“Keith Woodford, in the book 'Devil in the milk', writes:
Some thousands of years ago a genetically different strain of milk appeared, now known as 'A1' milk. The original 'A2' milk is generally produced by cattle in Africa, Asia, France and Guernsey. Goat and camel milk is also 'A2'. Cattle in other countries generally produce mainly 'A1' milk. There is only one genetic difference between A1 and A2 milk, being the amino acid at position 67 in the chain of 209 amino acids that make up beta-casein protein in milk. In the case of A1 beta-casein the amino acid at position 67 is histidine, whereas with A2 beta-casein it is the amino acid proline... However this small difference results in the milk having quite a different chemical - and perhaps physiological - effect. This is because the proline forms a strong bond with the amino acids in positions 66 and 68. In A1 milk, the histidine linkage with its neighbours is more “easily broken by digestive enzymes... The breakdown of these links through digestion creates a protein fragment known as BCM7 (beta-casomorphin-7) which acts as an opiate."
The book also seeks to make a link between consumption of A1 milk and heart disease, consumption of A2 milk and longer life expectancy, as well as numerous other claims.

Talks about casein, A2 milk etc.
"This opiate BCM 7 has been shown in the research outlined in the book to cause neurological impairment in animals and people exposed to it, especially autistic and schizophrenic changes. BCM 7 interferes with the immune response, and injecting BCM 7 in animal models has been shown to provoke Type 1 diabetes. Dr. Woodford presents research showing a direct correlation between a population’s exposure to A1 cow’s milk and incidence of auto-immune disease, heart disease (BCM 7 has a pro-inflammatory effect on the blood vessels), type 1 diabetes, autism, and schizophrenia. What really caught my eye is that BCM 7 selectively binds to the epithelial cells in the mucus membranes (i.e. the nose) and stimulates mucus secretion."

So can cheese drop your b.g.? Mine was 73 fasting this morning, and 15m after 3 eggs, CO, 5+oz sausage, and an ounce of cheese, it's 61! I tested again with a different strip, different finger and got 63, so it seems to be accurate. What?
Anyway, I'm down a pound today, had VERY weird sleep last night (dreamed I was sick all. night. long, woke but fell back to sleep many times, woke at 5:30, 2hrs short of the 9hrs I usually need), and think the hair on my upper legs is coming back, too, after being gone for at least two years (dang, I was glad it was gone, lol).
