How Exactly Do Antioxidants Benefit Us?

Before we reveal what are these antioxidant foods, let us first dissect how exactly antioxidants benefit us. Antioxidant sources prevent damage caused by free radicals, otherwise known as oxidative stress.

This oxidative stress commonly leads to various diseases.

Some of the major health problems that confront us today like dementia, cancer, and heart disease, have been associated with high levels of oxidative stress and inflammation.

Antioxidants work to combat these damages, which are often caused by poor eating habits, harmful sun exposure, smoking, certain medications, and even chronic stress.

While fighting free radical damage, antioxidants also guard healthy cells and prevent the growth of cancerous or malignant cells.

One of the best ways to measure the antioxidant content of foods is through the ferric reducing ability of plasma (FRAP) analysis.

The FRAP test analyzes how well the foods can neutralize a certain free radical. Foods that have a higher FRAP value contain more antioxidants.
