Quality Diet

Oxidative stress has been suggested to be affected by the growth and developmental period of animals, hence it may play an important role in the trade-off between growth and self-maintenance. In this study, I analysed the effects of two different diet regimes (high-quality diet, HQD; low-quality diet, LQD) on growth pattern, three components of the serum oxidative status (hydroperoxides, antioxidant capacity, and thiols), and serum corticosterone in nestling Pigeons ( Columba livia Gmelin, 1789). The growth pattern was similar in the first week of life, after which HQD nestlings grew faster than LQD nestlings. Although there were no differences in serum corticosterone or thiol concentrations, serum oxidative damage increased faster over the nestling phase in HQD than LQD chicks. Serum antioxidant capacity remained stable over time in LQD nestlings and increased in HQD nestlings. This study provides evidence that different growth rates (induced in the absence of any physiological stress or prior nutritional deprivation) are accompanied by different serum oxidative statuses.

Whereas some authors have proposed that sexual dimorphism in the immune response is fixed, others pose that it is dynamic and depends on diet. The aim of the present study was to explore the second hypothesis. Immunocompetence differences between females and males can be linked to resource availability. We tested this idea by providing a low or high quality diet to two groups of Gryllodes sigilatus during their developmental period. Then, at the adult phase half of each group was challenged with LPS from Serratia marcescens. The size, phenol oxidase (PO), and lytic activity were compared between groups according to diet, sex, and immune challenge. Results show that diet quality favor size in both sexes. However, the overall immune response did not seem to be significantly different based on diet, but instead on sex. Females showed greater phenol oxidase levels than males, but the opposite was found with lytic activity. Perhaps in G. sigillatus the differences in the pathogens commonly confronted by each sex in the distinct habitat of each could explain the differences on PO and lytic activity.

Health And Well Being

A high-quality diet is one of the foundations of health and well-being. For a long time in human history, diet was chiefly a source of energy and macronutrients meant to still hunger and give the strength for work and activities that were in general much harder than nowadays. Only few persons could afford to emphasize enjoyment. In the assessment of quality, organoleptic properties were major criteria to detect spoilage and oxidative deterioration of food. Today, food hygiene is a quality aspect that is often taken for granted by consumers, despite its lack being at the origin of most food-borne diseases. The discovery of micronutrients entailed fundamental changes of the concept of diet quality. However, non-essential food components with additional health functions were still barely known or not considered important until recently. With the high burden of obesity and its associated diseases on the rise, affluent, industrialized countries have developed an increased interest in these substances, which has led to the development of functional foods to optimize special body functions, reduce disease risk, or even contribute to therapeutic approaches. Indeed, nowadays, high contents of energy, fat, and sugar are factors associated with a lower quality of food, and products with reduced amounts of these components are valued by many consumers. At the same time, enjoyment and convenience are important quality factors, presenting food manufacturers with the dilemma of reconciling low fat content and applicability with good taste and appealing appearance. Functional foods offer an approach to address this challenge. Deeper insights into nutrient-gene interactions may enable personalized nutrition adapted to the special needs of individuals. However, so far, a varied healthy diet remains the best basis for health and well-being.

A high-quality diet during pregnancy may have positive effects on fetal growth and nutritional status at birth, and it may modify the risk of developing chronic diseases later in life. The aim of this study was to evaluate the association between diet quality and newborn nutritional status in a group of pregnant Mexican women. As part of the ongoing Mexican prospective cohort study, OBESO, we studied 226 healthy pregnant women. We adapted the Alternated Healthy Eating Index-2010 for pregnancy (AHEI-10P). The association between maternal diet and newborn nutritional status was investigated by multiple linear regression and logistic regression models. We applied three 24-h recalls during the second half of gestation. As the AHEI-10P score improved by 5 units, the birth weight and length increased (β = 74.8 ± 35.0 g and β = 0.3 ± 0.4 cm, respectively, p < 0.05). Similarly, the risk of low birth weight (LBW) and small for gestational age (SGA) decreased (OR: 0.47, 95%CI: 0.27–0.82 and OR: 0.55, 95%CI: 0.36–0.85, respectively). In women without preeclampsia and/or GDM, the risk of stunting decreased as the diet quality score increased (+5 units) (OR: 0.62, 95%IC: 0.40–0.96). A high-quality diet during pregnancy was associated with a higher newborn size and a reduced risk of LBW and SGA in this group of pregnant Mexican women.

