A cup of milk keeps the doctor away, but choosing the wrong dairy products may cost your health.
What is the difference between all kinds of milk products on the market? Who are whole milk, low-fat milk and skimmed milk for? Do expensive dairy products have better quality?

Test-it™ Introduction

Due to increasing health awareness, people become more concerned about what they consume. As a worldwide popular drink, milk has high nutritional value. Yet, we should pay attention to its quality and safety to best protect our health.

To find out the truth, Test-it™ selected 68 most popular milk products in the market and joined hands with a professional laboratory to perform safety test using the world leading bio-testing technology Testing 2.0. Based on the test results, it rated 46 products as Green Fish (Excellent), 10 products as Yellow Fish (Basic) and 12 products as Red Fish (Sub-optimal).

Test-it™ found that the more expensive the milk, the better its quality. Samples produced in Europe and America are better in terms of safety. None of the samples contain estrogenic endocrine disruptors that exceed the standard. In other words, all samples passed the chronic toxicity test.

According to the World Health Organization and United Nations, choosing the wrong product could cause cancers, infertility, precocious puberty, obesity and neurological disorders. Test-it™ provides clear, direct test reports with lifestyle tips. Equipped with scientific and objective information, consumers can make safer purchasing choices. Stay tuned for more interesting facts.

Interesting Facts of Milk

Only imperial consorts had the privilege of having milk before the Tang Dynasty.

There is lactose-free milk for people with lactose intolerance.

Milk can neutralize capsaicin and soothe spicy tongue.

Never take medicine before and after drinking milk as calcium ions may bind with the medication and affect drug absorption.

Milk is an excellent cure for peptic ulcer as it neutralizes gastric acid.

Exposing milk to bright sunlight or light will damage the vitamins.

Test-it™ Reports

Test-it™ Standards

Traditional chemical Test 1.0 and existing regulations only reflect the basic requirements for market entry, not the products’ actual safety for consumption. Test-it™ applies first-in-the-world fish embryo toxicity (FET) test technology (Testing 2.0), enabling an effective and thorough examination on both acute and chronic toxicity in the tested products (effective up to several thousands of known toxicants to humans). We test and classify global products into three categories (Red, Yellow and Green Fish) through a comprehensive test system and scientific statistic analysis. We provide clear, direct test reports with lifestyle tips. Testing method varies with products. For the liquid milk test, the transgenic medaka embryo testing for chronic toxicants, zebrafish embryo testing for acute toxicants and ingredients check are applied.

Good performance under screening of acute toxicity, chronic toxicity and ingredients. Consumers can rest assured that the products are safe for purchase.

Meets the safety baselines under screening of acute toxicity, chronic toxicity and ingredients. Consumers are recommended to purchase with caution.

Below standard under screening of acute toxicity, chronic toxicity and ingredients. Consumers are recommended to purchase with extra caution.

Findings of Test-it™

1. Liquid milk is safer than dairy beverages.

Samples under test are categorized into two groups: liquid milk and dairy beverages.

[Milk encyclopedia] Products which contain milk as the only ingredient are classified as milk.

Products comprise liquid milk and additives including emulsifiers, stabilizers, flavorings and colorings are classified as dairy beverages.

Test-it™ found that over 70% of liquid milk samples passed the test and were rated Green Fish. Comparing with dairy beverage samples containing additives, liquid milk performed better in terms of safety.

2. Product type battle: Skimmed milk is the safest.

Samples were grouped into whole milk, low-fat milk and skimmed milk in terms of types.

Among these 68 milk samples:

There are 14 low-fat milk samples, with 11 (79%) of them rated Green Fish, 1 (7%) rated Yellow Fish and 2 (14%) rated Red Fish.

There are 46 whole milk samples, with 28 (60%) of them rated Green Fish, 9 (20%) rated Yellow Fish and 9 (20%) rated Red Fish.

There are eight skimmed milk samples, with seven (88%) of them rated Green Fish and one (12%) rated Red Fish.

3. Brand origin battle: Samples of European and American brands are the safest.

Brands of milk products under test are mainly from Asia, Europe & America and Oceania.

Among the total of 46 samples of Asian brands, 29 (63%) products were rated Green Fish, 9 (20%) were rated Yellow Fish and 8 (17%) were rated Red Fish.

Among the total of 10 samples of European brands, 8 (80%) were rated Green Fish and 2 (20%) were rated Red Fish.

Among the total of 12 samples of Oceanian brands, 9 (75%) were rated Green Fish, 1 (8%) was rated Yellow Fish and 2 (17%) were rated Red Fish.

By comparing the data for brands of different origins, Test-it™ found that 80% of European and American brands passed the bio-testing and were rated Green Fish, meaning that they are safer that brands from Asia and Oceania.

4. Where do the safest products come from? European and American products are the safest.

In terms of product origin, the test selected milk produced in Asia, Europe & America and Oceania.

Among these 68 milk samples:

46 samples were manufactured in Asia, with 28 (61%) rated Green Fish, 9 (20%) rated Yellow Fish and 9 (20%) rated Red Fish.

9 samples were produced in Europe and America, with 8 (89%) rated Green Fish and 1 (11%) rated Red Fish.

13 samples were manufactured in Oceania, with 10 (77%) rated Green Fish, 1 (8%) rated Yellow Fish and 1 (15%) rated Red Fish.

In comparing data for different product origins, nearly 90% of samples produced in Europe and America were rated Green Fish, indicating better safety performance than samples manufactured in Asia and Oceania.

5. Higher the price, safer the milk.

Samples were classified into high-priced, mid-priced and low-priced ones and the results are as follows:

Among the 68 samples tested, the most expensive one costed 10HKD/100ml, which was around 10 times of the cheapest one that costed 1.1HKD/100ml. The average price was 2.6HKD/100ml.

Through the testing of milk products, Test-it™ found that more than half of the mid-priced and high-priced samples passed the safety test. Nearly 80% of high-priced samples were rated Green Fish, which indicates that they have better safety performance.

Milk requires high standard of storage, which incur costs in every process. More refined process leads to higher costs, and at the same time, better quality. This may explain the more satisfying safety performance of higher-priced milk.

6 . Acute toxicity test: fish embryos died in some samples.

84% of genes known to be associated with human disease have a zebrafish counterpart. Therefore, substances that are toxic to zebrafish embryos are likely to be toxic to human. When exposed to toxic substances, fish embryos develop abnormalities, such as head tumour, tail tumour, heart swelling and even immediate death in serious condition.

Test-it™ found that 46 (68%) samples passed the acute toxic test and were rated Green Fish, ten (15%) were rated Yellow Fish and 12 (18%) were rated Red Fish.

Samples were also examined using the transgenic fish embryos technology to test for chronic toxicity. When chronic toxicants (estrogenic endocrine disruptors) are detected, embryos emit green florescence light in various luminous intensity, which can be used to quantify toxicants, enabling evaluation of human health risks according to WHO/FAO guideline.

It is worth noting that all 68 milk samples passed the chronic toxicity test and none of them exceeded the standard for estrogenic endocrine disruptors.

[Milk Fact] There are many factors affecting the quality of fresh milk, including residual pesticides and mildew in livestock feeds, medication of the cows, quality of containers for milking, processing and storage, logistics and packaging. All steps in the production process may affect milk quality and become the major sources of harmful substances in the milk products.
