BST MILK and Ordinary MILK Indistinquishable? Not Really.

One basically designed to hit bacteria, the other viruses and toxins. In the event of unnaturally low exposure to bacteria (ie modern sanitary living) the virus-toxin one dominates. It becomes exquisitely sensitive and liable to over-reaction. Hence (it is proposed) both allergies and auto-immune diseases (both being very significantly higher in the first world). But isn't the reaction to ANY foreign protein the thing that is exacerbated when the immune system is not given enough to do? No, not if you are continually exposed to significant bacterial challenge as fighting them off inhibits the viral pathway. I didn't realise they were significantly different. Thanks. How do you explain the marked increase in autoimmune diseases lately? As well as food allergies and asthma like allergies? Modern hygiene clears up viri as much as bacteria. Yes, but given little to do the viral one dominates. I wonder why. After all with two mutually inhibitory systems, like a swing one will dominate (thus further inhibiting the other). I didn't realise they were so. Thanks again Probably in nature bacteria are a more common threat than viruses. It probably depends a lot on the environment/lifestyle. Intriguingly, this also posits a mechanism for the use of antibiotics in young farm animals (babies in effect) attacked by a serious virus. It is usual for them to recover from the virus, only to succumb to a bacterial disease (often scours). The switching over to viral attack, leaves their immature immune system open to attack by bacteria. This is so common as to be expected. So what was the antibiotic given for? Indeed. Prophylactically. Not a good practice routinely, I would have thought. But at least one with relevant sensitivities would be better, if the bacterial infection is routinely expected. |
