What Pesticides can Do to Farmers’s Crops

Pesticides are chemicals that kill pests. Farmers often use pesticides on crops to kill unwanted pests, including insects and rodents, to prevent them from destroying crops. Farmers choose chemical pesticides to protect their crops because it is economical. The benefits from using pesticides, in terms of crop yield, outweigh the costs of using pesticides.

When the first synthetic chemical Pesticides was developed the pesticide in 1939. It was DDT. It proved effective against the Colorado potato beetle, an insect that was destroying crops across the United States and Europe. Then many farmers use synthetic chemical pesticides, organic farmers sometimes use naturally occurring chemical pesticides on crops to control pests.

Farmers always use chemical pesticides to protect their crops. Insects such as beetles and worms can easily infest and destroy crops. Rodents also cause damage to crops both while they are growing and in storage. But using pesticides allows farmers to kill the pests without destroying their crops. Using pesticides can help a farmer profitably produce a crop in an area where he otherwise could not or to extend a growing season.


Pesticide use can help to extend the shelf life of a food or maintain product quality. In some cases, pesticides can protect human health. That is the case with organisms on plants that can cause toxins in the plants. Among those potential toxins is ergot, a fungus that infects some grains and produces a toxin. When eaten in sufficient quantities the toxins cause ergot poisoning.

Farmers use pesticides because they act fast, quickly knocking out pests before the pests can destroy much of the crop. In addition, many pesticides are broad spectrum so they protect crops against more than one pest, which saves time and money. Using pesticides is also less labor intensive than the biological controls used by organic farmers such as crop rotation, companion planting, hedge rows between fields and not planting large amounts of unbroken acreage in any one crop or plant species.

But pesticides can help to protect crops and it may remain in the plants when farmers sell them to people, these pesticides is not easy to remove if farmers used it too much during the growth of crops. So it is quite important to choose the vegetables and fruits without pesticides or too much pesticides on them. Too much pesticides on food can lead to a bad healthy to our body. If you are not sure to tell which kinds of food are safe to eat, you can use Greentest nitrate detector to test it, it will shows you the pesticides(nitrate) level in quickly time and shows you it is under the safe control or not.

The Effects of Nitrate to Our Body

Many of us may know that nitrate and nitrites can cause cancer, tumors and other diseases. And we are affarid of it. But do you know, in our daily life we found nitrate everywhere. Nitrates are found naturally in the environment — mineral deposits, soil, fertilizers, seawater and even the atmosphere — from which they enter the food you eat and the water you drink. In fact small amounts of nitrates won’t hurt you, But you need to control the intake of nitrate safe upper limits. In here, we will give a completed introduction of nitrate and what it can do to our body.


The source of Nitrate

Nitrate are found in the soil, water and atmosphere and also in our food like fruit and vegetalbes. Higher nitrate level may found in preservatives such as hot dogs and deli meats.Your body even makes small amounts of nitrates. If you’re sick or have an infection, your body produces more.

Nowadays, some food like vegetables and fruits may contain higher nitrate level than before.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, which is also a representative food safety problem.

The Effects of Nitrate

our body converts nitrates from the food you eat into nitrites. And these nitrites combine with compounds called amines, producing cancer-causing nitrosamines. Foods containing amines include meats, fish, cheese, vegetables and wines. Foods containing antioxidant vitamins C and E block the formation of nitrosamines. Cooking or freezing foods can also reduce or inhibit some amines.
Nitrate can cause cancer problem. Most studies linking nitrates to cancer are from animal studies in which the animals were given extremely large doses of nitrates plus amines. Most people don’t consume such large amounts. However, a study published in 2011 in the “European Journal of Cancer Prevention” asked participants to fill out surveys regarding how often they ate processed meats.The results showed that people who ate more processed meats were more likely to develop several types of cancer, including stomach and colon. The EPA reports that conflicting evidence exists when it comes to whether nitrates cause cancer.


Nitrate can also cause Blue Baby Syndrome disease. You many heard blue baby syndrome in somewhere before. Yes, it was caused by high nitrate intake to the body of baby.Nitrites converted from nitrates change normal hemoglobin – the part of your blood cells that carries oxygen — into methemoglobin. Methemoglobin can’t carry oxygen, so your body becomes deprived if too much builds up. Infants are particularly susceptible because they convert twice as much nitrate into nitrite as adults. Infants exposed to large amounts of nitrate, usually from contaminated water used to mix formula, may develop “blue baby syndrome.” The lack of oxygen causes their lips, eyes, mouth, hands and feet to turn a blue-gray color. For this reason, the EPA has set limits on the amount of nitrate allowed in water.

