Milk is packed with nutrients, but it isn't the right choice for everyone. Cardiologist explains who should drink it and who may need to avoid it.

Milk has long been considered a nutritional staple, praised for its protein, calcium and vitamin content. However, not everyone digests it the same way. According to interventional cardiologist Dr Vivek Veeram Reddy, whether milk is good for you depends largely on your body’s ability to digest lactose, the natural sugar found in milk.

Can everyone drink milk?
Explaining the difference between breast milk and animal milk, Dr Reddy shared in his August 1 Instagram post, “We all consume breast milk during infancy, but after that, most of us switch to animal milk. The ability to digest animal milk varies from person to person because it depends on how much lactase enzyme your body produces.”
Lactase is the enzyme responsible for breaking down lactose. When the body doesn’t produce enough of it, people may develop lactose intolerance, making it difficult to digest milk.
Why some people tolerate milk better than others
According to Dr Reddy, genetics and ancestry play a significant role in lactose tolerance. “People from Northern India and many European populations have historically consumed more milk, so lifelong lactose tolerance is more common among them. In contrast, lactose intolerance tends to be more prevalent in South Indians, making some people more likely to experience digestive discomfort after drinking milk,” he explained.
Research has consistently shown that Northern Europeans have some of the highest rates of lifelong lactose tolerance, while South Indians have a higher prevalence of lactose malabsorption than North Indians due to genetic differences.
Symptoms of lactose intolerance
If drinking milk leaves you feeling uncomfortable, it doesn’t necessarily mean milk is unhealthy.
“If milk causes bloating, gas, abdominal discomfort or diarrhoea, it may simply indicate lactose intolerance rather than milk being harmful. In such cases, it’s worth reducing or avoiding milk and seeing if your symptoms improve,” Dr Reddy said.
Common symptoms include:
- Bloating
- Gas
- Abdominal cramps
- Diarrhoea
Dr Reddy emphasised that there is no universal rule when it comes to milk consumption. “If you’re drinking unadulterated, minimally processed milk and your body tolerates it well, there’s no reason to avoid it. It can be safely consumed in moderation as part of a balanced diet,” he said.
However, if milk consistently causes digestive issues, eliminating it is not necessarily a nutritional setback.
Can you get the same nutrients elsewhere
According to Dr Reddy, many nutrients found in milk can be obtained from other foods. “Calcium can also be obtained from foods such as almonds, although they are higher in calories. Similarly, eggs provide high-quality protein and several essential nutrients, making them a good alternative for those who cannot tolerate milk,” he explained.
He also pointed out that many people with lactose intolerance are still able to tolerate fermented dairy products because they contain much less lactose. “Curd, yoghurt, paneer, cheese and even smaller portions of milk are often better tolerated than a full glass of milk,” he added.
Dr Reddy stressed that nutrition should always be personalised rather than driven by myths or viral social media trends. “There is no one-size-fits-all diet. If milk suits your body, you can continue consuming it in moderation. If it doesn’t, there are plenty of other nutritious foods that can help meet your dietary needs,” he concluded.
