Home made beef broth is excellent for healing Leaky Gut and to drink when unwell. Traditionally broth was made just from meat bones and simmered for hours to remove the gelatin, marrow and goodness from them. These days vegetables are also added to give extra flavour. If purchasing store bought broth/stocks, read your labels as many companies have changed the name of MSG to yeast extract. Organic or free range brands are available. I keep one on hand for emergencies. I get the butcher to cut my beef bones up so it's easy for the marrow and nutrients to be released easily. I prefer to making my broth in a slow cooker. I keep ice block trays filled with broth in the freezer ready for when just a small amount is required in a recipe.
