NCT ID: NCT04989478 Completed - Fasting Clinical Trials

Postprandial Metabolism in Healthy Young Subjects

PoMet
Start date: August 16, 2021
Phase: N/A
Study type: Interventional

This study aims to describe the dynamic changes in nutritional biomarkers in the blood during the postprandial period, i.e. the time period from the last meal and into the fasting state. In total 36 healthy, young men and women will be recruited in Bergen, Norway, and after receiving a standardized breakfast meal they will consume only water for the next 24 hours.

NCT ID: NCT03994276 Completed - Postprandial Period Clinical Trials

The Postprandial Effects of Chick-Pea Consumption on Glucose, Insulin, and Gut Hormone Responses (PEA-POD).

Start date: June 25, 2019
Phase: N/A
Study type: Interventional

Pulses have a high fibre content, contribute to lowering fasting blood cholesterol levels and improving glycaemic control, and have shown also considerable promise in supporting the dietary management of cardiovascular disease (CVD), type-2 diabetes mellitus (T2DM) and obesity. It is now established that cellular integrity (maintenance of cell wall structure) is a key factor responsible for the low glycaemic index (GI) of pulses. The maintenance of the cell wall structure restricts starch digestion and therefore glucose production in the gut. Thus, cell damage results in a loss of such properties and also the potential health benefits to consumers. This knowledge has presented an opportunity to exploit alternative processing techniques for the manufacture of pulse-based ingredients. We have successfully created a dry powder consisting predominantly of intact cells which still retains low digestibility (>60% resistant starch). This chickpea powder (CPP) was found to be stable under long-term storage, has a neutral taste and aroma, and showed promise as a low GI 'flour-substitute'. This study will investigate blood sugar, insulin and gut hormone levels (post-prandial glycaemic, insulinaemic and hormone responses) following the consumption of CPP consumed at breakfast, as a drink and incorporated into a food matrix (bread).

NCT ID: NCT03572296 Completed - Postprandial Period Clinical Trials

Effect of Drinks Containing Fruit Polyphenol Extracts and Fibre on Postprandial Glycaemia. (Glu-MIX)

Start date: June 25, 2018
Phase: N/A
Study type: Interventional

Postprandial glycaemia refers to the transient rise in blood glucose levels that occurs after consuming a meal. Large fluctuations in blood glucose levels, experienced on a frequent basis, may impair the functioning of pancreatic beta cells, and thus elevate the risk of developing type 2 diabetes mellitus (T2DM) and cardiovascular disease. Our group has previously shown that consuming a drink containing fruit polyphenols immediately before a meal, may reduce postprandial glycaemia. Importantly, other fruit components, namely soluble fibres, also impact on carbohydrate digestion by slowing gastric emptying rates. Combining fruit polyphenols and fibre in a drink may, potentially, have additive or synergistic effects on reducing postprandial glycaemia. This study will investigate the effects of drinks containing blackcurrant polyphenol extract combined with pulp (source of fibre), and pulp alone, on postprandial outcomes and cognitive function following a mixed carbohydrate (starch and sucrose) test meal.

NCT ID: NCT03184064 Completed - Postprandial Period Clinical Trials

Acute Effects of Blackcurrant and Citrus Polyphenol Extracts on Postprandial Glycaemia

Glu-FX
Start date: May 30, 2017
Phase: N/A
Study type: Interventional

Large postprandial glucose responses are associated with increased risk of chronic diseases, including diabetes and cardiovascular disease. Our group have previously shown that fruit polyphenol extracts, when consumed immediately before a mixed carbohydrate meal, reduce postprandial glycaemia. The aim of this study is to investigate the effects of a blackcurrant polyphenol extract and citrus polyphenol extract (and their combination), on postprandial glycaemia, insulinaemia and gastrointestinal hormone concentrations following a mixed carbohydrate test meal. It is hypothesised that blackcurrant and citrus extracts alone will inhibit glycaemia compared to placebo, and a combination of the two will have a greater effect.

NCT ID: NCT01618071 Completed - Vasodilation Clinical Trials

Vascular Effects of Triglyceride-rich Lipoproteins

Start date: June 2012
Phase: N/A
Study type: Interventional

Many types of cardiovascular disease begin when the layer of cells lining blood vessels (endothelial cells) start to function abnormally. This causes white blood cells (monocytes) to enter the blood vessel wall and eventually form lesions. Fats from foods we consume are carried in the blood for 3-8 hours after a fatty meal in small particles known as chylomicrons (CM) and chylomicron remnants (CMR). The overall aim of this project is to investigate the idea that n-3 polyunsaturated fatty acids (PUFA) protect against heart disease by modifying the effect of CMR on endothelial cells and monocytes. We hypothesize that n3-PUFA carried in CMR reduce detrimental events which promote blood vessel damage and activate protective mechanisms to improve the function of arteries.
