Definitions

  • This invention relates to a method for facilitating or increasing the absorption, by mammals, of minerals from the general diet.
  • this invention relates to a method which involves the administration of an enteral composition containing Lactobacilli micro-organisms.
  • Calcium is, for example, of vital importance for the formation of bones and teeth, muscle contraction and the synthesis of hormones. Calcium is also an essential secondary messenger in most cell activation phenomena.
  • Minerals of which the diet is the primary source, are assimilated by the body by crossing the intestinal mucosa so as to then pass into the blood stream.
  • the degree of assimilation (or of absorption) of minerals by the body in fact depends both on their solubility in the intestinal medium and on the capacity of the intestinal cells to assimilate them and to transfer them into the blood stream (R. Wasserman et al.. In Mineral Absorption in the Monogastric GI Trac. Advances in Experimental Medicine and Biology, 249, 45-65. Plenum Press, N.Y.. 1989).
  • Rasic et al. have reported that the minerals contained in dairy products are assimilated better when these products are fermented. This effect is attributed to the presence of acids in the fermented dairy products (XP002052238: In Fermented Fresh Milk Product, volume 1 , pi 14- 1 15, 1978). More recently, Yaeshima et al. have also shown an increase in the absorption of calcium in rats from a diet of calcium-fortified whey when a combination of oligosaccharides and Bifido bacteria is consumed (XP002052237: Bulletin of the International Dairy Fermentation. No. 313, 1996).
  • this invention provides a method for increasing absorption of minerals from the diet, the method comprising enterally administering to a mammal a nutritional composition which contains a lactobacilli bacteria.
  • lactobacilli are able to directly facilitate or improve the absorption of minerals. especially calcium, by human intestinal cells. Without wishing to be bound by theory, this is thought to be linked to induction of acidification of the microenvironment around the intestinal cells and the bacteria in contact with the intestinal cells. Both the bacteria and the intestinal cells may participate in the induction of acidification. This localized acidification might thus play an active role in the solubilization of minerals, and therefore in the capacity of the body to assimilate them.
  • this invention provides the use of lactobacilli in the preparation of an enteral nutritional composition for facilitating or improving the abso ⁇ tion of minerals by the mammal.
  • the enteral nutritional composition may be used for the treatment or prophylaxis of mineral deficiencies
  • Figure 1 represents the basal abso ⁇ tion of calcium by Caco-2 intestinal cells in the absence ot lactobacilli;
  • Figure 2 represents the influence of about 6.7xl0 7 cfu/ml of various strains of lactobacilli on the absorption of calcium by Caco-2 intestinal cells:
  • Figure 3 represents the influence of about 3.4xl 0 8 cfu/ml of various strains o ⁇ lactobacilli on the absorption of calcium by Caco-2 intestinal cells.
  • the invention relates to the enteral administration of a nutritional composition which contains lactobacilli to facilitate or improve the absorption of minerals present in a daily diet.
  • lactobacilli examples of minerals are calcium, magnesium, iron and/or zinc.
  • the ingestion o ⁇ lactobacilli increases the bioavailability of the minerals, that is to say makes the minerals, which are often not very soluble in the intestine, more accessible to the intestinal cells.
  • lactobacilli strain Any food-grade, lactobacilli strain which may be used.
  • lactobacilli may be used: Lactobacillus acidophilus, Lactobacillus crispatus, Lactobacillus amylovorous, Lactobacillus gallinarum, Lactobacillus gasseri and Lactobacillus johnsonii; Lactobacillus paracasei: Lactobacillus reuterii; Lactobacillus brevis; Lactobacillus fermentum: Lactobacillus plantarum; Lactobacillus casei especially L. casei subsp. casei and L. casei subsp. rhamnosus: Lactobacillus delbruckii especially L. delbruckii subsp.
  • lactis L. delbruckii subsp. helveticus and L. delbruckii subsp. bulgaricus: and Leuconostoc me s enter o ides especially L. mesenteroides subsp. cremoris, for example (Bergey ' s Manual of Systematic Bacteriology, vol. 2. 1986: Fujisawa et al.. Int. Syst. Bact, 42. 487-491. 1992).
  • the lactobacilli may be capable of adhering to intestinal cells but need not be. However, the lactobacilli are preferably such that at least 50 bacteria, in particular at least 80 bacteria, are capable of adhering in vitro to 100 intestinal cells.
  • a culture of bacteria may be spread on a confluent culture of an immortalized line of epithelial cells of the intestine (EP 0802257).
  • the confluent culture washed, and the number of bacteria adhering to the villosities of the line measured.
  • Probiotic lactobacilli are of particular interest. Some strains are in fact capable of adhering to human intestinal cells, of excluding pathogenic bacteria which are on human intestinal cells, and/or of acting on the human immune system by allowing it to react more strongly to external aggression
  • immunomodulation capacity for example by increasing the phagocytosis capacity of the granulocytes derived from human blood (J. of Dairy Science, 78, 491- 197, 1995: immunomodulation capacity of the La- 1 strain which was deposited by Nestec SA with the treaty of Budapest in the Collection Nationale de Culture de Microorganisme (CNCM), 25 rue dondel Roux. 75724 Paris, 30 June 1992, where it was attributed the deposit number CNCM 1- 1225). This strain is described in EP 0577904
  • probiotic strain Lactobacillus acidophilus CNCM 1- 1225 This strain was recently reclassified among the Lactobacillus johnsonii bacteria, subsequent to the new taxonomy, proposed by Fujisawa et al, which is now authoritative in the field of taxonomy of acidophilic lactobacilli (Int. J. Syst. Bact., 42, 487-791, 1992).
  • Other probiotic bacteria are also available, such as those described in EP0199535 (Gorbach et al.). US5296221 (Mitsuoka et al.), US556785 (Institut Pasteur) or US5591428 (Probi AB), for example.
  • the nutritional compositions preferably comprise a sufficient quantity of live lactobacilli for a facilitated abso ⁇ tion of minerals by the intestinal cells, for example at least 10 6 cfu/ml. in particular 10 7 - l ⁇ " cfu/ml, preferably 10 8 - l ⁇ " cfu/ml ("cfu * ' means "colony forming unit ' ').
  • the nutritional composition may also contain other bacteria as desired; for example other probiotic bacteria.
  • the nutritional composition may also include a suitable protein source; for example an animal or plant protein source.
  • suitable protein sources are milk proteins, soy proteins, rice proteins, wheat proteins, sorghum proteins, and the like.
  • the proteins may be in intact or hydrolyzed form.
  • the nutritional composition may also include a suitable carbohydrate source; for example sucrose, fructose, glucose, maltodextrin. and the like.
  • the nutritional composition may also include a suitable lipid source; for example a suitable animal or plant lipid source.
  • suitable lipid sources include milk fats, sunflower oil, rapeseed oil. olive oil, safflower oil. and the like.
  • the nutritional composition may also be fortified with minerals and vitamins. It is especially preferred to fortify the nutritional composition with calcium.
  • the nutritional compositions may be prepared in the form of food compositions intended for human or animal consumption. Suitable food compositions may be provided in the form of liquids, powders, and solids. The nutritional composition may be fermented to obtain a sufficient quantity o ⁇ lactobacilli. Fermented compositions based on milk are thus particularly suitable.
  • milk applies not only to animal milks but also to what is commonly called a vegetable milk, that is to say an extract of treated or untreated plant materials such as legumes (soya, chick pea. lentil and the like) or -
  • oilseeds (rape, soya, sesame, cotton and the like), which extract contains proteins in solution or in colloidal suspension, which are coagulable by chemical action, by acid fermentation and/or by heat. It has been possible to subject these vegetable milks to heat treatments similar to those for animal milks. It has also been possible to subject them to treatments which are specific to them, such as decolorization. deodorization. and treatments for suppressing undesirable tastes. Finally, the word milk also designates mixtures of animal milks and of plant milks.
  • microencapsulation of the lactobacilli has therapeutic advantages.
  • microencapsulation significantly increases the survival of the lactobacilli and therefore the number of live lactobacilli which arrive in the intestine. Even more importantly, the lactobacilli are gradually released into the intestine, which permits prolonged action of the lactobacilli on the abso ⁇ tion of minerals by the intestinal cells.
  • the lactobacilli are freeze-dried or spray-dried (EP0818529), and they are incorporated into a gel consisting, for example, of a solidified fatty acid, a sodium alginate. polymerized hydroxypropylmethylcellulose or polymerized polyvinylpyrrolidone.
  • a gel consisting, for example, of a solidified fatty acid, a sodium alginate. polymerized hydroxypropylmethylcellulose or polymerized polyvinylpyrrolidone.
  • the nutritional compositions need not contain carbohydrates necessary for active fermentation by lactobacilli in the intestinal medium.
  • the facilitated abso ⁇ tion of minerals is independent of the fermentative activity of the lactobacilli, but rather appears to result from the direct contact between the lactobacilli and the intestinal cells. This is thought to induce acidification of the microenvironment and therefore a better solubilization of the minerals.
  • fibres may be selected from, for example, plant pectins, chito-. fructo-. gentio-, galacto-, isomalto-, manno- or xylo-oligosaccharides or oligosaccharides from soya, for example (Playne et al., Bulletin of the IDF 3 13. Group B42, Annual Session of September 95, Vienna).
  • the preferred pectins are polymers of ⁇ - l,4-D-galacturonic acid having a molecular weight of the order of 10 to 400 kDa, which can be purified from carrots or tomatoes, for example (JP60164432).

