Green Tea Versus Black Tea

Tea is said to be the most popular beverage in the world. It’s been consumed for thousands of years by millions, perhaps billions, of people.

Tea has also been shown to have many health benefits. And some of these benefits are thought to be related to tea’s antioxidant properties. These properties are from its flavonoids known as “catechins.” Flavonoids are anti-inflammatory and have a range of health benefits that I talk about in this post.

Green tea versus black tea – What’s the difference?

What do green and black tea have in common?

First of all, they both come from the camellia sinensis shrub that’s native to China and India. Green tea contains slightly more health-promoting flavonoids than black tea. How is this?

The difference lies in how they’re processed.

If the leaves are steamed or heated, this keeps them green. The heat stops oxidation from turning them black. Then they’re dried to preserve the colour and flavonoids which are the antioxidants.

Hence you have green tea.

If the leaves are not heated, and are crushed and rolled, then they continue to oxidise until they’re dry. This oxidation uses up some of the flavonoids’ antioxidant power, so black teas have slightly less ability to combat free radicals than green tea does.

PRO TIP: Adding milk to your tea reduces the antioxidant ability.

Both green and black teas contain about half of the caffeine in coffee. That translates to about 20-45 mg per 8 oz cup.

Green tea versus black tea – Health Benefits

Tea drinking, in general, seems to be associated with good health.

Heart health – For one thing, both green and black tea drinkers seem to have high levels of antioxidants in their blood compared with non-tea drinkers. They also have lower risks of heart attacks and stroke. Drinking green tea, in particular, is associated with reduced triglycerides, total cholesterol, and LDL oxidation, all of which are risk factors for heart conditions.

Overall, drinkers of green and black tea seem to have a lower risk of heart problems. Green tea has also been shown to reduce risk factors (i.e., blood lipid levels) a bit more than black tea has.

Cancers – Antioxidants also reduce the risk of many cancers. Studies show that both green and black teas can reduce the risk of prostate cancer (the most common cancer in men). Also, green tea drinkers have a lowered risk of breast and colorectal cancers. Black tea is being researched for its potential to reduce the risk of ovarian cancer.

Overall, antioxidant flavonoids in tea seem to help reduce the risk of some different cancers. Green tea may have a slight edge over black tea, but both seem to be associated with lower cancer risk.

Diabetes – Both green and black teas can reduce the risk of developing type 2 diabetes. They also reduce diabetes risk factors, like elevated blood sugar levels and insulin resistance. For example, some studies have shown that both green and black teas can help reduce blood sugar levels. Other studies have shown that green tea can also improve insulin sensitivity.

Once again, green tea seems to have a slight edge over black tea, but both are blood sugar friendly (just don’t overdo the sweetener).

Conclusion

In conclusion, both green and black teas are from the same plant, but are processed differently. Green tea retains more of the beneficial antioxidants than black tea does; but both are associated with better health than non-tea drinkers.

Overall, both green and black teas are healthy drinks, and tea drinkers, in general, seem to have fewer health conditions than non-tea drinkers. Green tea seems to have a slight edge over black tea when it comes to measurable risk factors of some common diseases.

Furthermore, when you enjoy your tea, try to minimise or even eliminate adding milk and/or sweeteners; these reduce some of the health-promoting properties of tea.

The Gut-Brain Connection

The gut-brain connection. If there was ever a call for “digestive health,” this is it!

Yes, it’s true. Your gut is considered your “second brain.”

There is no denying it any more.

And because of the new scientific discoveries about the vagus nerve, the enteric nervous system, and the amazing influence your gut microbes can have, it’s no wonder what you eat feeds not only your body but can directly affect your brain.

I find it amazing (but not too surprising).

What exactly is the gut-brain connection?

Well, the gut-brain connection is very complex, and to be honest, we’re still learning lots about it!

There seem to be multiple things working together. Things like:

  • The vagus nerve that links the gut directly to the brain;
  • The “enteric nervous system” (A.K.A. “second brain) that helps the complex intricacies of digestion flow with little to no involvement from the actual brain;
  • The massive amount of neurotransmitters produced by the gut;
  • The huge part of the immune system that is in the gut, but can travel throughout the body; and,
  • The interactions and messages sent by the gut microbes.

This is complex. And amazing, if you ask me.

I’ll briefly touch on these areas, and end off with a delicious recipe (of course!)

