    Deep Nutrition: “If You Want Antioxidants, Skip the Latest Products and Buy Fresh Foods”

    The truth is, you’ll get a better blend of antioxidants simply by eating a variety of familiar greens, along with fresh herbs and spice

    In a world of ever-evolving “superfoods,” it’s easy to think the next magical powder holds the key to perfect health.

    But when it comes to antioxidants—the chemical defenders that help keep our bodies healthy—the truth is refreshingly simple:

    Skip the supplement and go for fruits and vegetables.

    How and what should you eat to get antioxidants?

    If you are in a hurry, scroll to the end for our Action Takeaways.


    🌾 1. What Are Antioxidants and Why Do We Want Them?

    Antioxidants are your body’s internal bodyguards, protecting your cells from damage caused by unstable molecules called free radicals.

    Free radicals are a natural byproduct of metabolism. But they can cause problems when their levels get too high—leading to oxidative stress, which plays a role in aging, inflammation, and chronic diseases like cancer and heart disease.

    Two key harmful effects antioxidants help fight:

    • Lipid oxidation – when fats in your body go rancid, damaging cells.
    • Advanced glycation end-products (AGEs) – compounds formed when sugar binds to proteins or fats, contributing to aging and inflammation.

    Antioxidants “throw themselves in the line of fire,” neutralizing these harmful effects.

    That’s why a diet rich in antioxidants is considered one of the best long-term investments for your health.


    ❌ 2. The Problem with Antioxidant Supplements

    Walk into any health store, and you’ll see shelves lined with antioxidant supplements: goji, ginseng, acai powder…

    But here’s the thing:

    Most of these are marketing more than magic.

    While these products promise concentrated antioxidant power, what they don’t tell you is:

    • They’re often made from the same fruits and vegetables you find in the produce section.
    • Processing (drying, heating, bottling) degrades antioxidant potency.
    • Supplements may lack the complex balance of nutrients found in whole foods.
    • Some concentrated antioxidants in pill form can have side effects or disrupt your body’s natural balance.

    Instead of reaching for capsules, reach for something alive, colorful, and edible.


    🍎 3. Where to Get Antioxidants Naturally

    You don’t need magical supplements to get your antioxidants. Here’s how to get antioxidants naturally:

    • Fresh greens like spinach, arugula, and lettuce
    • Herbs and spices like basil, thyme, garlic, and dill
    • Pungent veggies like broccoli, celery, and peppers
    • Fresh fruits like berries, apples, and grapes

    Whole foods contain a variety of antioxidantsflavonoids, terpenes, coumarins, retinoids, and more—all working together.

    Why do plants contain antioxidants?

    Plants make these compounds to protect themselves from oxygen damage. When we eat them fresh, we consume these antioxidants too.

    Here’s a quick and easy way to get antioxidants:

    Grow some herbs on your balcony. Cheap, tasty, and full of potent nutrition.


    🔥 4. Go for Flavor—It’s a Clue

    How do you know which plant is rich in antioxidants?

    You can taste it.

    Plants that are highly nutritious tend to have an intense flavor.

    Bitter, spicy, or pungent vegetables (like arugula, garlic, peppers) have higher concentrations of antioxidants and phytonutrients.

    In contrast, bland or starchy vegetables (like potatoes or turnips) tend to be lower in antioxidants per bite.

    If it lights up your tongue, it’s most likely high in antioxidants.


    🧂 5. How to Eat Veggies for Antioxidants—Raw or Cooked?

    On one hand, fresh, raw vegetables preserve delicate antioxidants and vitamins that can be destroyed by heat.

    On the other hand, many nutrients in plants are locked inside cellulose — the fibrous material that makes plants crisp and firm.

    Our digestive systems often struggle to break down cellulose, and cooking vegetables helps break down their cellulose walls.

    So should we eat veggies raw or cooked?

    Raw v.s. Cooked Veggies

    Here’s the balanced truth:

    🌱 Raw is Best For:

    • Leafy greens (spinach, lettuce, arugula)
    • Herbs (parsley, cilantro, basil)
    • Tender fruits and vegetables (berries, peppers, cucumbers)

    Raw foods preserve delicate antioxidants and water-soluble vitamins that cooking might destroy.

    🍽️ Cooked is Better For:

    • Dense or high-cellulose veggies (carrots, broccoli, mushrooms)
    • Foods with hard-to-access nutrients (like beta-carotene in carrots)

    Cooking breaks down cellulose and increases bioavailability.

    For instance, only 1% of vitamin A precursors in raw carrots are absorbed—but cooking raises that to 30%!

    The ideal strategy?

