I can’t believe I haven’t written a post since August! I was naive to believe that I would have time to keep up with things like blogging with a newborn. Even as I type this I’m nursing her and it will probably take me a couple of days to finish writing this post. I’m not complaining, it’s just that my priorities have changed and feeding this little nugget takes up most of my time. However, feeding her has also prompted me to write this post. She has a suspected cow’s milk allergy (suspected because they won’t do allergy testing on infants) and by the comments I’ve gotten from people it seems that there’s a lot of misunderstanding about this allergy.
Food allergies in general are reactions to proteins found in foods. In the case of a cow’s milk allergy, that reaction is to either the whey and/or casein protein found in milk. Babies with a cow’s milk allergy will react to the protein passed to them through breastmilk as well as to the protein in most infant formulas. This means that breastfeeding moms must remove dairy from their diets. For some moms this may just mean obvious sources of dairy such as milk, cheese, and yoghurt (note: eggs are not dairy – I actually read an article by a doctor listing eggs as dairy *face-palm*). More sensitive babies may require complete removal of all dairy-containing foods from their diets, even foods in which a milk product is a very minor ingredient. Babies who are formula-fed will require special hypoallergenic formula in which the proteins are broken-down so that they can digest them.
A cow’s milk allergy is not the same as lactose intolerance which is a reaction to the lactose which is a milk sugar, not a protein. Lactose intolerance is actually extremely uncommon in infants as lactose is present in breastmilk. Generally, lactose intolerance is something that develops as children age. This means that lactose-free dairy products are unsafe for people with cow’s milk allergy and mom’s who are breastfeeding babies with this allergy.
Some people with cow’s milk allergy may tolerate goat’s milk. Goat’s milk contains casein but a slightly different version than that found in cow’s milk. However, the similar structure means that some people who are allergic to cow’s milk will also react to goat’s milk.
In things that I never thought would be an issue: I can’t tell you how many times I’ve asked if a baked good is dairy-free and received the response that they contain gluten. Huh? I’m not sure if this is indicative of people genuinely not knowing what dairy and/or gluten is or if it’s a result of avoidance of both these things being trendy. For those who genuinely may not be aware: dairy is products made from cow’s milk such as ice cream, cheese, yoghurt, milk, and butter. Gluten is a protein found in some grains, wheat being the most commonly consumed.
Do you have a food allergy? I’d love to hear your stories of ignorant comments below.