The vagus nerve

There is a nerve that runs directly from the gut to the brain.

And after reading this so far, you’ll probably get a sense of which direction 90% of the transmission is…

Not from your brain to your gut (which is what we used to think), but from your gut up to your brain!

The enteric nervous system and neurotransmitters

Would you believe me if I told you that the gut has more nerves than your spinal cord?

I knew you would!

And that’s why it’s referred to as the “second brain.”

And, if you think about it, controlling the complex process of digestion (i.e. digestive enzymes, absorption of nutrients, the flow of food, etc.) should probably be done pretty “smartly”…don’t you think?

And guess how these nerves speak to each other, and to other cells? By chemical messengers called “neurotransmitters.”

In fact, many of the neurotransmitters that have a strong effect on our mood are made in the gut! e.g. a whopping 95% of serotonin is made in your gut, not in your brain!

The immune system of the gut

Because eating and drinking is a huge portal where disease-causing critters can get into your body, it makes total sense that much of our defence system would be located there too, right? 70% of our immune system is in our gut!

And you know that the immune cells can move throughout the entire body and cause inflammation just about anywhere, right?

Well, if they’re “activated” by something in the gut, they can potentially wreak havoc anywhere in the body. Including the potential to cause inflammation in the brain.

Gut microbes

Your friendly neighbourhood gut residents. You have billions of those little guys happily living in your gut. And they do amazing things like help you digest certain foods, make certain vitamins, and even help regulate inflammation!

But more and more evidence is showing that changes in your gut microbiota can impact your mood, and even other, more serious, mental health issues.

How do these all work together for brain health?

The honest answer to how these things all work together and make the gut-brain connection is that we really don’t know just yet. More and more studies are being done to learn more.

But one thing is becoming clear. A healthy gut goes hand-in-hand with a healthy brain!

So, how do you feed your brain?

Of course, a variety of minimally-processed, nutrient-dense foods is required, because no nutrients work alone.

But two things that you many consider eating more of are fibre and omega-3 fats. Fibre (in fruits, veggies, nuts & seeds) help to feed your awesome gut microbes. And omega-3 fats (in fatty fish, walnuts, algae, and seeds like flax, chia, and hemp) are well-know inflammation-lowering brain boosters.

Recipe (Gut food fibre, Brain food omega-3): Blueberry Hemp Overnight Oats

Serves 2

Ingredients

1 cup blueberries (fresh or frozen)

1 cup oats (gluten-free)

1 cup almond milk

1 tablespoon chia seeds

2 tablespoons hemp seeds

½ teaspoon cinnamon

1 banana, sliced

¼ cup chopped walnuts

Instructions

  1. Blend blueberries in the food processor until smooth.
  2. Mix blueberries, oats, almond milk, chia seeds, hemp seeds in a bowl with a lid. Let set in fridge overnight.
  3. Split into two bowls and top with cinnamon, banana, and walnuts.

Serve & enjoy!

Tip: Your gut microbes love to eat the fiber in the blueberries, oats, seeds, and nuts. Meanwhile, your brain loves the omega-3 fats in the seeds and nuts.

How to Improve Gut Health

Hippocrates said, “All disease begins in the gut.”

And while this may not be 100% true for every disease in every person, more and more research shows that our gut has a bigger role in many diseases than we used to think. And we’re not just talking about heartburn, constipation, diarrhoea, IBS, IBD, etc. We’re talking about all kinds of issues like allergies, pain, mood disorders, and nutrient deficiencies.

There are a lot of reasons for this. Our gut is the portal to the outside world. It’s here where we take in disease-causing bacteria, viruses, and parasites. We also take in nutrients (and toxins) through our gut. The nutrients we ingest and absorb are the building blocks of every single part of our body. We’re just learning the connections between our gut and other areas of our body, like our brain (have you heard of “the gut-brain axis”). Not just our gut per se; but, its friendly resident microbes too. These guys also have newly discovered roles in our gut health and overall health.

So, let’s talk about the roles that our gut and our gut microbes play in our overall health. Then I’ll give you tips to improve your gut health naturally.

Our Gut’s Role in Our Overall Health

Our gut’s main role is as a barrier. To let things in that should get in, and to keep things out that should stay out. Think of “absorption” of nutrients as things we want to let in; and “elimination” of waste and toxins as things we want to pass right through and out.

