How To Fight Free Radicals With Better Health

As the holidays are fast approaching, many people are deciding what meals they will serve to their families. Although it’s a joyous season, the food we eat and the stress of planning can negatively affect our bodies. So, this is the perfect opportunity to talk about free radicals.

This season and many other times, we indulge in unhealthy food and stress. Free radicals are everywhere, and because of that, fighting against them may seem like an impossible task. But it's not impossible, and with some health tips, you'll be fighting free radicals in no time.

Keep reading to discover how better health practices can combat these pesky molecules and improve your well-being.

What Are Free Radicals?

Free radicals are reactive chemicals created in our bodies when a molecule gains or loses an electron. These chemicals are a natural part of the body's functions and are essential to regular cellular processes. But, in high concentrations, they are harmful to our health. Free radicals can potentially damage all major cell structures, including:

  • DNA
  • Proteins
  • Cell Membranes

Free radical damage leads to a state called oxidative stress. Oxidative stress occurs when free radicals outweigh the balance of antioxidants in your body. Our body produces some free radicals naturally because of metabolism and other natural processes. 

When there are more free radicals than the body can handle, it can't counteract their harmful effects, and damage occurs. Many sources link various health issues to free radical damage like:

  • The Aging Process
  • Heart Disease
  • Cancer
  • Brain Diseases

Learning how to manage free radicals in your body can change the future of your health.

What is Oxidative Stress?

Oxidative stress happens when there's an imbalance between free radicals and our ability to fight them. When free radicals overwhelm our body, they react with our cells, damaging them. To visualize oxidative stress, think of it like a rust that forms on an old bicycle left out in the rain.

Like rust damages metal, oxidative stress is a process that damages our cells. When our defenses are overwhelmed and can't keep up, we can start to "rust" from the inside. Researchers can link oxidative stress to numerous health problems, including:

  • Arthritis
  • Lung Diseases
  • Immune Deficiency
  • Free Radical Theory of Aging
  • Issues With Normal Brain Function

Several factors contribute to increased oxidative stress: environmental pollutants, excessive workouts, unhealthy diet, cigarette smoke, and too much alcohol. Unfortunately, our natural antioxidant defenses decline with age, further complicating the problem. Antioxidants are our best defense to slow down cell damage.

These can naturally occur in our bodies, or we get them through foods and supplements. Certain foods like fruits and vegetables, nuts, whole grains, and lean meats are rich in antioxidants. Regular exercise and maintaining a healthy lifestyle also lower oxidative stress. 

This study provides more in-depth information about oxidative stress and its effects on the body.

How Does Oxidative Stress Affect Us?

Oxidative stress plays a significant role in our bodies, and you shouldn't take it lightly. Imagine a war inside your body, where the noble defenders (antioxidant defenses) fight against the rebellious invaders (free radicals). As the balance shifts in favor of the free radicals, they start causing damage (oxidative stress) to our cells.

So this would be like the bullets causing structural damage to buildings. This damage may appear superficial, but it runs deep. Oxidative stress can reach the DNA of our cells and lead to mutations, impaired function, and even cell death.

The effects of this internal chaos can manifest everywhere. It's a bit like a domino effect—once the balance tips, it can trigger a chain reaction of health issues. It also causes chronic inflammation, our body's natural response to engage the healing process.

Short-term inflammation is okay when our immune system deals with infections or repairs an injury. However, long-term inflammation is a symptom of oxidative stress and a problem.

What Causes Free Radicals in the Body?

We've already mentioned that our bodies form free radicals naturally as by-products of everyday events. Yet, there are many free radical sources that we deal with daily, which can quickly increase their levels in our bodies. These sources include:

  • Highly Processed Foods
  • No Whole Foods in Our Diet
  • Medications
  • Alcohol and Drugs
  • Environmental Pollution
  • High stress

Free radical damage comes from all angles. For example, do you usually use sunscreen when going outside? How often do you eat processed foods?

Do you exercise regularly or sit at a desk all day? Do you experience high levels of stress? Let's discuss these lifestyle choices because they contribute to free radical production.

Processed Foods

If we wanted to box free radicals in food, we would call them processed foods. Unfortunately, they are a significant source of free radicals. They often contain unhealthy fats, sugars, salt, and chemical additives, which can lead to oxidative stress. 

They seem appealing as a convenience but offer little nutritional value and harm our health in the long run.

  • Unhealthy Fats: Processed foods are usually high in trans fats and saturated fats. These types of fats increase levels of harmful LDL cholesterol and decrease beneficial HDL cholesterol. This causes heart disease and stroke.
  • Sugars and Salt: High sugar intake can lead to increased production of free radicals. Too much salt can increase blood pressure and indirectly cause more free radical production. This may lead to salt stress or "salt-sensitive hypertension," which causes more oxidative stress. 
  • Chemical Additives: Many processed foods contain chemical additives like preservatives, artificial colors, and flavor enhancers. These substances can lead to increased production of free radicals.

