Abstract: The invention relates to a composition having lipolytic activity that comprises at least polyphenols, especially in the form of flavonoids, in particular flavanones and anthocyanins, and phenolic acids, and caffeine. The invention also relates to a process for obtaining such a composition and the use of the composition for its administration with a view to promoting the burning of fats or promoting the loss of body mass.

Abstract: The invention relates to a dietary composition containing at least polyphenols and cartenoids. It is advantageously obtained from a mixture of vegetal species containing at least red and/or white grapes (Vitis vinfera), blueberries (Vaccinium myrtillus), tomatoes (Solanum lycopersicum), carrots (Daucus carrota), and green tea (Camelia sinensis). The invention also relates to a method for preparing the composition and the use of the composition as a food complement and/or for enriching food products in order to reduce the global cholesterol level, in particular the level of cholesterol related to low density proteins (LDL), and/or the atherogenic index, and/or for increasing the antioxidant capacity of blood plasma and/or for reducing the amount of free radicals in the organism. It is advantageously delivered following a dosage of between 10 to 25 mg, preferably of about 21.5 mg of dietary composition per kilogram of body mass per day.

Abstract: The invention concerns a preparation having the property of fixing fats (so as to eliminate from digestion part of the fats ingested during a meal), based on cladodes of cactaceae of the edible type and at least partly non-available. The invention is characterised in that the cactaceae is in the form of powder particles whereof at least 70 wt. % have a size less than 100 &mgr;m (sieve-controlled particle size distribution). Advantageously, the inventive particles of cactaceae cladodes are in the form of granules coated with an acid-resistant film soluble in the intestine and/or with prolonged release. The invention also concerns a method for obtaining such a preparation.