    Eat a mix of raw AND cooked vegetables

    For example:

    • Add raw veggies and herbs to salads and sandwiches
    • Cook dense veggies gently—steam, fry, or microwave them at moderate heat.
    • Pair cooked meals with something fresh to balance it out.

    Freshness always matters—whether raw or cooked.

    The longer food sits after harvest, the more nutrients it loses. Local, in-season produce is the best option.


    Actionable Takeaways

    1. Choose fresh, whole foods over supplements
    2. Eat a variety of raw and lightly cooked plants
      • Eat raw herbs, salad leaves for natural antioxidants.
      • Cook dense or high-cellulose veggies (like carrots, broccoli) gently to make their nutrients more absorbable.
    3. Buy local and eat seasonal when possible. Fresher produce = more antioxidants and better taste.

  • Deep Nutrition: 3 day of sprouting makes seeds/legumes more nutritious

    Deep Nutrition: 3 day of sprouting makes seeds/legumes more nutritious

    What is sprouting?

    Sprouting is the process of germinating seeds—starting their growth by soaking them in water for a few days until they begin to sprout tiny rootlets.

    This natural process activates enzymes inside the seed, beginning the transition from a dormant state to a living plant.


    What can we sprout?

    You can sprout any kind of seed, for example:

    • Wheat berries (the seeds of wheat)
    • Kidney beans
    • Mung beans
    • Chickpeas
    • Lentils

    Other seeds and legumes could work too.

    Generally speaking, if it’s a whole seed, you can sprout it.

    Photo by livingsmartandhealthy.com

    Personally I’ve sprouted soybeans, black beans, green peas, chickpeas, and linseeds. They all sprouted well, and tasted delicious too!

    The process takes 2-4 days.

    Here are green pea sprouts after 3 days of sprouting:


    What are the benefits of sprouting?

    Sprouting has multiple nutritional benefits:

    • Stored starch and fatty acids are converted into proteins and vitamins.
    • Sprouting activates enzymes, like phytase, which breaks down phytates (compounds that block nutrient absorption).
    • The process softens the seed, making it easier to grind and digest.
    • Compared to flour from unsprouted seeds, sprouted grain products are less allergenic and more nutrient-dense.

    In summary, sprouting significantly increases seeds and legumes’ nutrient availability and digestibility.

    Our body can more easily absorb the nutrients in seeds and legumes after they are sprouted.


    The Science of Sprouting

    Seeds are built to store nutrients securely, locking them in with chemical binders and a tough outer shell.

    When we soak seeds, moisture triggers germination, which activates the seed’s own enzymes.

    Soaking green peas

    One important enzyme, phytase, breaks down phytates, which otherwise bind up minerals like iron, zinc, and calcium.

    This enzymatic activity:

    • Softens the seed (physically)
    • Unlocks nutrients (chemically)
    • Transforms starches and fats into proteins and vitamins (biochemically)

    It’s like nature’s own little nutrient boost machine—just add water and time.

    “Moistening the seeds for a few days activates the plant’s own enzymes—including phytase, which digests phytates—to soften the seed, free up bound nutrients, and even create new ones by converting stored starch and fatty acids into proteins and vitamins.”

    From Deep Nutrition by Catherine Shanahan


    How to Sprout at Home?

    1. Choose Your Seeds – Use whole seeds like wheat berries, lentils, kidney beans, or chickpeas.
    2. Soak – Place seeds in a jar and cover them with water. Let them soak overnight or up to 12 hours.
    3. Drain and Rinse – Drain the water and rinse the seeds thoroughly. Cover the jar with a breathable, bug-proof cloth.
    4. Repeat Daily – Rinse and drain the seeds once or twice a day. Keep the jar in a cool, dark place.
    5. Watch for Sprouts – In 1–4 days, you’ll see tiny white rootlets—your seeds have sprouted and are ready to use!
    Sprouting at home

    How Long Does It Take to Sprout Legumes (green peas, chick peas)?

    • Soak Time: 8–12 hours in clean water
    • Sprouting Time: 2–4 days to see visible sprouting (tiny white rootlets)
    • Ideal Consumption Window: Day 2–4

    By day 2, they’re crunchy, slightly sweet, and safe to eat raw or cooked.

    By day 3 or 4, they’ve reached peak digestibility and nutritional value for most people.

    By day 5–6, they start to green up and become more “shoot-like” in flavour and texture.

    The texture gets grassier, and nutrient profile begins shifting more toward leafy greens.


    Nutritional Changes Over 7 Days of Sprouting

    Here’s a general outline of key nutritonal changes during sprouting:

    StageWhat’s Happening Nutritionally
    Day 0–1
    (Soaking)
    Soaking activates enzymes and starts water absorption.
    Day 2–3
    (Sprouting Begins)
    Big drop in phytates (anti-nutrients), freeing up iron, zinc, calcium.

