Conducting Research

Research attributes low fruit and vegetable consumption to problems of access, availability and affordability. We conducted, for the first time, a case study with three families designed and analysed using the sustainable Livelihoods Framework. The benefit of such an approach is that we moved away from identified barriers and towards identifying the capabilities and resources low-income families use to incorporate fruit and vegetables into their diets. Mitigating cost and access, we provided families with a box of fresh fruit and vegetables free of charge for up to 10 weeks and observed and recorded how/if the contents were used. Results identify the importance of social networking, organizational skills, knowledge of health benefits, and social structures. This paper demonstrates an effective methodology for understanding the capabilities of, rather than barriers to, low-income families increasing fruit and vegetable intake. Additionally, we provide a ‘how to’ and ‘lessons from the field’ for researchers interested in conducting research of this nature.

Maternal Characteristics

Abstract Objectives This study examines associations of maternal characteristics with infant feeding of discretionary and health-promoting foods. Methods Mothers in PEAS, a prospective cohort study, reported maternal and child dietary intake, demographics, and eating competence (EC). Maternal diet quality (Healthy Eating Index-2015, HEI) was calculated combining 24-hour diet recalls at 6 weeks, 6, and 12 months postpartum (n = 209). Infant food frequency questionnaires were completed at 6, 9, and 12 months, assessing age of introduction and intake frequency of food groups. T-tests examined bivariate associations of demographics with feeding of discretionary sweets, discretionary savory foods, fruit, and vegetables. Linear regressions examined associations of maternal EC and HEI with infant feeding controlling for demographics. Results Fruit, vegetables, discretionary sweet, and discretionary savory foods were introduced at 5.8 ± 1.7, 5.9 ± 1.7, 8.0 ± 2.0, and 8.8 ± 1.8 months, respectively. Earlier introduction of fruit and vegetables was associated with higher maternal education, white race, and nulliparity; earlier introduction of vegetables was also associated with higher income. Age of introduction of discretionary sweet and savory foods was not associated with maternal demographics, HEI, or EC. At age 12 months, greater infant intake frequency of fruit and vegetables was associated with higher education and income, white race, and breastfeeding, while greater intake frequency of discretionary sweet and savory foods was associated with lower maternal education and minority race. Greater intake frequency of sweets was also associated with multiparity and greater intake frequency of discretionary savory foods was associated with lower income. Maternal HEI was positively associated with infant intake frequency of fruit, vegetables, and discretionary sweet and savory foods. Maternal EC was positively associated with infant intake frequency of fruit and vegetables. Conclusions Demographic differences in infant feeding behaviors indicates these behaviors as critical intervention targets to address disparities in child diet quality. Associations of maternal HEI and EC with infant feeding behaviors suggest potential pathways of maternal influence on infant diet.

Salivary Gland Hypofunction

Abstract Xerostomia and salivary gland hypofunction are prevalent conditions in older people and may adversely influence the intake of certain foods, notably fruit and vegetables. Here, we aimed to investigate whether xerostomia and salivary gland hypofunction were associated with a lower intake of fruit and vegetables. The study included 621 community-dwelling adults, mean age 75⋅2 ± 6⋅4 years, 58⋅9 % female, who had participated in the Copenhagen City Heart Study follow-up, and undergone interviews regarding food intake (preceding month), oral and general health (xerostomia, taste alterations, diseases, medication, alcohol consumption and smoking), clinical oral examination and measurements of unstimulated and chewing-stimulated whole saliva flow rates. The average total energy intake (8⋅4 ± 2⋅7 MJ) and protein energy percentage (14⋅8 ± 3⋅1 %) were slightly below recommendations. The average fruit (234⋅7 ± 201⋅2 g/d) and vegetables (317⋅3 ± 157⋅4 g/d) intakes were within recommendations. Xerostomia and hyposalivation were more prevalent in women than in men (16⋅4 v. 7⋅1 %, P < 0⋅001 and 40⋅7 v. 27⋅5 %, P < 0⋅001). Multiple linear regression analyses revealed that older age (β −0⋅009, se 0⋅003, P = 0⋅005), smoking (β −0⋅212, se 0⋅060, P = 0⋅0005) and wearing complete dentures/being partially or fully edentulous (β −0⋅141, se 0⋅048, P = 0⋅003), but neither xerostomia nor salivary flow rates were associated with an inadequate fruit and vegetable intake, after adjustment for covariates. Older age, smoking, tooth loss and denture-wearing were stronger determinants of low fruit and vegetable intakes than xerostomia and salivary hypofunction supporting the importance of dietary counselling and maintenance of oral health and an adequate masticatory performance.

The effect of melatonin pomegranate tree treatments on fruit quality and bioactive compounds with antioxidant activity at harvest and during storage at 10 °C for 60 days was assayed in two consecutive years, 2019 and 2020. In the first year, trees were treated with 0.1, 0.3 and 0.5 mM of melatonin along the developmental fruit growth cycle, and results showed that bioactive compounds (total phenolics and total and individual anthocyanins) and antioxidant activity at harvest were higher in fruits from melatonin-treated trees than in controls. Other fruit quality parameters, such as firmness, total soluble solids and aril red colour, were also increased as a consequence of melatonin treatment. In fruit from control tress, firmness and acidity levels decreased during storage, while increases occurred on total soluble solids, leading to fruit quality reductions. These changes were delayed, and even maintenance of total acidity was observed, in fruit from melatonin-treated trees with respect to controls, resulting in a fruit shelf-life increase. Moreover, concentration of phenolics and anthocyanins and antioxidant activity were maintained at higher levels in treated than in control fruits during the whole storage period. In general, all the mentioned effects were found at the highest level with the 0.1 mM melatonin dose, and then it was selected for repeating the experiment in the second year and results of the first year were confirmed. Thus, 0.1 mM melatonin treatment could be a useful tool to enhance aril content on bioactive compounds with antioxidant activity and health beneficial effects and to improve quality traits of pomegranate fruit, at harvest and during postharvest storage.
