premature death and oxidation

About Jang Un-kyung and Oxidation

Jang Un-kyung was an Olympic silver medalist who, sadly, passed away in her 50s due to heart disease. Some say this was caused by rapid oxidation in her body.

So, what is oxidation?

Oxidation refers to a chemical process where oxygen combines with other substances, often stealing electrons from them. In the human body, it can be thought of as cells being damaged by oxygen, similar to how iron rusts.

This oxidative process produces free radicals, unstable molecules that damage cells and tissues. Common triggers for oxidation include:

Normal metabolism

Smoking

Air pollution

UV rays

Stress and even excessive exercise

These factors increase the amount of oxidative stress, which is closely linked to aging, heart disease, cancer, and other chronic conditions.

Can Vitamin C Help?

Vitamin C is a powerful antioxidant. This means it helps neutralize free radicals and reduce oxidative stress in the body. It supports cell protection, strengthens the immune system, and promotes healthy blood vessels by aiding collagen production.

However, taking Vitamin C does not "cure" oxidation that's already occurred. Rather, it helps prevent further damage or slow it down.

Best Sources of Vitamin C

Rich in Vitamin C:

Bell peppers (especially red): ~190mg per 100g

Broccoli: ~90mg per 100g

Kiwi: ~90mg per fruit

Citrus fruits (oranges, grapefruits, tangerines)

Strawberries, papaya, mango, and acerola cherries (the most vitamin C-rich fruit)

Lettuce?

Yes, lettuce does contain vitamin C, but in very small amounts — only about 3–10mg per 100g, which is far lower than most fruits or vegetables. While it's healthy in other ways (fiber, folate, vitamin K), it's not a major source of vitamin C.

How to Take Vitamin C Effectively

Eat it raw: cooking can destroy vitamin C

Take it in small amounts throughout the day, as excess is excreted in urine

Liposomal Vitamin C supplements offer higher absorption

Be cautious with high doses if you have kidney issues or sensitive stomach

What Is Oxidation? What Is Reduction?

These two terms go hand in hand:

Oxidation

Losing electrons

Or gaining oxygen / losing hydrogen

Example: iron rusting, aging skin, cellular damage

Reduction

Gaining electrons

Or losing oxygen / gaining hydrogen

Example: antioxidants giving electrons to neutralize harmful molecules

Simple Analogy:

Oxidation = being robbed (electron loss)

Reduction = being rescued (electron gain)

In the Body:

1. Free radicals steal electrons from healthy cells → oxidation

2. Antioxidants (like Vitamin C) give electrons to free radicals → reduction

Vitamin C gets oxidized itself, but it protects other cells through this sacrifice.
