Filter by:Increasing attention has been paid to meals with unusual characteristics that are consumed on a semi-regular basis (e.g., "tailgating," pizza buffets). The purpose of this study is to describe the acute cardiometabolic effects of a cinema-style meal rich in refined sugar, total carbohydrate, and moderate in fat (i.e., soda, popcorn, candy).
The goal of this study is to investigate the relationship between vitamin D status and a diabetes risk factor, postprandial glycaemic response in White, South Asian and Black African Caribbean populations in East London. The main question[s] it aims to answer are: - Are there differences in postprandial glycaemic response to a sugar water drink or orange juice between White, South Asian and Black African Caribbean people in East London? - Is there a relationship plasma 25(OH)D and the postprandial glycaemic response to a sugar water drink or orange juice consumption? - What are the knowledge and perceptions of vitamin D intake between White, South Asian and Black African Caribbean people in East London? - Is there a difference in dietary vitamin D intake between the three ethnic groups? Participants will make two visits to the lab, approximately 2.5 hours each. The order of the two drinks will be randomized via Excel Random function. For each visit, the blood sugar levels will be measured at fasting (0) and every 30 minutes up to 2 hours postprandially (5 times total) using a finger prick. At baseline only (visit 1), participants will fill out a knowledge and perception survey, provide a 4-day estimated food diary, provide a 7 ml blood sample via phlebotomy, and have their height, weight and body fat percentage measured.
There are numerous plant foods that are a source of bioactive compounds, which can induce an anti-inflammatory effect on various pathways of inflammatory processes in the body as it may be useful in decreasing markers of inflammation expressed by COVID-19 infectious disease and conditions such as obesity and its comorbidities. Given the above, Hibiscus sabdariffa hibiscus possesses advantages as a potential adjuvant in the management of COVID-19, as studies on the phytochemical properties of H. sabdariffa show that it has several health benefits, and could be used as a potent material for the therapeutic treatment of various diseases. Due to its high content of bioactive compounds, these can exert antioxidant, anti-inflammatory and anticarcinogenic effects, as well as help control blood glucose levels, prevent cardiovascular disease and obesity. In addition, it is a traditional component of the Mexican diet, of common consumption, easy incorporation in the diet, versatility in preparation and national production. Therefore, to evaluate the bioavailability of bioactive compounds present in a beverage developed from the TECNM/ITESO collaboration, as well as the glycemic and insulinemic response produced by its consumption; besides establishing the effect on some inflammation markers that may be activated as a consequence of the SARS-COV-2 virus infection. This will help to increase knowledge about potential treatment/prevention schemes, avoid the development of severe manifestations of the disease, as well as boost the production and market of a national product.
Results from a large number of studies in humans have shown that diets rich in foods that give lower glucose response bring lower risk of type 2 diabetes. Polyphenols, naturally found in fruits, vegetables and grains, have shown the potential to attenuate post-prandial blood glucose spikes following a carbohydrate-rich meal, through partial inhibition of the main enzymes of carbohydrate digestion and reduction in glucose and fructose transport from the gut after digestion and by enhancing the insulin action after glucose reaches the bloodstream. This study is designed to determine whether polyphenols, as normally and naturally present in food extracts and beverages, added to a carbohydrate-rich meal, can lower blood glucose levels after its consumption, and hence lower its glycaemic index, and if this effect is mediated through effects on insulin and other hormones. The study is designed as an acute, double-blind, randomised, placebo-controlled crossover trial in 24 healthy subjects with normal glycaemic response to white bread. Participants will be asked to consume either white bread with pomegranate juice enriched with extracts from grape seeds and apple peels or white bread with placebo drink. The effects on plasma glucose levels, levels of hormones and other biomarkers involved in postprandial response will be determined over 3 hours after the consumption.
