any Americans, including some vegetarians, are still consuming large amounts of dairy products, and the government still encourages them in policy.

Although scientific evidence indicates that large amounts of dairy products pose potential risks to their health and are beneficial to dairy products.

Questions have arisen about their physical health.

1-Bone health

Calcium is an important mineral element to maintain strong bones. 

Our body’s bones are constantly aging and regenerating, which means that the body needs to extract a small amount of aging calcium from the bones to add new calcium. 

Therefore, our body needs to take in enough calcium to keep bones from losing density during the renewal process due to the lack of calcium. 

However, although calcium is essential for bone health, the amount of calcium that the body really needs doesn’t need to be troublesome with food.

The human body needs to consume about 600 milligrams of calcium every day.

This is easily achieved without dairy products or other calcium supplementation methods.

Dairy products and calcium supplements cannot improve bone quality.

Clinical studies have shown that dairy products have little or no benefit to bones. 

A literature published in 2005 in pediatrics showed that milk does not improve children’s bone quality. 

In recent years, the incidence of stress fractures for young girls over the past seven years.

(Conducting stress to the bone, which can cause small bone fractures or fractures) has concluded that intake of dairy products and calcium does not prevent the occurrence of stress fractures in adolescent girls. 

Similarly, an 18-year study of more than 72,000 women by “Harvard nurses” showed that increasing milk intake does not reduce the risk of fractures.

Reduce the amount of sodium absorbed in your diet, eat more fruits and vegetables, and ensure that you consume sufficient amounts of calcium from green plant foods, such as cabbage, broccoli, and other leafy green vegetables and beans.

Can reduce the risk of fracture loosening.

You can also replace milk and other dairy products with cereals and juices that are high in calcium for breakfast.

For example, soymilk and orange juice store calcium in the same amount as milk and other dairy products.

Exercise is one of the most effective ways to increase bone density and reduce the risk of fracture loosening, and research and observation have great benefits for children and adults.

People often get vitamin D by drinking milk in their daily lives.

They don’t know that vitamin D can be obtained through many other channels. 

Without vitamin D in the body, only 10-15% of the calcium in food is absorbed.

The best natural resource for vitamin D is sunlight.

Arms and legs, or both hands, face and arms, can meet the body’s needs for vitamin D for 5-15 minutes in the sun.

The length of time depends on the skin type. 

Slightly darker skin requires longer exposure to produce sufficient amounts of vitamin D. 

In winter, the temperature is relatively low and the sun cannot provide sufficient vitamin D.

During this period, the body needs to obtain vitamin D from its daily diet.

Many physical products contain vitamin D, but this trace element is not found in dairy products. 

Therefore, fortified cereals, grains, bread, orange juice, soy milk, or rice milk in the daily diet can be options for providing vitamin D. 

Vitamin supplements are also possible.

2-Fat content and cardiovascular disease

Dairy products in the daily diet, including cheese, ice cream, milk, butter, and yogurt, are cholesterol-rich and saturated fatty substances. 

High fats in the daily diet, especially saturated fats, can increase the risk of heart disease and cause other serious health problems.

A low-fat, plant-based diet that does not eat dairy products, combined with exercise, smoking cessation, and stress control can not only prevent the occurrence of heart disease, but also reverse the trend of poor heart function.


Dairy products increase the risk of many cancers, especially cancers of the reproductive system. 

Most notably, it increases the risk of prostate and breast cancer.

The risk of dairy products for prostate and breast cancer is most likely related to an increase in an insulin-like growth factor one (also called growth factor) found in milk.

Regular consumption of milk and dairy products has been shown to increase circulating levels of growth factors. 

The strongest link between growth factors and the risk of cancer has been found to be associated with prostate cancer. 

Case-control studies in different populations have shown a strong and consistent link between serum growth factor concentrations and the risk of prostate cancer. 

One study showed that men with the highest levels of growth-promoting factors in their body had a four-fold increased risk of developing prostate cancer compared with men with the lowest levels. 

In a physician’s health study of 21,660 participants for a 28-year follow-up study, researchers found that people who consumed ≥ 2.5 servings of dairy products per day had a higher risk of prostate cancer than ≤ 0.5 servings. 

Some other findings in this study also show that the risk of prostate cancer increases with the intake of low-fat milk.

The study also shows that not only the fat in dairy products, but also a large amount of dairy calcium is healthy for the prostate. potential threat.

In addition to increasing levels of growth factors, estrogen metabolites are also considered as risk factors for cancers of the reproductive system, including breast, ovarian, and prostate cancers. 

These metabolites can affect cell proliferation, cause abnormal cell proliferation rates, and lead to cancer. 

