Plant Compounds in Spices: Polyphenols, Antioxidants & Everyday Use

Why do plants make these compounds?

Many of the chemicals humans appreciate in spices did not evolve for us.

Plants use chemical compounds for their own purposes: protection from pests and pathogens, responses to environmental stress, attraction of pollinators and other biological functions.

Those same molecules can produce the aromas, colors, heat and flavors we experience when we cook.

That is one reason spices are chemically interesting: a tiny pinch can contain a remarkably complex mixture of naturally occurring plant substances.

Humans valued spices long before modern chemistry

Our relationship with spices is ancient.

Across cultures, spices have been used to make foods more aromatic, flavorful and distinctive. They became tied to regional cuisines, rituals and traditions. Certain spices became valuable international trade goods and helped shape historical trade routes.

People did not know the words polyphenol, eugenol or curcumin.

They knew that cinnamon smelled extraordinary.

That cloves transformed food.

That ginger brought heat.

That cardamom could change an entire cup of coffee or tea.

That peppers created sensations unlike almost any other food.

Modern chemistry gives names to compounds that humans had already learned to recognize through taste, smell and experience.

Even today, spice mixtures are deeply connected with culture: masala, za’atar, Chinese five-spice, jerk seasoning, berbere, shichimi and countless other blends are examples of how societies combine plant ingredients into recognizable culinary traditions.

⸻

Why were spices so valuable?

Flavor was certainly part of it.

But spices also carried rarity, prestige, cultural meaning and economic value. Their demand helped create trade networks connecting Asia, the Middle East, Africa and Europe.

This history is worth remembering because it shows something very human:

People repeatedly went to extraordinary lengths to obtain plants that could transform ordinary food.

We now have spices in our cupboards that previous generations transported enormous distances to obtain.

⸻

Does drying destroy the plant compounds in spices?

Not necessarily.

Drying changes plant material, but many compounds remain in dried herbs and spices. In fact, measurements expressed by weight can appear especially concentrated after water has been removed.

Research comparing herbs and spices also shows that processing effects vary by the particular plant compound and preparation method.

So “fresh is always better” is too simple.

Fresh and dried forms can have different chemical profiles and different culinary uses.

⸻

Does cooking change them?

Yes — but not in one predictable direction.

Heat may reduce some compounds while making others more available or creating new reaction products. Boiling, baking, frying and dry heating can affect different spices differently.

Researchers studying herbs and spices have found that preparation method, digestion and the food matrix all matter.

That is another reason to avoid sweeping claims such as “cooking destroys antioxidants.”

Food chemistry is more complicated than that.

⸻

Which spices contain polyphenols?

Many common culinary spices contain polyphenols.

Research reviews frequently discuss cloves, cinnamon, turmeric, ginger, cardamom and chili peppers among others. Certain analyses have found particularly high phenolic content or antioxidant activity in cloves and cinnamon.

But there is an important practical consideration:

People do not eat 100 grams of cinnamon or cloves at a meal.

Spices are typically consumed in relatively small amounts. That means laboratory concentration should not be confused with the amount a person actually consumes.

The more useful idea may be variety and regular culinary use, rather than trying to find the single “best” spice.

⸻

An easier question: how can we use more plant ingredients in ordinary food?

This is where spices become especially interesting.

They can fit into things people already eat and drink:

Coffee
Tea
Oatmeal
Yogurt
Fruit
Smoothies
Toast
Pancakes
Baking
Roasted vegetables
Soups and savory dishes

You do not have to redesign your entire diet to use another plant ingredient.

Sometimes it can be as simple as sprinkling cinnamon into oatmeal, ginger into a smoothie, cardamom into coffee or a mixture of spices onto fruit.

That everyday simplicity is what interests us most.

That is also the idea behind Original Fika Spice™⁠, our blend of nine real spices created first for coffee but easy to use in many everyday foods.

If you prefer a touch of natural sweetness, our Maple Sugar Fika Spice™ uses the same spice blend with real Wisconsin maple sugar.

And if you would like to experience both, The Fika Discovery Set™⁠ includes one full-size bottle of each blend.

A different way to think about spices

The question does not have to be:

“Which spice will make me healthier?”

A better question may be:

“How can I make a wider variety of plants easier and more enjoyable to use regularly?”

Spices can contribute flavor, aroma, variety and naturally occurring plant compounds at the same time.

That does not make them medicine.

It makes them fascinating food.

What science knows — and what it does not

Research has clearly established that culinary spices contain many phytochemicals, including polyphenols and other biologically active compounds. Scientists can identify these compounds and measure many of their chemical properties.

What is much harder to determine is exactly how a small culinary amount of a spice affects long-term human health.

Researchers have to account for:

• amount consumed
• frequency of consumption
• differences between people
• digestion and absorption
• interactions with other foods
• cooking and processing
• differences between laboratory, animal and human studies

That is why we prefer curiosity over exaggeration.

Spices are chemically complex plant foods with an extraordinary human history. That is interesting enough without turning every compound into a health promise.

⸻

What about the word “antioxidant”?

You will often see spices described as “high in antioxidants.”

Scientifically, many spices do contain compounds that demonstrate antioxidant activity in laboratory research.

But food-label claims such as “high in antioxidants” have specific FDA requirements when used to characterize the antioxidant nutrient content of a food. FDA rules generally require the identified antioxidant nutrient to have an established daily intake value and meet defined levels.

For that reason, we think the clearest wording is:

Spices naturally contain plant compounds, some of which demonstrate antioxidant activity in research.

That explains the science without suggesting that a culinary serving has been proven to produce a particular medical effect.

Why Fika Spice is interested in this subject

Fika Spice began with a very simple habit: adding spices to coffee.

Our Original Fika Spice™⁠ combines nine plant-based spices into one blend so they are easy to sprinkle into coffee and everyday foods.

We love their flavor.

We love their history.

And we find the chemistry of spices fascinating.

For people who want to explore both of our flavors, The Fika Discovery Set™⁠ brings Original Fika Spice™ and Maple Sugar Fika Spice™ together in one set.

We also offer larger Fika sets designed for sharing, gifting, and making fika part of everyday life. These include The Daily Fika Set™ and our other Fika gift sets, which can be found in our Fika Spice product collection⁠.

We especially like the idea of giving spices as a gift because it allows someone to share more than a product. It can be an invitation to try something new, make a cup of coffee, sit down together and create a little more room for fika.

We also believe people deserve clear information without exaggerated promises.

So as we continue learning about spices, plant compounds and food traditions, we will share what credible research tells us — including what scientists know, what they are still studying and where the evidence has limitations.

Because sometimes the most interesting story isn’t about finding a miracle ingredient.

It’s about rediscovering the remarkable plants that have been sitting in human kitchens for centuries.
