the simple process of heating the milk to pasteurized it will cause lactose intolerance and scare millions away from drinking what was once one of the safest and most nutritious ways to get required vitamins and minerals into your body. If you look back to the old times say one hundred years ago lactose intolerance was non existent. The cows that were milked back then were grass fed and mostly healthy lads and raised in comfy settings and pasteurization was only practiced in the populating cities as cows closer to these cities demanding their morning milk have to be kept corraled in tight spaces to fit more cows and the nutrition that those cows have depended mostly on grains filled with hormones to make the cows grow faster and bigger and leftover barley and oats from the distillers and beer companies who sell their leftover mashed grains to the cow companies. Sad part is that all nutrition is gone from the grains fed to them and even lost as there is nothing healthy at all about drinking beer or booze. What a waste of nutrition.
With the demand of milk growing as the population grows milk companies came up with a way to make milk safe to store for prolonged periods of time without it spoiling. Keep in mind that the milk you pored over your fruit loops this morning probably sat in a large storage facility for over a year before it was shipped out to your 7-11 that’s right around the corner. This Luis Pasteur guy created the process of heating foods to a specific temperature then cooling it after it was removed from the heat and this process dramatically slows spoilage down. Unlike sterilization, pasteurization is not intended to kill all micro-organisms in the food but it does. It aims to reduce the number of viable pathogens so they are unlikely to cause disease commercial-scale sterilization of food is not common because it adversely affects the quality and taste of the product. Certain foods, such as dairy products, may be superheated to ensure pathogenic microbes are destroyed.
Lactose intolerance occurs when the small intestine simply does not produce enough of an enzyme called lactate and your body needs lactate to break down, or digest, lactose which is the sugar found in dairy products.
Lactose intolerance generally develops in individuals as they age and people tend to become lactose intolerant around their teenage years and during adulthood. Lactose intolerance can be brought on by chemotherapy, infections, penicillin reactions, surgery, pregnancy, drinking milk that has been pasteurized.
