What are sirtuins and how do they impact the aging process?

What are sirtuins and how do they impact the aging process?

Proteins under study: From studies in yeast, sirtuins (sir2 proteins) are believed to have some effects on aging, on cell death, on stress resistance (such as in situations of food scarcity), etc... Researchers are trying to find out if there are anti-aging effects in mammals. Some believe resveratrol activates a sirtuin and possibly extends lifespan, but so far research with mammals has not shown any such benefit. ...Read more

Which types of medicines slow the aging process?

Which types of medicines slow the aging process?

None: They have not made such a product. Nutritional anti-oxidants are real and popular, but overall, i think that good living practices - food, rest, activity level, companionship, interests - all of good quality and all in moderation are probably the best ways to feel and look as young as you can. Some aging patterns are inherited, but living well is always a good idea. ...Read more

If I have ddd and bulging disc at the age of 28, will I have for sure more serious issues with my spine with the aging process? P.S: i'm a smoker.

Aging spine: No you will not. The presence of degenerative changes and / or buldging disks is not uncommon as we grow older. In fact the changes which are often identified on imaging like MRI studies rarely result in symptoms. In some cases symptoms may develop or persist to the point surgery may become necessary. Certainly smokers healer less readily compared to non smokers. ...Read more

What does alcohol do to the body? Does it speed up the aging process? I'm an aspiring athlete, so could drinking hurt my career?

What does alcohol do to the body? Does it speed up the aging process? I'm an aspiring athlete, so could drinking hurt my career?

Alcohol risks: FDA wouldn't approve alcohol for human consumption as it is hepato-toxic (liver cirrhosis). Aging per se in not an issue. It can make you fat due to lots of non-nutritional calories in alcohol. Also there are obvious risks when drunk. On the other hand it does lubricate the soul, so only you can decide if you want to drink. "Everything in moderation, including moderation" Oscar Wilde ...Read more

Mri with findings of mild chronic white mater supratentorially in periventricular region. Is this something to worry about or normal aging process.

Mild ischemic change: Signal abnormalities in the supratentorial white matter, which are best appreciated on the flair sequence of the MRI exam, in general are not very specific and may be the result of various processes. However, in older adults these are very common and in most cases the result of small vessel ischemic changes; essentially considered a normal part of aging given the high prevalence. ...Read more

Can omega 3 slow the aging process?

Can omega 3 slow the aging process?

No real evidence: You'll hear conflicting claims even from informed physicians as to whether omega 3's offer a real cardiovascular benefit. My own reading of the last three big studies leads me to skepticism but others i respect here will disagree. They has use as anti-inflammatories. There's nothing whatever to suggest they actually slow the biological clock independent of vascular health. ...Read more

Is moderate generalized cortical atrophy part of the normal aging process? I am 62.

Is moderate generalized cortical atrophy part of the normal aging process?  I am 62.

Cortical atrophy: Yes. The brain is like a muscle. If we don't use muscles, then they atrophy. Likewise with the brain we need to keep it stimulated with mental and physical exercises. Performing fine motor tasks or those that require significant focus increase brain function. Toxins such as tobacco and alcohol increase the rate of brain atrophy. Check out Lumosity.com. ...Read more
