains active molecules with important functional properties as the defensive proteins; among them are the whey protein lactoferrin and proteins of the milk fat globule membrane (MFGM) present in buttermilk. The aim of this study has been to investigate the effect of lactoferrin, whey and buttermilk as modulators of intestinal innate immunity and oxidative stress on intestinal epithelial cells, to evaluate its potential use for the development of functional foods. Innate immune Toll-like receptors (TLR2, TLR4, and TLR9) mRNA expression, lipid peroxidation (MDA+4-HDA) and protein carbonyl levels were analyzed in enterocyte-like Caco-2/TC7 cells treated for 24 hours with different concentrations of lactoferrin, whey or buttermilk. None of the substances analyzed caused oxidative damage; however, whey significantly decreased the levels of lipid peroxidation. Furthermore, both lactoferrin and whey were able to reduce the oxidative stress induced by lipopolysaccharide. Respect to TLR receptors, lactoferrin, whey and buttermilk specifically altered the expression of TLR2, TLR4 and TLR9 receptors, with a strong decrease in TLR4 expression. These results suggest that lactoferrin, whey and buttermilk could be interesting potential ingredients for functional foods as they seem to modulate oxidative stress and inflammatory response induced by TLRs activation.

The growth performance of 24 weanling giant rats was studied in 2 experiments of 30 weeks duration with commercial livestock rations and graded levels of protein. Daily average liveweight gain was 5·1-7·3 g, food consumption 26·9-36·3 g on 6 diets. Food intake, growth rate and food efficiency ratio were very similar using the different commercial diets. Growth performance improved as the dietary protein level was raised from 10 to 13%, but a further increase to 16% did not result in greater growth. The commercial pig ration and the experimental diet containing 13% dietary protein level were found to give satisfactory growth, and are recommended for studies with these animals.

Oxidative stress (OS), triggered by overproduction of reactive oxygen and nitrogen species, is the main mechanism responsible for several human diseases. The available one-target drugs often face such illnesses, by softening symptoms without eradicating the cause. Differently, natural polyphenols from fruits and vegetables possess multi-target abilities for counteracting OS, thus representing promising therapeutic alternatives and adjuvants. Although in several in vitro experiments, ellagitannins (ETs), ellagic acid (EA), and its metabolites urolithins (UROs) have shown similar great potential for the treatment of OS-mediated human diseases, only UROs have demonstrated in vivo the ability to reach tissues to a greater extent, thus appearing as the main molecules responsible for beneficial activities. Unfortunately, UROs production depends on individual metabotypes, and the consequent extreme variability limits their potentiality as novel therapeutics, as well as dietary assumption of EA, EA-enriched functional foods, and food supplements. This review focuses on the pathophysiology of OS; on EA and UROs chemical features and on the mechanisms of their antioxidant activity. A discussion on the clinical applicability of the debated UROs in place of EA and on the effectiveness of EA-enriched products is also included.

Antioxidant Effects

Herbal tea with antioxidant ingredients has gained increasing attention in the field of functional foods due to their amelioration potential in aging-related diseases. Wanglaoji herbal tea (WHT) is a kind of traditional beverage made from herbal materials. This study was performed to investigate its antioxidant activity and identify its protective effect on a H2O2-induced cell damage model. In this study, we identified six kinds of phenolic acids with antioxidant activity in WHT, among which rosmarinic acid had the highest content and the highest contribution ratio to the antioxidant activity of WHT. Moreover, compared with the H2O2-induced damage group, the WHT treatment group can significantly increase the viability of cells and decrease the ratio of senescence-associated β-galactosidase-positive cells, intracellular malondialdehyde levels, and the percentage of G1 phase. Furthermore, enrichment analysis of differentially expressed genes revealed that heme oxygenase1 (HMOX1) was a key gene for protective effect of WHT on oxidative stress-induced cell damage. Thus, WHT exerted protective effects not only by scavenging reactive oxygen species but also by inducing the expression of cytoprotective genes by activating the HMOX1 pathway, which showed that WHT had a potential of promoting health by reducing oxidative stress-induced cell damage.
