Description
The aim of this paper is to investigate a few of the primary pillars of the Paleo diet for evidence to either support or refute their efficacy and safety such that a more educated decision can be made by lay-persons who are wishing to make improvements in their overall health via dieting. To accomplish this goal a basic overview of The Paleo Diet (also known to some as the Paleolithic Nutrition Movement) is given based on the writings of Dr. Loren Cordain in his book The Paleo Diet. Next, analyses of a few of the basic characteristics of the diet are presented based on an in-depth literature review that was performed using PubMed (Medline), Cochrane and Google Scholar databases until March of 2015. The findings of this investigation raise concerns with respect to the safety of some of the main principles of the diet such as its high protein, low carbohydrate content that is relies heavily on the consumption of red meat. The current literature on what the diet of the people of the Paleolithic era may have consisted of is also presented in order to shed light on the origins of the diet and see how closely the diet prescribed The Paleo Diet meshes with the most current data on the topic.

Description
Due to persistent undernutrition in India and the increased demands placed on a woman’s body during childbearing and lactation, the Indian government has implemented a program to provide supplemental nutrition packets to women in rural India. This study examines the factors influencing uptake of nutritional packets by lactating mothers in southern, rural Rajasthan. Women were recruited from 65 villages in Rajasthan, India (n=149, minimum of 2 per village) to evaluate the relationship of nutrition packet uptake and two factors--education levels and distance to the health center.
Level of education had little impact on whether or not women received the nutrition packet. Of those women with no education, 63.1% received the packet. Of those with any education, 63.9% got the packet.
In contrast, distance was strongly correlated with whether or not women received the packet. For example, of the women living within 200 meters of the health center, 93.2% received a nutrition packet. Of the women living between 250 meters and one kilometer of the health center, 68.4% received a nutrition packet. Of the women living over one kilometer from the health center, only 25% received a nutrition packet. The relationship between uptake of packets and women’s perception of distance to the health center was also explored. Out of 50 women who did not receive the packet, all of the women who said there was no health center in their village did live more than one kilometer from a health center. Of the women who lived between 250 meters and one kilometer from the health center, 40% felt it was too far. Of the women who lived more than a kilometer from the health center, 66.7% felt it was too far and 29.6% said there was no health center in their village. Again, it does not appear that ‘too far’ is just a default reason for women, but that actual distance, more so than education, is a major contributing factor in their ability to take the nutrition packet. These findings suggest that improving access to supplemental nutrition packets at the village level may increase uptake by the women.

Description
There has long been a link tied between obesity and such pathological conditions as nonalcoholic fatty liver disease and type two diabetes. Studies have shown that feeding rats a diet high in fat results in hepatic steatosis and steatohepatitis. Using a novel short term diet of six weeks with male adolescent Sprague-Dawley rats, our laboratory sought to investigate the early effects of high fat intake on the liver. Prior findings in our laboratory found that a high fat diet (HFD) leads to nonalcoholic fatty liver disease as well as other symptoms of metabolic syndrome. This study hypothesized that rats fed a 60% HFD for 6 weeks, unlike a high sucrose or standard chow diet, would have an elevated expression of pro-inflammatory cytokines associated with steatohepatitis. TNF-α, TLR4 and XBP1 were chosen for their link to hepatic inflammation. The results of this study found that contrary to the hypothesis, the high fat diet did not induce significant changes in the expression of any inflammatory marker in comparison to a high sucrose or control chow diet.

Dogs' health and wellbeing is of great importance to their owners. The most common nutritional problem for pet dogs is obesity, with 22-40% of pet dogs being classified as overweight or obese. With many adverse health effects associated with obesity, this is a major concern for owners and veterinarians. The degree to which dogs enjoy consuming certain foods can have substantial implications for their body weight, so it is important to understand which aspects of foods make them appealing to dogs. This study aimed to determine whether nutritional aspects of commercial dog foods predict dogs' preferences for those foods. It was found that consumption preference is positively correlated with protein content (p < .001), therefore implying that the protein content of commercial dry dog foods may predict dogs' consumption preferences. Consumption preferences were not predicted by other available measures of food content or caloric value. Dogs' preference for foods high in protein content may be due to the satiating effect of protein. Since foods high in protein both reduce the amount of energy consumed and are found to be palatable to dogs, high-protein dog foods may offer a way for dog food manufacturers, veterinarians, and pet owners to combat obesity in pet dogs.

Description
This study was conducted to observe the effects of vitamin C supplementation upon the expression of sICAM-1 in asthmatic subject. Two groups were created, each with a sample size of 4 subjects. One group was the vitamin C group (VC) and the other was the placebo group (PL). The study was analyzed through observing concentrations of biomolecules present within samples of blood plasma and nasal lavages. These included vitamin C, sICAM-1 expression, and histamine. The following P-values calculated from the data collected from this study. The plasma vitamin C screening was p=0.3, and after 18 days of supplementation, p=0.03. For Nasal ICAM p=0.5 at Day 0, p=0.4 at Day 4, and p=0.9 at Day 18. For the Histamine samples p=0.9 at Day 0 and p=0.9 at Day 18. The following P-values calculated from the data collected from both studies. The plasma vitamin C screening was p=0.8, and after 18 days of supplementation, p=0.03. The change of vitamin C at the end of this study and the combined data both had a P-value that was calculated to be lower than 0.05, which meant that this change was significant because it was due to the intervention and not chance. For Nasal ICAM samples p=0.7 at Day 0, p=0.7 at Day 4, and p=1 at Day 18. For the Histamine p=0.7 at Day 0 and p=0.9 at Day 18. This study carries various implications although the study data was unable to show much significance. This was the second study to test this, and as more research is done, and the sample size grows, one will be able to observe whether this really is the mechanism through which vitamin C plays a role in immunological functions.

Banking on a Diet: https://www.youtube.com/watch?v=Jamp5HYDDqg My documentary is about people with diet-related diseases and restrictions who receive food from a food bank. There has historically been very little research on this clientele, but that is changing. In 2014, the hunger research organization Feeding America asked Americans seeking food assistance if they had a diet-related disease. According to Feeding America's Hunger in America report, the survey found that 58 percent of national households have a member with high blood pressure. In Arizona, that's 54 percent. The survey also found that 33 percent of national households have a member with diabetes. In Arizona, that's 42 percent. Dietary restrictions such as food allergies or religious guidelines, on the other hand, are still not reported. I interviewed several food bank clients who, aside from having a diet-related disease, can't eat certain foods because of an allergy, adverse reaction with their medications, or religious guidelines. No matter the individual case, food banks are beginning to realize there's a growing population of clients who can't get the food they need. Food banks nationally, and in Arizona, are taking steps to accommodate the clients they serve who have diet-related diseases and/or dietary restrictions. My documentary focuses on those food bank clients, as well as what the food banks are doing to accommodate them. The biggest issue is that food banks can only work with the food they receive, or use the money that's donated to them to purchase food. The food banks do their best with what they're given and the clients do the same. According to Association of Arizona Food Banks, two of the food bank leaders in diet-conscious services are Desert Mission, a member of AAFB and the HonorHealth system, and Cultural Cup, an independent food bank separate from AAFB. I focused on these two food banks and their clients for my documentary.

Description
This project looks into elementary school lunches around the world, with a focus on nutrition and government involvement. The project uses recent obesity research to determine the extent of childhood obesity and draws connections between obesity rates and each country's school food policies and resulting school lunch meals. The countries researched are Greece, the United States, Japan, and France. An effort is made to find accurate representations by using real unstaged pictures of the school lunches as well as using real, recent school lunch menus. Analysis of the nutritive balance of each country's overall school lunch meals includes explanation of possible reasoning for lower quality or lesser-balanced school lunch meals. In Greece, the steadily rising child obesity rates are possibly due to Greece's struggling economy and the loss of traditional Greek foods in school lunches. In the U.S., the culprit of uncontrolled obesity rates may be a combination of budget and an unhealthful food culture that can't easily adopt wholesome meals and meal preparation methods. However, there have been recent efforts at improving school lunches through reimbursement to schools who comply with the new USDA NSLP meal pattern, and in combination with a general increased interest in making school lunches better, school lunches in the U.S. have been improving. In Japan, where obesity rates are fairly low, the retaining of traditional cuisine and wholesome foods and cooking methods in combination with a higher meal budget are probable reasons why child obesity rates are under control. In France, the combination of a higher budget with school lunches carefully calculated for balance along with traditional foods cooked by skilled chefs results in possibly the most healthful and palatable school lunches of the countries analyzed. Overall it is concluded that major predictors of more healthy and less obese children are higher food budgets, greater use of traditional foods, and more wholesome foods and cooking methods over packaged foods.

There are two goals for this honors student project: (1) to determine (using an online survey) what college students do and do not know about cooking and preparing foods and (2) to video record short demonstrations of several cooking skills that college students lack the most based on survey responses. Ultimately, this project hopes to help students develop skills they can use in the kitchen to encourage more cooking at home and less eating out, dietary changes that should lead to more healthful meals and a healthier population.

Description
The objective of this study was to access whether there were any associations between food insecurity, weight status and emotional eating for adults and youth, and to discover whether emotional eating was prevalent for both age groups. By gathering participants from six various low-income housing communities throughout the Phoenix, Arizona, the researchers were able to gather data from 114 participants, 57 adults and 57 youth. The participants were a convenience sample, and were recruited by flyers sent via the mail and door-to-door announcements in the spring and summer of 2014. The adult and youth were asked to complete a survey that was part of a larger study, which included the Weight-Related Eating Questionnaire to access the participants' emotional eating. The participants' height and weight were measured manually and were integrated into the BMI system, and the participants' food insecurity statuses were validated using the US Household Food Security Survey. The results of the study illustrated associations between food insecurity and emotional eating for adults, but not for youth. In addition, there were no associations between adults' emotional eating and their child's emotional eating. The results from this study were consisted with the current research examining the associations of food insecurity and emotional eating, where there is only a correlation between food insecurity and emotional eating for adults. However, this study was not consistent with past research accessing the associations between adults' emotional eating and their child's emotional eating since this study found no relationship between the two. Being that a cross-sectional survey-based research was incorporated into this study, further research needs to explore on food insecurity, weight status and emotional eating to determine their causality.
