Getting natural benefits of antioxidants
Antioxidants: popular for last 10 years!
Around a decade ago, scientists at Harvard University made an amazing discovery.
They found that people who ate more fruit and vegetables didn’t seem to suffer from
and other serious illnesses, as much as those who had a
less healthy diet.
Not only that, but they did some experiments, and revealed that fruit and veg contain potent chemicals called antioxidants, which were probably the mysterious life-saving ingredient.
Antioxidants became hugely popular as a result, especially in supplement form, and millions of people began taking them in the hope of warding off disease.
Then, just as suddenly, a few years ago antioxidants suffered a fall from grace. Some scientists started wondering whether they had the same positive effects inside the body as they do in test tubes, and it sparked off an international debate.
Antioxidants - getting scientists exited
It’s a particularly exciting arena of research for scientists, because the potential health benefits of antioxidants are huge.
A great deal of time and money is being invested in trials and studies on them, and we should soon have a more exact picture of how they work. In the meantime, it’s still good news: many doctors have come out in support of antioxidants, especially with regard to their effects on
and degenerative disease.
So what exactly are they?
Antioxidants are basically the super-heroes of the body’s internal cleaning team.

Without the requisite army of antioxidants in the body, free radicals would ravage the tissues, causing it to
and develop a host of unpleasant health conditions.
Where can I find them?
Some of the most powerful antioxidants are those you’ve probably already heard about:

Flavonoids (or bioflavonoids)
give plants their yellow, red or blue colours and are found in high quantities in certain fruits, herbs and vegetables, such as green tea (Camellia sinensis), and citrus fruits.
They’re often called “nature’s biological response modifiers” because they help us react appropriately to viruses, carcinogens and allergens, by giving a boost to the immune system.

can help you fight fatigue, lose weight, and strengthen your immune system.
Beta-carotene and lycopene, among other carotenoids, are another type of plant pigment, giving carrots their characteristic orange colour, for example, and making tomatoes red.
There are several dozen carotenoids in the foods that we eat, mainly in fruit and vegetables, and most of these carotenoids have antioxidant activity (lycopene is probably the most potent kind).
We all know that carrots are good for the eyesight, and that’s because of their beta-carotene content. But did you know that tomatoes help reduce the incidence of prostate cancer?
is one of the carotenoid xanthophylls (yellow pigments) found in spinach, and is also great for the eyes as well as helping to prevent lung cancer.
Yet another kind of yellow pigment also wards off disease:
It comes from the roots of the turmeric plant and can be used to treat
The B vitamins are eight water-soluble vitamins that are important for cell metabolism, and promote cell growth and division. They also maintain muscles and skin, improve the immune system and nervous system. Together, they help ward off stress, depression and
Folic acid and folate (the anion form) are forms of the water-soluble Vitamin B9 found in leaf vegetables, peas, fortified cereal, sunflower seeds and liver. They’re necessary for the production and maintenance of new cells, especially during childhood and pregnancy. Folate is required for making DNA and preventing aneamia and even

as well as brain diseases including Parkinson’s disease and epilespy, and may additionally help HIV sufferers keep their antioxidant levels from dropping.
To be sure of getting the correct dose of antioxidants, make sure you consume at least five largish portions of various fruit and vegetables every day. In addition, you can boost that intake with a
