I didn't know there was a difference between brands of gelatin. I had gotten this brand through the Radiant Life company ([...]), and it had a pleasant, gummy smell when mixed in hot water. Then I got Knox gelatin from a store, and to be frank, it smelled like pure sh**. I guess they figure people are going to be mixing it with sugar and stuff, because I don't know how they could stand by that product. I think I'll go with this brand again.
I believe gelatin could be a food that heals. "Good broth cures anything" is a South American proverb. It could be because it is a protein that DOESN'T have tryptophan. See more in this article: [...].
And it has to be a broth that has GELATIN. You can tell store-bought broths don't have an ounce of gelatin, because they absolutely do not GEL in the fridge. They usually have MSG as well. I don't know what it is, but it's not broth. If you've never made your own broth, you'll be surprised that it turns like jello in the fridge.
