Nutritional intervention composition containing a source of proteinase inhibitor extending post meal satiety
View Patent ↗The invention relates to a nutritional intervention composition in powder form that is taken before a meal and that extends post meal satiety. The compositions of the invention are comprised of at least one protein, C 12-18 fatty acids, preferably oleic acid, all of which stimulate CCK release in the body, and a source of proteinase inhibitor which acts to prevent the deactivation of CCK. The subject compositions preferably additionally contain a source of calcium and are advantageous in that they utilize a source of proteinase inhibitor as opposed to the more costly extracts. The source of proteinase inhibitor is advantageously an extract of potato, soy, or beans containing about 10 weight percent of proteinase inhibitor. The powder compositions are mixed with a suitable liquid, preferably water, prior to ingestion.
1. A nutritional intervention composition in powder form to be taken before a meal to extend post meal satiety comprising:
(a) from about 63 to 74 weight percent of one or more proteins that stimulate cholecystokinin (CCK) release, said proteins being selected from the group consisting of casein, whey protein and soy protein;
(b) from about 18 to 25 weight percent of C 12-18 fatty acids that stimulate CCK release, said fatty acids comprising at least 50 weight percent oleic acid with the remainder being other C 12-18 fatty acids that stimulate CCK release; and
(c) an amount of an extract of potato, soy, or beans containing a proteinase inhibitor to provide from about 0.16 to about 0.63 weight percent of the proteinase inhibitor.
2. The nutritional intervention composition in accordance with claim 1 further including from about 3.7 to 4.5 weight percent of a source of calcium that stimulates CCK release, said source of calcium being selected from the group consisting of calcium lactate, calcium carbonate, calcium citrate, calcium maleate and calcium citrate maleate.
3. The nutritional intervention composition in accordance with claim 1 , wherein said extract of potato, soy or beans contains about 10 weight percent of said proteinase inhibitor.
4. The nutritional intervention composition in accordance with claim 1 , wherein said composition is mixed with a liquid to form a liquid drink prior to ingestion.
5. The nutritional intervention composition in accordance with claim 4 , wherein said liquid is water.
6. The nutritional intervention composition in accordance with claim 1 , further including a flavor component for imparting a characteristic taste thereto comprising water-soluble, natural or artificial extracts selected from the group consisting of apple, banana, cherry, cinnamon, cranberry, grape, honeydew, honey, kiwi, lemon, lime, orange, peach, peppermint, pineapple, raspberry, tangerine, watermelon and wild cherry.
7. The nutritional intervention composition in accordance with claim 1 , further including a colorant component for imparting a characteristic color thereto comprising water soluble, natural or artificial dyes selected from the group consisting of blue, green, orange, red, violet, and yellow dyes; iron oxide dyes; and ultramarine pigments of blue, pink, red, and violet.
8. The nutritional intervention composition in accordance with claim 1 further characterized in that the calorie content thereof is from about 50 to 150 calories.
9. The nutritional intervention composition in accordance with claim 8 , wherein the calorie content thereof is about 80 calories.
