Overview of Oxidative Stress

In understanding the deep and critical role antioxidants play in supporting heart health, it is essential to first delve into the concept of oxidative stress.

Definition of oxidative stress

Oxidative stress is a physiological condition characterized by an imbalance between the production of free radicals and the ability of the body to counteract or detoxify their harmful effects through neutralization by antioxidants. These free radicals are compounds known for their high reactivity due to the presence of an unpaired electron.

Causes of oxidative stress

Oxidative stress can result from various factors such as exposure to environmental pollutants, overconsumption of processed foods, excess alcohol, smoking, and even excessive exercise. If your body cannot effectively detoxify these radicals or prevent their production, oxidative stress can occur, leading to potential damage to cells and tissues.

Effects of oxidative stress on the heart

Research shows oxidative stress is heavily linked with cardiovascular diseases. It can lead to various adverse effects on the heart, such as inflammation and the buildup of low-density lipoprotein (LDL) cholesterol, often referred to as “bad cholesterol.” Over time, these effects can lead to heart disease, including heart attacks and strokes.

Introduction to Antioxidants

The battle against oxidative stress brings us to the protective role of antioxidants.

Definition of antioxidants

Antioxidants are molecules that inhibit the oxidation of other molecules in our body. They work by neutralizing free radicals, thereby preventing these highly reactive substances from causing damage to cells.

Role of antioxidants in the body

The role of antioxidants in the body is vast and vital. They protect our cells against the effects of free radicals, reduce inflammation, slow down the aging process, and work to prevent diseases, including heart disease and cancer.

Sources of antioxidants in the diet

It’s crucial to note that our bodies can produce some antioxidants, but the key to reducing oxidative stress lies significantly in our diets. Foods high in vitamins C and E, beta-carotene, and selenium are powerful sources of antioxidants. These can be found in many fruits, vegetables, nuts, seeds, and even some types of meat and seafood.

The Mediterranean Diet

Among the various diets known for their high antioxidant content, the Mediterranean diet stands out.