This seemingly simple role is super-complex! And it can break down in so many places.

For one thing, our guts can “leak.” Yes, like a long tube with holes in it, it can allow things to get into our bloodstream/bodies that can wreak havoc (bacteria, undigested food, and toxins). You name it, whatever you put into your mouth can be absorbed by your gut and get into your bloodstream, even if it’s not supposed to. And when your gut wall gets irritated, it can “leak.” When this happens, you get inflammation, which is a starting point for many diseases that don’t seem linked to the gut but have a sneaky connection there.

FUN FACT: About 70% of our immune system lives in and around our gut.

A healthy gut is not a leaky gut. It maintains its barrier and shuttles things through to be eliminated. Maintaining a healthy gut barrier is the first pillar of gut health.

If you have leaky gut and would like to heal it once and for all, contact Kate for a free 15 minute consultation call.

The second main part of your gut are the billions of friendly health-promoting microbes. Gut microbes help us digest and absorb nutrients. They fight off disease-causing microbes, make some vitamins for us, and have all kinds of other health benefits, like mental health benefits, reducing inflammation, and stabilising blood sugar.

So, keeping your gut microbes happy is the second pillar of gut health!

How to Improve Gut Health

There are a lot of natural ways to improve gut health. Let’s start with what to stop. It’s always best to eliminate the cause, so let’s stop giving our guts junk to deal with. How about eliminating added sugars, processed foods, and alcohol? Try that for a few weeks, and you may be amazed at how much better your body (and gut) feels.

Also, you may want to eliminate other gut irritants. Dairy and grains contain common compounds known to irritate some people’s guts. Sometimes you only need to eliminate them for a few weeks to see if it makes a difference for your health.

By eating nutrient-dense foods, we allow ample macro- and micro-nutrients into our gut to maximise the chance for absorption. These nutrients help our bodies build and repair our gut, and every other body part as well. Some of the most nutrient-dense foods include dark leafy greens, colourful fruits and veggies, and fish.

The Microbiome

The second pillar of gut health is our microbes. By ingesting probiotic-rich foods and drinks, we can help to replenish our gut microbes. These are found in fermented foods like kombucha, kefir, miso, sauerkraut, and kimchi. Make these a part of your daily diet.

Whole foods are full of gut-friendly fibre. Not eating enough fibre increases the risk of heart disease, cancer, diabetes, and obesity. Fibre plays lots of roles in our gut, including whisking away some of those pesky bad bacteria and toxins so they can be eliminated. Fibre also helps to feed our friendly resident microbes that help us absorb and digest our food better. What foods have a lot of fibre? Fruits, vegetables, nuts, seeds, and even cacao.

Finally, don’t forget the uber-important lifestyle factors like getting enough sleep, stressing less, and getting the right amount (and intensity) of exercise for you. It’s easy to forget some of the simple, but key links there are between what we do with our bodies and how well they function.

Conclusion

in conclusion, the function of your gut is key to your overall health. There are two pillars of gut health: maintaining a good barrier and maintaining healthy gut microbes.

The main ways to improve both of these naturally is by eating nutrient-dense whole foods. Foods filled with nutrition, probiotics, and fibre. And eliminating common gut irritants like added sugar, processed foods, and alcohol.

Probiotic-Rich Fermented Carrots Recipe

Serves 12

Ingredients

1 L warm water
4 tsp salt
4 carrots, medium, peeled, sliced

1 clove garlic, smashed (optional)

Instructions

Make a brine by dissolving the salt in water.

Place carrots into a clean canning jar, packing them in tight. Make sure to leave about 1 inch of head space at the top.

Fill the jar with brine, making sure to cover the carrots completely. Weigh the carrots down to make sure they don’t float (you can use a “fermenting weight”).

Finally close the jar and let it sit at room temperature for 1-4 days. The longer it sits, the more the flavour will develop. Feel free to open and taste.

Serve & enjoy!

Tip: Use this as a side dish, or even a snack.

Golden Milk Recipe

Turmeric is a rhizome that grows under the ground like ginger. It has a rich, bright orange color and is used in many foods. Originally used in Southeast Asia, it’s a vital component for traditional curries. You can find dried powdered turmeric in the spice aisle of just about any grocery store. Sometimes they carry the fresh rhizome too (it looks like ginger root, but smaller).

