Store bought stock cubes can be bad for you because they contain a lot of added salt to them.
When you make your own stock then it's healthier to drink or consume because of the less salt content.
But even store bought stock cubes are okay to drink or use in moderation and I like to add a stock cube to some boiling water.
Then drink the glass of stock after cools down to just warm when I have a cold as it helps me.
You can drink stock cubes or chicken bouillon cubes.
When I'm sick I boil some water and add some stock cubes or chicken bouillon cubes to the boiling water and make a good chicken broth or other stock drink.
Just like you can add the chicken bouillon cubes to your recipes you can drink the chicken broth made from the bouillon cubes as well.
You can also add some parsley or herbs to the broth and make it even healthier.
I love to also drink chicken broth warmed up during cold weather and it's healthy for you.
While chicken broth from the bouillon cubes will not cure a cold or other illness the chicken broth from the bouillon cubes can provide you with nutrients and help you feel better sooner.
