Treatment methods requiring phyto-ingredients
The invention provides methods for treatment of conditions which require phytosterol therapy without adversely affecting the bioavailability of lipophilic vitamins or lipophilic drugs. The method includes administering a mixture of phytosterol ester(s) (PS-E) and 1,3-diglyceride(s) (DAG) dissolved in an edible oil or fat. The invention also provides a method of improving weight management and a method of treating metabolic conditions that result in overweight. Dietary nutrients, food supplements and food articles containing the mixture are also provided.
1. A method of increasing or maintaining bioavailability of at least one lipophilic vitamin in a patient receiving phytosterol therapy, wherein the bioavailability of said at least one lipophilic vitamin in said patient is reduced as a result of said phytosterol therapy, said method comprising administering to said patient a therapeutically-effective amount of a mixture of (1) phytosterol ester(s) and/or phytostanol ester(s) (PSE) with (2) 1,3-diglyceride(s) (DAG) dissolved or dispersed in an edible fish oil, wherein fatty acid residues of the PS-E and of the DAG correspond to fatty acid residues of fish oil.
2. The method of claim 1 wherein said patient receiving phytosterol therapy suffers from deficiencies in fat-soluble vitamins resulting from said therapy.
3. The method of claim 2 , wherein said deficiencies in fat-soluble vitamins result from at least one of a metabolic disorder, malabsorption of fats, drug-vitamin direct or indirect interactions impaired vitamin absorption.
4. The method of claim 3 , wherein said patient also suffers from a condition selected from the group consisting of cancer, benign prostatic hypertrophy, organ transplant, ulcer, prostatitis, cardiovascular disorder (CVD), coronary heart disease (CHD), atherosclerosis, pulmonary tuberculosis, human immunodeficiency virus (HIV), stress-induced immune suppression, rheumatoid arthritis, patients receiving any treatment resulting in immunosuppression, autoimmune patients, radiation-treated patients, chemotherapy-treated patients, and allergic rhinitis/sinusitis.
5. The method of claim 1 , wherein said patient receiving phytosterol therapy is a patient that suffers from an immune deficiency including human immunodeficiency virus (HIV), stress-induced immune suppression, rheumatoid arthritis, patients receiving any treatment resulting in immunosuppression, autoimmune patients, radiation-treated patients, chemotherapy-treated patients, allergic rhinitis/sinusitis, and organ transplant patients.
6. The method of claim 5 , wherein said immune deficiency, is accompanied by an increase in serum cholesterol levels.
7. The method of claim 1 , wherein said patient receiving phytosterol therapy is a child suffering from a vitamin or essential nutrient deficiency, including β-carotene, vitamin A, and vitamin D deficiencies.
8. The method of claim 1 , wherein said at least one lipophilic vitamin is a carotenoid.
9. The method of claim 8 , wherein said at least one lipophilic vitamin is vitamin A or vitamin D.
10. The method of claim 1 , wherein the fatty acid residues of the PS-E and of the DAG are docosahexaenoic (DHA) and eicosapentaenoic acid (EPA) residues.
11. The method of claim 1 , wherein the phytosterol ester(s) are fatty acid ester(s) of a phytosterol selected from the group consisting of stigmasterol, sitosterol, beta-sitosterol, brassicasterol, campesterol, 5-avenasterol, and isomers and derivatives thereof and said phytostanol ester(s) are fatty acid ester(s) of a phytostanol selected from the group consisting of beta-sitostanol, campestanol, stigmastanol, and isomers and derivatives thereof.
12. The method of claim 1 , wherein a weight ratio between phytosterol and/or phytostanol esters and diacylglycerol(s) and phytosterol and/or phytostanol ester(s) in said mixture is from 15:1 to 1:1.
13. The method of claim 1 , wherein an amount of diacylglycerol(s) in said mixture is at least 1 wt %.
14. The method of claim 1 , wherein an amount of phytosterol and/or phytostanol ester(s) in said mixture is at least 1 wt %.
15. The method of claim 1 . wherein an amount of diacylglycerol(s) in said mixture is from 1 to 99 wt %.
16. The method of claim wherein said mixture consists of 15 wt % DAG of which more than 50% are 1,3-DAG(s) and 25 wt % total PS-E(s) dissolved or dispersed in fish oil.
17. A method of increasing or maintaining bioavailability of at least one lipophilic vitamin in a patient receiving phytosterol therapy, wherein the bioavailability of said at least one lipophilic vitamin in said patient is reduced as a result of said phytosterol therapy, said method comprising administering to said patient a therapeutically-effective amount of a mixture consisting of (1) phytosterol ester(s) and/or phytostanol ester(s) (PS-E) with (2) 1,3-diglyceride(s) (DAG) dissolved or dispersed in fish oil wherein tai acid residues of the PS-E and of the DAG correspond to fatty acid residues of fish oil.
18. The method of claim 17 , wherein the fatty acid residues of the PS-E and of the DAG are docosahexaenoic (DHA) and eicosapentaenoic acid (EPA) residues.
19. The method of claim 1 , wherein said mixture is comprised in a food article.
20. The method of claim 17 , wherein said mixture is comprised in a food article.
