Nutrition for obese patients

Abstract

This invention provides a composition and method for providing nutritional support to obese patients. The composition has an energy density between 0.4 and 0.9 kcal/ml and comprises a protein source which comprises at least 30% by weight whey protein and provides at least 30% of the total calories of the composition. The composition may include a carbohydrate source and a lipid source. Preferably, at least 50% by weight of the protein source is whey protein. The invention further extends to use of the composition in the prevention or treatment of malnutrition in obese patients.

1 . Use of a protein source, Vitamin A, Vitamin C, Vitamin E, zinc and selenium in the manufacture of a composition for the prevention or treatment of malnutrition in an obese patient wherein the composition has an energy density between 0.4 and 0.9 kcal/ml and comprises per litre at least 500 μg RE of Vitamin A, 70 mg of Vitamin C, 9.0 mg α TE of Vitamin E, 4.0 mg zinc and 30 mg selenium and the protein source comprises at least 30% by weight whey protein and provides at least 30% of the total calories of the composition. 
   
   
       2 . Use of a protein source, a carbohydrate source and a lipid source in the manufacture of a composition for the prevention or treatment of malnutrition in an obese patient wherein the composition has an energy density between 0.4 and 0.9 kcal/ml and the protein source provides comprises at least 30% by weight whey protein and at least 30% of the total calories of the composition. 
   
   
       3 . The use of  claim 1  or  2  wherein the composition comprises per litre at least 1000 μg RE of Vitamin A, 125 mg of Vitamin C, 15.0 mg α TE of Vitamin E, 10.0 mg zinc and 100 mg selenium. 
   
   
       4 . The use of any preceding claim wherein at least 50% by weight of the protein source is whey protein. 
   
   
       5 . The use of any preceding claim, wherein whey protein constitutes between 60 and 85% by weight of the protein source. 
   
   
       6 . The use of any preceding claim, wherein the protein source provides from 40 to 50% of the total calories of the composition. 
   
   
       7 . The use of any preceding claim, wherein the composition further comprises from 10 to 40 g/l of dietary fibre. 
   
   
       8 . The use of any of  claims 2  to  7 , wherein the carbohydrate source provides from 25 to 45% of the total calories of the composition. 
   
   
       9 . The use of any of  claims 2  to  8 , wherein the lipid source provides from 25 to 30% of the total calories of the composition. 
   
   
       10 . The use of any of  claims 2  to  9 , wherein the ratio of n6:n3 long chain polyunsaturated fatty acids in the lipid source is between 6:1 and 2:1. 
   
   
       11 . A nutritional composition for the prevention or treatment of malnutrition in an obese patient which composition has an energy density between 0.4 and 0.9 kcal/ml and comprises at least 500 μg RE of Vitamin A, 70 mg of Vitamin C, 9.0 mg α TE of Vitamin E, 4.0 mg zinc and 30 mg selenium and a protein source which provides at least 30% of the total calories of the composition, wherein at least 30% by weight of the protein source is whey protein. 
   
   
       12 . A nutritional composition for the prevention or treatment of malnutrition in an obese patient which composition has an energy density between 0.4 and 0.9 kcal/ml and comprises a protein source which provides at least 30% of the total calories of the composition, a carbohydrate source and a lipid source wherein at least 30% by weight of the protein source is whey protein. 
   
   
       13 . The composition of  claim 11  or  12  wherein at least 50% by weight of the protein source is whey protein. 
   
   
       14 . The composition of any of  claims 11  to  13 , wherein whey protein constitutes between 60 and 85% by weight of the protein source. 
   
   
       15 . The composition of any of  claims 11  to  14 , wherein the protein source provides from 40 to 50% of the total calories of the composition. 
   
   
       16 . The composition of any of  claims 11  to  15  wherein the composition further comprises from 10 to 40 g/l of dietary fibre 
   
   
       17 . The composition of any of  claims 12  to  16 , wherein the carbohydrate source provides from 25 to 45% of the total calories of the composition. 
   
   
       18 . The composition of any of  claims 12  to  17 , wherein the lipid source provides from 25 to 30% of the total calories of the composition. 
   
   
       19 . The composition of any of  claims 12  to  18 , wherein the ratio of n6:n3 long chain polyunsaturated fatty acids in the lipid source is between 6:1 and 2:1. 
   
   
       20 . The composition of any of  claims 11  to  19 , wherein the composition further comprises per litre at least 1000 μg RE of Vitamin A, at least 125 mg of Vitamin C, at least 15.0 mg α TE of Vitamin E, at least 10.0 mg zinc and at least 100 mg selenium.
