Cooking Influences Cruciferous Vegetables's Antioxidants Capacities

By Kyle J. Norton

Antioxidants are stable atom that plays a critical role in protecting the body against the attack of free radicals.

In other words, antioxidants inhibited the onset of free radical before they can cause a chain reaction in facilitating the protein, lipid and cell damage.

Antioxidants can either produced by the liver or intake from dietary sources. Under normal conditions, antioxidant enzymes produced by the body in a healthy individual are good enough to counter the bombardment of free radical attacks.

However, in people with a weakened immune system, intake dietary sources of antioxidants may be necessary.

On the other hand, free radicals are highly reactive molecules with an unpaired electron on the outer ring of the atom.

Due to its nature to become stable, free radicals readily to donate or steal an electron from other molecules, leading to the chain of domino's effect that can not be stopped until either the electrons are paired or inhibited by antioxidants.

This chain of reaction is the cause of oxidative stress, a condition is associated with either overexpression of free radicals or depletion of antioxidant enzymes produced by the host organs.

Oxidative stress is a condition caused by an imbalance of the ratio of free radicals and antioxidants in the body.

Some researchers suggested that oxidative stress may also arise due to the chain reaction of free radicals in which free radicals donate or intercept an electron from other stable molecules.

Cruciferous vegetables are a group of vegetables, belongings to the family Brassicaceae (also called Cruciferae) with many genera, species, and cultivated all over the world in suitable climate for commercial profits, including cauliflower, cabbage, kale, garden cress, bok choy, broccoli, Brussels sprouts, and green leafy vegetables.

On finding a natural antioxidant whole food, researchers examined the antioxidant activities of some Brassica vegetables.

According to the dietary information,
* The antioxidants in cruciferous vegetables were found to be influenced by antioxidant breakdown and leaching during cooking, particularly in heat cooking.

* Brassica vegetables, including cruciferous vegetables, perceived minor antioxidant ability in processed vegetables compared to uncooked samples.

* Food processing operations in terms of blanching, canning, sterilizing and freezing have a strong effect on the antioxidant capacity.

In other words, cooking methods perhaps can have a major influence on the yield, chemical structure, and bioavailability of antioxidants in the Brassica family.

More precisely, the consumption of raw or slightly blanched veggies is an appropriate way to maximize its health benefits.