Nitrate can cause heart disease. Nitrate is one of several metabolites in your body that reduces blood pressure and fights heart disease. It widens and relaxes your arteries, making it a useful medication for people experiencing angina, or chest pain. Scientists need more research to determine a safe amount of nitrate consumption for heart health benefits without increasing your risk for cancer and other diseases.


Control the Level of Nitrate intake to our body

We can not control the produce of nitrate, but we can control the intake of nitrate to our body, for our healthy, it is trongly recommend that when buying foods, check the nitrate level make sure they are in a safe control level.Greentest nitrate tester is a portable tool for you, it can quickly shows the nitrate level of fruits and vegetables nitrate level and shows you whether thay are safe to eat or not.

Inquire here if you need to buy Greentest, we have Greentest and Greentest Eco, Greentest eco is radiation tester and nitrate tester, Greentest is only nitrate detect.



How to reduce the harm of nitrite in food

Excessive nitrite in food is one of the causes of human poisoning, cancer and death. The problem of excessive salt in the food has aroused great concern of the scientific community.In order to prevent nitrite poisoning, in growing vegetables, nitrogen fertilizer application to timely and appropriate, in China’s largest wholesale vegetable market is rapid detection procedures, so we try to formal markets and supermarkets to buy vegetables, and make sure to avoid the excessive nitrate of vegetables. Here is a completed guide on nitrate in vegetables.

Family edible vegetables, but also pay attention to fresh, for storing vegetables with plastic bags, fastening the bag into the refrigerator, as soon as possible to eat; leftovers before eating to fully heated, in the heating process can oxidize nitrite. Should eat pickled foods, such as pickles, salted fish, ham and sausage, do not eat rotten food.

nitrate in food

Mg C900, due to higher studies have showed that the nitrate content of vegetables by boiling the nitrate content reduced by 60% to 70%. Nitrate is soluble in water and food with boiling water Cheuk can reduce nitrate content, and cut the more thin, the shorter, the more fresh vegetables, Cheuk good effect. In addition, the majority of antioxidants such as vitamin C, e and tea polyphenols have obvious inhibition of nitrosation reaction, take vitamin and urinary nitrite amine content decreased 60%. Vitamin E can prevent inferior saltpetre amine formation has anti-cancer effects. Ginger extract on nitrite has a clear role.

Mentioned above, the tea polyphenols on the human body has many benefits, tea contains large amount of tea polyphenol. A large number of studies show that N-nitroso compound in the synthesis of all kinds of tea were blocked, the higher content of tea polyphenols of tea, clear the role better. Under the same concentration of tea polyphenols of green tea extract liquid or fresh tea leaves leaching solution is better than that of pure tea polyphenol, indicating that green tea and fresh tea leaves as a composite system, the leaching solution in addition to containing tea polyphenol and vitamin C, carotene and reducing sugar composition of synergistic effect.

A study compared the green tea, oolong tea and other eight kinds of tea brewing under different concentrations of tea on nitrite scavenging. The results showed that the solid-liquid ratio of 1: 50 to 1: 100 for tea better concentration and scavenging effect on nitrite with the concentration of tea increased and increased. Most kinds of tea in the high concentration of lost scavenging effect, therefore, is to drink less tea. Such as the habit of drinking tea, it is best to drink Tuo tea or oolong tea.

To buy your food, you can use Greentest nitrate tester to check the nitrat and radiation level of it before buying them, make sure the nitrate level of your food is under the healthy control.



Food that in High level of Water Content

In hot summer weather, we will lager amount of sweat. And due to much sweat we will need to recharge our body water content, in fact,in addition to drink water, the source of food is quite important to supply body water content. Below is the list of food thant contain high level of water content. And here you can learn what kind of food that good your black hair.

High Water content of common foods:



Water content 96.7%. Cucumber is the best food for your summer replenishment and its moisture content is all the food in the highest. Cucumber can make a salad, can also be made into a dish. With cucumber, yogurt, mint and ice together to make iced drinks are also a good choice.


Water content of 95.6%. Usually, nutritionists are more willing to recommend high fiber vegetables such as spinach. But when it comes to pay, lettuce to a lot higher than they are. The lettuce sandwich or other entrees as a side dish to eat, when summer comes, is very healthy replenishment methods.


