What is oxidative stress? How does it affect our bodies?

We all want to live healthy and disease-free lives. But sometimes, without us realizing it, a big battle is going on inside our bodies. As a result of this battle, many serious diseases like diabetes, high blood pressure, heart disease, and cancer are opened. That is the silent enemy that we are talking about in this article today. In medicine, we call this condition oxidative stress .

Simply put, what is oxidative stress?

To understand this, we first need to know about two main characters in our body.

1. Free Radicals: Think of these guys as little bad guys in our bodies. They are created during normal processes in our bodies, such as when we turn the food we eat into energy, or when we are exposed to environmental pollutants. Because they are unstable, they tend to damage healthy cells in our bodies and disrupt their function. Just like iron rusts, these free radicals try to "rust" our cells.

2. Antioxidants: These are the body's defense mechanisms. They're like superheroes protecting our cells from the bad guys. These antioxidants neutralize free radicals and prevent them from damaging our cells.

So, oxidative stress is the imbalance between these rogues (free radicals) and the defenders (antioxidants). When the number of rogues increases and there are not enough defenders to control them, our body's cells, DNA, and tissues begin to be damaged. This long-term damage is the root cause of many diseases.

Although some studies have found that this oxidative stress can help fight things like cancer cells, it is generally the harmful side that is most often seen.

The importance of antioxidants and how to get them?

Antioxidants, our body's defense mechanisms, are very important to us. They protect our cells, helping to prevent or reduce the effects of heart disease, cancer, and many other non-communicable diseases.

The best thing is that we can get these valuable antioxidants naturally from food.

  • Vitamins C and E: Found abundantly in oranges, grapefruit, guava, papaya, avocado, vegetable oils, and nuts.
  • Carotenoids: Found in dark-colored fruits and vegetables like carrots, sweet potatoes, pumpkins, and tomatoes.
  • Flavonoids and Tannins: Found in tea, coffee, cocoa, dark chocolate, and berries.
  • Our spices: turmeric, cinnamon, and cloves are also excellent sources of antioxidants.

That means eating a colorful, balanced diet is one of the best ways to combat oxidative stress.

Diseases that can be caused by oxidative stress

Free radicals continuously damage our cells, which can lead to a number of serious diseases over time. Let's take a look at those diseases and how oxidative stress affects them in the table below.

Condition How Oxidative Stress Affects It
Hypertension Oxidative stress damages the walls of blood vessels, causing them to lose their elasticity and become stiff, which increases blood pressure.
Atherosclerosis Bad cholesterol (LDL) in the body is oxidized by free radicals and begins to deposit on the walls of blood vessels. These are called "plaques". This causes the arteries to narrow, increasing the risk of heart attack and stroke.
Heart disease and heart failure When antioxidant levels decrease, heart muscle cells can be damaged. This can weaken the heart's function and, over time, lead to a condition called heart failure.
Stroke Oxidative stress damages brain cells. Especially if a stroke occurs, brain damage can be more severe in someone with low antioxidant levels.
Cancer Oxidative stress can damage the DNA in our cells. This DNA damage causes cells to divide uncontrollably. This is the beginning of cancer.
Diabetes Oxidative stress can reduce the body's response to insulin (insulin resistance) and can also damage the insulin-producing cells in the pancreas. Both of these are major causes of diabetes.
Neurological Diseases Damage to brain cells (neurons) increases the risk of conditions such as memory loss, Alzheimer's disease , and Parkinson's disease .

So is it okay to take antioxidant pills?

This is a question that many people ask. Oxidative stress is a very complex process. Therefore, just taking antioxidant pills (supplements) will not completely solve this problem. The best thing is to adopt a healthy lifestyle .

  • A good diet: A diet rich in fruits, vegetables, nuts, legumes, and spices.
  • Exercising regularly.
  • Avoiding smoking and alcohol.
  • Controlling stress.
  • Getting enough sleep.

All of these help reduce oxidative stress. It is important to talk to your doctor about your health, especially if you have risk factors such as diabetes or high blood pressure. Never take additional vitamins or antioxidant supplements without medical advice.

Take-Home Message

  • Oxidative stress is the imbalance between free radicals and antioxidants in our body.
  • This condition is like our cells "eating rust." It damages cells, DNA, and tissues.
  • This can be a root cause of many serious diseases such as diabetes, heart disease, high blood pressure, cancer, and neurological diseases.
  • We can get the antioxidants we need through a diet rich in colorful fruits, vegetables, legumes, nuts, and spices.
  • A healthy lifestyle (good diet, exercise, stress management) is the best defense against oxidative stress.
  • Always consult your doctor before making any decisions about your health condition or taking vitamin supplements.
