Is it really a good idea for humans to consume animal milk?
Looking at the biological structure of humans, humans can digest lactose in milk only until the age of 2. After that, the ability to digest lactose decreases. This suggests that in nature, humans should not consume milk after the age of 2 (and mothers naturally stop producing breast milk around 1-2 years after childbirth as well).
Currently, there are two groups of people:
Those who can drink milk normally.
which are common in populations in the northern and central parts of Europe.
The group that experiences symptoms after drinking milk has bodies that can't produce enough of the enzyme lactase to digest lactose in milk. This group often experiences symptoms like bloating, diarrhea, and abdominal pain, and is more prevalent in populations from Africa, Asia, and South America.
So, when did humans start consuming milk from animals and why? The historical records we have today can't pinpoint exactly when humans began drinking milk from animals. However, evidence suggests that it might have started thousands of years ago, inferred from the discovery of milk fats in ancient vessels or the finding of skeletal remains of female animals groups.
But it still doesn't explain why humans began drinking milk from animals, especially when they can't digest it. Is there another reason beyond survival?
In the present, there's an ongoing debate about whether humans should consume animal milk. Both sides have strong arguments.
Those who believe "humans can drink milk from animals" argue that the discovery of milk consumption is due to human evolutionary adaptation. Currently, some human groups have no issues digesting lactose due to genetic evolution.
On the other hand, there are those who believe "humans shouldn't drink milk from animals". They suggest that humans should stop consuming milk after weaning, as our bodies naturally stop digesting lactose.
As for my opinion as someone with lactose intolerance, drinking milk from animals should be a choice, not a health recommendation (such as the common suggestion of drinking 1-2 glasses per day). Because for some, following this recommendation might do more harm than good.
Furthermore, the nutrients found in animal milk can be obtained from other sources. Calcium can be found in small fish and leafy greens, vitamin D is available from sunlight exposure, and strengthening bones and reducing the risk of osteoporosis can be achieved through physical activity and exercise.
