Milk’s health effects may depend on the cow breed it came from.
A2 milk is currently promoted as being healthier than conventional A1 milk. Proponents claim that A2 is healthier overall and easier to digest for lactose-intolerant people. This article objectively examines the science behind A1 and A2 milk.
What do the terms mean?
Casein is the biggest group of proteins in milk, making up nearly 80% of the total protein content.
Milk contains several types of casein. Beta-casein is the second most prevalent protein, with at least 13 different forms.
The two most common forms are:
A1 beta-casein. Milk from northern European cow breeds is generally high in A1 beta-casein. These breeds include Friesian, Ayrshire, Holstein, and British Shorthorn.
A2 beta-casein. A2 beta-casein milk is mostly found in the Channel Islands and southern France: these include Jersey, Guernsey, Charolais, and Limousin cows.
A2 milk exclusively includes A2 beta-casein, whereas regular milk has both A1 and A2 beta-casein.
According to certain studies, A2 beta-casein is safer, and A1 beta-casein may be dangerous.
The public and the scientific community disagree on these two types of milk.
The A2 Milk Company produces and sells A2 milk free of A1 beta-casein.
Adverse claims about the A1 protein
Beta-casomorphin-7 (BCM-7) is an opioid peptide released during A1 beta-casein digestion.
Some people believe regular milk is less healthy than A2 milk.
BCM-7 may be related to type 1 diabetes, heart disease, neonatal mortality, autism, and digestive issues, according to several study groups.
BCM-7 may impact your digestive system, but it’s unknown if it enters your bloodstream intact.
According to studies, healthy individuals who consume cow’s milk have not been shown to have BCM-7 in their blood, although infants may have BCM-7 according to some tests. While BCM-7 has been vastly studied, its overall health effects still need clarification.
Type 1 diabetes
Children are often diagnosed with type 1 diabetes, characterized by insulin deficiency.
According to several research, consuming A1 milk while growing up increases your risk of developing type 1 diabetes.
Heart disease
According to two observational studies, A1 milk consumption is associated with a higher risk of heart disease.
According to a rabbit experiment, A1 beta-casein enhanced fat formation in damaged blood arteries. When rabbits ate A2 beta-casein, this accumulation was significantly less.
Autism
Poor social skills and repetitive behavior are two characteristics of the mental illness autism.
The development of autism may, in theory, be influenced by peptides like BCM-7. Not all suggested mechanisms have been proven by research.
Digestive Health
The inability to completely digest milk and sugar (lactose) is known as lactose intolerance. This is a typical source of gas, bloating, and diarrhea.
A1 and A2 milk both contain the same amount of lactose. A2 milk, however, dilates the stomach less than A1 milk.
The bottom line
The possible effects of A1 and A2 milk on health are still being debated.
According to a study, A1 beta-casein may cause some unpleasant digestive issues.
The evidence is still insufficient to establish solid conclusions about the purported associations between A1 beta-casein and other disorders, such as type 1 diabetes and autism.
