Milk. White Poison or Healthy Drink?
Kurzgesagt – In a Nutshell・8 minutes read
Milk provides essential nutrients and antibodies, with evolving lactase enzyme in humans, and while debated for health effects, concerns about pesticides and hormones are largely unfounded, with plant-based alternatives and lab-grown milk emerging as potential options.
Insights
- Humans domesticated dairy animals 11,000 years ago, leading to the evolution of the lactase enzyme to digest lactose, a crucial adaptation as 65% of the global population loses this ability after infancy, highlighting the impact of cultural practices on human biology.
- Milk, a nutrient-dense food, is debated for its health effects, with studies showing moderate consumption poses no significant cancer risk, no impact on heart disease or stroke, and potential benefits for high blood pressure, while concerns about pesticides, antibiotics, and hormones are largely unfounded due to strict regulations, emphasizing the complex interplay between nutrition, health, and societal perceptions.

Recent questions
Is milk a vital source of essential nutrients?
Yes, milk is a crucial source of nutrients like fat, vitamins, minerals, and lactose, along with antibodies and proteins for immunity. It has been a significant part of mammal diets post-birth for thousands of years, providing essential elements for growth and development.
What are the health effects of consuming milk?
Studies have shown that moderate consumption of milk does not pose a significant cancer risk, nor does it have a direct impact on heart disease or stroke. In fact, milk may offer potential benefits for individuals with high blood pressure. However, excessive consumption of milk can lead to weight gain, so it is essential to consume it in moderation.
Are there concerns about the safety of milk?
Concerns about pesticides, antibiotics, and hormones in milk are largely unfounded due to strict regulations in place to ensure the safety of dairy products. While allergies and lactose intolerance can be negative effects for some individuals, overall, milk is considered a safe and nutrient-dense food option.
What are the benefits of plant-based milk alternatives?
Plant-based milk alternatives like soy milk offer similar nutritional value to cow milk, making them a suitable option for individuals who are lactose intolerant or prefer a vegan diet. Additionally, these alternatives have a lower environmental impact compared to traditional dairy production, making them a more sustainable choice for some consumers.
How has the consumption of milk evolved over time?
Humans domesticated dairy animals around eleven thousand years ago, leading to the evolution of the lactase enzyme to digest lactose. While most infants can digest lactose, around 65% of the global population loses this ability after infancy. This evolution has shaped the way milk is consumed and produced, with new options like lab-grown milk emerging as potential future alternatives.
