One would receive their daily milk bottles from the milkman. Nowadays, the number of milk alternatives is enough to make anyone’s head swirl. There is skim milk, organic milk, fortified milk, raw milk, low-fat milk, buttermilk, A2 milk, lactose-free milk, flavored milk, condensed milk, powdered milk, evaporated milk, scalded milk, and now protein milk. There is a common baseline process that all milk variants go through. First, once the milk is obtained from the cow, which is the raw milk, it has to undergo a pasteurization process at a processing plant. In this step, the milk is heated to 72°C for 15 seconds to kill off any harmful bacteria. During the pasteurization process, you often get milk fat particles. Therefore, the next step is to homogenize the milk so that it has the smooth texture we are all familiar with. This is done by passing the milk through small holes at high pressures to break down the milk fat particles. Once these are broken down, the milk can be cooled down to 4°C. The high temperature used for processing up to this point causes many nutrients of milk such as fat-soluble vitamins A and D and calcium to be lost. Therefore, most countries require dairy industries to put milk products through a fortification process that adds back these essential nutrients. These are typically added back in the form of powdered vitamins and minerals. Once these basic steps are completed, producers can generate several different milk alternatives. Some refer to these as “designer milk” products. The most recent milk variant is a protein milk that has a higher amount of protein than regular milk. This might draw the attention of anyone trying to get more “gains” at the gym. In contrast to protein shakes, high-protein milk, otherwise known as ultra-filtered milk, does not have an increased protein content due to the addition of protein powder. Rather, it is produced through an ultrafiltration process. In the ultrafiltration process, the regular whole milk is passed through various semi-permeable membranes which act as filters that separates milk components based on their molecular weight sizes. This means that the low molecular components of milk such as lactose, minerals, and water can be separated from the high molecular components such as milk proteins. Once all the components are separated, the dairy industry can decide which components to add more or less of. In the context of high-protein milk, they often choose to add more milk proteins. This results in 18 grams of protein per serving of ultra-filtered milk in comparison to the typical 8 grams of protein in regular milk. In addition, this “designer milk” often also contains 50% less sugar and more calcium than regular milk. Furthermore, since the ultra-filtration process removes most of the lactose, brands such as Fairlife have chosen to add lactase enzyme to also make the milk completely lactose-free. We were all told growing up that we needed milk to grow strong, but do we really need high-protein milk? There is no doubt that protein has become a major player in the health and wellness industry. It seems that most companies and influencers are encouraging consumers to increase their protein intake. However, while protein is certainly an important nutrient in our diets, most people consume the recommended 0.8 grams per kilogram of weight in a normal day of eating. People who are worried about protein intake, especially high-performing athletes, typically turn to protein powders and supplements. However, it has been suggested that protein powders may not necessarily be ideal for muscle building due to protein spiking. Furthermore, since protein powder is a dietary supplement, it is up to the manufacturers to determine the safety of the product. Recent studies by the Clean Label Project screened 134 protein powder products and found 130 types of toxins among these products; these toxins included heavy metals such as lead, arsenic, cadmium, and mercury, bisphenol-A(BPA), pesticides, and even PFAS. Since the long-term effects of supplementing with protein powder have yet to be determined, ultra-filtered milk may be an attractive option for individuals with low-protein intake or high-endurance athletes looking to increase their protein intake in a “cleaner” manner. However, most individuals don’t require this extra protein source and would not benefit from spending the extra money on “designer” milk. Although we no longer receive our daily milk bottles from the milkman, we can take comfort in knowing that the decision of which milk we consume – if any – is up to us. However, with this power of choice comes the responsibility to understand the different products on the market and make conscious choices for our personal health.
The list of ultra-processed and sugary foods is getting longer and longer. Fortified milk is highly processed until vitamins and minerals are destroyed. Then add vitamins and minerals (from where?!?!?!) to 'fortify' it flavored milk add chemicals to make milk taste better condensed milk add more sugar to make it more sweet (I mean unhealthy) powdered (instant) milk water and oil don't mix. So add more chemicals so that water and oil can mix high protein milk ultra-filtered milk! my goodness!!! Avoid those high energy protein bars/drinks. NATURAL MILK PLEASE. avoid unnatural, Frankenstein milk. Better still, convert natural milk to natural yogurt.
As much as I enjoy whole milk I no longer indulge since my system gets a bit ache-y within a few hours. Which is too bad, as I do love it. And lesser types of milk (2%, skim, etc) are even worse on my system besides being nowhere near as enjoyable. Drank tons of the good stuff growing up but I guess that's one of the vicissitudes of getting older, as almost all dairy has been eliminated from my diet.
Because of the strict low-carb high-protein diet my system is ridiculously clean compared to when I essentially ate whatever I desired. My philosophy for many years was voiced by Mark Twain when he said, "Eat what you like and let the food fight it out inside." Anyway, one result of this diet is that it almost immediately shows me discomfort when I introduce what are now foreign items. As I mentioned that includes some daily products like whole milk which causes an ache in the abdominal area. It's not ruinous on any level, only lasts a couple hours, but is annoying to the point of not being worth it.
All I know is that I drank milk my entire life (ie, in cereal, with desserts and various sandwiches like pb&j, etc.) and there were no issues that I noticed. I attribute that to my body being accustomed to a wide, and constantly varying, assortment of different foods. IOW, if there was any mild complications it was masked by the generally changing state of my metabolic health. So either the issue has always been there and got lost in the "mix", or I recently developed a lactose intolerance, or my system is currently much more sensitive to slight variations in diet. Another for instance is that cheese now tends to cause mild constipation whereas I ate cheese with abandon throughout my life. In short, the ketovore/carnivore diet tends to impose some pretty strict standards and exacts a price if I vary.
Okay, possibly. I'm just wondering if that's a good thing for your gut microbiome. If you feel adventurous, you could try lactose-free milk and see how it goes. I'm quite lactose intolerant and have been all my life. I drink lactose-free skim milk (in my homemade milkshake), and I really like plain, fat-free Greek yogurt, mixed with some unsweetened baking cocoa. But I know it's not to everyone's taste. And it's quite the "in" thing to blast dairy these days. In any event, most of the hormones in dairy are found in the fat content, so I sidestep that hurdle for the most part.
Never considered that, thanks for the idea. I wouldn't go for the skim milk variety as it's the fat in milk, for one thing, that makes it so tasty and satisfying (eg, why I prefer whole milk). My system has fully transitioned from carbs to fat as my source of energy. I realize that's counterintuitive to most as we are all trained to believe that eating fat is not good for us and will, in fact, make us fat. Neither is true, but that's a conversation for another time. In any case I will see if I can track down lactose-free whole milk and give it a go.
The most common lactose-free whole milk I see in my travels is Fairlife. It comes in 52-oz square-looking plastic containers, and is now found in every major supermarket chain.
