These Popular Tea Brands Possess Dangerously High Levels of Pesticides!

The use of pesticides to control pests has become a common practice over the past few decades. In fact, pesticides are used literally everywhere. They are not only used in agricultural fields, but also in forests, roads, homes, buildings, schools, and parks. Unfortunately, pesticides are present in the water you drink, the food you eat, and the air you breathe.

You think you are protecting yourself from these harmful chemicals by filtering the water you drink a pitcher at a time, or purchasing organic vegetables and fruits. But, are you familiar with the fact that dangerously high levels of pesticides were found in certain popular tea brands? Some of these tea brands include Twinings, Lipton, and Tetley.

Dangerously High Levels of Pesticides Were Found in Certain Tea Brands

CBC News carried out research to examine the pesticide levels of certain large tea-manufacturing companies. These tea-manufacturing companies included:

  • Signal
  • King Cole
  • Uncle Lee’s Legends of China (Jasmine Green Tea and Green Tea)
  • No Name
  • Red Rose
  • Twinings
  • Tetley
  • Lipton (Yellow Label Black Tea and Pure Green Tea)

CBC researchers actually used the same testing method used by the national Food Inspection Agency in order to examine the pesticide residue on the dry tea leaves.

The results showed that about half of all the teas tested possessed pesticide residues, which were higher than the legal limit. In addition, 8 out of the ten teas tested also possessed several chemicals, whereas one tea brand possessed about 22 different kinds of pesticides.

Moreover, some of the pesticides found in the tea, like monocrotophos and endosulfan, are now in the process of being banned in a few countries.

Studies have proven that pesticides can increase the risk of numerous health issues, including nausea, headaches, hormone disruption, reproductive harm, cancer, and more.

Long-term exposure to different sources of toxic chemicals, environmental pollutants, medication, processed foods, and alcohol has a negative impact on your liver and detoxification systems. So, the best way to avoid this pesticide exposure is to use organic or wildcrafted loose leaf tea.

The Following Tea Brands Contained the Highest Pesticide Levels:

Even though most of the tea brands tested possessed traces of pesticides, some brands possessed dangerously high levels of pesticides. The following the brands contained the highest levels of pesticides:

– King Cole

King Cole is a tea brand that contained multiple pesticides, such as monocrotophos that could lead to irregular heartbeat, involuntary defecation, and even coma.

– Uncle Lee’s Legends of China (Green Tea)

This brand type possessed more than 20 different kinds of pesticides, such as endosulfan. The ingestion of endosulfan has been associated with tremors as well as many other negative effects on the nervous system. That’s not all, in some cases, consuming foods that contain this pesticide led to death.

– No Name

It possessed about 10 different kinds of pesticides that could have various negative health effects.

The results showed that out of the ten different tea brands tested, Red Rose was the only tea brand that did not contain pesticides.

So, you may want to avoid buying teas that contain high amounts of pesticides, including No Name and Uncle Lee’s Brands, and buy only from brands that possess little to no pesticides.

 Here Is How to Choose the Healthiest Tea Blend
  • Do not buy tea bags, which have windows or are transparent since this could decrease their shelf life or contribute to oxidation. Tea should be kept in air-sealed and light-free containers to keep their potency and freshness.
  • You may want to look for the experts behind the tea blends. In case they are tea specialists, naturopathic doctors, or herbalists, they have actually used the ingredients for a specific purpose! Specifically, Wild Leaf Active Tea has a team of tea connoisseurs and herbalists that formulate their products.
  • Choose brands that use loose-packed whole leaf or loose-leaf tea because they are made with high-quality ingredients, which have various healing properties.  What’s more, loosely-packed tea could also give the tea “room to brew,” which means more of its health-promoting properties can be extracted.
  • Opt for organic ingredients to avoid exposure to pesticides.

So, you should always choose blends formulated by naturopathic doctors, herbalists, or tea specialists, and made with 100% USDA certified organic ingredients.
