Free radicals, antioxidants and functional foods: Impact on human health
Free radicals are often used in the same sentence with cancer, It also dives into their relationship and explains how it affects you through As their name suggests antioxidants, are molecules which inhibit oxidation of other. Global HD · Glossary · HD in a Nutshell · Helpful Links · Home · HOPES Brain Compounds called antioxidants act as free radical scavengers by initiating Free radicals are atoms or molecules that are highly reactive with other cellular by stealing their electrons through a process called oxidation. Free radicals are molecules with unpaired electrons. They also may have a link to aging, which has been defined as a gradual Antioxidants are molecules in cells that prevent free radicals from taking electrons and.
Many of these are present in medicinal plants. Indian systems of medicine believe that complex diseases can be treated with complex combination of botanicals unlike in west, with single drugs. Whole foods are hence used in India as functional foods rather than supplements. Some medicinal plants and dietary constituents having functional attributes are spices such as onion, garlic, mustard, red chilies, turmeric, clove, cinnamon, saffron, curry leaf, fenugreek, and ginger.
Some herbs as Bixa orellana and vegetables like amla, wheat grass, soyabean, and Gracinia cambogia have antitumor effects. Other medicinal plants with functional properties include A. Antioxidants prevent free radical induced tissue damage by preventing the formation of radicals, scavenging them, or by promoting their decomposition.
Synthetic antioxidants are recently reported to be dangerous to human health. Thus the search for effective, nontoxic natural compounds with antioxidative activity has been intensified in recent years. In addition to endogenous antioxidant defense systems, consumption of dietary and plant-derived antioxidants appears to be a suitable alternative.
Dietary and other components of plants form a major source of antioxidants.

The traditional Indian diet, spices, and medicinal plants are rich sources of natural antioxidants; higher intake of foods with functional attributes including high level of antioxidants in antioxidants in functional foods is one strategy that is gaining importance.
Newer approaches utilizing collaborative research and modern technology in combination with established traditional health principles will yield dividends in near future in improving health, especially among people who do not have access to the use of costlier western systems of medicine.

Free radicals and antioxidants in Human Health: Current status and future prospects.
The involved changes can cause mutations, they are also cancerous and terategenous. Neither of these changes is pleasant. When they are produced, oxidative stress occurs through the mentioned targets.
An increase in oxidation of these molecules is associated with an important number of diseases, including inflammation. Under normal conditions, our body is well adapted to scavenge remaining ROS, thus maintaining their numbers at an ideal and manageable level. They can suppress the growth of tumors. Moreover, chemotherapy often kills cancer cells by increasing ROS stress. But generally, higher levels of oxidative stress are considered undesirable for healthy cells.
This is where the antioxidant capabilities of our body come in. This protein-controlled response is vital to maintain a enough balance of ROS in our bodies. Namely, oxidative damage is the result of a higher oxidative stress baseline.
By now you might be wondering what causes oxidative stress. However, another important source is cigarette smoke. And not only active smoking, passive smoking causes significant increases in oxidation of the mentioned molecules as well. Physical stress working out causes an increase in ROS too. Are you advocating not to be physically active? There is a slight and short-term increase in free radicals.
It is believed this increase is a triggering mechanism or signal which allows our body to up regulate its natural antioxidant production. To put it in simple terms, you have an increase in free radicals which send a message to your body to increase the production of antioxidants. These counter the increase again and homeostasis reigns once more. There is one more thing that needs mentioning in this mix — antioxidants.
Antioxidants As their name suggests antioxidants, are molecules which inhibit oxidation of other molecules. They are comprised of endogenous, produced by our body, and exogenous, we get them through our diet, antioxidants. In the past it was believed food containing antioxidants are the Holy Grail against cancer. However, large clinical trials with limited numbers of antioxidants, by that I mean few antioxidants out of all available ones, suggested that supplementing with a few antioxidants in large numbers may actually be harmful.
They have a synergistic effect You need to eat a variety of antioxidants for them to work correctly.
