Antioxidants in Food List
Now Playing: In Search of the Highest Food Antioxidant
1. Antioxidant List2. Largest Antioxidant in Food StudyHerbs Rich Source of Healthy Antioxidants; Oregano Ranks Highest
Better health may be only a dash and sprinkle away: Researchers with the U.S. Department of Agriculture have found that herbs, in addition to making food tastier, are an abundant source of antioxidants and could provide potential anticancer benefits when supplementing a balanced diet.
Herbs have higher antioxidant activity than fruits, vegetables and some spices, including garlic, the researchers say. Some herbs should be considered as regular vegetables. People should use more herbs for flavoring instead of salt and artificial chemicals.
In what may be good news for pizza lovers and Italian food connoisseurs everywhere, the herbs with the highest antioxidant activity belonged to the oregano family. In general, oregano had 3 to 20 times higher antioxidant activity than the other herbs studied.
On a per gram fresh weight basis, oregano and other herbs ranked even higher in antioxidant activity than fruits and vegetables, which are known to be high in antioxidants. In comparison to the antioxidant activities of a few select fruits and vegetables, the potency of oregano ranks supreme: Oregano has 42 times more antioxidant activity than apples, 30 times more than potatoes, 12 times more than oranges and 4 times more than blueberries.
For example, one tablespoon of fresh oregano contains the same antioxidant activity as one medium-sized apple, she says.
Adding a moderate amount of herbs may go a long way toward boosting the health value of a meal, especially as an alternative to salt and artificial additives.
Even if you're not into oregano, other herbs also appear to pack a significant antioxidant punch. Among the more familiar, ranked in order, are dill, garden thyme, rosemary and peppermint.
The most active phenol component in some of the herbs with the highest antioxidant activity, particularly oregano, was rosmarinic acid, a strong antioxidant.
Antioxidants have become synonymous with good health. They are a class of compounds thought to prevent certain types of chemical damage caused by an excess of free radicals, charged molecules that are generated by a variety of sources including pesticides, smoking and exhaust fumes. Destroying free radicals may help fight cancer, heart disease and stroke, researchers believe.
Fruits and vegetables have long been viewed as a rich source of antioxidant compounds. Health officials have been urging consumers for years to eat more fruits and vegetables in order to gain the health benefits of antioxidants, but progress has been slow, according to researchers.
More recently, researchers have begun to formally study the health benefits of herbs and spices. The two differ mainly by source. Herbs typically come from the leaves of plants. Spices come from the bark, stem and seeds of plants. Both have been used for thousands of years to flavor foods and treat illness.
Now, herbs have emerged as a quick and easy way to get a concentrated source of antioxidants - without all the extra calories of whole foods.
Herbs can be consumed in a variety of ways. Some people prefer to drink herb extracts, which can be made by adding herbs to hot water to make potent antioxidant teas. Others use concentrated herbal oils available in some health food stories. Most of us prefer a little dash and sprinkle of the familiar leafy or powdered versions to add flavor to our favorite meats and vegetables.
In general, fresh herbs and spices are healthier and contain higher antioxidant levels compared to their processed counterparts. For example, the antioxidant activity of fresh garlic is 1.5 times higher than dry garlic powder.
Just as consuming too much of any food product can carry health risks, herbs should be used with moderation.
Whatever form they take, herbs are no substitute for a balanced diet. Pregnant women in particular should consult their physicians before taking herbal supplements.

Dr. Mercola's Comment:
Well, now we know the difference between an herb and a spice.
Amazing how two of the most popular Italian herbs, garlic and oregano are two of the most useful nutritional herbs.
If you are not using these two useful herbs I strongly encourage you to consider using them. Remember that most of the major anti-infection benefits of garlic are lost unless you use it raw.
You can use 1-2 cloves in your vegetable juice to obtain maximum benefit. The chlorophyll in the juice also tends to cut down on the potentially offensive garlic odor.