Water celery water 95.4%. Energy is very low, but it contains a lot of water and dietary fiber can effectively inhibit appetite. In addition, celery is also rich in folic acid, vitamin C and vitamin K. because celery contains a lot of water, it can neutralize stomach acid, effective in the treatment of stomach burning heat symptoms.


Water containing content 95.3%. The water radish very suitable for spring and summer to eat, it has a sweet and spicy taste, bright color and crisp texture, very suitable for eat together with other vegetables salad.


Water content of 94.5%. tomato is a good replenishment of food, if the grapes, cherries and other food with eating, replenishment effect will be better.

Green peppers

Water content of 93.9%. All fresh peppers contain large amounts of water, especially green peppers. Antioxidants it contains less than other peppers. If tired of carrots and celery and other vegetables salad, maybe green peppers can give you some change.

Is Nitrite good for the body?

We have recently heard many children because of eating excessive nitrite and lead poisoning death events, nitrite intake is carcinogenic, but in fact, nitrite, to a certain extent, is good for the body health?

We may heard that overnight food cannot eat, because of the high nitrate. However, vegetables in the refrigerator overnight and nitrous acid salt content can increase the number?


For research, we put the making food to refrigerator, the next day we found that the nitrate level is increased from 3 mg / kg to 7Mg / kg. In fact, the numerical completely is not up to the can cause the level of health concern.

The nitrite is created by vegetable enzymes or bacteria produce enzymes, reduction and produce. Vegetables absorb the nitrogen in the soil, easy to nitrogen to nitrate of vegetables, and then to synthesize amino acid and protein.

In all kinds of vegetables, and dark green leafy vegetables contain nitrate the highest, so people are most worried about they are not fresh after the producing of nitrite. Even more, it is also worried that nitrate in the human body is reduced to nitrite caused trouble, so it worked out for a day when the upper limit intake of nitrate.

However, these years of Science and news, people might have fond that nitrat in a sense, actually on the cardiovascular system is quite good. Nitrite itself is a very strong vascular expansion agent, it role in vivo can play to the vascular patency and improve blood flow, hence dietary intake nitrates, converted into nitrite in the body, for cardiovascular disease have positive significance.

Studies have shown that dietary intake of nitrates, beneficial to help the body to control blood pressure, a 2010 study found that the addition of nitrates in the diet, can effectively reduce blood pressure. For example, Westerners often suggest three patients drink fresh vegetable juice and so on, in fact, is not in order to supplement vitamin C, and to a large extent is supplement of potassium and nitrate.

Researchers to hypertensive patients taking different content of potassium nitrate, or give them taking different nitrate content in beetroot juice, found that use large amounts of potassium nitrate and taking a lot of beetroot juice as, can effectively improve the nitrite content in the blood, and actual effect of lowering blood pressure, this effect in male patients is more obvious.

Studies have found that taking nitrates can to certain drugs caused by damage to the heart of produce protective effect, play a protective role on the high salt diet caused by kidney damage. Sports nutrition research found, taking nitrate rich drinks can improve movement of oxygen uptake capacity, delaying fatigue in coming.

Why researchers is to use nitrate, rather than the direct use of nitrite?? this is because nitrate is safe and non-toxic. It will increase the blood vessels in the nitrite concentration, but did not reach the degree of nitrite poisoning caused. In healthy people of the stomach, it will not produce a large number of carcinogenic nitrosamines. If the direct use of nitrite per day reached a level of 1000 mg. It is more dangerous.

So if we control the nitrate intake to our body everyday, espercially for children and old man, it is no so dangers for nitrate itself. When buying vegetables, you can use nitrate tester to check the nitrate level, it will show you wehter the food in under the control of healthy level.

5 Best Foods for your Brain

What does the food you eat have to do with how your brain functions? We’ve always known that what we eat affects our bodies and how we look, scientists are also learning more and more that what we eat takes a toll on our brains.

Here we are talking about the healthy eating and living to protect our heart. There’s a lot of misinformation about what to eat for a healthy heart.


Salmon and other fatty fish such as sardines and mackerel are the superstars of heart-healthy foods. That’s because they contain copious amounts of omega-3 fatty acids, shown in studies to lower the risk of arrhythmia and atherosclerosis and decrease triglycerides. The American Heart Association recommends eating fish and preferably fatty fish at least twice a week. Omega-3 fatty acids are also available as dietary supplements.



