Tracking my nutrition

Hello!
Just joined this today! In the past I have used other apps to track my nutrition, but this seems way more accurate and offers more results on food to include. I have been really trying to maintain my vitamin/calcium/iron intake and watchdog my sugar and salt. I have cut sugar down significantly since I quit pop. I still find it hard to dodge sugar and salt though. I always double my intake! I thought I was eating "healthy" too.
As far as fitness goes, I have just transitioned jobs from an active one to a fully sedentary one. I am very worried about that. I have started to jog/walk about 45 minutes everyday and I try to stay active around the house when I'm not at work.
My family tells me I worry too much about this stuff, but I feel like you can't worry enough. In most American societies today the junk food is being consumed at an alarming rate. I recently watched Fed Up, which I recommend to everyone. It is extremely eye opening, but very important info for us all. My family also is made up of mostly obese adults, so I really want to help them. I will be getting them on here soon and will try to help them along the path to a healthy life style!
Thanks all! Let's get healthy and stay that way!
