Cooking out nutrition

I just read the Muscledog article on aging food losing its nutrition, so I went ahead and looked into cooking food and losing its nutrition. Here is an article I found on MSN Health:http://health.msn.com/fitness/articlepage.aspx?cp-documentid=100153211 

I also read earlier last week that all of this loss of nutrients is a false statement.  I grill a lot and it has occured to me that the fat burns off, but does that speak for protein and vitamins as well?

PeteBauman: oh and girlling will cause some nutrient loss but i wouldn’t worry about it. the reason you are losing the fat is cause it liquefies at higher temperatures and runs off, while the protein won’t. the nutrients are lost via breakdown or decomposing, not necessarily by running off like the fat.

cooking is essentially just a chemical reaction. every time you are cooking in your kitchen, you are simply playing scientist in your own little un-sterile lab. mixing ingredients together, adding heat as a catalyst… it’s a very real analogy when you think about it.

PeteBauman: i’d like to see where you read that nutrient loss is a false statement. it’s been shown time and again that ripening, aging, or heating foods causes some nutrient loss. it may be overstated by some, and food typically won’t lose more than half it’s nutrients, but most vitamins and minerals break down with exposure to one of heat, light, oxygen or just with time.