Instead of processed foods, consider filling your plate with natural, antioxidant-rich foods. Fruits, vegetables, whole grains, and lean meats can provide the nutrients your body needs to combat free radicals. 

Absence of Whole Foods in Your Diet

The absence of whole foods in your diet can significantly contribute to free radicals levels in your body. Whole foods like fruits, vegetables, lean meats, and whole grains are rich in antioxidants that help fight free radicals. These molecules stabilize free radicals by donating an electron, reducing their potential harm.

A diet without these antioxidant powerhouses leaves your body ill-equipped to counteract free radicals. As a result, oxidative stress increases, damaging your cells and potentially triggering a cascade of health problems.

Medications and Antibiotics

Medications are a considerable part of the "Western diet" and impact our bodies' free radical levels. Certain medications and antibiotics can make our bodies produce more free radicals. While these drugs should alleviate health issues, their metabolic breakdown can increase oxidative stress.

Some medications can alter cellular processes, increasing free radical production and decreasing antioxidant defenses. For example, acetaminophen, when taken in large doses, can produce quinone imine, a potent free radical. Many medicines trigger oxidative stress by increasing the production of free radicals.

Medicines like quinolones and aminoglycosides can also form free radicals, causing harm to the cells. This research suggests a correlation between antibiotic usage and elevated oxidative stress levels. While these medications are essential for treating bacterial infections, you should use them sparingly to minimize oxidative stress.


Excessive alcohol is another driving force of free radicals in the body. When broken down in our bodies, alcohol turns into a toxic compound called acetaldehyde. It’s a potent source of free radicals. 

Alcohol can cause a state of hypoxia, or low oxygen levels, in the liver. Hypoxia increases the free radicals and potentially leads to liver disease. Chronic alcohol consumption robs our bodies of glutathione, an antioxidant pivotal in neutralizing free radicals. Decreased glutathione can make your body more susceptible to oxidative stress.


Environmental pollution, from smoggy city air to the chemicals in our homes, is another common source of free radicals. Our air contains vehicle smog, industrial waste, and tobacco smoke. These airborne toxins trigger oxidative stress, leading to health complications.

  • Air Pollution: Prolonged exposure to polluted air can elevate oxidative stress in the body. A study found that living near industrial areas and heavy traffic can increase blood markers of oxidative stress. This happens because people inhale many pollutants that stimulate the over-production of free radicals.
  • Household Chemicals: Common household chemicals, from cleaning products to personal care items, often induce free radical formation. Parabens, phthalates, and triclosan are just a few examples of chemical compounds that can hurt us.

Living in an era of uncontrolled pollution and minimizing our exposure to toxins is difficult. However, simple lifestyle changes can help lower the risk. Try using natural cleaning products, reducing plastic usage, and embracing a more sustainable lifestyle.

High Stress

High stress is a common health issue in modern society that can profoundly affect our bodies. Most people are under constant pressure to perform at work, maintain relationships, and handle daily responsibilities. This state of endless stress can lead to elevated cortisol levels, a hormone produced in response to stress.

High-stress levels can promote free radicals in your body, increasing oxidative stress risk. When you're feeling stressed, your body releases stress hormones. Stress can boost free radicals and reduce antioxidant effects. 

Studies show that chronic psychological stress causes damage, indicating a vital link between stress and free radical production. Reducing stress should be the ultimate goal. Including stress-reducing activities in your routine can make a difference. 

Removing these stressors is nearly impossible, though. Taking stress from our lives entirely is also not a viable solution. Instead, we can adopt better health practices and make small changes in our lifestyle.

How Do You Fight Free Radicals With Health and Wellness?

There are many ways to fight free radicals and reduce oxidative stress. Making lifestyle changes and choosing healthy practices can help keep free radicals at bay. Let’s discuss how to fight free radicals with better health and wellness.

Antioxidant-Rich Diet

An effective way to combat free radicals is by adopting an antioxidant-rich diet. Antioxidants, also called "free radical scavengers," help neutralize these unstable molecules, stopping them from causing cellular damage. Foods that fight free radicals include fruits, vegetables, nuts, whole grains, and seafood.

According to a study, eating a high-antioxidant diet can help ward off oxidative stress.

  • Fruits and Vegetables: Try eating fruits like berries, oranges, and pomegranates. Then, eat vegetables like spinach, kale, and bell peppers with loads of potent antioxidants like vitamins A, C, and E.
  • Nuts: Almonds, walnuts, and other nuts are high in vitamin E, which protects our cells from damage.
  • Whole Grains: Brown rice, oatmeal, and whole wheat bread are rich in antioxidants, including selenium and zinc.
  • Dark Chocolate:  Yes, dark chocolate is also an excellent source of antioxidants. It contains flavonoids, potent antioxidants that can help reduce oxidative stress.
  • Seafood: Certain types of seafood, including salmon and mackerel, contain high omega-3 fatty acids. Omega-3s have antioxidant properties.

