The goal of this pilot study is to examine the feasibility and effects of an 18-month intervention diet compared to an active control diet (standard diet) in those living with Parkinson's Disease (PD), without dementia. Research has shown that eating components of Mediterranean diets are associated with a 30% lower risk to develop PD and a 40% lower mortality rate in those living with PD. Diet may influence the gut and microbiomes, thus may affect PD risk and progression. This study will examine how easy it will be to adhere to a certain type of diet for 18 months and what changes may occur in the gut microbiome and in PD symptoms on a specific diet during that time. The study will involve in-person study visits at UBC as well as online diet coaching sessions and online group cooking classes over Zoom. This is a randomized study, meaning that participants will be assigned by chance to either the Mediterranean-style diet group or the standard diet group for the duration of the 18 months. This pilot study will also examine recruitment rates and retention, in order to prepare for a larger future study.
The goal of this trial is to examine the effects of a single high-fat meal with or without the co-ingestion of dietary nitrate on exercise-mediated sympatholysis. The main questions it aims to answer are: 1. What are the mechanisms responsible for reduced exercise-mediated sympatholysis following a high-fat meal 2. Can dietary nitrate prevent the declines in exercise-mediated sympatholysis Participants will be asked to complete three study visits in a randomized order: 1. Low-fat meal 2. High-fat meal 3. High-fat meal plus dietary nitrate Exercise-mediated sympatholysis will be measured using Doppler ultrasound via a protocol involving rhythmic handgrip exercise and a lower body negative pressure stimulus. Sympatholysis will be assessed before each meal, and at 1, 2, and 3 hours post-prandial.
Positive effects of herbal supplements such as red berries, ginseng, ashwagandha on athletic performance have been reported. The aim of this study was to evaluate the acute effects of a herbal dietary supplement prepared from a mixture of red berries, ginseng and ashwagandha on aerobic performance of recreational athletes.
The goal of this study is to determine the appropriate target of medically tailored meals (a particular individual vs. the entire household) and means of delivery (a dedicated delivery driver vs. a commercial shipper), to inform subsequent medically tailored meal trials.
Intact whole grains (such as quinoa, buckwheat, and barley) contain all 3 parts of the kernel (bran, germ, and endosperm) compared to processed grains where the bran and germ layers have been removed. Intact whole grains have a higher nutritional value but are under consumed in the diet of most adults. In this proposed pilot study, 42 participants will be recruited to study the impact of convenience on intake of intact whole grains by comparing consumption of intact whole grains that are offered in a convenient pre-cooked ready-to-eat form compared to traditional bulk dried form that requires a more prolonged preparation and cooking time. The ready-to-eat meals will be processed using WSU microwave technologies to ensure food safety. All intact whole grains (ready-to-eat or dried) will be provided to participants, who will prepare and consume the grains at home over a period of 4 weeks. Type and volume of whole grain consumed will be monitored daily via REDCap survey, which will allow the investigators to see if adults are more likely to meet daily recommended intakes of whole grain servings when offered in a convenient form.
The objective of this clinical trial is to verify whether the beneficial effects of weight loss on visceral fat measured by computed tomography and metabolic risk factors for coronary heart disease are maintained once high-risk patients without symptoms and with visceral obesity and dyslipidemia are stabilized and maintained for two additional years after a one-year weight loss (5-10%) program. Before entering the study, after the one-year intervention program, and after the 2-year maintenance period, participants will be asked to take part in multiple assessments: fasting lipid profile and apolipoproteins measurements, oral glucose tolerance test, anthropometric measurements, computed tomography, dual-energy X-ray absorptiometry, oral lipid tolerance test, measurements of inflammatory markers, physical activity and dietary diaries, cardiorespiratory fitness assessed by a submaximal treadmill test, and measurements of resting and exercise blood pressure. During the one-year intervention, participants will be closely monitored by the study's dietitians and kinesiologists to achieve the target weight loss. Dieticians will not recommend a daily energy deficit greater than 500 calories and will focus on foods rather than the nutrient composition of the diet. Participants will have access to the dieticians at all time, and appointments every two months will be required during the first year. Regarding physical activity, kinesiologists will supervise the exercise prescription which will aim at 160 minutes per week of moderate-intensity aerobic-exercise. The physical activity prescription will be adjusted by the kinesiologist according to the participant's preferences and habits. The investigators hypothesize that there will be a worsening in some features of the metabolic syndrome over the two-year weight maintenance period. However, it is suggested the greater the weight loss during the intervention, the less marked the deterioration will be. Finally, the investigators put forward that even in the absence of weight loss during the intervention, the lifestyle modification program will prevent visceral fat accumulation expected to be observed over the two-year maintenance period in the control group maintaining their usual behaviour.
The role of diet in determining glucose intolerance and its progression towards T2DM has been extensively investigated. A 2017 meta-analysis showed that a vegetarian diet is inversely associated with the risk of developing diabetes. Vegetarians, with the same baseline risk, are half as likely to develop T2DM than those following an omnivorous diet. Therefore, vegetarian nutrition could have important clinical implications in the dietary management of diabetic patients.
The aim of the present study is to determine the effects of different standardized dietary patterns on general health markers, intestinal function, immune response and affective processes/ cognitive skills in healthy subjects.
Novel barley varieties high in the soluble fiber β-glucan have the capacity to improve population health through improving glycemic control. Sweetened and unsweetened wholegrain barley foods were tested in a randomized, controlled, crossover human clinical trial to assess impact on postprandial appetite and food intake.
