How to slow down Aging

No one wants to grow old. The body constantly battles against this process. Free radicals are responsible for the changes and shortening of the DNA in our cells, which in turn causes the visible changes of ageing...click & see

Free radicals are compounds created when a molecule in our body gains or loses an electron, rendering it unstable. The commonest free radicals are known as ROS (reactive oxygen species).

Antioxidants act as scavengers, removing the destroyed or fragmented DNA caused by free radicals. These days they are being prescribed as the panacea of all ills. Conditions ranging from poor immunity, male infertility, heart attacks, diabetes, cancer to even ageing are said to benefit from antioxidant supplements.

Antioxidants occur in a variety of foods, especially coloured (red, yellow, green, purple) fruits and vegetables. They are not heat stable, so it is better to eat the fruits or vegetables raw. People who eat 4-6 helpings of fruits and vegetables a day have a lower incidence of cancer and live longer. On the other hand, they tend to be health conscious, exercise, have healthier lifestyles and are conscious of body weight.

A large amount of ROP is released during exercise. So taking antioxidant supplements should decrease recovery time. A number of studies have demonstrated that this is not the case. Ironically, taking antioxidant supplements actually slows down recovery.

Patients with cancer are often advised to take supplements of megavitamins and antioxidants. They may actually be detrimental. High doses of betacarotene increases the risk of lung cancer in smokers. Vitamin E can increase the risk of prostate cancer and high doses of vitamin C the risk of bladder cancer. High-dose supplements of antioxidants are linked to worse cancer outcomes, especially in smokers.

Instead of antioxidants, if we follow the following rules and do them regularly we could get better result....click & see

1)Do some freehand exercise (yoga) daily.

2) Walk, jog or run 40 minutes a day

3) Eat 4-6 helpings of fresh fruit and vegetables a day

4) Never smoke or spend time around smokers

Fight These 4 Causes to Live Long

You can slow down your aging process and help stave off heart disease, cancer, and diabetes. U.S. News & World Report offers some tips on how to do it:

1.Free radicals. Free radicals are chemically unstable molecules that attack your cells and damage your DNA. You can limit your exposure to them by avoiding cigarettes, trans fats, charred meats, and other sources.

Organic fruits and vegetables will also limit your exposure to pesticides and herbicides, which contain the harmful molecules.

2.Inflammation. Inflammation is a major player in many diseases of aging, including cancer, diabetes, heart disease, and Alzheimer’s. One way to avoid it is to follow a Mediterranean-style diet.

Other great anti-inflammatory foods include turmeric, dark chocolate, and the anti-aging chemical resveratrol. Exercise is another great way to lower inflammation.

3.Glycation. Glycation is what happens when sugar mixes with proteins and fats to form molecules that promote aging. Advanced glycation end products, or AGEs, are thought to accelerate your aging process by churning out free radicals and promoting inflammation. One way to avoid ingesting AGEs is to turn down the heat when you cook. The browning effect of high-heat cooking causes these molecules to form. Limiting your intake of sugar-filled foods in general will also help.
4.Stress. Stress initiates the release of a variety of hormones that make your pulse race and cause your blood pressure to rise. The hormone cortisol, released to lessen these effects, also creates problems when it remains chronically elevated. Try practicing relaxation techniques to help manage stress, and get enough sleep every night.

Paracetamol Ups Asthma Risk in Kids

 

 

Infants who have been given the common pain reliever paracetamol may have a higher risk of developing asthma and eczema by the time they are 6 or 7, a large study covering children in 31 countries has found.

CLICK & SEE

The findings were published in the journal Lancet together with two other studies, which found that runny noses and wheezing early on in life may be strong predictors of asthma.

In one study, researchers pored through data provided by parents of more than 205,000 children and found paracetamol use in the first year of life was associated with a 46% higher risk of asthma by the time the children were 6 or 7 compared to those never exposed to the drug. It is used to relieve fever, minor aches and pain, and is used in a liquid suspension for children.

Medium use of paracetamol in the past 12 months increased asthma risk by 61%, while high dosages of once a month or more in the past year raised the risk by over three times. Medium use was defined as once per year or more, but less than once a month.

Suspicions of a possible link between paracetamol and asthma emerged when experts observed an increased use of the drug to a simultaneous rise in asthma prevalence worldwide.

Some experts think antioxidants, which stop unstable molecules known as free radicals from doing too much damage, can lower the risk of cancer, heart disease and other ailments. “Paracetamol can reduce antioxidant levels and… can give oxidative stress in the lungs and cause asthma,” one of the researchers, Richard Beasley at the Medical Research Institute of New Zealand, said.

Antioxidant Cure For Wrinkles?

Beauty care starts at home, by taking your vitamins regularly

A new method to fight off wrinkles.
Women may soon no longer have to turn to plastic surgery to get rid of those pesky wrinkles, thanks to a researcher at the Hebrew University Faculty of Agriculture, Food and Environmental Quality Sciences who has developed a new method to fight wrinkles.

The method has been developed by Dr Orit Bossi under the supervision of Zecharia Madar, the Karl Bach Professor of Agricultural Biochemistry at the Hebrew University, and Prof Shlomo Grossman of Bar-Ilan University.

Antioxidants operate against free radicals which cause a breakdown of many tissues in the body, including the skin. When found in small quantities in the body, free radicals are not harmful and are even involved in various physical processes.

When there is an excess of free radicals, however, as occurs during normal aging or as a result of excessive exposure to ultra-violet radiation from the sun, the result, among other things, is a breakdown of the collagen and elastin fibres in the skin. When this happens, there is a loss of skin elasticity and the formation of wrinkles. “A problem with many of the commercial antioxidants found today in the market that are said to retard the aging process is that they oxidise quickly and therefore their efficiency declines with time,” said Dr Bossi.

“Vitamin C, for example, oxidises rapidly and is sensitive to high temperatures. This is also true of the antioxidant EGCG which is found in green tea, and vitamin E. As a part of her research, Dr Bossi conducted experiments on mice skin tissue, which resembles that of humans. She applied her antioxidant on two skin cell groups — those which had been exposed to the sun’s rays and received her antioxidant and those which also had been exposed to sun but did not receive the antioxidant. The untreated cells showed a rise in free radicals causing wrinkles, while those cells which had been treated showed no significant increase in the free radicals level.
