Expert Q&A: Antiaging and Diet
An interview with David Grotto, RD, LDN.
At what age does the body start to decline? How can you stop that?
There's biological age and chronological age. We can't do anything about
chronological age. But with biological age, lots of things can affect that --
smoking, not getting enough sleep, a poor diet, getting too much sun
Experts say avoid the sun -- but what else helps keep skin looking young?
Eating a healthy diet absolutely makes a difference. Getting the right
nutrients is vital for repairing skin and getting new healthy cells to replace
the damaged ones. Vitamins A, C, and D are important. But there may be some
components in specific foods that help, too.
Avocados are a good source of vitamin E, which is also great for skin. In

How important are genetics to the aging process? Can you do anything to control your genes?

So there are foods naturally rich in phytoestrogens that may help keep skin
nice and supple. Soy is a good source. Beans and legumes are generally high in
phytoestrogens. Flax, too. The key with those foods is not to wait until you
turn 50 to suddenly start eating them. Start earlier eating moderate amounts of
There's a book out: Japanese Women Don't Get Old or Fat. It's very
interesting because if anybody doesn't show their age, it's Japanese women.
That's a nod to their diet historically. There definitely may be something
there -- to eating tofu and vegetables.
But we in America tend to think more is better. In Japanese culture, soy is
not the main thing on the plate. A handful of edamame, a little tofu in soup,
is enough. You don't need to eat a whole brick of tofu. More is not necessarily
