The purpose of this study was to evaluate the impact of a nutrition intervention on food insecurity among low-income households with children. Data were collected from 371 parent–child dyads in a quasi-experimental evaluation study of a 1-year intervention (n = 6 intervention schools receiving Brighter Bites, n = 6 wait-list control schools), and longitudinal follow-up of the intervention group 2 years post-intervention in Houston, Texas. Data were collected at three timepoints: at baseline and 1 year for all participants, and at 2 year follow-up for the intervention group (the wait-list control group received the intervention during that time). At baseline, most parents reported food insecurity (60.6%; 70% intervention group, 53.6% control). Food insecurity decreased significantly from 81.3% to 61.7% [(−0.32, −0.07) p = 0.002] among intervention participants immediately post-intervention. After adjusting for ethnicity, 2 years post-intervention the predicted percentage of participants reporting food insecurity decreased significantly by roughly 35.4% from 76.4% at baseline to 41.0% [(−0.49, −0.22), p < 0.001]. Between-group changes were not significant. The re-sults of this study demonstrated a significant positive impact of Brighter Bites on food security in the short and long-term among low-income households with children, albeit results should be in-terpreted with caution.

Adequate consumption of fruits and vegetables is critical for healthy growth and development. Less is known about fruit and vegetable variety, with variation in operationalization of variety. This review aims to identify currently available evidence operationalizing fruit and vegetable (FV) variety through a scoping review to summarize, compare, and critically evaluate the operationalization of variety. A secondary aim is to examine the implications of measuring FV variety and outcomes including dietary quality/nutrient intake. PubMed, Medline, PsycINFO were searched using the following criteria: (1) human study participants ages 2 years and above; (2) assessment of fruit variety consumption, vegetable variety consumption, or combined fruit and vegetable variety consumption; and (3) peer-reviewed publication available in the English language. Etiologic, intervention, and determinant studies were eligible to be included, and 47 studies met inclusion criteria. Differences in operationalization of variety were found. Findings included associations of FV variety with aspects of nutrient intake, dietary behaviors, lifestyle behaviors, and health outcomes. There were no studies that assessed conventionally grown produce vs. organic produce, and none of the included studies assessed cultivar. Nonstandard classification of fruit and vegetables, differences in fruit and vegetables grown in other countries, and the restriction to studies published in the English language may have excluded studies examining variety published in languages other than English. Operationalization of variety should be reported to allow one to explore comparability across studies, use national or international guidelines for greater comparability, associate variety with nutrient intake, and change variety behaviors via intervention.

Despite community college students experiencing food insecurity there has been a dearth of research conducted on the feasibility of providing a program designed to increase access to fruits and vegetables among community colleges. This study used a mixed methods sequential explanatory design to examine the feasibility of delivering an on-campus food distribution program (FDP) to community college students and to examine the association between FDP and food insecurity and dietary intake. The study also explored the student’s experiences related to barriers and facilitators of program utilization. In phase one, the FDP occurred for eight months and students could attend twice per month, receiving up to 60 pounds of food per visit. Online questionnaires were used to collect students’ food security and dietary intake. Among the 1000 students offered the FDP, 495 students enrolled, with 329 students (66.5%) attending ≥ 1. Average attendance = 3.27 (SD = 3.08) [Range = 1–16] distributions. The FDP did not reduce food insecurity nor improve dietary intake. In phase two, a subsample of students (n = 36) discussed their FDP experiences through focus groups revealing three barriers limiting program utilization: program design and organization, personal schedule and transportation, and program abuse by other attendees. Facilitators to greater program utilization included: the type of food distributed and welcoming environment, along with allowing another designated individual to collect food. To maximize program use, it is suggested that reported barriers be addressed, which might positively influence food insecurity and dietary intake.

The purpose of this communication is to describe the Brighter Bites produce voucher program, and its implementation and utilization across Brighter Bites families in four cities in the U.S., during the COVID-19 pandemic. The voucher program was implemented over nine weeks starting April 2020, with up to four USD 25 store-specific produce coupons sent bi-weekly to the homes of each participating Brighter Bites family (USD 100 total/family). Measures included type of produce purchased, amount of voucher that was used, number of vouchers distributed and redeemed by families, and a post-program participant satisfaction survey. Descriptive statistics, including count, frequency, and percent, were computed, both overall and stratified by city. During this time, Brighter Bites distributed a total of over 43,982 vouchers to 12,482 low-income families, with a redemption rate of 60% (at least one voucher redeemed) across all cities. During times of crisis, non-profit–for-profit partnerships, such as the one between Brighter Bites and the grocery retail industry, are feasible, and successful in providing produce to families in need.

Objective:To examine demographic and dietary correlates of consumption of a variety of fruits and vegetables (FV) among Texas adolescents. Different types of FV are needed for adequate dietary intake of vitamins and phytochemicals for proper development and functioning throughout the lifespan.Design:Cross-sectional analysis from the Texas Surveillance of Physical Activity and Nutrition (Texas SPAN) data comparing consumption of a variety of fruit and vegetables by gender, race/ethnicity, and region (Texas-Mexico border/non-border).Setting:Middle, high schools in TexasParticipants:8th, 11th grade Texas adolescents (n=9,056 representing N=659,288) mean age 14.8 years.Results:Within this sample, mean fruit and vegetable variety scores (0-7) ranged from 2.47-2.65. Boys consumed a significantly greater variety of fruit than girls (m=1.12 compared to 1.04). Adolescents in non-border regions consumed a greater variety of vegetables and FV compared to those in border regions. FV variety was associated with healthier eating in the full sample, particularly in the highest Socioeconomic Status (SES) tertile. Within the highest SES tertile, a one-unit increase in variety of fruit, vegetable, and FV was associated with significant increases (p<0.001) in a healthy eating measure, the SPAN Healthy Eating Index: Fruit variety (β=1.33, SE=.29), Vegetable variety (β=0.90, SE=0.28), and FV Variety (β=.81, SE=0.19).Conclusions:Consumption of a greater variety of FV appears to be associated with a healthier overall diet. Associations of FV variety with healthy eating were most significant in the highest SES tertile. These findings support the need to further examine consuming a variety of FV within healthy eating behavior.
