The health of milk probably depends on the breed and breed of cow from which it is milked.
Milk A2 is generally considered to be a healthier choice than other types of milk.
It is claimed that this milk has many benefits and is easier to digest for people who are lactose intolerant.
However, not all doctors agree that A2 milk is healthier.
This article provides a realistic analysis of the knowledge behind Lions A1 and A2.
What is the meaning of valve A1 and A2?
Casein, or milk protein, is the largest group of proteins in milk, accounting for about 80% of all milk proteins.
Milk contains different types of casein, and beta-casein is the second largest milk protein. Beta-casein comes in 13 different forms.
Two of the most common types of beta-casein are:
Beta-casein A1: Milk from Northern European cows generally contains large amounts of beta-casein A1. Lion A1 is made from black and white cows, North Dutch, Scottish cows and North English short-horned cows.
Beta-casein A2: This milk is made from cows that belong to the English breed and the south of France. This breed includes furry cows, jerseys and limousines.
Ordinary milks contain both beta-casein A1 and beta-casein A2, but A2 milks contain only beta-casein A2.
Some studies suggest that beta-casein A1 may be harmful to some, but beta-casein A2 is a healthier choice. The controversy over A1 and a2 stems from this.
Milk A2 is produced and packaged as Milk A2 and does not contain any beta-casein A1.
Beta-casomorphine-7 is the main reason why it is believed that regular milk is more harmful than A2 milk.
Beta-caseomorphine-7 is an opioid peptide that is released during the digestion process of beta-casein A1.
Few research teams have so far confirmed the harmfulness of beta-casomorphine-7.
However, beta-casomorphine-7 has a devastating effect on the digestive system, but the extent of the breakdown and the extent to which it enters the bloodstream intact is not entirely clear.
Researchers found no trace of beta-casomorphine-7 in the blood of healthy adults who drank cow’s milk, but some studies confirm the presence of beta-casomorphine-7 in the blood of children.
Beta-casomorphine-7 has been extensively studied, but health issues are still unclear.
The following is a review of scientific evidence related to milk A1 and beta-casomorphine-7 and their association with type 1 diabetes, heart disease, infant mortality, autism and gastrointestinal problems.
Risk of type 1 diabetes
Type 1 diabetes is commonly known as pediatric diabetes and is characterized by a lack of insulin in the body.
Several studies have shown that drinking A1 milk in childhood increases the risk of developing type 1 diabetes.
But these studies were intuitive in nature and were often based on observations.
So it is not possible to prove that beta-casein A1 causes type 1 diabetes. But people who consume too much of this protein are more likely to get some diseases than others.
Animal studies have yielded conflicting results.
Some found that there was no difference between beta-casein A1 and A2. Some other studies have shown a positive effect and an effective role of beta-casein A1 in improving diabetes.
To date, no human clinical trials have been performed to diagnose and demonstrate the effect of beta-casein A1 on type 1 diabetes.
Risk of heart disease
There are two intuitive studies on the relationship between milk A1 consumption and increased risk of heart disease.
Evidence for this claim is the studies performed on rabbits. In this study, it was found that beta-casein A1 causes fat to accumulate around damaged blood vessels. In rabbits consuming beta-casein A2, this accumulation of fat was lower.
Fat accumulation increases the blockage of blood vessels and sets the stage for heart disease. But there are still contradictions in human studies in this area.
So far, two human studies have examined the consumption of A1 milk and its effect on the risk of heart disease.
One study included 15 men and women at high risk for heart disease. The study was cross-sectional, meaning that all participants received beta-casein A1 and A2 at different intervals during the study.
In this study, no adverse effects were observed on the increased risk of heart disease. Compared with beta-casein A2, type A1 had a similar effect on blood vessel function, blood pressure, blood lipids, and inflammatory symptoms.
Another study showed that casein A1 and A2 were not significantly different and had little effect on blood cholesterol.
Sudden Infant Death Syndrome
Sudden Infant Death Syndrome is one of the most common causes of death in children under one year of age.
This syndrome causes sudden death of children without any obvious symptoms.
Some researchers believe that beta-casomorphine-7 is involved in the sudden death of children.
One study found that an increase in beta-casomorphine-7 in children’s blood stopped sleep-deprived children. This condition, known as sleep apnea, has been linked to an increased risk of developing sudden infant death syndrome.
These results suggest that some children may be allergic to beta-casein A1 in cow’s milk. However, any definitive comment requires further investigation.
Risk of autism or autism
Autism is a disorder that is characterized by poor social interactions and repetitive behaviors.
In theory, peptides such as beta-casomorphine-7 could play a role in the development of autism. However, studies do not confirm the proposed mechanisms.
One study compared children who were fed cow’s milk that contained large amounts of beta-casomorphine-7 with those who were breastfed. As a result, beta-casomorphine-7 levels were found to decline rapidly in some children, but remain the same in others.
The amount of beta-casomorphine-7 consumed by children was closely related to operational and executive inability.
Another study found that drinking cow’s milk made the behavioral symptoms of children with autism worse.
On the other hand, some studies found no connection between the two.
To date, no specific clinical studies have been performed to evaluate the effects of A1 and A2 milk on humans.
Lactose intolerance is the inability to digest the sugar in milk. Lactose intolerance is one of the main causes of bloating, flatulence and diarrhea.
The amount of lactose in milk A1 and A2 is the same. However, some people feel that milk A1 causes more bloating .
However, evidence suggests that elements in milk other than lactose can cause digestive problems.
Researchers have found that proteins in milk can also cause indigestion.
One study in 41 men and women found that some milk caused more diarrhea than some A1 milk.
In addition, animal studies have shown that beta-casein A1 significantly increases gastrointestinal disorders.
Conflicts over the A1 and A2 persist.
Some studies suggest that beta-casein A1 may have detrimental effects on some people.
However, it is not possible to make a definite statement in this regard due to lack of sufficient evidence.
But it is safe to say that if your body is compatible with milk A2 more than milk A1, just use it.
