Green tea and lychee: Eden’s ingredient spotlight

green tea and lychee benefits

 

Appreciated earliest by Asian cultures not only for their taste, but also for their association with physical and spiritual well-being, green tea and lychee fruit are now enjoyed worldwide, and the perfect pair to highlight in our latest Eden's ingredient spotlight.

On top of their delicious taste, these two food sources provide a wide range of health benefits. Both are rich in polyphenols, compounds with strong antioxidative and anti-inflammatory properties, and scientists are now demonstrating that both have positive health impacts, including reduced risk for cardiovascular disease (CVD), improved glucose response, improved fat metabolism, increased general energy levels and more.

Since extracts of both seem to work even better when consumed together, scientists have formulated them into dietary supplements. Hence our synbiotic supplement here at Eden’s contains one such combined green tea and lychee extract, together with several other polyphenols and a complementary blend of prebiotics and probiotics formulated to support gut health and optimum vitality.

What are green tea and lychee?

Throughout Earth’s history, humans have optimized their health and prolonged their lifespans by cultivating the earth. Asian cultures are particularly well known for their appreciation for and use of our planet’s bounty. East and Southeast Asian inhabitants have cultivated and harvested green tea and lychee fruit for millennia.

These foods not only served as powerful tribute items, but were also well-known for their ability to rejuvenate both body and spirit. Today, both food items are enjoyed the world over and grown in a variety of warm regions, such as South Africa, Brazil, and the Caribbean. Some facts and features of each:

Green tea

  • Used as the base for a soothing hot drink
  • Derived from the tea plant, Camellia sinensis. (Any kind of tea not produced from this plant is called an herbal tea.) 
  • Comes in thousands of varieties, depending on how the tea leaves are prepared after harvest. These processing steps impact the tea’s taste and nutritional content.
  • The least processed of all teas, because the leaves are immediately dried without a withering and bruising process.

Lychee

  • A sweet-tasting fruit used in many drinks and desserts
  • Comes from lychee trees, native to countries across Asia as far west as India and as far east as Papua New Guinea and China
  • Flesh of this fruit is very sweet and safe to eat, but the skin is inedible and lychee seeds are poisonous

Health benefits of green tea and lychee

The varying tastes of green tea and lychee make it hard to believe that they can also be healthy. Yet the Asian ancestors were on to something, as research has demonstrated the following health benefits of these two food sources, leading us to use them as part of our Eden's synbiotic. 

Antioxidant-rich foods: Not all are healthy 

Antioxidants are important molecules that protect your body from the damage caused by oxidative stress. However, foods rich in antioxidants aren’t necessarily healthy for all of us.

For instance, the caffeine in green tea — which may not represent an adverse health issue for most of us — could exacerbate symptoms of hypersensitivity, insomnia, and a racing heartbeat for individuals prone to such problems. Similarly, people who are pregnant, those who have sleeping problems, and those with IBS flare ups might be advised to limit or avoid caffeine intake.

Another example: red wine. Yes, it contains the polyphenol, resveratrol, an antioxidant associated with lower risk of dying from heart disease, and yet the alcohol component certainly could not be called nutritious. The numerous medical risks highly associated with alcohol consumption — in any quantity, even “moderation” (now defined by some medical organizations as one drink or less per day, man or woman) — far outweigh any minimal benefits from the polyphenol component.   

Because antioxidant-rich foods aren’t always as healthy as they’re touted, supplements are worth considering (see our next section) as a way to consume the correct amounts and types of important polyphenols, including those found in green tea and lychee. (However, individuals being treated for cancer should be wary of any supplements containing green tea and lychee extracts, as they may render chemotherapy less effective.)

Enter Oligonol, the polyphenol-packed supplement ingredient

While antioxidant-rich drinks and foods such as green tea and lychee each have their own powerful impacts on human health, combining those two ingredients into a supplemental extract affords unique benefits. Scientists have developed a new polyphenol“Oligonol” made by linking together individual polyphenol molecules extracted from powdered tea leaves and lychee fruit. Olignol is essentially 85% lychee and 15% green tea, and it has been clinically proven to have excellent absorption, which may enhance the efficacy of multitudinal health benefits. 

Several scientific studies have revealed myriad benefits of Oligonol consumption, including:  

  • Reduced oxidative stress-induced inflammation (that can lead to organ damage):. An animal study showed that Oligonol prevented the development of diabetic renal disease, among other benefits. Diabetic mouse models supplemented with Oligonol also showed the benefit of attenuated muscle loss.

  • Improved obesity management: In lab experiments, Oligonol treatment helped restore insulin sensitivity and reversed fatty acid accumulation in liver cells. Obese male volunteers who took two 50-mg capsules of Oligonol for 10 weeks saw a significant decrease in abdominal circumference and belly fat. Oligonol can also protect against long-term organ damage induced by fat deposits. For instance, a study done on mice showed that Oligonol could reduce long-term damage of the liver arising from T2D.

  • Reduced CVD risk. A 2018 study with obese females determined that supplementation with Oligonol reduced serum triglyceride concentrations. Triglyceride concentrations in your blood, derived from fats, are a marker of CVD risk. 

  • On top of these benefits, Oligonol is generally considered safe to consume. Extensive toxicity tests have shown that Oligonol does not cause genetic mutations or any negative impacts to the liver or kidney. Even so, you should talk to your medical provider before adopting any supplementation plan, especially since certain foods and supplements might not be appropriate for everyone to consume, as we detailed in the previous section.

    Key takeaways

    While individuals with certain pre-existing conditions may need to take care with foods rich in antioxidants, their general safety means that supplementing your diet with polyphenols might just give you the boost you need to live a longer, healthier life. Green tea and lychee, food sources enjoyed the world over, contain potent antioxidant substances that have been correlated with reduced obesity, lower CVD risk, and protection from organ damage arising from oxidative stress, a comorbidity of diseases such as diabetes and NAFLD.  Now, with Eden’s, you can reap the benefits of green tea and lychee in a supplement formulation that also includes beneficial probiotics and prebiotics, as well as several additional polyphenols.
