Do we need DNA in a healthy diet?
« on: 19/02/2009 09:30:02 »
JessicaH asked the Naked Scientists:
Naked Scientists,
Thanks for the informative and entertaining shows each week!  
Is DNA an essential part of the diet?   You always hear that proteins are important in your diet so you can make your own proteins, but does the same logic work for DNA?  
Could you have a DNA deficiency if you somehow could subsist on synthetic sources of  fats, proteins, carbohydrates, and vitamin pills?
To lapse into some  science-speak, I mean does your stomach  break down the DNA of the fruits, veggies, and proteins we eat into nucleotides and re-use them?

What do you think?

I don't see how DNA can't be a part of the diet [???][???]

I meant this more as a hypothetical situation, but that's actually interesting to think of how you can eat without eating DNA.  Here's my menu:

Take a bottle of Sports Drink and add some purified vegetable oil and protein powder mix.  Drink with a complement of vitamin pills.  Perhaps for dessert, eat purified lard.

In this case you'd get carbohydrates and electrolytes from the Sports drinks, fats from the oil and lard, protein from the powder mix, and hopefully most of the essential vitamins and nutrients from the pills. 

So could someone live very long on a totally synthetic diet like this? 

And I'm still wondering where nucleotides come from!

Human beings have all the necessary proteins for a complete nucleotide synthesis and breakdown.
In other words, no we don't require DNA in our diet.
