When you cook food does it really lose all its vitamins, fiber etc.

Not ALL of it's nutrients but a bit is lost, yes. It's best to eat fruits and veggies either steamed or fresh. Frozen is also better in nutritional value than canned foods.

So if you have a frozen dinner with a lot of veggies in it (Like Lean cusene meals) and it says 5 grms of fiber 17% Vitiman C etc, the microwave doesn't kill it either?

Cooking also releases some of the foods nutritional content. Mostly I like that cooking makes it more palatable. Some foods aren't even edible until cooked.

True.
That's why when ever I cook a soup I never discard the water drom boiling the veggies cause I don't want to lose anything

Tonight's dinner:

Individual Beef Wellington's with Blanched Asparagus and Bearnaise Sauce

Prepared and served by yours truly...

How about pan frying (no oil, I use pam, if that's eevn healthier lol)

Look at the ingredients of your Lean Cuisine. Frozen diet meals are HIGH in sodium. They have to replace the flavor somehow.

So that means it does kill the nutrients?

No hun, that means that it is not as healthy as it is made out to be. High sodium content is as dangerous as high fat content.

The best foods are fresh or frozen, steamed or baked, not boiled or fried.

I rarely eat those things, only if I'm in a hrry and can't cook but yea, agreed.

Frying deff out of the question for me haha but hwy is boiling bad?

Sodium can be like fat then right? Because I notice when I eat a lot of salty food I gain temporary weight

One thing to remember is "where salt goes, water goes."

Soooooo, if you eat a lot of salt (sodium) you tend to gain water.

Boiling is not necessarily out of the question, but nutrients leak out of the food into the water, and the water is not really usable once the food is cooked.

Ohh okay I see. Thank youu :)
