Par Mélina Da Rocha

When I discovered matcha tea, I was immediately interested in what it could do for my health. As I researched the subject, I realized that the key to many of its benefits lay in polyphenols. You've probably heard of them, but do you really know what they are, their benefits, and in which drinks or foods they can be found? That's what I'm going to share with you today.

Polyphenols: the benefits at a glance

Polyphenols are natural antioxidants that are essential for the proper functioning of the body. They have many health benefits:

Protect cells against oxidative stress
Supports the immune system
Contributes to cardiovascular health
Help prevent certain chronic diseases
Contributes to wellbeing and cellular aging

To better understand how these benefits work on a daily basis and in which foods or beverages polyphenols are most concentrated, let's continue reading the item.

What are polyphenols and why are they essential to health?

Polyphenols are compounds that occur naturally in plant-based foods and beverages. They have multiple roles, and consuming them regularly provides real health benefits and wellbeing every day.

Benefits of polyphenols

Here are the main beneficial effects of polyphenols:

Act as powerful antioxidants, protecting cells from oxidative stress
Supports the immune system
Contribute to the prevention of certain chronic diseases
Promote better cardiovascular health
Contribute to vitality and overall wellbeing

Polyphenol families

Polyphenols are divided into different families, each with its own food sources and benefits:

Polyphenol family	Main sources	Key benefits
Flavonoids	Fruits, vegetables, tea	Protects the heart and blood vessels
Phenolic acids	Coffee, cereal, fruit	Protect cells against oxidative stress
Stilbenes	Red wine	Support cardiovascular health and overall wellbeing
Lignans	Flax seeds, sesame seeds, vegetables	Promotes hormonal and digestive balance

Which drink contains the most polyphenols?

When it comes to the benefits of polyphenols, not all drinks are created equal. Some are particularly focused, others much less so. To give you a better idea, I have compiled some comparative data below:

Beverage	Average polyphenol content (mg per 100 ml)	Key strengths	Limitations
Matcha tea	250–400 mg	Ultra-concentrated in EGCG and catechins, sugar-free and alcohol-free	Requires a good balance
Coffee	200–300 mg	Stimulating, rich in phenolic acids	Excitement, stomach acid
Fruit juice (pomegranate, grape, blueberry)	200–250 mg	Pleasant taste, good flavonoid content	High sugar content
Red wine	100–200 mg	Presence of resveratrol, user-friendliness	Contains alcohol, to be limited
Infused green tea	80–120 mg	Rich in catechins, smooth energy	Less focused than matcha

👉 If I compare these drinks, matcha is the preferred choice as it comes out on top thanks to its exceptional concentration of polyphenols, without any excess sugar or alcohol.

Other dietary sources of polyphenols

In addition to beverages such as tea and coffee, many foods are naturally rich in polyphenols. Including them regularly in your diet allows you to fully enjoy their health and wellbeing benefits.

Here is an overview of the main food sources, ranked according to their polyphenol concentration:

Food	Average polyphenol content (mg per 100 ml)
Dark chocolate (70% cocoa)	150–300 mg
Red berries (blueberries, raspberries, cherries)	50–200 mg
Raisin	50–150 mg
Apples	30–110 mg
Artichoke	30–90 mg
Onion	20–80 mg
Spinach	20–50 mg
Flax seeds / sesame seeds	20–40 mg
Turmeric, rosemary, thyme	10–50 mg

By introducing variants in the ingredients, you can easily increase your daily intake of polyphenols and support your body in a natural and flavoursome way.

Here are some simple tips for getting the most out of polyphenols every day:

Drink 1 matcha bowl every morning to start the day with vitality and energy.
Replace some of the coffee with matcha for more stable and prolonged energy.

Incorporate more coloured vegetables into your meals, such as spinach, red peppers, artichokes, onions, or broccoli...
Choose a square of dark chocolate (minimum 70% cocoa) for a tasty break that's rich in antioxidants.

👉 The important thing is to vary your diet and favor organic and natural products to maximize the health benefits.

Potential risks and precautions to take

Polyphenols are generally safe when consumed through natural foods and beverages, but certain precautions are useful:

Excessive consumption of dietary supplements may cause digestive problems or interfere with certain medications.
People with coagulation problems or taking anticoagulant treatments should remain cautious, particularly with matcha tea or red wine.
Coffee and tea can increase nervous system stimulation if consumed in very large quantities.
Certain foods that are very rich in calcium (cheese, whole milk) or excess minerals can reduce the absorption of polyphenols.
It is recommended to vary the sources of polyphenols to enjoy their effects without overloading the body.

By following these simple tips, you can safely incorporate these antioxidants into your daily routine.

In summary, to fully enjoy the benefits of polyphenols, vary your diet with fruits, vegetables, seeds, dark chocolate, and matcha tea. These simple habits support your body, boost your energy, and bring a real moment of wellbeing to your daily life.
