Is it bad to use a blender with protein powder
Is it true that using a blender with protein powder, like whey, is bad because the blender can break up the amino acids? This sounds crazy to me, but I've heard it more than once, so I thought I'd ask.
The best I could find was this forum. This post
Mechanical agitation will have no effect on the chemical bonds of the protein. It's like saying that a blender will break up water into hydrogen and oxygen. Last time I checked that didn't happen.
As long as you don't throw the shake into the microwave you are fine
seemed compelling, but it didn't exactly cite anything to back it up.

It won't hurt the protein powder. Many people use a shaker or a blender. Blender is popular when mixing with fruit to make a smoothie type of product.
Mechanical agitation can denature proteins, so that the proteins will no longer function correctly in their original state.
But, it's likely the proteins are already denatured as a consequence of manufacturing. And, your digestive system will break down the proteins into amino acids anyway, in order to rebuild them into new proteins.
Mechanical agitation (by a blender) cannot break up amino acid components, which are molecular.
Therefore, I cannot imagine that blending the protein will make any difference to the nutritional value.
Amino acids can be denatured because of heat..and heat is produced from the movement of the blades of the blender..so yes theoretically amino acids can be denatured this way
