New Research on Old Age People
Old people with no regrets live happy

According to the study, conducted by German scientists,
If an individual has had a few regrets, it might be to best to let them go, as
dwelling on what might have been makes for a miserable old age. They say that
regrets naturally decrease as we get older - as we try to make the most of the
time we have left and have fewer opportunities for second chances.
A super antioxidant, immune system booster
Experts are
currently learning more about glutathione, a small molecule that is produced by
the body and found in every cell. This naturally occurring substance acts as a
super antioxidant, immune system booster, detoxifier and cell cycle regulator.
It is said to help the body repair damage caused by infection, injury, stress
and even aging.
Combating free radicals with antioxidants is one way to
keep the worst effects of old age at bay. "Vitamin E cream is something
that we can put on the skin to stop protein degradation," Easton points
out. "People take Vitamin E supplements or eat foods that are high in
vitamin E. The other thing you can do is eat lots of onion and garlic because
it has these antioxidants. Or of course the most popular one is to drink lots
of red wine."
However, while diet
and exercise still matter in the fight against ageing, lifestyle is not the
only factor at play. Stigers' and Easton's research may lead to the development
of new drug treatments; meanwhile, genes also play their part - some of us
simply have better defenses against free radicals than others.
Tomatoes can save you from high cholesterol: Tomatoes may
be an effective alternative to drugs in lowering cholesterol and BP and in
preventing heart disease. A bright red pigment called lycopene found in
tomatoes and to a lesser extent in watermelon, guava, papaya and pink
grapefruit has antioxidant properties that are vital to good health.
Karin Ried and her colleague Peter Fakler from the
University of Adelaide are the first to summarise the effect of lycopene on
cholesterol and blood pressure (BP), analysing the collective results of 14
studies over the last 55 years.
Damaged DNA in Old Age Causes Pneumonia
A team of researchers from The University of Texas Health
Science Centre San Antonio has revealed in May 2011 that DNA in old age gets
damaged which makes elder people vulnerable to community-acquired pneumonia.
Community-acquired pneumonia is a disease caused due to infection in the lungs.
The symptoms of the disease include difficulty in breathing, chest pain, fever
and cough. It has been observed that about 1 billion adults all over the world
are at the risk of pneumonia. Out of them 800 million adults are older than 65
and an estimated 210 million are suffering from chronic obstructive pulmonary
disease (COPD).
Both age and
COPD, by scientists, have been associated with senescent cells, which are
unable to die due to dysregulated function. It has been told that these cells
carry increased levels of proteins which is disease-causing bacteria stick to
and co-opt to invade the bloodstream. Moreover, the cells discharge out
molecules that increase inflammation, and cause the same reaction in the normal
cell. A senior author of the study Carlos Orihuela has said that by controlling
the inflammatory molecules’ release could short-circuit pneumonia risk in the
elderly.
