      @@lorirarich1875 Yeah I've heard some people get sick from Lactaid. I have no such reaction to Lactaid personally. But I tend to perfer the taste of almond milk so I don't drink it that often. But if you were to use it in baking god forbid or simply drink a lot of the product, you would get the same effects as putting real dairy milk in your cookies. Making almond milk the obvious preferred choice as a baking milk. Or perhaps some other brand of milk that is 100 percent lactose free. For something like say cooking, soy milk might be a better option due to it not having a defined sweet flavor.

    Other pro-tip I learned in dairy class: whole milk and cream have less lactose than skim milk and low fat milk. I had already noticed that I could actually drink those without getting sick, (as long as I didn't have too much,) but I didn't understand why. It's actually pretty simple: basically, if you remove one component - in this case fat - the percentages of every other component goes up, because you can't have a substance that only adds up to 95%.

      @FlipFlopAdventures Really? We got taught that in my high school biology class. Though the teacher of that class also couldn't figure out why some beans she boiled weren't germinating, so I suppose I should regard everything she taught with skepticism. It looked like it worked in the lab where we compared lactose levels of regular milk, milk with powdered lactase mixed in, milk that had been heated for 24 hours, and milk with powdered lactase that was heated for 24 hours. The regular heated milk still had lactose in it, but not as much as the regular milk, but it's also possible that the test tube we heated it in had previously been used for milk with added lactase and not properly cleaned (the whole class was an absolute train wreck, so I wouldn't be surprised if the teacher failed to notice some kids not washing the lab equipment properly.) I never actually stopped to question the results since the teacher gave us an A on the assignment. My apologies

    I switched to lactose free milk after buying some to try it. I’m not lactose intolerant but I do have slight sensitivity. The BIGGEST reason I’m staying with it is the long shelf life.

    I'm a chemistry student and we did a similar project, using different methods to create lactose free milk. The methods we used were different from yours and gave some interesting results. In method one we used the chemical properties of lactose to remove it from the mixture, by simply adding ethanol and letting the lactose crystallize. This gave some problems after with removing the ethanol but all of the lactose was removed. We also used a very small filter (similar to a HPLC filter) to remove the lactose. This also removed the fats and a very small amount of lactose still got through. In the end the project was fun to do because we were allowed to come up with our own solutions and gave some nice results

      @Maheen drinking lactaid milk is even worse tho. because they just have more lactase enzymes to counter the increase of lactose caused by pasteurization. Raw milk has very little and has enough natural lactase. Lots of lactose intolerant people can't have lactaid milk but do just fine with raw milk. Not to mention the insane amount of real animal probiotics found in raw milk and fat soluble vitamins lost in pasteurization.

    What's weird is that, for a human, it's actually the dominant mode of being to be lactose intolerant. Most mammals stop producing lactase (or the other related enzymes) and therefore lose the ability to digest milk fairly soon after weaning and never regain the ability to process milk.
    It would be more accurate to describe the minority of people descended from Northern Europeans that can drink milk into adulthood as "lactase persistent", rather than the other way around.

      I've actually always wondered if there are fewer "lactase persistent" people around than we think.

Thus they continue to do so as adults, and don't experience enough discomfort to be prompted to discontinue drinking it.

      Why would it be more accurate? They both distinguish those able to drink milk from those who can't. Why should it matter if the more used term is for the majority?
      Also, I think it's better, because "lactose intolerance" is an inability. It's more important for people to know what they can't consume than what they can.

      0.2 Micron is the standard particulate retention rating to produce sterile liquid filtration. Bacteria will not pass through at 0.2 microns (baseball won’t pass through chain-link fence). Custom combination of both membrane and depth filtration media in filter would be required to retain or pass through certain lipids. Pharmaceutical grade sterile 0.2 Micron rated filters require a filtration efficience of 99.9...% to a log reduction of 9.

    The ultrafiltered process has been the best tasting and best cooking thus far. I hope they start making cheeses.
    I found (as baking is a past time) that this ultrafiltered product tastes and bakes/cooks the same as regular milk. My diet has thus become more pleasant and without the lactose drama!

    Edit: ok so we have two kinds in Norway.
    Fist the one where lactase is added.
    The next one: the milk is sent trough a filter m, removing about 40% of the lactose. Then its made the anted fat percentage, then lactase is added to take care of the remaining lactose. This is the one with a much longer shelf life

    I am lactose-intolerant, and I actually quite like the FairLife brand ultra-filtered lactose-free milk. It doesn't have the overly sweet taste of other lactose-free milks that use enzyme treatment, so I definitely prefer it over others.

    Covid made me mildly lactose intolerant, so I tried lactase pills. They made me way more sick than dairy ever did, so I tried lactose-free milk, and I love it! I've never been a big milk drinker but I enjoy the extra sweetness, and it has a much longer shelf life than normal milk (probably from the extra pasteurization).

    Lactose free milk actually has a longer shelf life than ‘normal’ milk.. Don’t know why, but it’s a fact.
    Here in Denmark it’s 5 weeks, but I have even opened a carton of lactose free milk that had gone two weeks over the 5 week recommendation and there was absolutely nothing wrong with it..
