Antioxidants - What You Need To Know

Antioxidants in human health -

Generally, oxidative reactions continuously take place in the human body sometime with very slow rate and higher rate relative to concentration of free radicals in the cell. The free radicals may cause minor or major oxidative damages in the human body, and in most extreme cases it may cause irregularities in the cell growth cycle that accelerates the rate of cell growth, leading to a number of disorders, viz.

malignancy and malfunction in the apoptosis mechanism. To get rid of the above problems, people should continuously consume the food sources that fulfil the daily requirement of antioxidants.

The natural antioxidants are found in a variety of foods, including fruits, vegetables and cereals. Although, oxidation is an important phenomenon in human body that helps in the lysis of harmful cells. There is a variety of natural antioxidants, such as glutathione, vitamin C, vitamin A and vitamin E as well as enzymes such as catalase, superoxide dismutase and various peroxides.

At present, the consumers have been shifted their priority towards food safety over food quality. In the ancient period, in traditional herbal medicines, dietary foods were the main sources of natural antioxidant that protected them from the damage caused by free radicals. Natural antioxidants are widely used in dietary supplements and have been investigated for the prevention of number of non-communicable diseases such as cancer, coronary heart disease, and altitude sickness.

These may be a sustainable substitute for chemical preservatives in a variety of functional food products to reduce chemical hazards on human health.

This chapter covers the processing of food to incorporate the natural antioxidants in the diet that will be beneficial for human health.

Food Res Int — When this equilibrium is disrupted, it can lead to oxidative stress. Plants and animals, as well as all other forms of life, have their own defenses against free radicals and oxidative damage. Adequate antioxidant intake is important.

In fact, your life depends on the intake of certain antioxidants — namely, vitamins C and E. However, many other non-essential antioxidants occur in food.

The health benefits associated with a diet rich in plants is at least partially due to the variety of antioxidants they provide Berries, green tea , coffee, and dark chocolate are renowned for being good sources of antioxidants Meat products and fish also contain antioxidants, but to a lesser extent than fruits and vegetables 15 , Antioxidants can increase the shelf life of both natural and processed foods.

For instance, vitamin C is often added to processed foods to act as a preservative Your diet is an essential source of antioxidants, which are found in animal and plant foods — especially vegetables, fruits, and berries. Water-soluble antioxidants perform their actions in the fluid inside and outside cells, whereas fat-soluble ones act primarily in cell membranes.

Notable examples include curcuminoids in turmeric and oleocanthal in extra virgin olive oil. These substances function as antioxidants but also have potent anti-inflammatory activity 19 , Some studies even show that high doses of antioxidants increase your risk of death 23 , For this reason, most health professionals advise people to avoid high-dose antioxidant supplements , although further studies are needed before solid conclusions can be reached.

Eating plenty of antioxidant-rich whole food is a much better idea. Studies indicate that foods reduce oxidative damage to a greater extent than supplements. For example, one study compared the effects of drinking blood-orange juice and sugar water, both of which contained equal amounts of vitamin C.

It found that the juice had significantly greater antioxidant power The best strategy to ensure adequate antioxidant intake is to follow a diet rich in various vegetables and fruits, alongside other healthy habits However, low-dose supplements, such as multivitamins, may be beneficial if you are deficient in certain nutrients or unable to follow a healthy diet.

Studies suggest that taking regular, high-dose antioxidant supplements may be harmful. If possible, get your daily dose of antioxidants from whole foods, such as fruits and vegetables.

Adequate antioxidant intake is essential to a healthy diet, although some studies suggest that high-dose supplements may be harmful. The best strategy is to get your daily dose of antioxidants from healthy plant foods, such as fruits and vegetables.

Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available. Coffee is incredibly high in antioxidants. The body processes food and reacts to the environment it is because of the free radicals which act as the waste substances produced by cells trusted source.

Oxidative stress is caused if the body remove free radicals efficiently and cannot process, by this body functioning does not take place and it also harm cells.

The other term used for free radicals are Reactive Oxygen Species ROS. Factors which increase the free radicals production in the body can be external, such as pollution, UV exposure and cigarette smoke.

Antioxidants help to neutralize free radicals in our bodies, and it also boosts the overall health. Plant-based foods are the best sources of antioxidants, especially vegetables and fruits.

To gain some specific antioxidants, we must try to include the below nutrients food in our diet:. Vitamin C : Most vegetables and fruits, especially oranges, bell peppers and berries. Vitamin E: Seeds and nuts, other vegetable oils, sunflower and green leafy vegetables. Beta-carotene: Brightly coloured vegetables and fruits, such as peas, carrots, mangoes and spinach.

Selenium: In this it consists of rice, other whole grains, wheat, and corn as well as eggs, legumes, cheese and nuts. Whereas some other foods that are entrust to be friendly sources of antioxidants which include:.

The most antioxidants are found in foods with rich vibrant colours. The following foods are good sources of antioxidants. There are more health benefits and nutritional information in the below mentioned foods:.

Antioxidants usually have good press for their beneficial effects helping to prevent disease, but these powerful compounds may also have a dark side.

Antioxidants are Antioxidants in human health to prevent the formation and Antioxidnats the actions heqlth reactive oxygen and nitrogen species, African Mango seed hair growth are generated in jealth and cause damage to Ih, lipids, proteins, and other biomolecules. Endogenous antioxidant defenses superoxide dismutases, H2O2-removing enzymes, metal binding proteins are inadequate to prevent damage completely, so diet-derived antioxidants are important in maintaining health. Many dietary compounds have been suggested to be important antioxidants: The evidence for a key role of vitamins E and C is strong, but that for carotenoids and related plant pigments is weaker. Interest is also growing in the role of plant phenolics, especially flavonoids. Some antioxidants can exert prooxidant effects in vitro, but their physiological relevance is uncertain. New research shows Body fat calipers for home use risk healgh infection from prostate biopsies. Antioxidants in human health at work is linked to Antioxidants in human health blood pressure. Antioxodants fingers and toes: Poor circulation or Raynaud's phenomenon? Some vitamins and minerals — including vitamins C and E and the minerals copper, zinc, and selenium — serve as antioxidants, in addition to other vital roles. Because free radicals lack a full complement of electrons, they steal electrons from other molecules and damage those molecules in the process.
