This concern has led to hesitation in offering cow’s milk and formula milk to children, which could negatively impact their overall development.
Cow’s Milk and Formula Milk Do Not Cause Early Puberty
Trương emphasizes that the notion that drinking cow’s milk or formula milk can lead to early puberty in children is entirely misleading. In reality, the hormones present in cow’s milk, which aid in milk production for cows, have no impact on the human body.
Trương, an expert in this field, clarifies that these hormones are completely digested and processed by enzymes in the stomach, intestines, and pancreatic juices, rendering them inert in the human body.
He further explains that the hormones in milk are neither estrogen nor testosterone, nor are they sex hormones. Therefore, consuming cow’s milk and formula milk does not induce early puberty. “Let’s stop blaming cow’s milk and formula milk,” he asserts.
Numerous global studies have been conducted on this subject, and scientists have found no evidence linking early puberty in children to the consumption of formula milk, powdered milk, or cow’s milk. So, if a mother faces challenges in breastfeeding, opting for formula milk is a reasonable choice for the child’s nutrition.

However, Trương also advises that milk intake should be within appropriate limits for each age group. For children under one year old, milk is the primary source of nutrition, while children over one year old should not consume more than 500ml of milk per day.
This recommendation is not only to prevent early puberty but also to ensure a balanced diet and comprehensive development for the child. Research indicates that excessive milk consumption can limit children’s opportunities to explore a diverse range of foods, leading to the risk of malnutrition and rickets, which are detrimental to their health.
Primary Factors Contributing to Early Puberty in Children
Genetics
According to MedlinePlus, a service of the US National Library of Medicine, the most common genetic cause of early puberty is a mutation in the MKRN3 gene. Researchers also suspect that alterations in other yet-to-be-identified genes may be associated with this condition.

Overweight and Obesity
Unhealthy eating habits, such as consuming fast food, coupled with a sedentary lifestyle that involves excessive screen time on phones, TV, or iPads, contribute to overweight and obesity in children.
These conditions can increase the risk of early puberty. Research from WebMD indicates that fat cells in the body produce leptin, a crucial hormone. The more fat cells there are, the higher the leptin levels. This hormone plays a vital role in regulating appetite, maintaining body shape, and influencing reproductive functions.
While leptin does not directly trigger puberty, studies have shown that children need a certain level of leptin in their bodies for puberty to occur. Therefore, girls with higher leptin levels due to being overweight tend to experience early puberty.
Use of Cosmetics and Plastic Products
The frequent use of everyday products like shower gel, shampoo, nail polish, and plastic food containers can lead to endocrine disorders, which are among the causes of early puberty.
Animal studies have revealed that several chemicals are associated with early puberty, such as phthalates, commonly found in fragranced products like perfume, soap, and shampoo; parabens, used as preservatives in many cosmetic products; and phenols, including triclosan.
Many parents may not pay attention to their children using soaps, shampoos, or even cosmetics like adults. This warrants reconsideration and restriction to prevent the risk of early puberty in children.
