How healthy is your fresh fruit, vegetables, fresh meat and fish?

Fertilizers that contain necessary elements for plant growth are used for cultivating fruits and vegetables. However, misuse of production technology, usage of prohibited fertilizers, pesticides and chemicals, as well as an increased level of fertilizer concentrations in the soil can all result in a serious damage to your health. Of all the substances that are transferred to the soil from fertilizers, nitrates are one of the most harmful if consumed in excess. Continuous intake of food with a high nitrate content may lead to an elevated risk of serious diseases.

Are you being exposed to dangerous agricultural chemicals? Many farmers apply too much fertilizer. This can result in unsafe levels of fruit nitrate and vegetable nitrate content. It's especially dangerous to children.

Nitrates and nitrites in fruit vegetables meat and fish: The risk to human health

"Multiple [epidemiological] studies have found a relationship between processed meat intake and increased risk of colorectal cancer," said Amanda Cross, an investigator in the division of cancer epidemiology and genetics at the National Institute of Health. One possible explanation: "In addition to nitrate and nitrite, it is possible that there are other components of processed meats that are responsible for the associations observed with colorectal cancer."

Most health conscious people know about the dangers of pesticides in fresh fruit and vegetables. Few are aware that Meat fish fresh fruit and vegetables expose them to dangerous nitrates.

  Nitrates Pesticides

Awareness Low High
  Due to lack of regulations and consumer awareness, nitrates in fresh fruit and vegetables often pose a greater threat than pesticides  

Nitrates cause serious disease

It has long been established that excessive nitrates are harmful to health.

Excessive nitrate consumption causes blue baby syndrome and adult methemoglobinemia. Nitrates significantly increase the risk of diabetes, Alzheimer's and Parkinson's disease and certain types of cancer.

Some researchers believe that the dramatic rise in cancer of the esophagus recorded over recent decades can be attributed to excessive nitrates in fruit and vegetables.

Nitrate content in fresh produce is unregulated

Due to the dangers, most jurisdictions tightly control the nitrate content of meat products. Food producers who add nitrates to meat must comply with strict regulations and labelling requirements.

Unfortunately nitrate levels in fresh fruit and vegetables are unregulated and unchecked in most places. There are no standards for producers or labelling requirements for sellers.

This is a risk factor. Improper farming and storage methods can result in excessive nitrate content in fruit and vegetables. Because there is no testing for nitrate levels at any point in the supply chain, consumers of fresh fruit and vegetables are exposed to unnecessary danger.

"In Germany and South Africa the drinking water standard for nitrate is 4.4 ppm -- more than twice as strict as the U.S. standard of 10 ppm (Kross, et al. 1995). The European Economic Community has established a nitrate health guideline of 5.6 ppm, and studies of infants in Europe have found that three to four percent of methemoglobinemia cases in infants occurred at doses lower than 10 ppm (Sattelmacher 1964; Simon 1962). Clearly, health authorities in many other countries believe that nitrate poses an unacceptable risk to infants and children below the current EPA standard of 10 ppm." Source

Healthy eaters are most at risk

No food is ever completely safe. Even fresh fruit and vegetables can make people sick from contamination from bacteria, pesticides and other residues. Consumers are largely protected from these risks by testing and regulatory oversight. However they are not protected from excessive nitrate content in fresh fruit vegetables, meat and fish etc. There is no oversight.

Because of this negligence, health conscious people who who eat healthy amounts of raw and lightly cooked fresh foods have a greater risk of consuming harmful nitrates.

More dangerous than pesticides?

People seeking healthier food often choose produce that's grown organically without pesticides and herbicides. But that organic label can provide a false sense of security.

Fruit and vegetables certified organic may still contain high levels of nitrates, absorbed from over application of natural fertilizers such as manure. So while avoiding harmful inorganic contaminants the consumer may be exposed to unsafe nitrate levels.

Currently the only way to know your food is completely safe is by analyzing the nitrate content of the food you eat.

Nitrate levels in fruit, vegetables meat and fish can now be measured quickly, easily, and accurately with Greentest, the portable nitrate detector by our company.

GreentestEco4 is a 2-in-1 nitrate and radiation testing device. Developed using the latest in nitrate and radiation testing technology, the innovative GreentestEco4 detects nitrate levels in 64 of the most commonly consumed fruit and vegetables as well as all types of meat. Additionally, GreentestEco4 can detect the background radiation in your immediate environment alerting you to unsafe radiation exposure. GreentestEco4’s unique rapid analysis feature can tell you in just 3 seconds if your food or environment is harmful to your health.


A scientific approach to food safety
Greentest works by measuring the electrical conductivity of the fruit or vegetable matter being tested.
Lower resistance=higher nitrate content
The presence of nitrate ions in organic matter measurably increases conductivity. This measurement differs according to the ion concentration and cell structure of the fruit or vegetable under test.
Calibrated through extensive testing..
Our scientists developed the Greentest nitrate content protocols by using a mass spectrometer to determine nitrate levels in a large number of fruit and vegetable specimens.
Testing a range of specimens under laboratory conditions allowed us to establish normative levels for various fruit and vegetable species.
A high degree of accuracy


The results were applied to test algorithms which have been coded into the Greentest device. The device has been extensively back-checked against specimens that were subsequently tested with a mass spectrometer.
The device is certified to be more than 90% accurate according to third party testing.
This is more than sufficient to produce a valid assessment of nitrate content.

I found another way we can avoid those nasty nitrates. Until we found Greentest there was no way to know if fruit and vegetables were adding to my daughter's nitrate problem. - Angel, mother of a child with nitrate issues

What experts say

In order to obtain maximum health benefits from consuming the recommended intake of vegetables, it has become more and more important to ensure that the fruit and vegetables that we put into our bodies and those of our loved ones are safe by reducing nitrate and nitrite exposure as much as possible. - Priscilla Lau, Hong Kong dietitian

To ensure the maximum health benefit taken from vegetable and fruit, whether the food we eat is up to the nitrate and nitrite safety standards is more important than before.- Liyi Lau, Hong Kong Nutritionist

Nitrates occur naturally in our fruits and vegetables, a small amount isn't harmful, but our body converts an excess of nitrates into nitrites. And when nitrites get into the stomach, the acidic conditions may cause it to form nitrosamine, which is carcinogenic and may be seriously harmful to our health. According to the World Health Organization we currently ingest 10 times more nitrites than recommended amount. Eating fresh fruits and vegetables is a good thing, but you can't see the healthiest by just looking at the outside.- Dr. Robertusvan Schie, Dutch medical scientist
