Is your green tea safe?

Another lovely post about The profound health benefits of green tea from its high anti-oxidant level, lowering mortality rates, lowering cancer risks, and boosting immunity.

This is all well and good, but it is necessary to remember that there is a huge difference between types of green tea. The green tea from China has actually been shown to be toxic in some cases. It is always best to stick with either Japanese green tea or at least an organic green tea to insure purity.

Here’s a great summary from a supplier of Japanese green tea we use, Hibiki-An: Green Tea for Health

inflammation and green tea

The benefits of green tea continue to pile up, and this study, Omega-3s and Green Tea Can Ease Inflammation takes a look at the effects on the inflammation process. Inflammation is now considered by many to be the root of most disease including Alzheimer’s, auto-immune, coronary, and Type 2 diabetes.

We also know that green tea helps wonders in post-operative healing by reducing inflammation and, thereby, pain!

In this study participants took

a daily supplement containing green tea extract or a placebo for three months. The supplement contained 379 mg of green tea extract, of which 208 mg was epigallocatechin-3-gallate (EGCG), the principal antioxidant found in green tea.

We’ve looked at increased brain-derived neurotrophic factor (BDNF) activity, preventing dementia, and catechine, theanine etc levels, but what is the result of all that? Increased neurogensis! It turns out that some of it is making new connections for us as evidenced by Green tea extract enhances parieto-frontal connectivity during working memory processing.

Notably, the magnitude of green tea induced increase in parieto-frontal connectivity positively correlated with improvement in task performance.

When this email The Benefits of the Paleo Diet in Post Operative Care came across my desk, I was both surprised and unsurprised. Surprised from the view that more healthcare practitioners have not seen the benefits of paleo on their trade and unsurprised because I knew of those benefits first-hand.

In the summer of 2013, I had dental surgery which included an extraction. A temporary bridge was put in place while the socket healed. I returned within a week to have the site examined and later to have the permanent bridge placed. The information the dentist office gave me for “care of the site” was quite detailed including foods I might want to enjoy while I was healing and having difficulty with my mouth. The list included OJ, pudding, yogurt, jello, sports drinks, and other sugar-laden items. Being paleo, and knowing that sugar causes inflammation, I avoided all such items instead opting for real food which had been minced and continuous cups of green tea. I not only drank green tea several times per day, but I also held the warm elixir in my mouth to bathe the extraction site.

In yet another study, Green tea component upsets cancer cell metabolism, we see more benefits of drinking green tea. This particular study shows that epigallocatechin gallate or “EGCG,” our favorite active biological agent of green tea, changes the metabolism of pancreatic cancer cells by suppressing the expression of lactate dehydrogenase A (LDHA), a critical enzyme in cancer metabolism.

  • “By explaining how green tea’s active component could prevent cancer, this study will open the door to a whole new area of cancer research and help us understand how other foods can prevent cancer or slow the growth of cancerous cells.”

It’s summertime, but there’s no reason NOT to enjoy green tea when the temperatures rise. Hibiki-an supplies us with some great recipes for iced green tea.

A recent article appropriately titled, Need another reason to drink green tea? How about preventing dementia? appeared recently. The 5-year study conducted by Professor of Neurology, Masahito Yamada of Kanazawa University, looked at the connection between green tea consumption and mental health. What they found was impressive:

• Out of the 157 subjects who said they drank green tea every day, only 18, or 11.5 percent, showed mental disorders. The numbers were similar for the subset that drank green tea one to six times a week, with 29 out of 195, or 14.9 percent, having developed problems.
• In contrast, 43 of the 138 people who said they never drank green tea – a whopping 31.2 percent – displayed signs of diminished mental functions. In other words, drinking green tea daily reduced a person’s risk of developing dementia or dementia-like symptoms to roughly one-third of those who never partook of Japan’s favorite non-alcoholic beverage.

We’re HUGE green tea drinkers. From the way I talk about it, you’d think I work for one of the Japanese green tea companies. Alas, I do not. 🙂

Here is yet another study linking green tea with health benefits. In this case, brain healing properties.

• Titled, Green tea catechins potentiate the neuritogenic action of brain-derived neurotrophic factor: role of 67-kDa laminin receptor and hydrogen peroxide, the paper set out to explore green tea’s potential for increasing the activity of a nerve growth factor known as brain-derived neurotrophic factor (BDNF), essential for the growth, maintenance and survival of neurons.
