How healthy are your fresh fruit and vegetables?

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 and vegetables: The risk to human health

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

Due to lack of regulations and consumer awareness, nitrates in fresh fruit and vegetables 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.

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 and vegetables. There is no oversight.

Because of this negligence, health conscious people who who eat healthy amounts of raw and lightly cooked fresh fruit and vegetables 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 fruit and vegetables are completely safe is by analyzing the nitrate content of the food you eat.

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

Now you can identify unhealthy fruit and vegetables with this portable fruit and vegetable nitrate tester...

  • Protect yourself and protect your family
  • Simply insert the probe into your sample
  • Easy-to-read test results in just 3 seconds

How It Works 

  • It only takes 3 seconds to check the health of your fruit and vegetables
  • Vegetables and fruits contains various amounts of salt ions, 98% of which are nitrate ions.
  • The Greentest probe applies a precisely regulated electrical current to a fruit or vegetable specimen.
  • The proprietary Greentest algorithm accurately calculates the specimen's nitrate content by comparing its electrical conductivity against a database obtained from exhaustive mass spectrometer testing of similar specimens under laboratory conditions.
  • The results displayed are certified to be more than 90% accurate according to third party testing more than enough to determine the safety of the specimen.

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.

Who Buys It

  • People who want to take better care of themselves and their loved ones, and especially their kids.
  • People who want to make informed healthy choices about the food they eat.
  • People who want to eat healthier with less meat and more good quality fresh fruit and vegetables
  • People who understand the problems associated with modern agricultural practises.
  • People who want to demonstrate the safety of the food they serve.
  • People who want to give someone a useful gift.

The Greentest, food safety testing device, helps people to make healthier choices about their food. The innovative device also helps people in the food business make healthier decisions about the food they choose to grow and sell. It is suitable for small-scale farmers, distributors, store owners, caterers and more anyone with a stake in serving up healthy food. Unlike other methods and equipment on the market, it's an easy to use food safety testing device with a simple interface and clear, unmistakable results.