BACKGROUND: High visceral fat storage unbalance secretion inflammatory peptides, however diet plays an important role-protecting metabolism against chronic diseases inherent to this condition. OBJECTIVE: To assess obese diet quality and find association with inflammatory biomarkers. METHODS: aMED, a Food Quality Index, classified the inflammatory power of 26 obese men’s diet (aged: 48.1±5.1; BMI: 31.1±2.45). Pearson correlation coefficient associated diet quality in tertiles (1st as low, 2nd as average and 3 rd as high quality diet) with inflammatory variables (cytokines and waist circumference). RESULTS: The intake of anti-inflammatory food groups was significantly higher among tertiles (3rd >  2nd >  1st; P <  0.001). Adiponectin was lower in the 2nd tertile than in the 1st (P <  0.05). Whole cereal presented a positive correlation with TNF-alpha (p = 0.049), and a negative correlation with IL–15 (p = 0.002). Fish presented a positive correlation with IL–10 (p = 0.024), Resistin (p = 0.039) and PGE–2 (p = 0.001). These findings pointed to pro and anti-inflammatory responses. CONCLUSIONS: The method may need adjustments when used to assess obese food intake, since they don't usually meet the daily-recommended intake. Other lifestyles variables should be considered, which may affect the inflammatory status.

AbstractUrbanization constitutes one of the major transformations of natural habitats, creating new areas characterized by multiple potential wildlife stressors. Birds that live in highly anthropized zones are confronted with physiological and behavioural challenges caused by these stressors. Here, we investigated if several health parameters differed between three subpopulations of tree sparrow nestlings subjected to different levels of anthropogenic pollution, and particularly noise pollution: a quiet rural area, a noisy rural area adjacent to an airport and a heavily urbanized area. We compared body condition, oxidative stress markers and baseline corticosterone levels, expecting urban nestlings to be in overall worse condition as compared to rural (rural and rural airport) birds. In addition, we expected nestlings exposed to aircraft noise to show intermediate stress levels. We found that rural-airport nestlings had the highest levels of antioxidant capacity of plasma and did not differ from rural counterparts in the rest of the parameters. By contrast, urban nestlings were in slightly worse body condition and had lower antioxidant capacity than rural and rural-airport individuals. Our results suggest that aircraft noise does not constitute a significant stressor for nestlings. In contrast, urban conditions constitute a more challenging situation, negatively impacting different physiological systems. Although nestlings seem able to buffer these challenges in the short-term, further research should explore the long-term potential consequences of early exposure to these conditions.

Background: Coffee pulp has a high content of antioxidants capable of modifying the oxidative status in small ruminants. However, high amounts for a prolonged time can reduce fertility. Objective: To determine the effect of two inclusion levels of coffee pulp during estrous synchronization on reproductive variables and oxidative status of primiparous ewes. Methods: Sixty Suffolk x Dorset primiparous ewes were distributed into three treatments in a completely randomized design; T0: (n=20) 1.5 kg balanced diet, Tl: (n=20) 1.5 kg balanced diet and 5% coffee pulp, T2: (n=20) 1.5 kg balanced diet and 10% coffee pulp. Supplementation was given for 16 days before estrus synchronization and until the beginning of the breeding season. A progestogen (CIDR®) was inserted for ll days and a dose of PGF2a was applied two days prior to its withdrawal. Estrus detection started 12 hours after CIDR withdrawal. Blood samples were obtained during the supplementation period to measure oxidative status, antioxidant capacity, glucose and insulin, and up to 9 days after breeding to determine progesterone concentration. Pregnancy diagnosis was performed at 30 and 60 days post-breeding. An analysis of repeated measures of mixed effects and frequency analysis were carried out. Results: Inclusion of coffee pulp for a short period prior to breeding did not affect reproductive parameters, nor progesterone, glucose or insulin concentrations (p>0.05); however, antioxidant capacity increased, while lipid oxidation showed an opposite trend (p<0.05). Conclusion: Inclusion of up to 10% coffee pulp in the diet of ewe lambs for 16 days prior to breeding improves oxidative status without causing adverse effects on pregnancy, estrus or prolificacy.

