Do you find milk addictive? If so, assume an opioid-like peptide reaction. Does milk make you sneeze? If so, assume an intolerance to the immunological compounds and/or opioids, or a genuine allergic reaction – particularly if milk makes your throat itch. Does milk make you gain weight? If so, assume an opioid-like peptide reaction and/or sensitivity to IGF. Does milk provoke seizures? If so, you may need to test your reaction to calcium.
For suspected opioid-like peptide responders, individuals should test A1 milk (regular cow’s milk) versus officially branded A2 milk (Guernsey cow, buffalo, goat’s and sheep’s milk). People who are intolerant of opioids usually tolerate goat’s and sheep’s milk unless they are super-responders. See the gluten and casein responders page . Cream and Butter
Metabolism of propanoate begins with its conversion to propionyl coenzyme A (propionyl-CoA), the usual first step in the metabolism of carboxylic acids. Since propanoic acid has three carbons, propionyl-CoA can directly enter neither beta oxidation nor the citric acid cycles. In most vertebrates, propionyl-CoA is carboxylated to D-methylmalonyl-CoA, which is isomerised to L-methylmalonyl-CoA. A vitamin B 12 -dependent enzyme catalyzes rearrangement of L-methylmalonyl-CoA to succinyl-CoA, which is an intermediate of the citric acid cycle and can be readily incorporated there.
Low temperature (refrigeration and freezing) : Most organisms grow very little or not at all at 0 o C. Perishable foods are stored at low temperatues to slow rate of growth and consequent spoilage (. milk). Low temperatures are not bactericidal. Psychrotrophs, rather than true psychrophiles, are the usual cause of food spoilage in refrigerated foods. Although a few microbes will grow in supercooled solutions as low as minus 20 o C, most foods are preserved against microbial growth in the household freezer.
