Description
Fruit and vegetable (FV) consumption continues to lag far behind US Department of Agriculture (USDA) recommendations. Interventions targeting individuals' dietary behaviors address only a small fraction of dietary influences. Changing the food environment by increasing availability of and excitement for FV through local food production has shown promise as a method for enhancing intake. However, the extent to which local production is sufficient to meet recommended FV intakes, or actual intakes, of specific populations remains largely unconsidered. This study was the first of its kind to evaluate the capacity to support FV intake of Arizona's population with statewide production of FV. We created a model to evaluate what percentage of Dietary Guidelines for Americans (DGA) recommendations, as well as actual consumption, state-level FV production could meet in a given year. Intake and production figures were amended to include estimates of only fresh, non-tropical FV. Production was then estimated by month and season to illustrate fluctuations in availability of FV. Based on our algorithm, Arizona production met 184.5% of aggregate fresh vegetable recommendations, as well as 351.9% of estimated intakes of Arizonans, but met only 29.7% of recommended and 47.8% of estimated intake of fresh, non-tropical fruit. Much of the excess vegetable production can be attributed to the dark-green vegetable sub-group category, which could meet 3204.6% and 3160% of Arizonans' aggregated recommendations and estimated intakes, respectively. Only minimal seasonal variations in the total fruit and total vegetable categories were found, but production of the five vegetable sub-groups varied between the warm and cool seasons by 19-98%. For example, in the starchy vegetable group, cool season (October to March) production met only 3.6% of recommendations, but warm season (April to November) production supplied 196.5% of recommendations. Results indicate that Arizona agricultural production has the capacity to meet a large proportion of the population's FV needs throughout much of the year, while at the same time remaining a major producer of dark-green vegetables for out-of-state markets.

Description
Background: Hispanic women are at high risk for Type 2 Diabetes (T2D), in part due to their high prevalence of obesity, which may influence the development of insulin resistance and disease onset. Unhealthy eating contributes to T2D risk. Dietary patterns are the combination of total foods and beverages among individual’s over time, but there is limited information regarding its role on T2D risk factors among Hispanic women. Objective: To identify a posteriori dietary patterns and their associations with diabetes risk factors (age, BMI, abdominal obesity, elevated fasting blood glucose, and hemoglobin A1c) among overweight/obese Hispanic women. Design: Cross-sectional dietary data were collected among 191 women with or at risk for T2D using the Southwestern Food Frequency Questionnaire capturing the prior three months of intake. Dietary patterns were derived using exploratory factor analysis. Regression scores were used to explore associations between dietary patterns and diabetes risk factors. Results: The patterns derived were: 1) “sugar and fat-laden”, with high loads of sweets, drinks, pastries, and fats; 2) “plant foods and fish”, with high loads of vegetables, fruits, fish, and beans; 3) “soups and starchy dishes”, with high loads of soups, starchy foods, and mixed dishes; 4) “meats and snacks”, with high loads of red meat, salty snacks, and condiments; 5) “beans and grains”, with high loads of beans and seeds, whole-wheat and refined grain foods, fish, and alcohol; and 6) “eggs and dairy”, with high loads of eggs, dairy, and fats. The “sugar and fat-laden” and “meats and snacks” patterns were negatively associated with age (r= -0.230, p= 0.001 and r= -0.298, p<0.001, respectively). Scores for “plant foods and fish” were associated with fasting blood glucose (r= 0.152, p= 0.037). There were no other statistically significant relationships between the dietary patterns and risk factors for T2D. Conclusions: A variety of patterns with healthy and unhealthy traits among Hispanic women were observed. Being younger may play an important role in adhering to a dietary pattern rich in sugary and high-fat foods and highlights the importance of assessing dietary patterns among young women to early identify dietary traits detrimental for their health.

Description
A plant based diet may seem intimidating and unwholesome, as it restricts major food groups, such as meat, dairy, and eggs from a diet. The foods restricted are, undeniably, major sources of protein in a diet. However, focusing mainly on four categories, fruits, vegetables, legumes, and grains, I have tested out plenty of recipes to create a cook book that is comprised of nutritious, protein filled, plant based recipes. The cook book is attached to a well-researched "guide book" for new vegans. The guide book contains answers to many asked questions, tips, and tricks to follow a plant based diet with ease. I have written a supplemental paper that includes and explains my blood work from before and after my plant based diet that ties together, and proves, that most nutrients, namely excluding vitamin B12, can be found through a proper and balanced plant based diet. A proper plant based diet can help regulate irregular balances and deficiencies, as I found through my own blood work. Through the research of different texts and scientific journals, I am able to conclude that a proper plant based diet can provide the same, if not more, nutrients that an animal based diet can, as well as provide a sustainable way of living. With an increase in the worlds population, planet Earth must be able to provide a home and food for 2 billion more people. A vegan diet is sustainable for the environment, in comparison to an animal diet, as it cuts down exponentially on the space, water, and food necessary to sustain animal meat.

Description
Objectives. To determine the association between parental level of acculturation using the Anglo Orientation Subscale (AOS) and the Mexican Orientation Subscale (MOS) derived from the Acculturating Rating Scale for Mexican Americans-II (ARSMA II) and their likelihood of serving green salad, vegetables, fruit, 100% fruit juice, and sugar-sweetened beverages during family meals. Methods. A sample of Hispanic parents of 6th, 7th, or 8th-grade adolescents (n=447; 39.8±6.8 years; 89.7% female) enrolled in a parenting intervention promoting healthy nutrition and substance use prevention. Parents completed baseline surveys to self-report whether they had family meals or not, acculturation-related questions, and the frequency with which they serve green salad, vegetables, fruit, 100% fruit juice, and sugar-sweetened beverages (SSB) during family meals. Associations between parental acculturation level and their likelihood of serving green salad, vegetables, fruit, 100% fruit juice and sugar-sweetened beverages during meal times were assessed with Spearman’s rank correlations. Results. There was a positive correlation between a higher level of acculturation on the Mexican Orientation Subscale (MOS) scale and the frequency of serving SSB during family meals (p=.006). There was a positive correlation between a higher level of acculturation on the Anglo Orientation Subscale (AOS) with the frequency of parents serving green salad (p=<.001), vegetables (p=<.001), and 100% fruit juice (p=.025) during family meals. Conclusion. Findings suggest that a higher Mexican orientation is associated with serving more sugar-sweetened beverages, and a higher Anglo orientation is associated with serving more green salad, vegetables, and 100% fruit juice to adolescents during family meals. Further research is needed to understand how the association of parental acculturation, home food environment, family meals, and socioeconomic status impact what they serve during family meals to their adolescents. A better understanding of what is served would help develop more evidence-based interventions that could help improve adolescents’ diet, which could help curb down obesity prevalence.
