Does boiling yams result in loss of nutrients?

[Suave_Howss]

Hello All,

I would imagine that if yams were pre-cut and peeled that they would lose a fair amount of nutrients when boiled, but I am wondering if boiling WHOLE yams (with the skin ON) will result in a significant loss of nutrients... any insight?

Is baking the only way to preserve nutrients?

dude just drink the water. When I boil yams and broccoli I mix the water, it looks like turd juice but I KNOW it's working.

Heating anything denatures it

Heating anything denatures it

In this case it denatures the Anti-Trypsin Enzymes (which inhibit protein digestion I think) and some glycoalkaloids ?

This link shows different vitamin losses for cooking http://nutritiondata.self.com/topics/processing

"Nutrients can also be "washed out" of foods by fluids that are introduced during a cooking process. For example, boiling a potato can cause much of the potato's B and C vitamins to migrate to the boiling water. You'll still benefit from those nutrients if you consume the liquid (i.e. if the potato and water are being turned into potato soup), but not if you throw away the liquid. Similar losses also occur when you broil, roast, or fry in oil, and then drain off the drippings."

Most of the vitamin losses from throwing oil would be fat soluble ones (A, E, D, etc..)

Baking seems like the best way to do it, or if you're boiling, use just enough water for boiling time and leave the lid off, so most of the water will evaporate by the time boiling is done and you have a 1/4 cup or so of vitamin water.

how are you going to eat potatoes raw?

...gotta cook them somehow, at least that's how i like them (baked), i know prodigy perfers raw foods tho.

Suave - I think the important thing to keep in mind is to not overcook any of your foods....err on the side of undercooked, that's what i do. You don't want to denature your proteins too much because this changes the funtion of the protein and same can be said with any other carbs, fats, fibrous carbs you lose the good nutrients if you overcook them.

Denaturation also has to do with salt concentration and PH levels.

cool , thanks for the feedback !! now i gotta go pick up some yams... im fresh out :-(

That's why I eat the pussy raw to get the nutritional benefits without denaturing anything.