Oatmeal is high in soluble fiber, which can lower cholesterol. “It acts as a sponge in the digestive tract and soaks up the cholesterol so it is eliminated from the body and not absorbed into the bloodstream,” says Lauren Graf, a registered dietician and co-director of the Cardiac Wellness Program at Montefiore Medical Center in New York City. Graf recommends avoiding instant oatmeal, which often contains sugar, and heading instead for old-fashioned or even quick-cooking oats. Other whole grains such as bread, pasta and grits are also good for the heart as long as they still contain the entire grain.

Benefits of Eating Corn

Corn is rich in vitamin C, etc. It can help you extend life span, make you more beauty, good at your eyesight, prevention of coronary heart disease and hypertension etc.. The nutritional value of corn is very high. The uutritional of corn as following:

Prevent heart disease and cancer

In the year long study, the experts compared of corn, rice, wheat, and so on a variety of staple food, nutritional value and health effects. It was found that the dimension of corn in vitamin content is very high,  is the rice and wheat 5-10 times.



At the same time, corn contains a large number of nutritional substances also let experts surprised. In addition to containing carbohydrates, protein, fat, carotene, corn also contains riboflavin, vitamins and other nutrients. These substances to prevent heart disease, cancer, and other diseases have great benefits.

The study also showed that special corn nutritional value is higher than common corn. For example, sweet corn protein, vegetable oil and vitamin content is 1-2 times higher than normal corn; “life element” selenium content is 8-10 times higher; it contains 17 kinds of amino acids, 13 species than ordinary corn. In addition, fresh corn moisture, active substances, vitamins and other nutrients are also much higher than the old mature maize, because in the storage process, the nutrient content of corn will decline rapidly.


Each 100 grams of corn can provide nearly 300 mg of calcium, almost with the dairy products contained in calcium almost. Rich calcium can play the effect of lowering blood pressure, if the daily intake of 1 grams of calcium, 6 weeks after the blood pressure can be reduced by 9%. In addition, contained in corn carrot pigment, is absorbed by the body can be transformed into vitamin A, it has anti-cancer effect; plant cellulose can accelerate the carcinogenic substances and other poisons discharged; natural vitamin E is a promote cell division, delay aging, reduce serum cholesterol, prevent the function of skin lesions, but also reduce the arteriosclerosis and cerebral functional decline.

Researchers pointed out that corn contains the corpus luteum element, zeaxanthin can fight aging eyes.  What’s more, eating corn can inhibit cancer drugs on the human side of the body, stimulate the brain cells, enhance the human brain and memory.

Protect eyesight

According to a study of Harvard University in 1994, the United States medical school and many research center to work together, uptake higher amounts of the corpus luteum prime and zeaxanthin, reduce the risk of age-related macular lesions in the probability of 43%. Corn contains lutein, zeaxanthin, especially the latter content is abundant, so corn to say is an excellent anti-aging eye supplementary food.

Reduce cholesterol

American researchers in the study also found that regular consumption of corn bran and corn oil is very beneficial to reduce the body’s cholesterol. They had selected an average age of 55 70 elderly, the cholesterol content of 50 men and 20 women, these people are relatively high hospitalized and treatment time are more than 2 years and effect is not ideal.

The researchers put corn after fine ground research, and assist with garlic powder, black pepper, celery and other condiments, with tomatoes or soup to reconcile into food, test of one and a half months per person per day to eat 20 grams, after a half months each day to eat 40 grams, after three months again after inspection found 70 people in the blood triglyceride decreased, 60 individual cholesterol reduced.

Not to Drink Processed Fruits and Vegetables Beverge


As we all know that, fruits and vegetables are good to our body healthy, and eat them every day can keep our body. Espercially fresh vegetables and fruit is very helpful for our body to remove the toxins.  But we may see that there are many drinks on the market which made by processed fruit and vegetable,  the effect of these kinds of drink is just the opposite, it will affect the discharge of toxic substances.

Fruit and vegetable juices in the process lost a lot of dietary fiber, dietary fiber to maintain a healthy digestive system is very important, in the prevention of cardiovascular disease, cancer, diabetes and other diseases can also be diluted and accelerate gastrointestinal carcinogenic compounds and toxic substances discharged. While missing less dietary fiber in fruit and vegetable juices instead will affect the discharge of toxic substances.
