Another study, published in September in the British Journal of Sports Medicine , suggested that reducing the amount of time sitting may protect against telomere shortening and extend lifespan. Last month, Dr. Mitochondria are described as the "powerhouses" of cells, giving them the energy to function, but previous research has also associated mitochondria with oxidative stress. In their study, published in The Embo Journal , Dr.
Passos and colleagues increased mitophagy - a process cells normally use to get rid of faulty mitochondria - in aging human cells, enabling them to eradicate all mitochondria. They found that eliminating mitochondria from the aging cells triggered a rejuvenation process, reducing markers of cellular aging to levels that are normally seen in younger cells. Now we are a step closer to devising therapies which target mitochondria to counteract the aging of cells," says study coauthor Dr.
Clara Correia-Melo. When it comes to aging, one of the biggest concerns is how it will affect our cognitive function. The majority of people will see a decline in cognitive skills as they age.

This is because certain areas of the brain - particularly those linked to learning and memory - shrink as we get older, interfering with connections between nerve cells. Others may experience a more severe form of cognitive decline, such as Alzheimer's disease , which affects around 5. But increasingly, researchers are uncovering medical strategies that show promise for reversing brain aging. Last month, MNT reported on a study published in The Journal of Neuroscience , in which researchers successfully reversed aging in the brains of rats.
The team - from the University of California-Irvine - gave 11 rats a drug called ampakine every day for 3 months, while a further 12 rats received a placebo. From brain scans conducted during treatment, the researchers found "middle-aged" rats in the placebo group had shorter dendrites - branch-like fibers that aid brain cell communication - and fewer dendritic branches than the "adolescent" rats that received the placebo.
The middle-aged rats that received ampakine, however, were found to have dendrites and dendritic branching that was comparable to those of the adolescent rats, suggesting that ampakine may be a promising compound for reversing brain aging. This paper is saying that may not be true. While medical research certainly seems to be on the verge of finding promising strategies to reverse the aging process, it is likely to be a long time before telomere-lengthening medications hit the market.
But in the meantime, there are a number of things we can do to help reduce the effects of aging. It goes without saying that regular exercise is good for health, but numerous studies have hailed exercise for its beneficial impact on aging. Last October, MNT reported on a study suggesting that aerobic exercise - such as walking or cycling - from middle to older age is associated with healthier brain aging , while an earlier study linked aerobic exercise to reduced risk of Alzheimer's.
Other research - published in PLOS One in - suggested that running several times a week may slow the aging process for older adults, promoting better mobility and quality of life, while another study found running minutes daily could add 3 years to life expectancy. Eating a healthy diet is also considered a key factor for healthy aging; last October, a study published in the journal Neurology suggested that following a Mediterranean-style diet may protect against brain aging. The National Institute on Aging recommend following a diet that includes fruits, vegetables and grains - particularly whole grains - low-fat or fat-free dairy products, seafood, lean poultry and meats.
They also recommend limiting the amount of saturated and trans fats, as well as levels of cholesterol , salt and added sugars.

To start, here are some powerful ingredients to look for when picking an anti-aging product:. Retinoids are the gold-standard of anti-aging ingredients.