Turmeric contains an amazing anti-inflammatory, antioxidant compound called “curcumin.” The amount of this bioactive compound is around 3-7% by weight of turmeric. Curcumin has been studied like crazy for its health benefits. Many of these studies test curcumin at up to 100x more than that of a traditional diet that includes turmeric.

Health Benefits of Turmeric

There are dozens of clinical studies using curcumin extract (which is way more concentrated than ground turmeric).

Curcumin is an anti-inflammatory compound. It fights inflammation at the molecular level. Some studies even show it can work as well as certain anti-inflammatory medications (but without the side effects).

Curcumin is an antioxidant compound. It can neutralise free radicals before they wreak havoc on our biomolecules. Curcumin also boosts our natural antioxidant enzymes.

These two functions of reducing inflammation and oxidation have amazing health benefits. Chronic inflammation plays a major role in so many conditions. Including heart disease, cancer, metabolic syndrome, dementia, mood disorders, arthritis pain, etc.

Curcumin has other amazing functions too:

  • Boosts our levels of “Brain-Derived Neurotrophic Factor” (like a natural growth hormone for your brain) which is great for brain health.
  • Improves “endothelial” function” (the inner lining of our blood vessels) which is great for heart health.
  • Reduces growth of cancer cells by reducing angiogenesis (growth of new blood vessels in tumors), metastasis (the spread of cancer), and even contributes to the death of cancer cells.

Do you think these make turmeric deserve the “miracle spice” title?

How to get the most out of your turmeric

Curcumin is not easily absorbed by your gut. For one thing, it’s fat soluble. So, as with fat-soluble nutrients (like vitamins A, D, E, and K), you can increase absorption by eating it with a fat-containing meal.

The second trick to get the most out of your turmeric is eating it with pepper. Interestingly, a compound in black pepper (piperine) enhances absorption of curcumin, by a whopping 2,000%!

Conclusion

Turmeric is a delicious spice, and it’s “active ingredient” curcumin is a great health-booster.

Curcumin has anti-inflammatory and antioxidant properties which are great to bust chronic inflammation. It also has other amazing health benefits, like brain- and heart-boosting properties, and even cancer-fighting properties.

Curcumin supplements can be great for your health, but they’re not for everyone. Check the label or speak with your practitioner before taking it.

10 Anti-Inflammatory Foods

In the western world we eat a diet high in wheat, dairy, sugar. These foods can cause acidity and inflammation in the body. Our diet is high in omega 6 and low in omega 3 which can lead to production of arachadonic acid and inflammatory pathways in the body. This can lead to chronic inflammatory conditions such as arthritis and heart disease. However we have the power to reduce inflammation and feel better by changing our diet. When we include anti-inflammatory foods in our diet, inflammation and pain can be eased. Furthermore your joints work more smoothly, cell membranes are held together and immune cells produces less histamine.

Here are my recommended top 10 anti-inflammatory foods:

  1. Oily fish – is rich in omega 3 that stimulates anti-inflammatory pathways in the body, reducing inflammation. Oily fish rich in omega 3 include mackerel, sardines, salmon, anchovies and herring.
  2. Ginger – is a root herb that improves circulation in the fingers and toes. Also it can prevent nausea and reduce inflammation in the body.
  3. Turmeric -is a spice that can reduce inflammation. It decreases permeability in the blood-brain barrier to prevent brain inflammation and cognitive decline. Furthermore it fights cancer.
  4. Nuts & seeds – plant based sources of omega 3 include walnuts, flaxseed/linseed, chia seeds, hemp seeds and pumpkin seeds.
  5. Green leafy vegetables – are rich in minerals and alkalise the body, reducing acidosis and the associated inflammation. Also they are rich in vitamin C which acts as a natural anti-histamine to reduce inflammation.
  6. Extra virgin olive oil – contains the chemical oleocanthal that acts similarly to ibuprofen to reduce pain and inflammation.
  7. Garlic – this potent herb can help to reduce joint swelling.
  8. Green tea – is rich in polyphenol antioxidants and helps to reduce inflammation.
  9. Blueberries – are rich in the antioxidant quercetin that protects the body from oxidant stress, reducing inflammation.
  10. Pineapple – contains the digestive enzyme bromelain. Bromelain helps to regulate the immune system and prevent unwanted inflammation.
