Why I love Guernsey Milk

What is best milk for you? 

There are a lot of choices available to the consumer.  
Most milk produced today comes from high producing Friesian (Holstein) cows. These are the characteristic black and white cattle that we associate with dairy production.

There are many other dairy producing cows, one of which is the Guernsey cow. These are brown and white cows that produce a lovely almost yellow colour milk.

One of the benefits of Guernsey milk is that it has a higher protein and butterfat content (1):
                                                Butterfat         Protein
Guernsey                                4.68%             3.57%
Friesian (Holstein)                 3.89%             3.22%
(UK NMR Annual Report 2008/2009)

Guernsey milk contains 12% more protein, 30% more cream, 33% more Vitamin D, 25% more vitamin A and 15% more calcium than average milk. In fact the rich golden colour is due to its high levels of beta carotene.
 Not to mention it tastes great (1).

We all have heard of the benefits of having milk that is predominant in the protein Beta Casein A2 versus Beta Casein A1 found in most milks. 96% of Guernsey cows carry this Beta Casein A2 (1).

Non homogenized vs Homogenized Milk - Keep it natural 

Homogenized milk has undergone a mechanical process that breaks the fat globules into smaller globules that remain suspended in the milk, preventing separation (No cream on top). This results in a change in the chemistry of the milk not only the size of the fat globules but also the whiteness of the milk, the pH of the milk and the average casein micelle size of the milk (2). Essentially milk that is more processed. 

Next time you are shopping have a closer look at what is available. At Queensland Discount Vitamins Toowoomba (KMart) Plaza they sell the most awesome non-homogenized A2 Guernsey milk.
