A2 milk has less gastrointestinal symptoms even though it has the same amount of lactose as A1 milk, according to qualified dietician Garima Goyal.
The question of whether milk can make one sick has been one of many that experts have received as a result of the increased awareness of food intolerances. Dietitian Anjali Mukherjee addressed these worries by writing on Instagram, “Growing up, we were all taught one thing, milk is fantastic for our health, especially if we want strong bones and teeth. That being said, many people have through time developed various intolerances and other problems related to milk. As a result, experts have started investigating the potential causes of this.
She asserts that a protein fragment known as A1-beta-casein, which is present in ordinary cow milk, may contribute to several health issues. Mukherjee went on to say that A2 milk is the “healthy milk” because it does not contain the mutated A1-beta casein. “This protein has been linked to various health issues such as cold, congestion, sinus, fatigue, inflammation, body stiffness, type 2 diabetes, autism, and other neurological problems,” she continued.
She was careful to point out that it is still unclear if this mutation affects everyone or just some people, if it affects everyone slightly and builds up over time, or if it only affects some people. She went on to say that selective breeding, or only breeding cows that produce A2 milk, can be beneficial.
We contacted registered dietitian Garima Goyal to learn more, and she stated to indianexpress.com that the information currently available is “insufficient and inconclusive.” The key contributing component is the release of a peptide called beta-casomorphin-7 (BCM-7), which can lead to digestive problems and inflammation in the gut. Researchers have discovered a connection between type 1 diabetes and A1 beta-casein and have found that ingesting A1 milk as a child increases the likelihood of developing the disease. Since these studies are just observational, it is still uncertain whether A1 casein is the primary contributing component, according to the researcher.
What Distinguishes Milk Grades A1 and A2?
There are two varieties of beta-casein in typical cow’s milk: A1 and A2. The modified A1 beta-casein is no longer present in marketed A2 milk; instead, only the A2 beta-casein is present. The question of whether A1 beta-casein is more detrimental than A2 casein is at the centre of the scientific discussion surrounding the healthiest milk, according to Garima.
A 2019 review by the National Center for Biotechnology Information (NCBI) found that human-based evidence from clinical trials and epidemiological studies published before October 2017 has low or very low certainty for other health effects but moderate certainty for adverse digestive health effects of A1 beta-casein compared to A2 beta-casein.
A1 milk is linked to a risk factor for human health risks since it may “possibly influence various opioid receptors in the brain, endocrine, and immune system,” according to Komal Patel, clinical nutritionist, Fit India Ambassador, and founder of Diet Studio. It is also known to be an oxidant of low-density lipoproteins (LDL), and it is thought that LDL oxidation is what causes arterial plaque to form. As a result, drinking beta-casein A1 milk raises your risk of developing type 1 diabetes, coronary heart disease, and arteriosclerosis, according to Patel.
What Food Should One Eat?
Milk is a healthy source of calcium and protein if you are doing well, according to Dr. Abhinav Gupta, specialist in gastrology at Narayana Multispeciality Hospital in Jaipur.
“Milk contains a little amount of acid, but it is significantly less than the gastric acid that the stomach normally produces. While research has shown that milk boosts acid production, which might make you feel sick again if it doesn’t fit you, it does temporarily help to absorb gastric acid, according to Dr. Gupta.
According to Goyal, people have reported experiencing fewer stomach discomfort after ingesting A2 milk even if the amount of lactose in both types of milk is the same. The question of whether there are any other milk constituents that can result in symptoms and pain in the abdomen is still being researched. A2 milk is definitely worth a try for anyone who have digestive problems after consuming milk, she said.
A2 milk includes the same amount of lactose as regular milk, therefore those who are lactose intolerant cannot consume it, according to Goyal. Those who are allergic to milk will also be allergic to A2 milk.
