500 changes suggests some serious REDESIGN.
The percentage of whites with lactose intolerance is fairly consistent with the percentage of whites today who live in deserts or highland areas not conducive to dairy cattle, or in high latitudes where, again, dairy farming is difficult.
Our nuclear family is 100% lactose intolerant. We know about what happens ~ 1 cup?! Hahahahahahah!!!!! You can blow out the toilet with that!
The lactase pills are necessary.
At the same time some dairy products are effectively lactose free ~ yoghurt, Lactaid, aged cheddar, other aged cheeses at least 9 months old ~ more if possible, and those cooked such that the lactose combines with other sugars.
I haven't been able to drink even half a cup of milk for 43 years ~ not even the amount mixed in whipped mashed potatos ~ without also using a lactase pill or eating yoghurt beforehand.
I do not trust The American Dairy Council when it comes to dairy products ~ they lie through their teeth!
Word to the wise ~ given that triple creem brei is pretty much concentrated milk and milk by products, always eat yoghurt before or with a chunk of that stuff. It goes down easier after the mushrooms grow fruiting bodies on top BTW.
I sometimes make my own yogurt (from cream and half and half so it is low carb). Hard to beat it!