    Digestibility improves.
    Day 3–4
    (Peak Sprout)
    Vitamins C, B-complex, A, and antioxidants content rises. Some starch is converted into simpler sugars for energy.
    Day 5–6+
    (Greening)
    Chlorophyll starts forming as green shoots appear. More fiber, and antioxidants
    OverallEasier to digest, and higher bioavailability of nutrients

    🍽️ Bonus Tip

    Sprouted green peas are super tasty—crunchy with a mild sweetness. Great in:

    • Stir-fries (lightly sautéed)
    • Fresh salads
    • Grain bowls
    • Blended into dips (like a sprouted pea hummus!)

  • Deep Nutrition: Why Fermented Foods Are Better Than Fresh

    Deep Nutrition: Why Fermented Foods Are Better Than Fresh

    Ever wondered why fermented foods like kimchi, yogurt, and sourdough are good for you?

    It’s not just the flavor.

    Fermentation actually adds nutrition to their raw ingredients.


    What is fermentation?

    Fermentation is a biological process involving microorganisms—primarily bacteria and fungi.

    These microbes turn raw, indigestible ingredients into more nutritious, digestible foods for humans.

    For example, sourdough bread, kimchi, yogurt, and kombucha, are all finished products of fermentation.

    The process of fermentation can enhance the foods’ nutritional value.


    How does fermentation make food more nutritious?

    1. Microbes break Down Anti-Nutrients in Plants

    Certain plant-based foods such as seeds and grains contain anti-nutrients.

    Anti-nutrients are plants’ evolved defense mechanism against predators such as insects and other creatures.

    An example of such anti-nutrient is phytates.

    Phytates in seeds, grains, and legumes can block mineral absorption.

    When we eat raw nuts or unleavened bread, these phytates prevent our bodies from absorbing key minerals like zinc, calcium, and magnesium in them.

    This can lead to deficiencies, especially in children.


    However, fermentation activates enzymes that break down phytates, unlocking these essential nutrients.

    An example is fermented bread – sourdough.

    The yeast and microbes in sourdough contain phytase enzymes, which break down phytates during fermentation. This releases the minerals in the bread, making them available for absorption.


    2. Microbes Detoxify Harmful Compounds in Plants

    Some raw foods like soybeans, contain compounds that can disrupt our health.

    Two examples are goitrogens and phytoestrogens in soybeans.

    • Goitrogens – Interfere with thyroid function.
    • Phytoestrogens – Disrupt reproductive hormones, especially risky for infants and pregnant women.

    Traditionally, Asian cultures would soak, rinse, and ferment soybeans to neutralize these harmful compounds.

    This turn soybeans into miso, natto, tempeh, and tofu which are incredibly nutritious.

    However, modern, mass-produced soy milk and soy-based infant formulas are not.

    Many modern soy products—like commercial soy milk and soy-based infant formulas—still contain these harmful compounds.


    Are there living bacteria when we eat fermented foods?

    When we eat foods with living cultures (such as yogurt, pickles, and sauerkraut), our digestive system kills many of these microbes.

    Some fermented foods, like aged cheese and wine, no longer contain live bacteria, while others, like yogurt and sauerkraut, do.

    Regardless, fermented foods still retain higher levels of nutrients than the unfermented ingredients.

    This is because the fermented foods have been enriched by the microbes once lived inside.

    For examples, wine has more antioxidants than grape juice, cheese contain more protein than milk.

    In fact, microbes are like mini vitamin factories.

    They can produce:

    • Essential vitamins (e.g., Vitamin K2, B12)
    • Amino acids (building blocks of protein)
    • Antioxidants (which fight cell damage)
    • Enzymes (which aid digestion)

    Even if some fermented foods no longer contain live bacteria, they still offer enhanced nutrition.

    So, how can you add more fermented foods to your diet?


    How can I ferment at home?

    If you’re new to fermentation, there’s no need to be intimidated. Many fermented foods are widely available, and you can even make them at home!

    Homemade sauerkraut is a great place to start:

    1. Shred a cabbage and mix it with a teaspoon of salt.
    2. Pack it into a jar, ensuring the cabbage stays submerged in its juices.
    3. Cover with a cloth and
    4. Leave it at room temperature for about a week.
    5. Enjoy your homemade probiotic powerhouse!

    Fermenting at home is simple and rewarding. Making sauerkraut, for instance, requires just cabbage and salt.

    With minimal effort, you can create delicious, nutrient-rich fermented foods.

