Intraluminal Nutrients

Intraluminal nutrients increase gut perception, and this effect depends on the concentration and the type of nutrient. At physiological loads, lipids have a marked effect, but the influence of carbohydrates is much weaker (28). Nutrients modify gut motor activity, but their effects on perception are independent. Indeed, the sensitization induced by lipids seems specifically related to mechano-receptors, because perception of transmucosal electrical stimulation of the gut, which activates gut afferents without relaying on any specific receptor, is not modified by intraluminal lipids (27). Cho-lecystokinin (CCK) has been shown to increase the mechanoreceptive response (29), and hence, it could be involved in these effects. Furthermore, in the presence of intestinal lipids, loxiglumide, a CCK-A receptor antagonist, reduces perception of gastric distension (30).

Good Carb Diet

Good Carb Diet

WHAT IT IS A three-phase plan that has been likened to the low-carbohydrate Atkins program because during the first two weeks, South Beach eliminates most carbs, including bread, pasta, potatoes, fruit and most dairy products. In PHASE 2, healthy carbs, including most fruits, whole grains and dairy products are gradually reintroduced, but processed carbs such as bagels, cookies, cornflakes, regular pasta and rice cakes remain on the list of foods to avoid or eat rarely.
