cooking wheatgerm loses nutritional value?
hi,
i've been experimenting with some home-made toasted oat cereal. to make it more healthy i add wheatgerm and bran. someone said on a web site that if you cook wheatgerm it loses its nutritional value. is this true? what about bran? the cereal is baked in the oven in a honey + oil mix @ 180 c. i find it hard to believe that nutrients could disappear with heat... but you never know. thanks in advance for any tips tim |

It is my understanding that this only happens when cooking in water, as the nutrients leach out in the water. I would not expect it to happen with baking or roasting, but I may be wrong. Incidentally, collard greens are one of the few foods whose nutrient value increases when boiled. No kidding, cooking makes some of the nutrients available to us that are not available raw. Strangely, the fiber content quintuples when the collards are cooked. http://www.vegparadise.com/highestperch55.html _________________________________________ Usenet Zone Free Binaries Usenet Server More than 140,000 groups Unlimited download http://www.usenetzone.com to open account |

Someone is either not reading correctly or not dividing properly. Let see the latest release I have from the USDA lists 100 grams of collards, boiled, drained, without salt, as 2.8 grams of dietary fiber. And raw is 3.6 grams of dietary fiber for 100 grams. So really 0.8 grams difference. That's not five times but more like the reciprocal, 1/5th more. I gather someone did not divide properly. I suggest using the USDA. They actually do real experiments. And those in water loss have also been done. I was surprised how little was lost in general. Very, very surprised. About the water, don't remember now. The brain is elsewhere at the moment. In any case, drink the water if concerned. But I would try to find an actual scientific article. This web stuff is very inaccurate and gets quoted over and over. USDA = United States Department of Agriculture 100 grams = 22% of a pound, almost a quarter of one pound weight. |

I think the worst was around 50%. And even relatively fragile vitamins like C or E did quite well in cooking tests. If I find the URL which lists all the vitamins tested in cooking by the USDA, it will be interesting reading because what these web sites post is not true. It's just marketing and advertising for their selfish purposes of selling more vitamins! Ask them for a reference and then see what they sputter about. An awful lot of vitamins are not destroyed. There may be unknown nutrients destroyed by cooking but the ones we know about are not destroyed to any great degree. As I recall, luteins are enhanced by cooking and that can prevent the most common form of blindness. |

Dinners were plated up in advance and left to steam in hot boxes, and apparently this was leading to vitamin deficiencies. We will say nothing about flavour or texture. Christine Who lived at home |

The times used by the USDA were for cooking not destroying nutrients in a steam table. In any case, how did they know this was leading to vitamin deficiencies? Did they actually do chemical analyses? Did they see any vitamin deficiencies? It's kind of difficult to see a vitamin deficiency immediately but there are somet that can be seen right away. Scurvy and limes would be an example, a classic one. Again, what did they see that led them to believe vitamin deficiencies were occuring? I'm curious. Scurvy was a common problem in the English navy and ancient marines but they solved it. And the cure was rather dramatic, some fresh oranges or anything with a solid vitamin C content. Limes were the weapon of choice, antisorbutic, hence the name, limeys. |