1. Defends Against Free Radicals*
The xanthone flavonoids and other compounds in mangosteen fruit are responsible for its high level of antioxidant activity. In vitro tests have been conducted on XanoMax mangosteen 10% extract to determine the level of free radical scavenging ability in both watery and fatty environments. A major test recognized as the industry standard for measuring antioxidant activity is known as the ORAC (Oxygen Radical Absorbance Capacity) assay.
The ORAC test is an in vitro assay that works by measuring the amount of free radical damage done to a fluorescent probe (measured by a change in probe intensity). Antioxidants lessen the damage to the probe fluorescence, which indicates a reduction in free radical damage. This measure is used to quantify the antioxidant's (or combination of antioxidants) capacity to quench free radicals. This quantification is known as the total ORAC value. The total ORAC value provides a relative measure of total antioxidant strength of any substance, allowing for comparison of different mixtures. A high ORAC value corresponds to a high total in vitro antioxidant capacity.
The development of the ORAC test has led to a number of commonly eaten foods being assessed in terms of total ORAC scores per serving. Similarly, particular combinations of antioxidants, such as those in nutritional formulas, can also be assessed for their total ORAC scores. This has led to the ability to determine the potential usefulness of a particular supplement in increasing overall antioxidant capacity.
When XanoMax mangosteen 10% extract was tested for ORAC value, the resulting antioxidant potential was over 3,500 ORAC units per gram of extract. This result is extremely high. ORAC values of compounds vary with their nutrient concentration, moisture content and other factors. For comparison purposes, whole blueberries, considered to be a rich source of antioxidants, had an ORAC value of 61 units per gram, while pomegranate tested at 105 ORAC units per gram.1 XanoMax mangosteen extract is a potentially rich source of beneficial antioxidants*
2. Maintains Healthy Immune Function*
Evidence from several animal and in vitro studies on various cell lines suggests that components of mangosteen fruit extract may play a role in modulating several factors important to healthy immune function. Of the active components, xanthone derivatives seem to play the major role in influencing parameters of immune function in animals and in vitro models. Mangostin is the xanthone derivative that most of these studies have focused on.
A study published in 2002 assessed the effects of mangosteen extracts on the release of histamine from rat cell lines. The comparison was made to extracts of a plant frequently used in Japan, Rubus suavissimus, which is a known inhibitor of IgE-mediated histamine release from these cells. The assay showed that the mangosteen extracts used inhibited the release of histamine from these cells more potently than the extract of Rubus suavissimus. In addition, the authors compared the two herbs for prostaglandin E2 synthesis in another rat cell line and found that the mangosteen extract potently inhibited prostaglandin E2 synthesis in this in vitro trial, whereas the other herb had no effect.2
An earlier study was performed in guinea pig tracheal and rabbit thoracic aortal tissue. In this study, alpha mangostin prevented histamine-induced contraction and was shown to be a competitive histamine receptor antagonist in the smooth muscle tissue of the trachea and aorta of the animals selected. The results seen in this laboratory study were determined to be concentration-dependent. The authors suggested that alpha mangostin should undergo further studies to determine its effects on the modulation of the histamine response.3
Further in vitro assessments point to potential actions of mangosteen components in modulating effectors of occasional inflammation in the immune system. Studies in rat glioma cells suggest that mangostins inhibit enzymatic reactions that can lead to the production of specific prostaglandins.4,5 By inhibiting these reactions, mangostins may play a role in modulating overall immune function, promoting healthy immunity.
Mangosteen and its constituents hold much promise for their potential ability to enhance immune function and promote health. In addition to being a highly nutritious food, mangosteen extract is full of antioxidant activity. It has an extremely high ORAC value and a great potential for enhancing free radical defenses in the body. Best Mangosteen 10% extract contains XanoMax, which is standardized to a high level of active mangostin, the class of compounds shown in in vitro studies to benefit certain aspects of immune function.

Free radicals are molecules which harm healthy body cells. The accumulated damage caused by free radicals is considered a primary cause of the aging process. You can dramatically slow-down this aging process (anti-aging) by combatting free radical activity with anti-oxidants.
ORAC+ ?slows the Aging Process? (anti-aging)
Extraordinary scientific research from Tufts University has evaluated the antioxidant needs of the average person PLUS the antioxidant power (referred to as Oxygen Radical Absorbance Capacity or ORAC Value) of fruits and vegetables. Their research has concluded that we need approximately 5,000 ORAC Units per day to have a significant impact on plasma and tissue antioxidant capacity. Consumption of a minimum of three servings of fruits and vegetables per day provides approximately 1200 ORAC Units. This means the average person is short approximately 3800 ORAC Units each day, depending on the fruits and vegetables they are choosing.
ORAC+ fills the gap to ?mop-up? all the body?s free radical generation on a daily basis to slow the aging process (anti-aging).
ORAC+ has been independently tested by one of the world?s foremost laboratories specializing in Oxygen Radical Absorbing Capacity (ORAC).

Oxygen Radical Absorbence Capacity (ORAC)
ORAC is an exciting and revolutionary new test tube analysis that can be utilized to test "Antioxident Power" of foods and other chemical substances. It calculates the ability of a product or chemical to protect against potentially damaging free radicals.
This analytical procedure measures the ability of a food, vitamin, nutritional supplement, or other chemical to protect against the attack by free radicals, or to act as an Antioxidant. The test is performed using Trolox (a water-soluble analog of Vitamin E) as a standard to determine the Trolox Equivalent (TE).
The ORAC value is then calculated from the Trolox Equivalent and expressed as ORAC units or value. The higher the ORAC value, the greater the "Antioxidant Power".
