does cooking/ boiling foods change nutrition facts?

[AirKnight]

i know that proteins can get denatured from high heat, so does making an omlet or cooking chicken affect the nutrition facts?

In general, unless you are completely mutilating the food, the changes are typically minor.

But there is really no one sweeping answer here as it depends on the particular food and preparation method ... a few caveats ...

If you char the said food, there obviously will be a small loss in nutritional value.

European Journal of Clinical Nutrition - The impact of freezing and toasting on the glycaemic response of white bread
Conclusions: All three procedures investigated, freezing and defrosting, toasting from fresh and toasting following freezing and defrosting, favourably altered the glucose response of the breads. This is the first study known to the authors to show reductions in glycaemic response as a result of changes in storage conditions and the preparation of white bread before consumption.

EFFECT OF TOASTING ON THE NUTRITIVE VALUE OF BREAD
The nutritive value of bread was significantly reduced by toasting. Rat-feeding tests showed that the feed conversion ratio, calculated from weight gain and feed intake, was increased, while the protein efficiency ratio of bread was reduced significantly with toasting and with degree toasted. The changes correlated with browning intensities of toasted bread slices. So far as the nutritive value of bread is concerned, toasting, particularly to darkening, is not recommended.

to simplify the answer... yes, but not enough to matter unless it is buned to hell.

Ground meat can lose a lot of fat during cooking. I think 80 and 85% lean beef loses about 1/2 it's fat if you drain it.

Yup... Reducing Fat in Cooked Ground Beef : Quantified

The changes are only minor.

According Good Eats' Alton Brown, cooking fruits and vegetables is fine. Though the cooking process does cause a loss of some nutrients, it also breaks down cell walls, thus allowing your body to actually get more nutrients out of it.
