Filter by:In recent decades, the world prevalence of obesity and type 2 diabetes (DMT2) has increased dramatically, resulting in a global epidemic. One of the aspects more connected to the etiology of these pathologies is undoubtedly the concept of the glycemic index (GI) and glycemic load (CG). It has been shown that, with the same CG, that is of carbohydrates contained in a food, a food with a higher GI tends to raise blood sugar more quickly (and consequently insulin), causing several negative effects on the body. We now have sufficient evidence to show that high GI diets are associated with increased incidence of DMT2, hyperlipoproteinemia, and cardiovascular disease. Although simple carbohydrates, namely sugars, have always been considered the major inducers of hyperglycemia and hyperinsulinemia, in reality also starches, or complex carbohydrates digestible by humans, may lead to an increase in blood sugar levels which is not as rapid but often equally harmful to health, since the GC is generally higher. The reason why a high GI diet is responsible for this increased risk of developing pathologies is not unambiguous. We can identify at least 4 probable mechanisms. 1. Sudden hyperglycemia tends to cause insulin to rise beyond what is necessary, leading subsequently to the risk of hypoglycemia and thus an excessive feeling of hunger. Increased energy intake and obesity. 2. Excess insulin secretion, aggravated by insulin resistance, represents an effort for the pancreas with the risk, over time, to arrive at a deficit of insulin-dependent diabetes type 2 insulin production 3. Hyperinsulinemia is also associated with reduced lipolysis and increased lipogenesis obesity and hyperlipoproteinemia 4. Fat accumulation, especially in the abdominal region, is associated with chronic inflammation and insulin resistance by type 2 diabetes tissues and metabolic syndrome In addition to these reasons, a high GI diet, typically called Western Diet, is also generally deficient in plant foods, rich in antioxidants and photo compounds with anti-inflammatory action, without which the process of chronic organic inflammation is accelerated, even in the absence of real obesity.
This study aims to assess the effect of protein on appetite, food intake and gastric emptying in older adults (≥ 65 years) that are more and less active.
This study investigated the effects of two different doses of Crocus Sativus in glucose beverages on glycemic responses.
This study investigated the effects of three doses of spirulina in glucose beverages on postprandial glycemic responses, arterial blood pressure, and subjective satiety.
This study investigated the effects of cookies containing 2.5 g Spirulina on postprandial glycemic and insulin responses.
The investigators present a diet intervention study, to be conducted as a within-subject design, with all food and beverages provided, to allow ad libitum feeding to assess impact of diet change on appetite response. The diets will vary in fibre content and type. This study will allow assessment of the physiological impact of dietary fibre on markers of appetite control for body weight, measured from plasma gut hormones. The investigators propose to recruit participants with a poor diet quality (low habitual fibre intake) to additionally examine the time-course of adaptation of the gut microbiome (measured in faecal samples), whilst assessing the impact of added fibre on body weight and subjective appetite scores. This approach is to address the impact of dietary fibre in people living with obesity and food inequalities. The investigators will assess physiological bio-markers of appetite control and their contribution to the development of a gut ecosystem that promotes health. A subsequent period of return to a low fibre feeding will allow assessment of durability of response.
Our laboratory is investigating the physiological outcomes and health benefits of the consumption of high-quality carbohydrates. One important aspect of the high-quality carbohydrate characteristics is a slow and sustained digestion and glucose release to the blood. In the proposed study, the investigators will evaluate the consumption of different types of slowly digestible carbohydrates (SDCs) and their beneficial effects including moderation of the glycemic response profile (postprandial glycemic response, PPGR) and stimulation of the gut-brain axis, which controls appetite and food intake. This stimulation will be evaluated in terms of second-meal food intake and the circulatory level of appetite-suppressing gut hormones (such as glucagon-like peptide-1).
This project aims to investigate the impact of acute bout of submaximal exercise under different pre-exercise dietary conditions (fasted state versus high carbohydrate breakfast versus high protein breakfast) on postprandial glycaemic, appetite regulation and energy balance in active healthy women.
