Information about the nutritional value of A1 and A2 milk

What are the differences between A1 and A2 milk, and which one is better for us to consume, what is their nutritional value, and what is the advice of doctors in this regard, which one should we drink for our benefit? We want to point out their properties and characteristics.

Properties of milk Currently, A2 milk is marketed as a healthier choice than regular milk. It is claimed to have numerous health benefits and easier digestion for people with lactose intolerance.

However, not all scientists believe that A2 milk is better for health. This article describes A1 and A2 valve. A small number of studies show that A1 beta casein may have side effects in certain people
What is meant by A1 and A2?

Milk casein is the largest group of proteins in milk and makes up about 80% of the total protein.

There are several types of casein in milk, with beta-casein being the second most common. There are at least 13 different forms of beta-casein.

Beta-casein A1: Milk from cattle breeds originating from northern Europe is generally high in beta-casein A1.

A1 milk comes from breeds such as Holstein, Friesian, Ayrshire and the North of England breed.

Beta Casein A2: Milk that is high in Beta Casein A2 and mainly originates from their breed in the Iceland Channel and southern France. It includes Guernsey, Jersey, Charolais Limousin breeds.

Regular milk contains both A1 and A2 beta-casein, but A2 milk contains only A2 beta-casein.

Some studies suggest that A1 beta casein may be harmful and that A2 beta casein is a safer choice. For this reason, A1 and A2 are discussed.

A2 milk is a marketed product that does not contain A1 beta-casein.

At the end: A1 and A2 milk contains different types of protein called beta casein. Some studies suggest that A2 milk may be the healthier of the two.

Beta casomorphin 7 (BCM-7)

BCM-7 in regular milk is believed to be less healthy than A2 milk.

BCM-7 is a narcotic peptide that is released during the digestion of A1 beta-casein.

Several research groups have suggested that BCM-7 may be harmful.

Studies have shown that BCM-7 has not been found in the blood of healthy adults after drinking cow’s milk, but a small number of studies show that BCM-7 may be present in infants.

BCM-7 has been studied extensively, but its relevance to health remains unclear.

Below is a review of the scientific evidence linking A1 milk and BCM-7 to type 1 diabetes, heart disease, infant mortality, autism, and gut problems.

Risk of type 1 diabetes

Type 1 diabetes is usually diagnosed in children and is characterized by a lack of insulin in the body.

Several studies show that drinking A1 milk in childhood may increase the risk of developing type 1 diabetes.

However, these studies are observational in nature.

They couldn’t prove that A1 beta-casein caused type 1 diabetes, only that those who consumed more of it were at a higher risk of developing the disease.

Animal studies have conflicting results.

Some studies have found a difference between A1 and A2 beta casein. Other studies have shown that beta-casein A1 has either adverse or protective effects on type 1 diabetes.

So far, no clinical trials have investigated the effect of beta-casein A1 in type 1 diabetes in humans.
Finally, several observational studies have found a link between A1 milk consumption in childhood and an increased risk of type 1 diabetes. However, the evidence is mixed and more research is needed.

Risk of heart disease

Two observational studies have associated the consumption of A1 milk with an increased risk of heart disease.

This is supported by an experiment in rabbits. This showed that the consumption of beta casein A1 promotes fat accumulation and blood vessel damage. This fat accumulation was much lower when the rabbit consumed A2 beta-casein.

Fat accumulation can potentially clog blood vessels and cause heart disease.

So far, two human trials have examined the effects of A1 milk on heart disease risk factors. However, long-term effects have not been studied.

One of those studies included 15 men and women who were at high risk of heart disease.

The study found no significant adverse effects on risk factors for heart disease. Compared to A2 beta-casein, the A1 variant had similar effects on blood vessel function, blood pressure, blood lipids, and inflammatory indices.

Another study found a significant difference in the effect of A1 and A2 casein on blood cholesterol.

Sudden infant death syndrome

Sudden Infant Death Syndrome (SIDS) is the most common cause of death in infants under one year of age.

SIDS is defined as the unexpected death of an infant without a known cause

Some researchers believe that BCM-7 may play a role in SIDS in some cases.

One study found high levels of BCM-7 in the blood of infants who temporarily stopped breathing during sleep. This condition, known as sleep apnea, is associated with an increased risk of SIDS.

These results showed that some children may be allergic to beta-casein A1 in cow’s milk. However, more studies are needed before any definitive conclusions can be drawn.

There is limited evidence that A1 milk may increase the risk of sudden infant death syndrome. However, more research is needed.

Autism risk

Autism is a mental illness characterized by poor social interaction and repetitive behavior.

In theory, a peptide like BCM-7 may play an important role in the development of autism. However, studies do not support the proposed mechanisms.

One study found infants with higher levels of BCM-7 in those fed cow’s milk compared to those fed breast milk. However, BCM-7 levels decreased rapidly in some infants while they remained stable in others.

In those where these levels remained high, the BCM-7 was strongly associated with impaired ability to plan and carry out actions.

Another study found that drinking cow’s milk may worsen behavioral symptoms in children with autism.

On the other hand, some studies did not include behavioral effects.

So far, no human trials have specifically examined the effects of milk A1 and A2 on autism symptoms.

digestive health

Lactose intolerance is defined as the complete inability to digest the sugar (lactose) in milk. It is a common cause of bloating, gas and diarrhea.

The amount of lactose in A1 and A2 milk is the same. However, some people feel that A2 milk causes less bloating than A1 milk.

In support of this, studies show that lactose components of milk may cause digestive upsets.

Scientists have suggested that certain milk proteins may be responsible for milk intolerance in some people.

A trial in 41 men and women found that A1 milk may cause softer stools than A2 milk in some people.

Additionally, studies show that in rodents A1 beta-casein may significantly increase inflammation in the digestive tract.
