Query: Beware of hidden glutamates.

This is a high quality product with nice flavor but the label is misleading. This tuna is not packed in water, it is packed in so-called vegetable broth which sounds innocent enough unless you are the type of person that gets headaches after eating in a chinese restaurant. This soy broth is like virtual MSG. MSG deadens portions of your tastebuds that tastes rotten or fishy flavors and causes tumors in lab mice.If you can eat MSG/Glutamates without any problem this is an excellent product and the pouch is very convenient. I am sorry to see that Amazon no longer carries Starkist tuna in a pouch packed in sunflower oil. Their sunflower oil packed tuna is by far the best tuna I have ever eaten and would reccomend to any tuna lover.
