Abstract
A milk which is free of β-casein A1 protein in the prevention or treatment of coronary heart disease is disclosed. In addition, a process for the testing of DNA from cells obtained from lactating bovines for the presence of DNA encoding certain β-casein proteins, selecting the bovines on the basis of the testing, and then milking those bovines to produce milk free of β-casein A1 for use in the prevention or treatment of coronary heart disease is disclosed.
Claims29
A method of preventing or treating coronary heart disease in a human which includes the step of at least reducing the intake in that human of β-casein A1.
A method of producing milk suitable for use in the treatment or prevention of coronary heart disease from one or more lactating bovines which milk is substantially free of β-casein A1 but which contains any one or more of β-caseins A2, A3, B, C, D and E, the method including the steps of:
- (i) testing DNA or RNA from cells containing DNA or RNA obtained from one or more lactating bovines for the presence of DNA or RNA encoding β-casein A1;
- (ii) selecting bovines which do not have any DNA or RNA encoding for β-casein A1;
- and
- (iii) milking the selected bovines.
A method of producing milk suitable for use in the treatment or prevention of coronary heart disease from one or more lactating bovines which milk is substantially free of β-caseins A1, B and C but which contains any one or more of β-caseins A2, A3, D and E, the method including the steps of:
- (i) testing DNA or RNA from cells containing DNA or RNA obtained from the one or more lactating bovines for the presence of DNA or RNA encoding any one or more of β-caseins A1, B and C;
- (ii) selecting bovines which do not have any DNA or RNA encoding for any one or more of β-caseins A1, B and C;
- and
- (iii) milking the selected bovines.
A method of producing milk suitable for use in the treatment or prevention of coronary heart disease from one or more lactating bovines which milk is substantially free of β-casein A1 but which contains β-casein A2, the method including the steps of:
- (i) testing DNA or RNA from cells containing DNA or RNA obtained from the one or more lactating bovines for the presence of DNA or RNA encoding β-casein A2;
- (ii) selecting bovines which are homozygous for DNA or RNA encoding for β-casein A2;
- and
- (iii) milking the selected bovines.
A method of producing milk suitable for use in the treatment or prevention of coronary heart disease from one or more lactating bovines which milk is substantially free of β-casein A1 but which contains any one or more of β-caseins A2, A3, D and E, the method including the steps of:
- (i) testing DNA or RNA from cells containing DNA or RNA obtained from the one or more lactating bovines for the presence of DNA or RNA encoding any one or more of β-caseins A2, A3, D and E;
- (ii) selecting bovines which have DNA or RNA encoding only for any one or more of β-caseins A2, A3, D and E;
- and
- (iii) milking the selected bovines.
A method of producing milk suitable for use in the treatment or prevention of coronary heart disease from one or more lactating bovines which milk is substantially free of β-casein A1 but which contains β-casein A2, the method including the steps of:
- (i) testing DNA or RNA from cells containing DNA or RNA obtained from the one or more lactating bovines for the presence of DNA or RNA encoding β-casein A1 and DNA or RNA encoding β-casein A2;
- (ii) separating bovines which are homozygous for DNA or RNA encoding β-casein A2 from bovines which either have DNA or RNA encoding β-casein A1 or which have DNA or RNA encoding both β-casein A1 and β-casein A2;
- and
- (iii) milking the bovines which are homozygous for DNA or RNA encoding β-casein A2.
A method of producing milk suitable for use in the treatment or prevention of coronary heart disease from one or more lactating bovines which milk is substantially free of β-caseins A1, B and C but which contains any one or more of β-caseins A2, A3, D and E, the method including the steps of:
- (i) testing DNA or RNA from cells containing DNA or RNA obtained from the one or more lactating bovines for the presence of DNA or RNA encoding any one or more of β-caseins A1, B and C and DNA or RNA encoding any one or more of β-caseins A2, A3, D and E;
- (ii) separating bovines which have any DNA or RNA encoding any one or more of β-caseins A1, B and C from bovines which have DNA or RNA encoding only for any one or more of β-caseins A2, A3, D and E;
- and
- (iii) milking the bovines which have DNA or RNA encoding only for any one or more of β-caseins A2, A3, D and E.