  • the preferred xylo-oligosaccharides comprise a saccharide portion consisting of 2 to 9 repeating units of structure [- ⁇ - xyl-(l ⁇ 4)-] (Suntory Co.. Japan), for example.
  • the quantity of fibres in the nutritional composition depends on their capacity to promote the development o ⁇ lactobacilli.
  • the nutritional composition may contain from 1 to 50% of such fibres (by weight relative to the dry matter).
  • the concentration o ⁇ lactobacilli may be at least 10 J
  • CFU o ⁇ lactobacilli per g of fibres preferably 10 to 10 CFU/g of fibres.
  • the nutritional compositions may be in the form of any suitable enterally administered food.

  • the nutritional compositions may also be in a form suitable for people who cannot tolerate dairy products. These nutritional compositions will not contain allergenic milk derivatives. For example, for children who are allergic to milk proteins, the nutritional composition may be formulated to contain hypoallergenic milk derivatives. These milk derivatives may be in accordance with European directive 96/4/EC which states that in a hypoallergenic milk, the allergenic proteins should be immunologically at least 100 times less detectable than in a nonhydrolysed milk (Off. J. Europ. Comm.. NoL49/12. annex point 5. a.
  • the nutritional compositions are particularly suitable for the treatment or prophylaxis of people having mineral deficiencies, or to compensate for physiological deficiencies due to a diet low in minerals, or to satisfy major physiological requirements for minerals in children, pregnant women, women who are breastfeeding and the elderly.