Remember to maintain a balanced diet to fight free radicals. Some antioxidant supplements and dietary supplements also contain these compounds. Still, it's always best to consult with your healthcare professional before adding supplements to your diet.

Regular exercise, adequate sleep, and stress reduction are critical to maintaining a healthy, free-radical-fighting lifestyle.

Exercise Regularly

Regular physical exercise benefits overall health and plays a significant role in combatting free radicals. Engaging in various exercises, from aerobic workouts to strength training, can stimulate the body's antioxidant defenses. According to a study, regular exercise can increase the production of natural antioxidants, protecting cells from free radical damage.

  • Aerobic Exercises: Activities like running, swimming, or cycling increase your heart rate and get your blood pumping. This action boosts your body's natural antioxidant production.
  • Strength Training: Weightlifting and resistance training can promote antioxidant defense by improving muscle strength and overall body composition.
  • Yoga and Meditation: These slow, mindful exercises may not seem as physically demanding, but they're great for reducing stress. 

However, it's important to remember that balance is necessary. While regular exercise can help fight against free radicals, excessive and intense workouts can have the opposite effect. 

Limiting UV Exposure

Extended exposure to ultraviolet (UV) rays produces free radicals, leading to oxidative stress. UV rays can damage the skin, cause premature aging, and increase the risk of skin cancer. Excessive sun exposure makes sun protection pivotal for anyone fighting free radicals and maintaining healthy skin.

  • Use Sunscreen: A broad-spectrum sunscreen that blocks UVA and UVB rays is a must, regardless of the weather. Choose sunscreen with an SPF of 30 and use it every two hours.
  • Wear Protective Clothing: Long-sleeved shirts, long pants, and wide-brimmed hats can provide added protection against the sun's harmful rays.
  • Seek Shade: Try to stay in the shade, especially during the sun's peak hours from 10 a.m. to 4 p.m.
  • Wear Sunglasses: Protect your eyes by wearing sunglasses that block 100% of the sun's UV rays.

Despite the dangers of too much UV exposure, some sun exposure is necessary. Our bodies can't produce Vitamin D, but sunlight helps our bodies produce it. But again, moderation is key.

Sun exposure equal to 15-30 minutes per day should be enough for most people to produce the required vitamin D.

Less Stress

Stress can be devastating and force our body to produce free radicals. Chronic stress increases oxidative stress, leading to various health issues. On the other hand, happiness and positive emotions have lower oxidative stress levels and better health.

Here are a few suggestions for stress relief:

  • Mindfulness and Meditation: Practicing mindfulness and meditation can help reduce stress levels. Mindfulness-based stress reduction can decrease cortisol levels and reduce oxidative stress.
  • Adequate Sleep: Ensuring sufficient sleep is another way to manage stress. Studies show that lack of sleep disrupts cortisol regulation, which can lead to increased stress and free radical production. If you’re having trouble sleeping, try supplementing melatonin.
  • Social Connections: Maintaining strong social connections can also help alleviate stress. Positive social interactions can trigger the release of oxytocin, which counteracts the stress hormone cortisol.

It's unlikely that stress will ever go away completely. We can manage it through healthy coping mechanisms that reduce free radicals in our bodies.

Drink Alkaline Water and Stay Hydrated

Drinking alkaline water and staying hydrated is crucial in maintaining overall health and combatting free radicals. Alkaline water has a higher pH level than tap water and can neutralize the acid in your body. It also contains a higher proportion of hydrogen, thus potentially reducing the amount of free radicals.

Research shows alkaline water can detoxify the body, balance pH levels, and improve hydration better than regular water.

  • Alkaline Water: Drinking alkaline water may help fight the harmful effects of free radicals, boost energy levels, and improve digestion. Other potential benefits include reducing acid reflux, lowering high blood pressure, and helping with weight loss.
  • Regular Hydration: Drink eight or more glasses of water daily to maintain proper body functions and hydration. Water helps flush out toxins and free radicals from your body. It also aids digestion, improves skin health, and supports nutrient absorption.
  • Hydrogen Water: Hydrogen water, simply put, is water infused with hydrogen gas. Various sources suggest that this seemingly simple addition enhances the water's anti-inflammatory and antioxidant properties.

Stay adequately hydrated, and occasionally substitute your regular water with alkaline water.

Final Thoughts

In the quest for better health, people often overlook combating free radicals. But remember, it's not all about grand gestures. Sometimes, the simplest changes do the most good. Include mindful strategies like:
