Chutneys are a form of Indian condiment that can be made in many different flavors and paired with various foods. However, the availability of chutneys in the United States is very limited and many people have not tried them before. With this observation in mind, we founded A2Z Chutneys, which is a business that aims to distribute a variety of organic and locally produced chutneys. Through the Founders Lab program, A2Z Chutneys was created and research was conducted to justify the viability of our business. We were able to gather and interpret data from potential customers, which allowed us to identify a target market. Additionally, time was spent identifying and creating a variety of authentic and unique chutneys that have proven to be desired. This report demonstrates and outlines the feasibility of A2Z Chutneys in providing unique and desirable flavors to the population.

This feasibility study explored the use of an evolutionary mismatch narrative in nutritional education intervention aiming to reduce ultra-processed foods in the diets of veterans with type 2 diabetes and improve diabetic outcomes. Ultra-processed foods are foods that are primarily manufactured through industrial processes. These foods are high in calories but low in nutritional content. Diets high in these foods have been linked to increased health risks. One of the major health risks is type 2 diabetes. Type 2 diabetes is a chronic disease that is developed when cells become unable to properly utilize insulin. Over time this may lead to additional health conditions such as nerve damage, cardiovascular disease, and renal disease. Evolutionary mismatch narrative nutritional intervention offers a different approach to nutritional education to help reduce ultra-processed foods in diets. This study was a randomized controlled feasibility study at the Phoenix VA. Eleven participants were enrolled and randomly selected to be given either an evolutionary mismatch narrative education intervention or general nutritional education about ultra-processed foods. 24-hour diet recalls and blood chemistry were collected and analyzed. Blood chemistry provided diabetes related measurements which included glucose, HbA1c, insulin, HOMA-IR, and C-reactive protein. Statistically significant findings in this study included percentage of ultra-processed foods decreasing for both control and experimental groups from week 0 to week 4 (p=0.014), and C-reactive protein levels between the control and experimental groups (p=0.042). However, baseline C-reactive protein concentrations were lower in the experimental group such that normalizing for group differences at baseline revealed no significant difference in C-reactive protein change between interventions (p = 1.000). There were no other statistically significant values regarding diabetes related measurements. The results from this study suggest that nutritional education in general may help decrease ultra-processed food consumption.
In various studies, sumac, a Mediterranean spice and known antioxidant,39,7,66,67 has been shown to have antioxidant properties through its ability to inhibit reactive oxygen species (ROS) such as superoxide.39,7,66,67 Sumac has also been found to reduce TNF-alpha.100 Results from a study of hypertensive human subjects fed a sumac supplement showed a decrease in blood pressure.59
In the current study, COX-2 levels were determined to evaluate the level of inflammation in response to palmitate when primary aortic human vascular smooth muscle cells (HAoVSM) were treated with sumac. The treatments included: vehicle (bovine serum albumin), 100 µM palmitate, and 10, 20, 40, 60, and 80 µg/mL sumac. Sumac did not alter COX-2 protein levels between vehicle and sumac groups. Additional studies were designed to examine whether 80 µg/mL sumac could reverse impaired vasodilation caused by 10 weeks of high fat intake, consisting of 60% of total calories from fat, in Sprague-Dawley rats. Mesenteric arteries were isolated and exposed to sumac. High fat diet (HFD) arteries had impaired vasodilation compared to arteries from chow-fed fats. HFD arteries exposed to sumac had similar endothelium-dependent vasodilation responses as those not exposed to sumac, however, there were trends for improved vasodilation. I suggest that sumac likely exhibits antioxidant capabilities that prevent superoxide from decreasing the bioavailability of nitric oxide in the vasculature, thus promoting endothelium-dependent vasodilation and preventing the creation of more harmful reactive oxygen species. Isolated arteries from chow fed rats developed irreversible vasodilation when exposed to sumac and were therefore not responsive to pre-constriction with phenylephrine (PE) likely related to nitrates and gallic acid naturally present in sumac whereby inhibiting PE.
One Particular nutrient that is commonly lacking in the vegetarian diet is vitamin B12. Vitamin B12 is found mainly in animal-derived food sources such as meat, poultry, fish, dairy, and eggs. Although some vegetarians, called lacto-ovo vegetarians, consume dairy and eggs, vegans do not consume any animal products at all. Vitamin B12 deficiency can have devastating consequences on the human body due to its role as a methylation cofactor. Metabolism, DNA replication, and cancer formation all involve methylation processes.
This cross-sectional, differential study aimed to further understand the relationship between vegetarianism, vitamin B12 status, and methylation capacity in healthy adults. A group of 34 healthy adults (18 vegetarians and 16 omnivores) was recruited to analyze serum B12, homocysteine, methylmalonic acid, serum total folate, and transcobalamin II status. It was hypothesized that (1) vegetarians would have a lower vitamin B12 status, and thus, a lower methylation capacity than omnivores and that (2) low vitamin B12 status would be correlated with low methylation capacity.
The data show that vegetarians did not have significantly lower vitamin B12 methylation capacity status than omnivores. Nor was vitamin B12 status correlated with methylation capacity. However, the data revealed that diet quality had a positive influence on folate status. There was also a statistical trend (p=0.08) for homocysteine reduction in participants consuming high-quality diets. The data herein suggest that methylation capacity may be impacted by the quality of diet rather than the type of diet.
States, rates of this disease continue to rise. Recent findings suggest that antiseptic mouthwash use may increase blood pressure through elimination of oral bacteria that facilitate the enterosalivary nitrate-nitrite-nitric oxide pathway.
Objective. The purpose of this randomized, controlled, crossover trial was to examine the effects of antiseptic mouthwash use and sodium intake on blood pressure and salivary nitrate levels in prehypertensive adults.
Methods. Healthy adults (n=10; 47.3±12.5) with mildly elevated blood pressure (average baseline blood pressure of 114.9/75.2 mmHg) were recruited and were randomly assigned to a control condition, antiseptic mouthwash use, or antiseptic mouthwash use + consumption of three pickles per day (~6000 mg/day of sodium) for a total of 7 days. Given the crossover design of this study, participants adhered to a 1-week washout period between each condition and all participants received all three treatments. Findings were considered significant at a p-value of <0.05 and a repeated measures ANOVA test was used to compare change data of each condition.
Results. Changes in systolic and diastolic blood pressure were not statistically significant (p=0.469 and p=0.859, respectively). Changes in salivary nitrite levels were not statistically significant (p=0.493). Although there appeared to be fluctuations in sodium intake between interventions, differences in sodium intake were not statistically significant when pickles were not accounted for (p=0.057).
Conclusion. Antiseptic mouthwash use did not appear to induce significant changes in systolic or diastolic blood pressure in this population.
Effect of a Wii Fit® intervention on balance, muscular fitness, and bone health in middle-aged women
and kidney disease. However, the impact of short term high fat intake on the etiology of kidney disease has not been well-studied. Therefore, this study examined the impact of a six week HFD (60% fat) on kidney structure and function in young male Sprague-Dawley rats. Previous studies have shown that these animals develop indices of diabetes compared to rats fed a standard rodent chow (5% fat) for six weeks. The hypothesis of this study is that six weeks of HFD will lead to early stages of kidney disease as evidenced by morphological and functional changes in the kidney. Alterations in morphology were determined by measuring structural changes in the kidneys (changes in mass, fatty acid infiltration, and structural damage). Alterations in kidney function were measured by analyzing urinary biomarkers of oxidative RNA/DNA damage, renal tissue lipid peroxidation, urinary markers of impaired kidney function (urinary protein, creatinine, and hydrogen peroxide (H2O2)), markers of inflammation (tumor necrosis factor alpha (TNFα) and interleukin 6 (IL-6)), as well as cystatin C, a plasma biomarker of kidney function. The results of these studies determined that short term HFD intake is not sufficient to induce early stage kidney disease. Beyond increases in renal mass, there were no significant differences between the markers of renal structure and function in the HFD and standard rodent chow-fed rats.