    About the Author

    Andreas Michalsen, MD, PhD, is a German physician and researcher specializing in naturopathy and integrative medicine.

    He is a professor of clinical naturopathy at Charité University Hospital in Berlin and the chief physician at the Immanuel Hospital, which focuses on natural healing approaches. His work integrates modern scientific research with traditional natural medicine practices, such as fasting, plant-based nutrition, and mind-body therapies.


    Chapter 1: The Basic Principles of Naturopathy

    Key Ideas

    • The stimulus-response principle: Health is boosted through natural stimuli like cold therapy, fasting, or hydrotherapy.
    • Unlike conventional medicine, which eliminates disease from the outside, naturopathy activates the body’s self-healing ability.
    • The concept of hormesis: Small amounts of stressors (heat, cold, fasting) strengthen the body.

    Actionable Takeaways:

    • Use small stressors (cold water, heat therapy, fasting) to build resilience.
    • Sunlight in moderation boosts vitamin D and protects against diseases.

    “Naturopathy does not fight illness—it strengthens the body to fight illness itself.”


    Chapter 2: Therapies of Antiquity Rediscovered

    Key Ideas

    • Leeches, cupping, and bloodletting are some of the oldest known naturopathic therapies and were used in ancient Babylon, Egypt, India, and China.
    • Cupping can improve circulation and pain relief, especially for muscle and nerve conditions.
    • Bloodletting (or blood donation) can be beneficial for high blood pressure and iron overload.

    Chapter 3: Hydrotherapy

    Key Ideas

    • Hydrotherapy (water-based treatments) has been used for centuries to boost immunity, improve circulation, and reduce stress.
    • Cold water exposure triggers a hormetic response, strengthening the body’s ability to adapt to stress.
    • Research on public bathhouses in Japan revealed that hot water exposure improves vascular health and stress levels.

    Actionable Takeaways

    • Alternating hot and cold water (e.g., showers, baths, compresses) boosts circulation and immunity.
    • Daily cold exposure (e.g., cold showers or Kneipp foot baths) can increase resilience and reduce inflammation.

    “A cold bath in the morning is like coffee for the circulatory system—it wakes you up and strengthens the body.”


    Chapter 4: Fasting

    Key Ideas

    • Fasting activates the body’s self-healing process
    • Autophagy, a process where cells recycle damaged components, is triggered by fasting.
    • Intermittent fasting (16:8 method) may be more beneficial than constant calorie restriction.
    • Fasting improves hormonal balance, reducing insulin, T3 (thyroid hormone), and IGF-1
    • Fasting reduces inflammation at the molecular level—each meal triggers a minor inflammatory response, while fasting halts this process.

    Actionable Takeaways

    • Try intermittent fasting (16:8 method)—fast for 16 hours, eat within an 8-hour window.
    • Gradually break a fast with light foods like broth, fruits, or steamed vegetables—not heavy meals.

    “Not eating is the most powerful intervention for many diseases—more effective than any pill.”


    Chapter 5: Food as Medicine

    Key Ideas

    • 50-70% of chronic diseases are linked to poor nutrition, yet medicine largely ignores dietary therapy.
    • Ultra-processed foods, sugar, and animal fats are the primary culprits in modern disease.
    • Blue Zones research shows that long-living populations (e.g. in Okinawa and Sardinia) consume plant-based diets with minimal meat
    • Insulin spikes from refined carbohydrates lead to hunger cycles and fat accumulation.

    Actionable Takeaways

    • Minimize ultra-processed foods—eat whole, unprocessed meals.
    • Limit to 2 meals per day—reduce insulin spikes and metabolic stress.
    • Follow a Blue Zones-inspired diet—focus on vegetables, nuts, seeds, legumes, and whole grains.
    • Limit animal protein consumption—especially processed meats and dairy.

    “The healthiest populations in the world don’t obsess over macronutrients—they eat real food.”


    Chapter 6: Stagnation is Cause for Illness – The Importance of Exercise

    Key Ideas

    • Physical activity is one of the most powerful healing tools, reducing the risk of cardiovascular diseases, depression, and cancer.
    • Regular movement strengthens bones, muscles, immune function, and mental health.
    • Studies have shown that people who make long visits to green spaces have lower rates of depression and high blood pressure.

    Actionable Takeaways

    • Exercise doesn’t have to be intense—daily walking, stretching, and resistance training is enough.
    • Use every opportunity you get to walk a few steps.
    • Nature exposure enhances mental and physical health, reducing depression and blood pressure.
    • Avoid prolonged sitting—even light activity throughout the day improves metabolic health.

    “Every step counts—small daily movements add up to significant health benefits.”
