A sensitivity to A-Lactalbumin will be to all dairy – this is not the same as lactose (lactose is the sugar portion of animal milks, and a-lactalbumin is a protein).nWe would recommend eliminating all dairy from the diet for 4-6 weeks. This will include all milks, butter, cream, ice cream, milk powders in foods, etc.nThere are many excellent dairy alternatives on the market, and these can be found in all major supermarkets.