AbstractObjectiveTo test the hypothesis that maternal psychological profiles relate to children’s quality of diet.DesignCross-sectional study. Mothers provided information on their health-related psychological factors and aspects of their child’s mealtime environment. Children’s diet quality was assessed using an FFQ from which weekly intakes of foods and a diet Z-score were calculated. A high score described children with a better quality diet. Cluster analysis was performed to assess grouping of mothers based on psychological factors. Mealtime characteristics, describing how often children ate while sitting at a table or in front of the television, their frequency of takeaway food consumption, maternal covert control and food security, and children’s quality of diet were examined, according to mothers’ cluster membership.SubjectsMother–child pairs (n 324) in the Southampton Initiative for Health. Children were aged 2–5 years.SettingHampshire, UK.ResultsTwo main clusters were identified. Mothers in cluster 1 had significantly higher scores for all psychological factors than mothers in cluster 2 (all P<0·001). Clusters were termed ‘more resilient’ and ‘less resilient’, respectively. Children of mothers in the less resilient cluster ate meals sitting at a table less often (P=0·03) and watched more television (P=0·01). These children had significantly poorer-quality diets (β=−0·61, 95 % CI −0·82, −0·40, P≤0·001). This association was attenuated, but remained significant after controlling for confounding factors that included maternal education and home/mealtime characteristics (P=0·006).ConclusionsThe study suggests that mothers should be offered psychological support as part of interventions to improve children’s quality of diet.

An adolescent female athlete has a high risk of suffering iron deficiency. Low-quality diets reflect a lack of variety, adequacy, balance, and moderation, but these have not been associated with iron deficiency. This study aimed to analyze the relationship of diet quality with iron deficiency. Methods, the research was conducted at the Student Center for Education and Sports Training Central Java, the Salatiga athletic club, the Semarang State University athletic, and the swimming club. The subjects were 82 female athletes aged 13-21 years who were selected by purposive sampling. The variables of this study were diet quality and iron deficiency. The diet quality measured by assessing food consumption used the Semi-Quantitative Food Frequency Questionnaire and then the diet quality score calculated by Diet Quality Index-International. Iron deficiency measured based on serum ferritin level. The bivariate was analyzed by the Rank Spearman test. Results, as many as 17,1% of subjects suffering iron deficiency and 95,1% of subjects had low diet quality. Diet quality and its component; Variety, adequacy, moderation, and overall balance were associated with serum ferritin (p<0,05). Energy, protein, iron, fiber adequacy also related to serum ferritin, but vitamin C adequacy was not related to this. In conclusion, low-quality diets are associated with iron deficiency in female athletes.

Abstract Background Differing evolutionary interests of males and females may result in sexual conflict, whereby traits or behaviours that are beneficial for male reproductive success (e.g., traits related to male-male competition) are costly for females. Since sexual conflict plays an important role in areas such as speciation, population persistence or evolution of life history traits, understanding what factors modulate the intensity of sexual conflict is important. This study aims to examine juvenile diet quality as one of the underestimated ecological factors that may affect the intensity of sexual conflict via individual conditions. I used food manipulation during the development of the mite Sancassania berlesei to investigate the effects on male reproductive behaviour and competitiveness, male-induced harm to female fitness and female resistance to this harm. Results Males that were exposed to low-quality food started mating later than the control males, and number of their mating attempts were decreased compared to those of control males. Moreover, males from the low-quality diet treatment sired fewer offspring in a competitive situation than males from the control treatment. However, the fitness of females exposed to males reared on a poor diet did not differ from that of females mated with control males. Furthermore, female diet quality did not alter their resistance to male-induced harm. Conclusion Overall, diet quality manipulation affected male reproductive behaviour and mating success. However, I found no evidence that the intensity of sexual conflict in S. berlesei depends on male or female conditions. Investigating a broad range of environmental factors will provide a better understanding of sexual conflict dynamics and its feedback into associated evolutionary mechanisms.
