Stay Young--Eat Berries

Posted Jan 11 2009 3:04pm
Time moves on, and our bodies slowly show the ravaging effects of living. Yes, we age and our cells accumulate errors when they reproduce. I have described the cellular effects of aging to my students by comparing it to making a copy of a copy of a copy and so on.

Aging has to do with what is known as oxidative stress. That is the errors associated with cell division from the presence of free radicals. Free radicals are those nasty molecules that have an unpaired electron. These bad boys like to latch on to other molecules and wreak havoc. So reducing oxidative stress can help keep our cells healthy and reduced the effects of aging.

We can reduce oxidative stress with molecules called antioxidants. Some vitamins are antioxidants as well as other molecules such as beta carotene. Another antioxidant molecule is pterostilbene which is found in berries.

In fact researchers from Tufts University and the Agricultural Research Service (ARS) tested the effects of pterstilbene on rats. The researchers first tested the effects of pterstilbene on the oxidative stress in cell cutltures. They then tested it on groups of rats including one with a low concentration of pterstilbene, one with a high concentration and a control group.

They found that the group with high concentration of pterstilbene showed significant reversal of cognitive decline and improved memory.

So we could say that berry extract helped to reduce the effects of aging (at least in rats). This lends more support to the beneficial effects of antioxidants. I know I take them and recommend them to many others.

Just one more piece of the aging puzzle...
