A Clinical Trial to Investigate the Efficacy of Bragg Apple Cider Vinegar on Blood Glucose Control in a Healthy Adult Population

The goal of this clinical study is to investigate the efficacy of a Bragg Apple Cider Vinegar (ACV) liquid on postprandial glucose (PPG) excursion compared to a placebo following a standardized acute carbohydrate load. The main question it aims to answer is: Is there a difference in the incremental area under the curve (iAUC) (from 0 - 120 mins following administration) for venous blood glucose between Bragg ACV liquid and placebo following an acute carbohydrate load. Participants will \[describe the main tasks participants will be asked to consume 750 mg of Bragg Apple Cider Vinegar (ACV) liquid or water and undergo a blood draw to measure glucose, insulin, and future analysis markers.

Effect of Golden Rice-Piper Crocatum Cookies on Neuropathy Prevention in Diabetes

Diabetes mellitus is a chronic disease that can cause many complications, one of the most common being diabetic neuropathy. This condition occurs due to long-term high blood sugar levels that damage the nerves. Symptoms include tingling, burning, pain, and loss of sensation in the feet. If not prevented, neuropathy can progress to diabetic foot ulcers and even lead to amputation. This study aims to evaluate whether Golden Rice Cookies enriched with Red Betel Leaf (Piper crocatum) can help prevent diabetic neuropathy in patients with diabetes. Golden rice is a type of rice that contains beta-carotene (provitamin A) and high fiber, which help maintain stable blood sugar levels and reduce oxidative stress. Meanwhile, red betel leaf contains flavonoids, polyphenols, and alkaloids with antioxidant, anti-inflammatory, and hypoglycemic properties that may protect nerves from damage. Cookies were chosen as the intervention form because they are practical, easy to consume, and widely accepted by patients. In this study, patients will be divided into two groups: an intervention group receiving golden rice cookies with red betel leaf extract, and a control group receiving golden rice cookies without the extract. Changes in neuropathy symptoms will be assessed using the Neuropathy Symptom Score (NSS) before and after the intervention. The expected outcome of this research is to provide scientific evidence that the combination of golden rice and red betel leaf in the form of cookies can serve as an effective, safe, and acceptable functional food to help prevent diabetic neuropathy. This nutritional intervention may support comprehensive diabetes management and improve patients' quality of life.

Golden Rice Cookies With Piper Crocatum for Blood Glucose Control and Quality of Life in People Living With HIV With Hyperglycemia

The goal of this clinical trial is to learn if Golden Rice Cookies with Piper crocatum can help improve fasting blood sugar and quality of life in people living with HIV who have hyperglycemia (GRC-HIV). It will also learn about the safety and acceptability of this dietary intervention. The main questions it aims to answer are: Does Golden Rice Cookies with Piper crocatum lower fasting blood sugar levels in PLHIV with hyperglycemia? Does Golden Rice Cookies with Piper crocatum improve quality of life in PLHIV with hyperglycemia? Researchers will compare Golden Rice Cookies with Piper crocatum to control cookies (iso-caloric cookies without Golden Rice and Piper crocatum) to see if Golden Rice Cookies are effective. Participants will: Consume either Golden Rice Cookies with Piper crocatum or control cookies every day for 28 days Visit the clinic at baseline and follow-up for checkups, laboratory tests, and questionnaires Record their daily cookie consumption and any symptoms or side effects in a diary

Dairy and Vegan Cheese: Effect on Satiety and Blood Glucose

The project will consist of two studies. One study will explore the satiating properties of dairy cheese and its dairy-free substitute when consumed ad libidum, and another study will investigate their effects on postprandial glycemia. Both studies will involve healthy young adults. The secondary outcomes of these studies will be food sensory characteristics, diet-induced thermogenesis, subjective feeling of fatigue and energy, gastrointestinal comfort level, and food intake. The proposed project results will help to better understand the health properties of the cheese and its dairy-free substitute.

Postprandial Response to Fruit Juice

The goal of this clinical trial is to determine postprandial responses to fruit juices.

Identifying Wearable Biomarkers to Monitor Dietary Intake

Background: Measuring what people eat is a challenge in nutrition research. Traditional methods, like food diaries, rely on self-reporting of individuals, and suffer from poor accuracy and recall bias. Aims: This project aims to identify physiological biomarkers related to food and energy intake, which may be used to develop an objective tool to estimate individuals' food intake in future. Eating behaviours are accompanied by significant physiological changes such as skin temperature, blood oxygen saturation, pulse rate etc. The investigators intend to investigate whether monitoring these physiological changes can help us estimate eating behaviour, such as meal size, eating speed, and duration of meals. Study design: Ten healthy adults will be invited for two study visits at NIHR Imperial Clinical Research Facility. Each visit will last for approximately 2 hr. They will consume a high- and low-calorie meal designed by nutritional researchers in a randomised order. During eating events, the investigators will track their physiological changes via a bedside monitor and wearable sensors. Blood samples will be taken from participants to measure their glycaemic response. Associations between energy load, glycaemic response, and physiological changes will be investigated. Our findings may promote an accelerated development of a wearable tool for dietary assessment in future.

Continuous Glucose Monitoring in Intensive Care Unit

Glucose control in ICU patients is challenging and exerts high burden on the nursing staff. Continuous glucose monitors (CGM) are now approved and widely available in the outpatient setting for patients with diabetes mellitus. However, only minimal evidence on CGM performance, reliability and benefit in achieving desired glucose control in the intensive care setting has been gathered so far. The objective of this study is to assess whether the use of CGM helps to maintain blood glucose levels within the time in range recommended for patients in the intensive care. In addition, accuracy of the sensor will be evaluated and compared to measurements of blood glucose by standardized biochemistry methods.
