Microribonucleic acids (abbreviated: miRs) which are present in milk, in particular cows milk, are a serious health risk which was previously unrecognized by science as contributing to the development of the diseases of civilization, such as overweight, type 2 diabetes and cancer. Those diseases may be counteracted by inactivating undesirable biological activities of the miRs of milk by removing and/or destroying milk exosomes which are 50-100 nm in size that transport the miR. This is accomplished firstly by treating the skimmed milk fraction with 20 kHz ultrasound and/or removing the milk exosomes by immunoadsorption thereof and/or addition of RNAses before further conventional milk processing. This milk treatment serves the purpose of reducing activities that are harmful to health of the miR-mediated genetic signal systems of milk to long-term consumers and thereby improving product safety of milk and further processing products thereof.
