Quiltmaker, I know what you mean. You really do have to educate yourself.
I also get tired of scares and stuff like that but so much of our food is really bad.
Our immune systems are there to help us but I really try to watch what I put in my body. I'm the only one who can. :)
Several years ago my liver enzymes were elevated and long story short I was eating wayyyyy too much sugar. I changed my eating habits and my enzymes returned to normal. It was scary for me but good thing I changed. Now it's only the occasional coke or pepsi. I still eat sweets but far less and I feel a lot better. I'm not fanatical but I swear my liver enyzme tests scared the heck out of me!!
My body just doesn't handle all that stuff. Kind of off topic, sorry!! :D