Milk and dairy products in the human diet provide the vast majority of estrogen (60% -70%) to the human body.

In a life study behind a large cancer epidemic, the respondents were 1893 women diagnosed with early aggressive breast cancer.

The study demonstrated that the higher the intake of high-fat dairy products, the higher the mortality rate high.

Even taking 0.5 servings per day significantly increases the risk of death.

This may be due to the fact that estrogen is mainly present in fats, making high-fat dairy products highly regarded.

The consumption of dairy products may also be the cause of ovarian cancer. 

This may be due to the breakdown of lactose into galactose in milk, which may poison ovarian cells.

A Swedish study demonstrated that consumption of lactose and dairy products can worsen ovarian cancer.

A similar female health study in Iowa found that women who consumed more than one glass of milk per day were 73% more likely to develop ovarian cancer than those who consumed less than one glass of milk.

4-Lactose intolerance

Lactose intolerance is widespread in the population. 

In the United States, lactose intolerance accounts for approximately 95% of the Asian population, 74% of Native American residents, 70% of the African-American population, 53% of the Mexican population, and 15% of white Kind of person. 

Patients experience symptoms such as gastrointestinal upset, diarrhea, flatulence, etc., because these people do not have enough lactase to digest lactose. 

Lactose is broken down into two simple sugars during the digestion process: glucose and galactose. 

There are active enzymes in young children that can break down galactose, but by our age, many people are not able to digest galactose. 

Because this situation is widespread, in order to avoid some untoward side effects, it is not recommended to drink milk.


There are many pollutants in milk, from hormones to pesticides. 

Milk itself contains hormones and growth factors in the bovine body. 

There are also recombinant hormones, such as recombinant bovine growth hormone, used to increase milk production in cattle. 

Once entered into the body through milk, these hormones may affect the normal hormone function of the person.

When cows have mastitis or other inflammation, they are treated with antibiotics, and traces of these antibiotics are occasionally found in milk and dairy products. 

Because mastitis is very common in dairy cows, this treatment is frequently used because the demand for dairy products requires the cow to produce more milk than is naturally needed.

Pesticides, PCBs and dioxins are examples of other contaminants found in milk. 

Dioxins in dairy products account for one-quarter to one-half of the total intake of other foods in the daily diet.

All of these toxins are not easily ruled out.

The human body may eventually damage the body’s immune, reproductive, and central nervous systems; PCBs and dioxins are also factors that cause cancer.

Other pollutants are often introduced during the processing of dairy products, including melamine, which is often found in plastics.

Due to the high nitrogen content of melamine and carcinogenic toxins including aflatoxin, it can cause kidney and urinary tract infections.

These pollutants are more dangerous because they cannot be eliminated by pasteurization.

6-Milk protein and diabetes

Insulin-dependent (type 1 or childhood-onset) diabetes is related to the consumption of dairy products in infancy. 

A 2001 Finnish study of the increased risk of diabetes genes in 3,000 infants showed that early milk intake increases the prevalence of type 1 diabetes. 

In addition, the American Academy of Pediatrics has observed that infants who do not consume milk protein for at least the first three months after birth reduce the incidence of type 1 diabetes by 30%.

7-Health issues for children and infants

Milk proteins, lactose, fats and saturated fats in dairy products pose children’s health risks and make children more vulnerable to obesity, diabetes and heart disease.

Although low-fat milk is often the first choice to reduce the risk of obesity, a study published in the Children’s Disease File showed that children who drink 1% or skim milk are less likely to develop obesity than children who drink whole milk low. 

Furthermore, recent multiple analyses have found no evidence that increasing consumption of dairy products can reduce body fat and body weight in the long term (> 1 year).

Babies are not suitable for drinking milk. 

The American Academy of Pediatric Diseases recommends that infants under one year of age cannot only feed milk.

Milk contains less iron than breast milk, which can cause iron deficiency in infants.

Acute abdominal pain in infants is another topic related to milk.

Up to 28% of babies born less than one month have abdominal cramps. 

Pediatricians have long found that milk is responsible for abdominal cramps in children. 

Now we know that if the mother drinks milk during breastfeeding, the baby will have abdominal cramps, and the cow’s antibodies can pass through the mother’s blood to reach her milk and enter the baby.

In addition, the appearance of food allergies is a common consequence of drinking milk, especially in children.

Milk is also associated with chronic constipation in children.


Milk and dairy products are unnecessary in the daily diet, in fact they are harmful to human health. 

The best healthy daily diet is to eat cereals, fruits, vegetables, legumes and fortified cereals, fruit juices

These nutritious foods can easily help you meet your needs for calcium, potassium, riboflavin and vitamin D without facing the health risks of dairy products.
