I am 69 years old and have had a problem with dairy product since I was about 40. I used to eat ice cream by the half gallon and down Strawberry milkshakes weekly, until suddenly I had a reaction (intense cramping and diarrhea) one day after drinking a strawberry milkshake from In-N-Out. Since I had never had that reaction before, I decided to try one about a week later, but closer to home:-) and same reaction. Then I realized all my favorite Ice Cream was affecting me too. I assumed it was Lactose Intolerance developed later in life (use to drink a quart of milk at a time almost every day after school as a kid). I am especially sensitive to butter now too. I love Lobster, but cannot tolerate melted butter. I seem to be OK with Yogurt and small portions of Non-Fat milk (Starbucks Non-fat Latte).
As a result of what I have been researching on Lactose Intolerance, I am wondering if my problem is not more related to milk FAT, rather than lactose(?) I read that non-fat milk contains the same amount of lactose as whole milk, but I can tolerate (some) non-fat milk, but NOT whole milk or cream. My question relates to Whey Protein, which is high in lactose, according to what I have been reading. I have used it to make protein-fortified smoothies for quite a while with no ill effects. I also add low-fat Greek yogurt, and eat it by itself often with no adverse reaction. I have eliminated butter from my diet, and though it is hard to eat an airplane meal without cheese being injected in just about everything (including eggs), I avoid cheese as much as possible.
I am now wondering if there is another allergy I have to milk fat, and not necessarily lactose, and if there is a way to test or such a thing; and, if detected, can it be cured or treated…..OR, do I just keep avoiding butter, cheese, whole milk, cream (and cream-based sauces) for the rest of my life. It is certainly not the end of the world to continue avoiding these things, but it would be great to be able to eat things I used to enjoy. Ay suggestions would be helpful!
