GENDER SPECIFIC SYNTHETIC NUTRITIONAL COMPOSITIONS AND NUTRITIONAL SYSTEMS COMPRISING THEM
Gender specific synthetic nutritional compositions for infants up to 1 month of age, wherein the leucine and/or threonine and/or tyrosine content is adapted based on that found in HM produced for an infant of the same gender and age, and nutritional systems comprising them.
1 . A gender specific synthetic nutritional composition for an infant up to 1 month of age wherein, the concentration of at least one amino acid selected from the group consisting of leucine, threonine, and tyrosine in the composition is adapted based on that found in human milk produced for an infant of the same gender and age.
2 . A gender specific synthetic nutritional composition according to claim 1 wherein, if the concentration of leucine is adapted to a male infant it is 84.9 to 438.5 mg per 100 g and, if the concentration of leucine is adapted to a female infant it is 92.6 to 352.8 mg per 100 g; if the concentration of threonine is adapted to a male infant it is 41.7 to 306.2 mg per 100 g and, if the concentration of threonine is adapted to a female infant it is 43.6 to 229.1 mg per 100 g; if the concentration of tyrosine is adapted to a male infant it is 30.4 to 160.1 mg per 100 g and, if the concentration of tyrosine is adapted to a female infant it is 23.4 to 160.1 mg per 100 g.
3 . A composition according to claim 1 wherein, the gender specific synthetic nutritional composition is selected from the groups consisting of: infant formula; and a composition for infants that is intended to be added to or diluted with human milk.
4 . A method of preparing a nutritional composition comprising: measuring out an appropriate amount of a gender neutral synthetic nutritional composition and mixing it with a diluent and/or additive to produce a gender specific synthetic nutritional composition for an infant up to 1 month of age wherein, the concentration of at least one amino acid selected from the group consisting of leucine, threonine, and tyrosine in the composition is adapted based on that found in human milk produced for an infant of the same gender and age.
5 . A nutritional system comprising a gender specific synthetic nutritional composition comprising a gender specific synthetic nutritional composition for an infant up to 1 month of age wherein, the concentration of at least one amino acid selected from the group consisting of leucine, threonine, and tyrosine in the composition is adapted based on that found in human milk produced for an infant of the same gender and age.
6 . A nutritional system according to claim 5 comprising one gender specific synthetic nutritional composition selected from the group consisting of: if the concentration of leucine is adapted to a male infant it is 84.9 to 438.5 mg per 100 g; if the concentration of leucine is adapted to a female infant it is 92.6 to 352.8 mg per 100 g; if the concentration of threonine is adapted to a male infant it is 41.7 to 306.2 mg per 100 g; if the concentration of threonine is adapted to a female infant it is 43.6 to 229.1 mg per 100 g; if the concentration of tyrosine is adapted to a male infant it is 30.4 to 160.1 mg per 100 g; and if the concentration of tyrosine is adapted to a female infant it is 23.4 to 160.1 mg per 100 g.
7 . A nutritional system according to claim 5 further comprising a gender specific synthetic nutritional compositions for an infant of more than 1 month of age wherein, the concentration of leucine and/or threonine and/or tyrosine in the gender specific synthetic nutritional compositions does not differ by gender for infants of the same age.
8 . A nutritional system according to claim 5 further comprising gender neutral synthetic nutritional compositions for infants of more than 1 month of age.
9 . (canceled)
10 . A method for use to treat, protect or mitigate sub optimal growth and development of an infant comprising administering a gender specific synthetic nutritional composition to an infant up to 1 month of age wherein, the concentration of at least one amino acid selected from the group consisting of leucine, threonine, and tyrosine in the composition is adapted based on that found in human milk produced for an infant of the same gender and age.
11 - 12 . (canceled)
13 . A kit for providing an optimized amount of leucine and/or threonine and/or tyrosine to an infant, the kit comprising:
a gender neutral synthetic nutritional composition; and
a label indicating dosage requirements for a male and/or female infant so as to arrive at a gender specific nutritional composition, the gender specific synthetic nutritional composition is for an infant up to 1 month of age wherein, the concentration of at least one amino acid selected from the group consisting of leucine, threonine, and tyrosine in the composition is adapted based on that found in human milk produced for an infant of the same gender and age.
